A Foreman installation will always contain a central Foreman instance that is responsible for providing the Web based GUI, node configurations, initial host configuration files, etc. However, if the Foreman installation supports unattended installations, then other operations need to be performed to fully automate this process. The Smart Proxy manages remote services and is generally installed with all Foreman installations to manage TFTP, DHCP, DNS, Puppet, Puppet CA, Ansible, and Salt.
A Smart-Proxy is located on or near a machine that performs a specific function and helps Foreman orchestrate the process of commissioning a new host. Placing the Smart Proxy on or near to the actual service will also help reduce latency in large distributed organizations.
This section will be updated prior to the next release.
This is the first release to provide Enterprise Linux 9 packages. Enterprise Linux 9 comes with Ruby 3 and it may affect your templates. Right now there’s no guidance on upgrading. Because of this it’s considered experimental. Foreman 3.11 plans to provide this. Users are encouraged to test and provide feedback.
The foreman-debug package is no longer installed by default, and it is now required to be installed separately.
foreman-maintain backup snapshot
foreman-maintain backup snapshot
is now deprecated and will be removed in a future release.
Please use other backup types to replace your use of snapshot.

The Foreman installer is a collection of Puppet modules that installs everything required for a full working Foreman setup. It uses native OS packaging (e.g. RPM and .deb packages) and adds necessary configuration for the complete installation.
Components include the Foreman web UI, Smart Proxy, a Puppet server, and optionally TFTP, DNS and DHCP servers. It is configurable and the Puppet modules can be read or run in “no-op” mode to see what changes it will make.
The installation will require 4GB of memory, see System Requirements for more information.
The Foreman packages and installer are tested on AlmaLinux 8, AlmaLinux 9, CentOS Stream 8 and CentOS Stream 9, but other RHEL derivatives can work because they’re similar. Sometimes additional work may be needed. For any queries for these platforms raise a question in discourse support section
The Foreman installer uses Puppet (6 or later required) to install Foreman. This guide assumes that you have a newly installed operating system, on which the installer will setup Foreman, a Puppet server, and the Smart Proxy by default. It’s not advisable to follow the steps below on an existing system, since the installer will affect the configuration of several components.
To provide specific installation instructions, please select your operating system:
Enable Puppet's 7.x repository:

ping $(hostname -f)
shows the real IP address, not 127.0.1.1. Change or remove this entry from /etc/hosts if present.
The installation run is non-interactive, but the configuration can be customized by supplying any of the options listed in foreman-installer --help
, or by running foreman-installer -i
for interactive mode. More examples are given in the Installation Options section. Adding -v
will disable the progress bar and display all changes. To run the installer, execute:
After it completes, the installer will print some details about where to find Foreman and the Smart Proxy. Output should be similar to this:
Over the last year, Foreman community members have been open-sourcing Red Hat documentation to make more comprehensive guides available to Foreman users. At the moment, the following guides have been migrated to a work-in-progress Foreman and Katello documentation site. This project is not yet complete, but you might find useful information in some of the following guides:
After installation, the Foreman installer will have set up a Puppet server on the host, fully integrated with Foreman. First run the Puppet agent on the Foreman host which will send the first Puppet report to Foreman, automatically creating the host in Foreman’s database.
In Foreman, click on the Hosts tab and your Foreman host should be visible in the list with an “O” status. This indicates its status is OK, with no changes made on the last Puppet run.
Next, we’ll install a Puppet module for managing the NTP service from Puppet Forge to our “production” environment (the default):
In Foreman, go to Configure > Classes and click Import from hostname (top right) to read the available Puppet classes from the Puppet server and populate Foreman’s database. The “ntp” class will appear in the Puppet class list if installed correctly.
Click on the “ntp” class in the list, change to the Smart Class Parameters tab and select the servers parameter on the left hand side. Tick the Override checkbox so Foreman manages the “servers” parameter of the class and change the default value if desired, before submitting the page.
Change back to the Hosts tab and click Edit on the Foreman host. On the Puppet Classes tab, expand the ntp module and click the + icon to add the ntp class to the host, then save the host.
Clicking the YAML button when back on the host page will show the ntp class and the servers parameter, as passed to Puppet via the ENC (external node classifier) interface. Re-run puppet agent --test
on the Foreman host to see the NTP service automatically reconfigured by Puppet and the NTP module.
Other hosts with Puppet agents installed can use this Puppet server by setting server = foreman.example.com
in puppet.conf. Sign their certificates in Foreman by going to Infrastructure > Smart Proxies > Certificates or using puppet cert list
and puppet cert sign
on the Puppet server.
Puppet classes can be added to host groups in Foreman instead of individual hosts, enabling a standard configuration of many hosts simultaneously. Host groups are typically used to represent server roles.
There are several different methods of installing Foreman. The recommended way is with the puppet based Foreman Installer but you may also use your distribution’s package manager or install directly from source.
This sections outlines the system requirements for an installation of Foreman. This will cover the hardware requirements, OS requirements and firewall requirements. This includes variations for all supported database types.
The following operating systems are supported by the installer, have packages and are tested for deploying Foreman:
PostgreSQL version 10 or newer.
It is recommended to apply all OS updates if possible.
All platforms will require Puppet 6 or higher, which may be installed from Puppet’s repositories.
Other operating systems will need to use alternative installation methods, such as from source.
The following operating systems are known to install successfully from Foreman:
The hardware requirements for Foreman depend primarily on the number of requests that it will receive, which depends on the number of configuration management clients, web UI activity and other systems using the API.
The default installation when including Puppet server will require:
For a bare minimum installation with few clients and no Puppet server, the requirements are:
Foreman integrates with Puppet and Facter in a few places, but generally using a recent, stable version will be fine. The exact versions of Puppet, Puppetserver and Facter that Foreman is compatible with are listed below.
Puppet version | Foreman installer (AIO) | Foreman installer (non-AIO) | Smart Proxy |
---|---|---|---|
0.x-5.x | Not supported | Not supported | Not supported |
6.x | Not supported | Not supported | Deprecated |
7.x | Supported | Untested | Supported |
The Foreman installer has code for both AIO and non-AIO configurations, switching behavior automatically based on the version of Puppet installed (usually during the first run when answers are stored). Only AIO installations are tested.
Puppetserver is the application for serving Puppet agents used by default since Puppet 4. Both Fedora and Debian have not packaged Puppetserver for their non-AIO packages. The Puppetlabs packages must be used.
Foreman is known to be compatible with all Facter 2.x to 4.x releases.
The Foreman installer and packages are generally incompatible with Puppet Enterprise, however with some manual reconfiguration, individual Foreman components such as the smart proxy should work if needed (some further unsupported documentation can be found on the wiki). The installer in particular will conflict with a Puppet Enterprise installation. It is recommended that Foreman is installed using Puppet “open source”.
Using the most recent version of a major browser is highly recommended, as Foreman and the frameworks it uses offer limited support for older versions.
The recommended requirements are as follows for major browsers:
Other browsers may work unpredictably.
Protect your Foreman environment by blocking all unnecessary and unused ports.
Port | Protocol | Required For |
---|---|---|
53 | TCP & UDP | DNS Server |
67, 68 | UDP | DHCP Server |
69 | UDP | TFTP Server |
80, 443 | TCP | * HTTP & HTTPS access to Foreman web UI / provisioning templates - using Apache |
3000 | TCP | HTTP access to Foreman web UI / provisioning templates - using standalone WEBrick service |
5910 - 5930 | TCP | Server VNC Consoles |
5432 | TCP | Separate PostgreSQL database |
8140 | TCP | * Puppet server |
8443 | TCP | Smart Proxy, open only to Foreman |
Ports indicated with * are running by default on a Foreman all-in-one installation and should be open.
The Foreman installer is a collection of Puppet modules that installs everything required for a full working Foreman setup. It uses native OS packaging (e.g. RPM and .deb packages) and adds necessary configuration for the complete installation.
Components include the Foreman web UI, Smart Proxy, and optionally TFTP, DNS and DHCP servers. It is configurable and the Puppet modules can be read or run in “no-op” mode to see what changes it will make.
It’s strongly recommended to use the installer instead of only installing packages, as the installer uses OS packages and it saves a lot of time otherwise spent replicating configuration by hand.
By default it will configure:
Other modules can be enabled, which will also configure:
It’s recommended to run the installer on a fresh and clean single-purpose system, since the configurations of the aforementioned components is (at least partially) overwritten by the installer.
Follow the instructions in section 2.1 Quickstart installation
The installation run is non-interactive, but the configuration can be customized by supplying any of the options listed in foreman-installer --help
, or by running foreman-installer -i
for interactive mode. More examples are given in the Installation Options section. Adding -v
will disable the progress bar and display all changes, while --noop
will run without making any changes. To run the installer, execute:
After it completes, the installer will print some details about where to find Foreman and the Smart Proxy. Output should be similar to this:
The installer is a collection of Puppet modules, which have a large number of parameters available to customize the configuration. Parameters can be set by running foreman-installer
with arguments, e.g. --foreman-initial-admin-password
, changing settings in interactive mode or by setting up an answers file.
The precedence for settings is for those set by arguments to foreman-installer or interactive mode, then the answers file, then the Puppet manifest defaults.
Every parameter available in the installer can be set using command line arguments to foreman-installer
. Run foreman-installer --help
for most options, or foreman-installer --full-help
for a list of every available option.
When running the installer, all arguments passed on the command line will be persisted by default to /etc/foreman-installer/scenarios.d/foreman-answers.yaml
and used automatically on subsequent runs, without needing to specify those arguments again. This persistence can be disabled with the -b
option.
The installer also provides a text driven interface to customize configuration parameters, and can be run by executing:
The installer contains a number of high level modules (e.g. “foreman”, “puppet”) and additionally a number of smaller modules for additional functionality, such as plugins and compute resource support. These can be added with the “–enable” switches, or the default options can be disabled with “–no-enable” switches.
More information about compute resources can be found in the Compute Resources section and plugins in the Plugins section.

The answers file describes the classes that will be applied to the host to
install Foreman, along with their parameters. The foreman-installer package stores it at /etc/foreman-installer/scenarios.d/foreman-answers.yaml
. By default, the all-in-one setup will include Foreman, a puppetmaster, Puppet agent, and the Smart Proxy:
Other examples are given in the next section, or /usr/share/foreman-installer/README.md
.
Additional configuration options can be given in /etc/foreman-installer/custom-hiera.yaml
for some of the Puppet modules that are used internally by Foreman installer. The contents of this file will be passed to Hiera during the Foreman installer execution so can set class parameters for other modules such as apache
, mysql
, and postgresql
.
For example, the TraceEnable
option may be controlled by disabling the apache::trace_enable
parameter in this file:
Please note that the parameters used by these modules may change between versions of Foreman, so it’s important to check the versions in use and the appropriate module documentation or source code when editing this configuration file. Modifications cannot be supported or migrated by Foreman.
The Foreman installer can accommodate more complex, multi-host setups when supplied with appropriate parameters.
Per default foreman-installer will install a PostgreSQL database server onto the Foreman host and create its database. An external database server with an already created database can be used with the following arguments:
As a post-installation step, to populate the database correctly, run:
Using the scenarios outlined below, a simple scale-out setup can be created as follows:
For each additional Smart Proxy:
Note This relies on the puppet ssl subcommand introduced in Puppet 6. Prior to Puppet 6 there was no separate command and it required manual work.
Assuming the Puppetserver with CA is on foreman.example.com
, the following command can be run:
puppet ssl bootstrap --server foreman.example.com
This will submit a CSR (Certificate Signing Request) to the Puppet CA running on foreman.example.com. There the request can be signed.
puppetserver ca sign --certname host.example.com
CSRs also show up in the Foreman interface and can be signed there as well.
A standalone Puppetserver can be configured along with a smart proxy installation, enabling the Puppet infrastructure to be scaled out. This assumes the SSL certificates have been bootstrapped.
Command line arguments:
Fill in the OAuth consumer key and secret values from your Foreman instance, retrieve them from your Foreman server, using: sudo foreman-rake config | grep oauth_consumer
, and set the Foreman URLs appropriately. These allow the smart proxy to register automatically with the Foreman instance, or disable with --foreman-proxy-register-in-foreman=false
.
An existing PuppetDB server can be integrated into a Puppetserver by adding:
Be aware that foreman-installer does not setup the PuppetDB server itself. Only setups using Puppet’s Puppet AIO packages are supported for PuppetDB integration using these parameters.
The default “all-in-one” Foreman installation includes a Puppetserver, but this can be disabled. Foreman by default uses Puppet’s SSL certificates however, so the certificates must be bootstrapped.
Command line arguments:
This will still configure the Puppet agent, but this too can be disabled with --no-enable-puppet
to disable the whole Puppet module.
The smart proxy allows management of various network services, such as DNS, DHCP and TFTP. The installer can set up a basic smart proxy service ready to be configured, or it can install and configure BIND or ISC DHCP ready to go. A certificate should be generated and copied to the host first so Foreman can contact the proxy server.
Command line arguments for a basic smart proxy installation:
Fill in the OAuth consumer key and secret values from your Foreman instance, retrieve them from your Foreman server, using: sudo foreman-rake config | grep oauth_consumer
, and set the Foreman URLs appropriately. These allow the smart proxy to register automatically with the Foreman instance, or disable with --foreman-proxy-register-in-foreman=false
.
Command line arguments for a smart proxy configured with just TFTP, BIND, setting DNS forwarders and overriding the default forward and reverse DNS zones:
Ensure the dns-interface argument is updated with the correct network interface name for the DNS server to listen on. After configuration, make sure to create Subnet in Foreman under Infrastructure > Subnets for the particular Smart Proxy which registers automatically.
Command line arguments for a smart proxy configured with just ISC DHCP and a single DHCP subnet:
Also ensure here that the dhcp-interface argument is updated for the interface to run DHCP on. After configuration, make sure to create a new Subnet (or import from existing) in the Foreman interface.
While it is possible to define the same DHCP range in Foreman, it’s usually good practice to select a range from outside the pool defined in the installer, but still in the subnet. For the example above, it is recommended to define the DHCP range from 10.0.0.1 to 10.0.0.99 in the Foreman UI which gives the following IP address distribution:
Packages are available for Red Hat and Debian-based distributions. This will install a standalone Foreman service running under Puma.
The Puppet-based Foreman installer is recommended for most environments, instead of installing only the packages as it will perform full configuration too.
Foreman is packaged for the following RPM based distributions:
Note: The RPM packages are not tested on Rocky Linux or Oracle Linux. The Foreman installation on Rocky Linux or Oracle Linux may or may not work.
For most users, it’s highly recommended to use the installer as the packages only provide the software and a standalone Foreman service. The installer installs these packages, then additionally configures Foreman to run under Apache with PostgreSQL, plus can configure a complete Puppet setup integrated with Foreman.
It’s recommended to configure the Puppet repositories to obtain the latest version of Puppet available. The version in EPEL is not supported.
Three main repos are provided at https://yum.theforeman.org:
/client
or /client/VERSION
(e.g. /client/3.10
) carries packages relevant to clients. This is optional and Foreman does not require anything installed on clients./releases
or /releases/VERSION
(e.g. /releases/3.10
) carries the all releases and updates of Foreman and its dependencies./plugins
or /plugins/VERSION
(e.g. /plugins/3.10
) carries the all plugin releases.Under each repo are directories for each distribution, then each architecture.
To set up the repository, foreman-release packages are provided which add a repo definition to /etc/yum.repos.d
. Install the release RPM and enable the module:
# EL8
dnf -y install https://yum.theforeman.org/releases/3.10/el8/x86_64/foreman-release.rpm
dnf -y module enable foreman:el8
# EL9
dnf -y install https://yum.theforeman.org/releases/3.10/el9/x86_64/foreman-release.rpm
Release and release candidate packages are signed by the per-release key listed on Security. Nightly packages are not signed.
Install foreman and other foreman-* packages to add functionality:
foreman Foreman server
foreman-proxy Foreman Smart Proxy
foreman-debug Log and debug collection tools
foreman-ec2 Amazon EC2 provisioning support

and /etc/foreman/database.yml
sudo -u foreman /usr/share/foreman/extras/dbmigrate
systemctl start foreman
The Foreman packages should work on the following Debian-based Linux distributions:
If you encounter any errors during the installation, please file a bug report!
Add one of the following lines to your /etc/apt/sources.list (alternatively in a separate file in /etc/apt/sources.list.d/foreman.list):
# Debian Bullseye
deb http://deb.theforeman.org/ bullseye 3.10
# Ubuntu 20.04 Focal
deb http://deb.theforeman.org/ focal 3.10
You may also want some plugins from the plugin repo (required for the Foreman Installer):
deb http://deb.theforeman.org/ plugins 3.10

Foreman Automatic Signing Key (2021) <packages@theforeman.org>
Remember to update your package lists!
apt-get update
The packages are split by gem dependencies - there are 13 packages to choose from. These are:
Main package:
Database gems:
Optional functionality:
Command line interface:
Installation instructions are:
# Install packages (adjust additional packages as needed)
apt-get install foreman foreman-postgresql foreman-libvirt
# Copy sample db config to /etc
cp /usr/share/foreman/config/database.yml.example /etc/foreman/database.yml
# Review settings and DB config
vi /etc/foreman/settings.yaml /etc/foreman/database.yml
# Perform initial DB setup
foreman-rake db:migrate
foreman-rake db:seed
The packages should auto-run db:migrate and db:seed if /etc/foreman/database.yml exists. So the initial DB setup is only needed during first install, upgrades should just work.
Installing the latest development code: Foreman uses Bundler to install dependencies and get up and running. This is the preferred way to get Foreman if you want to benefit from the latest improvements. By using the git repository you can also upgrade more easily. You will need to have Bundler installed manually for now (check your distribution repositories, or install it via rubygems).
Foreman will run with the following requirements (aside from rubygem dependencies):
You will want to make sure that you have postgresql-devel installed so the database gems can install properly. Also, you would also need gcc, ruby-devel, libxml-devel, libxslt-devel, libvirt-devel, nodejs, and npm packages.
For RHEL7 or clones, you can issue the following commands to install all required packages:
yum groupinstall "Development Tools" "Development Libraries"
yum -y install gcc-c++ git ruby ruby-devel rubygems \
libvirt-devel postgresql-devel openssl-devel \
libxml2-devel libxslt-devel zlib-devel \
readline-devel systemd-devel tar nodejs npm libcurl-devel
Additionally, it is important that config/database.yml
is set to use
the correct database in the “production” block. Rails (and subsequently
Foreman) will use these connection settings under “production” to manage
the database it uses and setup the necessary schema.
The db:seed step will print out the default admin password, record this in order to log in later.
In order to run Foreman you can use the following command inside your git repository:
foreman-rake <task>
to run rake tasks, however when installed from source, replace this with bundle exec rake <task> RAILS_ENV=production
to get latest “stable” version do:
To install hammer from git checkouts, you will just need rake
installed on your system.
Clone and install CLI core
and clone plugin with foreman commands
You can install other hammer plugins via any of the methods mentioned above.
The following sections detail the configuration steps required to get Foreman working in your environment. Lets get started!
Foreman configuration is managed from two places; a configuration file config/settings.yaml and from the SETTINGS/Foreman Settings page. A full description of the configuration options is given at foreman_configuration
Foreman requires a database of its own to operate - database sharing is unsupported. PostgreSQL is the only database that is considered supported for production use. The installer can set this up for you.
In all cases, please use the production settings.
to initialize the database schema and content, run:
foreman-rake db:migrate
foreman-rake db:seed
For more information please see the database configuration page here
At this point, you might want to go through the [[FAQ]] to see how can you import your data into Foreman.
if you installed via rpm, just start the foreman service, or start the builtin web server by typing:
RAILS_ENV=production rails server
and point your browser to http://foreman:3000
Read Puppet_Reports to learn how to get your nodes to report to Foreman.
Configuration is broken into two parts. The /etc/foreman/settings.yaml file and the Administer > Settings page. The configuration file contains a few low-level options that need to be set before Foreman starts but the majority of Foreman customization is managed from within the web interface on the Settings page.
The configuration file can also override those settings specified in the web interface. Any settings added in the config file that are available in the web interface will be made read-only.
The first non-comment line of this file must be three dashes.
---
This boolean option configures whether Foreman insists on using only https/ssl encrypted communication channels in the web interface. This does not configure the channels used to contact the smart-proxies. Note that certain operations will still accept a http connection even if this is set, for example, the downloading of a finish script.
:require_ssl: true
This boolean options configures whether Foreman will provide support for the JavaScript object notation with padding. When set to true then Foreman will allow to pass a callback parameter to the API calls.
:support_jsonp: false
This setting configures Rails’ ActionDispatch::RemoteIp middleware. This is for secure handling of the X-Forwarded-For
header that HTTP proxies send. Note that some Foreman Proxy features behave as an HTTP proxy (most notably Templates), but it can also be a classical reverse proxy such as Apache.
This should list the IP addresses or IP ranges that can send the X-Fowarded-For
header. Implicitly this means they can spoof the request IP addresses so only set this if you use a reverse HTTP proxy and on trusted values. Being too broad can introduce security risks.
If you use a reverse proxy in front of Puma (as the installer does by default), be sure to include localhost IPs.
:trusted_proxies:
- 127.0.0.0/8
- ::1
This options contains a hash of parameters that override the current logging configuration. It supports any of the options that are in logging.yaml
(see below), but most usually it’s used to change the log level for debugging.
:logging:
:level: debug
This options contains a hash of config options for specific loggers, which cover parts of Foreman functionality. It’s usually used to enable additional types of logging.
Available loggers are:
Uncomment or add a :loggers block to enable or disable loggers:
:loggers:
:app:
:enabled: true
:ldap:
:enabled: false
:permissions:
:enabled: false
:sql:
:enabled: false
Some plugins may add their own loggers. See the configuration files in /etc/foreman/plugins/ which should list possibilities and enable them there.
This settings file can be found at /etc/foreman/logging.yaml
, or config/logging.yaml
on a source installation. It controls the default logging locations, formatting and log levels per Rails environment.
In a normal installation, only the “production” environment is relevant - development and test are only used in source installations. The file has comments for the most common configuration options, which can be changed here or overridden from the logging
directive in the main settings.yaml
config file (see above).
When enabled, unattended URLs used to fetch templates for individual hosts will be accessible irrespective of the host build state. When disabled, the unattended URLs will only function in build mode to prevent accidental rebuilding etc. Default: false
When Foreman needs to mail the administrator then this is the email address that it will contact. The domain is determined from Facter, else it will default to the “:domain” setting in /etc/foreman/settings.yaml. Default: root@<your domain>.
When reporting the configuration status of hosts, usually only hosts with outdated reports, or a Puppet proxy/master set and no reports will be considered out of sync. When true, all hosts will be considered out of sync until a report is received. This setting should be enabled in environments where Foreman is used for reporting without smart proxies. Default: false
mod_proxy and other load balancers will set a REMOTE_USER environment variable. If this is true , your users will be able to login through an external service and Foreman requests will be authenticated using this REMOTE_USER variable. Default: false
Same as above, but this setting allows REMOTE_USER authentication for API calls as well. Default: false
If you have authorize_login_delegation set, new users can be autocreated through your external authentication mechanism by changing this to the name of the Auth Source you want to use to auto create users. Default: ‘’
By default, all BMC passwords will be redacted in template and ENC output, preventing both users from viewing the passwords directly and also from configuration (or access) in Puppet and other config management tools using the ENC interface. Foreman will continue to use the stored password for BMC power operations.
When set to true, all passwords stored on BMC network interfaces will be visible to other users who can view the host via the ENC YAML preview and accessible through templates, for the purposes of configuring BMC interfaces automatically.
Note that setting this to false also this requires that safemode_render
be enabled, else it could be bypassed.
Default: false
During host provisioning onto a compute resource using images or templates and a finish script, this setting controls the behavior of Foreman when the script fails. When true, the new host and virtual machine (on the compute resource) will be deleted if the script fails. When false, the host and virtual machine are left running so the script can be debugged. Default: true
When facts are received from Puppet or other configuration management systems, a corresponding host will be created in Foreman if the certname or hostname is unknown. When false, this behavior is disabled and facts will be discarded from unknown hosts. Default: true See also: create_new_host_when_report_is_uploaded
If a report is received from Puppet or other configuration management systems, a corresponding host will be created in Foreman if the hostname is unknown. When false, this behavior is disabled and reports will be discarded from unknown hosts. Default: true See also: create_new_host_when_facts_are_uploaded
When you upgrade Foreman using foreman-installer, the new version may contain some seed data such as operating systems, provisioning templates, roles and more. It will also update any previous seeded data. If this is true, the next run of the installer will seed this data. If it is false, the database will not get this seeded data.
Default: true
Specifies, which language is set for newly created users. This also applies to new users managed via LDAP.
Default: ‘’, but ‘Browser language’ is used for newly created users. This also applies to new users managed via LDAP.
Specifies, which timezone is set for newly created users.
Default: ‘’, but ‘Browser timezone’ is used for newly created users.
The name of an location that hosts uploading facts into Foreman will be assigned to if they are new or missing an location. This can be used when hosts are created through fact uploads to ensure they’re assigned to the correct location to prevent resource mismatches. For inherited location, the fact should use slash-delimited names, e.g. “USA/New York”. Default: ‘’, but initialized by the database seed to the initially seeded location
The name of an organization that hosts uploading facts into Foreman will be assigned to if they are new or missing an organization. This can be used when hosts are created through fact uploads to ensure they’re assigned to the correct organization to prevent resource mismatches. For inherited organization, the fact should use slash-delimited names, e.g. “ACME Inc/Engineering”. Default: ‘’, but initialized by the database seed to the initially seeded organization
The method for sending emails from the Foreman instance, either sendmail (running the command set by sendmail_location) to send mail via the configured local MTA, or smtp for direct connection to an outbound SMTP server (given by settings with the smtp prefix). Default: sendmail
The return address applied to outgoing emails. Default: Foreman-noreply@<your domain>
The subject line prefix for any emails sent by Foreman. Default: [foreman]
The number of entries that will be shown in the web interface for list operations. Default: 20
Emails may contain embedded references to Foreman’s web interface. This option allows the URL prefix to be configured. The FQDN is determined from Facter, else it will default to the “:fqdn” setting in /etc/foreman/settings.yaml. Default: https://FQDN/ or http://FQDN/ (depending on require_ssl) See also: unattended_url
Default PXELinux/PXEGrub/PXEGrub2 template. This template gets deployed to all configured TFTP servers. For example, this template can be used to make new hosts in a network boot into Foreman Discovery.
Matchers used in smart variables or smart class parameters to match host groups, organizations or locations can be inherited by children too (e.g. a matcher for hostgroup=Base will also apply to Base/Web). Set this to false to make matchers only match a particular hostgroup, organization or location and not its children. Default: true
Controls whether the power status of hosts is shown on the hosts list, which may lead to decreased performance, or if the column is removed. Default: true
Defines which is the default owner of newly provisioned hosts. It can be either a user or a user group. If unset, the default owner of the host will be the user who created the host. Default: none
Users that stay idle (no requests sent to Foreman) for more than this number of minutes will be logged out. Default: 60
If true, Foreman variables will be exposed to the ENC. Check Template Writing Reference for a more comprehensive guide on how to create and use these variables in your ERB templates. Default: true
When Foreman receives facts for a host (from any source, Puppet, Ansible…) it will try to update the operating system to whatever the incoming facts say. This setting allows you to import all facts but ignore those related with operating system. If this is set to true, Foreman will update the operating system of hosts using these facts. Default: false See also: ignored_facts_for_domain
See ignored_facts_for_operatingsystem - this setting is the equivalent for domains. Default: false
If this option is set to true then Foreman will not update the IP and MAC addresses stored on a host’s network interfaces with the values that it receives from facts. It will also include Foreman’s values for IP and MAC to Puppet in its node/ENC information. Default: false See also: ignored_interface_identifiers
When importing facts and updating stored information on network interfaces, any network interface with an identifier (e.g. eth0
) that matches any of the items in this list will be ignored and not updated. This can be used to avoid updating special types of interfaces when Foreman has limited or no understanding of them. The contents are an array of strings which may contain *
wildcards to match zero or more characters.
Default: ["lo", "en*v*", "usb*", "vnet*", "macvtap*", ";vdsmdummy;", "veth*", "docker*", "tap*", "qbr*", "qvb*", "qvo*", "qr-*", "qg-*", "vlinuxbr*", "vovsbr*", "br-int", "vif*", "cali*"]
See also: ignore_puppet_facts_for_provisioning
The IP address that should be used for the console listen address when provisioning new virtual machines via Libvirt. Default: 0.0.0.0
The name of a fact from hosts reporting into Foreman which gives the full location name of the host. This can be used when hosts are created through fact uploads to ensure they’re assigned to the correct location to prevent resource mismatches. The location of a host will be updated to the value of the fact on every fact upload. For inherited locations, the fact should use slash-delimited names, e.g. “USA/New York”. Default: foreman_location
When creating hosts that use a PXE loader, this will be the default template for local boot.
If your external authentication system has a logout URL, redirect your users to it here. This setting can be useful if your users sign in Foreman through SSO, and you want them to sign out from all services when they log out Foreman. Default: ‘’
Text to be displayted in the login-page footer. The keyword $VERSION
is replaced by the current version.
Default: Version $VERSION
If this option is set to true then Foreman will manage a host’s Puppet certificate signing. If it is set to false then some external mechanism is required to ensure that the host’s certificate request is signed. Default: true
Specifies the method used to generate random hostnames when creating a new host, either Random-based, MAC-based for bare metal hosts only, or Off to disable the function and leave the field blank. Default: Random-based
Enables OAuth authentication for API requests. Default: false
OAuth consumer key Default: none
OAuth consumer secret Default: none
This allows OAuth users to specify which user their requests map to. When this is false, OAuth requests will map to admin. Default: true
The name of a fact from hosts reporting into Foreman which gives the full organization name of the host. This can be used when hosts are created through fact uploads to ensure they’re assigned to the correct organization to prevent resource mismatches. The organization of a host will be updated to the value of the fact on every fact upload. For inherited organization, the fact should use slash-delimited names, e.g. “ACME Inc/Engineering”. Default: foreman_organization
Duration in minutes after which servers classed as out of sync, if the report origin has not been identified. Default: 30
Timeout in seconds used when making REST requests to a Smart Proxy, e.g. when importing Puppet classes or creating DHCP records. May be set to a larger value when certain operations take a long time. Default: 60
If true, Foreman will query the local DNS. When false Foreman will query the SOA/NS authority. Warning! Querying a resolver can cause Foreman to get false positives when checking presence of DNS records due to caching. Default: false See also: dns_conflict_timeout
When set to true, services such as Puppet servers (or Salt) need to have a smart proxy registered with the appropriate feature (e.g. Puppet) to access fact/report importers and ENC output. Default: true
If a root password is not provided whilst configuring a host or its host group then this encrypted password is used when building the host. Default: ‘’ (To generate a new one you should use: openssl passwd -1 “your_password” )
In the default configuration with safemode_render
set to true, access to variables, Foreman internals and any object that is not whitelisted within Foreman will be denied for system security.
When set to false, any object may be accessed by a user with permission to use templating features, either via editing of templates, parameters or smart variables. This permits users full remote code execution on the Foreman server, effectively disabling all authorization if set to false. It is strongly recommended for this setting to be true in most environments.
Default: true
New account holders will receive a welcome email when the account is created if this is enabled, including their username and a link to Foreman. Default: false
Arguments given to the sendmail command when sending emails from Foreman.
Default: -i
Path to the sendmail binary, or other sendmail-compatible MTA for outbound email.
Default: /usr/sbin/sendmail
Outbound SMTP connections will connect to the SMTP server at this address, either a hostname or IP address. Default: empty value (implying localhost)
Outbound SMTP connections will authenticate to the SMTP server using the protocol specified here, either: plain for the PLAIN SMTP mechanism (plain text), login for the LOGIN SMTP mechanism (plain text), cram-md5 for the CRAM-MD5 method (hashed, not plain text), or none to disable authentication. See also: smtp_username, smtp_password. Default: none
Outbound SMTP connections will use this domain to identify during the HELO/EHLO command. Default: empty value
Outbound SMTP connections will automatically switch to TLS mode (via STARTTLS
) when the capability is advertised by the SMTP server. This implies verification of TLS/SSL certificates by default (see also: smtp_openssl_verify_mode).
Default: true
Outbound SMTP connections to a TLS-enabled SMTP server will verify the remote server certificate according to this setting. Either the default (usually peer), none for no verification of the server certificate, or peer for explicitly verifying the server certificate. client_once and fail_if_no_peer_cert have no effect in outbound SMTP connections. Default: Default verification mode (usually peer)
Outbound SMTP connections with authentication enabled will authenticate with this password (see also: smtp_username, smtp_authentication). Default: empty value
Outbound SMTP connections will connect to the SMTP server on this TCP port. Some SMTP servers may prefer port 587 for email submission. Default: 25
Outbound SMTP connections with authentication enabled will identify with this username (see also: smtp_password, smtp_authentication). Default: empty value
Environment variable containing the entire PEM-encoded certificate from the client. This environment variable is required when authenticating using Subject Alternative Names and will be preferred over ssl_client_dn_env
if available. Under Apache HTTP and mod_ssl, SSLOptions +ExportCertData
sets this environment variable.
Default: SSL_CLIENT_CERT
See also: ssl_client_dn_env
Environment variable containing the subject DN from a client SSL certificate. Under Apache HTTP and mod_ssl, SSLOptions +StdEnvVars
sets this environment variable.
Default: SSL_CLIENT_S_DN
See also: ssl_client_cert_env
Environment variable containing the verification status of a client SSL certificate Default: SSL_CLIENT_VERIFY
The SSL Certificate Authority file that Foreman will use when connecting to its smart-proxies. Default: The CA file used by puppet
The SSL certificate that Foreman will use when connecting to its smart-proxies. Default: The host certificate used by puppet
The SSL private key file that Foreman will use when connecting to its smart-proxies. Default: The private key file used by puppet
Time in minutes installation tokens should be valid for, 0 to disable token generation. Default: 360 (6 hours)
Other trusted hosts in addition to Smart Proxies allowed to access fact/report importers and ENC output. i.e: [puppetserver1.yourdomain.com, puppetserver2.yourdomain.com] Default: []
This controls the URL prefix used in provisioning templates such as TFTP/PXELinux files that refer to the Foreman server. It is usually HTTP rather than HTTPS due to lack of installer support for HTTPS. The FQDN is determined from Facter, else it will default to the “:fqdn” setting in /etc/foreman/settings.yaml. Default: http://FQDN/ See also: foreman_url
If Foreman receives an environment fact from one of its hosts and if this option is true, it will update the host’s environment with the new value. By default this is not the case as Foreman should manage the host’s environment. Default: false
If true, Foreman will update the host IP with the IP that made the ‘build’ request. This request is made at the end of a provisioning cycle to indicate a host has completed the build. Default: false
If true, fact imports from Puppet and other config management tools will update the subnet on host network interfaces to match the IP address given in facts, preventing a mismatch. Default: false
When false, any hosts created on a compute resource will use the FQDN of the host for the name of the virtual machine. When set to the true, the short name (i.e. without domain) will be used instead. Default: false
When enabled, Foreman will generate UUIDs for each host instead of using the hostname as the Puppet certname, which is more reliable with changing hostnames. Note that when disabling this setting, existing stored certnames won’t be changed or discarded until new certificates are requested from a host (i.e. on a rebuild), in order that the existing certificate remains known to Foreman and can be revoked.
When enabled, virtual machine consoles using NoVNC will always be sent over an encrypted WebSocket connection. Requires both websockets_ssl_cert
and websockets_ssl_key
to be configured too.
Default: true if require_ssl
is enabled
See also: websockets_ssl_cert, websockets_ssl_key
Path to the SSL certificate that will be used for the WebSockets server when serving virtual machine consoles. Should be the same as the SSL certificate used for the Foreman web server (e.g. Apache).
Path to the SSL private key that will be used for the WebSockets server when serving virtual machine consoles. Should be the same as the SSL key used for the Foreman web server (e.g. Apache).
Foreman is a Rails application. While Rails supports different databases, Foreman supports only PostgreSQL for production deployments.
The database configuration file can be found at:
/etc/foreman/database.yml
Edit your config/database.yml and modify:
production:
adapter: postgresql
database: foreman
username: foreman
password: password
host: localhost
Foreman uses a custom puppet reports address (similar to tagmail or store) which Puppet will use to upload its report into Foreman. This enables you to see the reports through the web interface as soon as the client finishes its run.
Ensure that the puppet clients has the following option in their puppet.conf:
report = true
Without it, no reports will be sent.
First identify the directory containing report processors, e.g.
locate tagmail.rb
)Copy the report processor source to this report directory and name it foreman.rb
.
Create a new configuration file at /etc/puppetlabs/puppet/foreman.yaml
(Puppet 4 AIO) or /etc/puppet/foreman.yaml
(non-AIO) containing:
---
# Update for your Foreman and Puppet server hostname(s)
:url: "https://foreman.example.com"
:ssl_ca: "/etc/puppetlabs/puppet/ssl/certs/ca.pem"
:ssl_cert: "/etc/puppetlabs/puppet/ssl/certs/puppet.example.com.pem"
:ssl_key: "/etc/puppetlabs/puppet/ssl/private_keys/puppet.example.com.pem"
# Advanced settings
:puppetdir: "/opt/puppetlabs/server/data/puppetserver"
:puppetuser: "puppet"
:facts: true
:timeout: 10
:threads: null
Edit the URL field to point to your Foreman instance, and the SSL fields for the hostname of the Puppet server (which may be the same host). Paths to Puppet’s SSL certificates will be under /var/lib/puppet/ssl/ when using Puppet with non-AIO.
Lastly add this report processor to your Puppet server configuration. In your server puppet.conf under the [main]
section add:
reports=log, foreman
and restart your Puppet server.
You should start seeing reports coming in under the reports link.
If reports aren’t showing up in Foreman when an agent is run, there can be a number of reasons. First check through the above configuration steps, and then look at these places to narrow down the cause:
puppetserver
messages, or /var/log/puppetlabs/puppetserver/.POST "/api/reports"
request each time a report is received, and will end in Completed 201 Created
when successful. Check for errors within the block of log messages.You will probably want to delete your reports after some time to limit database growth. To do so, you can set a cronjob:
Available conditions:
To expires all reports regardless of their status:
foreman-rake reports:expire days=7
To expire all non-interesting reports after one day:
foreman-rake reports:expire days=1 status=0
Foreman can act as a classifier to Puppet through the External Nodes interface. This is a mechanism provided by Puppet to ask for configuration data from an external service, via a script on the Puppet server.
The external nodes script we supply also deals with uploading facts from hosts to Foreman, so we will discuss the two things together.
Download the ENC script to /etc/puppetlabs/puppet/node.rb
(Puppet AIO) or /etc/puppet/node.rb
(non-AIO). The name is arbitrary, but must match configuration below, and ensure it’s executable by “puppet” with chmod +x /etc/puppet/node.rb
.
Unless it already exists from setting up reporting, create a new configuration file at /etc/puppetlabs/puppet/foreman.yaml
(Puppet AIO) or /etc/puppet/foreman.yaml
(non-AIO) containing
---
# Update for your Foreman and Puppet server hostname(s)
:url: "https://foreman.example.com"
:ssl_ca: "/etc/puppetlabs/puppet/ssl/certs/ca.pem"
:ssl_cert: "/etc/puppetlabs/puppet/ssl/certs/puppet.example.com.pem"
:ssl_key: "/etc/puppetlabs/puppet/ssl/private_keys/puppet.example.com.pem"
# Advanced settings
:puppetdir: "/opt/puppetlabs/server/data/puppetserver"
:puppetuser: "puppet"
:facts: true
:timeout: 10
:threads: null
Edit the URL field to point to your Foreman instance, and the SSL fields for the hostname of the Puppet server (which may be the same host). Paths to Puppet’s SSL certificates will be under /var/lib/puppet/ssl/ and puppetdir will be under /var/lib/puppet when using Puppet with non-AIO. More information on SSL certificates is at Securing communications with SSL.
Add the following lines to the [master] section of puppet.conf:
[master]
external_nodes = /etc/puppetlabs/puppet/node.rb
node_terminus = exec
Restart the Puppet server. When the next agent checks in, the script will upload fact data for this host to Foreman, and download the ENC data.
The --no-environment
option can be optionally specified to stop the ENC from
being authoritative about the agent’s Puppet environment. This can be useful
in development setups where the agent may be run against different
environments.
No agent configuration is necessary to use this functionality.
Make sure that the puppet user can execute the ENC script and it works:
sudo -u puppet /etc/puppet/node.rb [the name of a node, eg agent.local]
should output something like:
parameters:
puppetmaster: puppet
foreman_env: &id001 production
classes:
helloworld:
environment: *id001
This output should match the information displayed when you click on the YAML button on the Host page in Foreman.
For further information see the Puppet Labs docs on external nodes
POST "/api/hosts/facts"
and GET "/node/client.example.com?format=yml"
and for any errors within the block of log messages.Foreman passes all associated parameters, classes,and class parameters, to the Host, including those inherited from host groups, domains, or global settings. See section Managing Puppet for more information on assigning configuration to hosts.
By default, Foreman adds hosts to its database that it learns about through facts, provided the “create_new_host_when_facts_are_uploaded” setting is enabled.
Locations and organizations can be inferred from the “foreman_location” or “foreman_organization” facts as supplied by the host. The names of these facts can be changed with the “location_fact” and “organization_fact” settings respectively. Foreman will update hosts on each fact upload based on the value of these facts.
If these facts aren’t supplied, then the “default_location” and “default_organization” settings can be used to set values globally when a host doesn’t have a location or an organization set.
More information in the Configuration section.
There are several options for pushing fact data to Foreman if you are using Foreman for reporting/inventory only.
The ENC script (node.rb) accepts an option to run in ‘batch-mode’. In this mode, the script iterates over the cached fact data stored on the Puppet server, and uploads all of it to Foreman.
Download and configure the node.rb script as above, and then call it like this:
sudo -u puppet /etc/puppetlabs/puppet/node.rb --push-facts
The following options are available for node.rb’s batch mode:
--push-facts
uploads all facts sequentially which have changed since the
last run.--push-facts-parallel
uploads all facts in parallel which have changed since
the last run. The number of threads is specified by the :threads setting or
the number of processors.--watch-facts
runs in the foreground and upload facts based on inotify
events, used in conjunction with either –push-facts option.Foreman’s fact-upload API endpoint accepts data in pure JSON. You can push data to Foreman as a hash containing:
{
"name": "fqdn-of-host.domain.com",
"certname": "optional-certname-of-host.domain.com",
"facts": {
"fact1": "string",
"fact2": "true",
"fact3": "1.2.3.4",
...
}
}
The ‘certname’ is optional but will be used to locate the Host in Foreman when supplied. See the API documentation for more details.
This body can be POSTed to ‘/api/hosts/facts’ using Foreman API v2. See the node.rb template for an example of constructing and sending data in Ruby.
The Command Line Interface is based on the hammer framework. The foreman-related commands are defined in plugin hammer_cli_foreman
Configuration is loaded from a set of directories in this order:
./config/hammer/
(config dir in CWD)/etc/hammer/
.~/.hammer/
-c CONF_FILE_PATH
In each of these directories hammer tries to load cli_config.yml
and anything in the cli.modules.d
subdirectory which is the recommended location for configuration of hammer modules.
Later directories and files have precedence if they redefine the same option. Files from cli.modules.d are loaded in alphabetical order.
Hammer uses yaml formatting for its configuration. The config file template is contained in the hammer_cli gem.
gem contents hammer_cli|grep cli_config.template.yml
and can be copied to one of the locations above and changed as needed. The packaged version of hammer copies the template to /etc for you.
Plugins are disabled by default. You have to edit the config file and enable them manually under modules
option, as can be seen in the sample config below.
Plugin specific configuration should be nested under plugin’s name.
:log_dir: <path>
- directory where the logs are stored. The default is /var/log/hammer/
and the log file is named hammer.log
:log_level: <level>
- logging level. One of debug
, info
, warning
, error
, fatal
:log_owner: <owner>
- logfile owner:log_group: <group>
- logfile group:log_size: 1048576
- size in bytes, when exceeded the log rotates. Default is 1MB:watch_plain: false
- turn on/off syntax highlighting of data being logged in debug mode:modules:

:password: 'changeme'
:log_dir: '/var/log/foreman/'
:log_level: 'debug'
These instructions apply to environments not using Katello
If you’re using the Katello content management plugin scenario, please follow their upgrade instructions (which will also upgrade Foreman).
Before updating to 3.10, make sure you have successfully upgraded to 3.9 first.
Upgrading across more than one version is not supported, so it’s required to upgrade to each intermediate version and follow all upgrade instructions for the previous versions.
Check the list of Supported Platforms when planning to upgrade, as these change between releases. If your OS is no longer supported by Foreman, migrate or upgrade the OS (if supported) using a release of Foreman supported by both OS versions before upgrading Foreman.
To provide specific installation instructions, please select your operating system:
It is recommended that you backup your database and modifications to Foreman files(config/settings.yaml, unattended installations etc). Most upgrades are safe but it never hurts to have a backup just in case.
For more information about how to backup your instance head over to Backup
Before proceeding, it is necessary to shutdown the Foreman instance.
Now it’s time to perform the actual upgrade.
Make sure by executing database is migrated. It should produce no errors or output:
foreman-rake db:migrate
foreman-rake db:seed
You should clear the cache and the existing sessions:
foreman-rake tmp:cache:clear
foreman-rake db:sessions:clear
After database migrations, some space can sometimes be reclaimed. It’s a good idea to perform a full database vacuum for PostgreSQL rather than relying on the autovacuum feature to claim maximum space possible.
su - postgres -c 'vacuumdb --full --dbname=foreman'
If you used foreman-installer to set up your existing Foreman instance we recommend running it again after upgrading. Note that the installer can modify config files so this may overwrite your custom changes. You can run the installer in noop mode so you can see what would be changed.
To see what would happen
foreman-installer --noop --verbose
You may see ERRORS such as /Stage[main]/Foreman_proxy::Register/Foreman_smartproxy[foreman-hostname.domain]:
Could not evaluate: Connection refused - connect(2)
due to httpd / apache2 service being stopped. These can be safely ignored.
To apply these changes, run the installer again without options
foreman-installer
Start the application server. This is redundant if you previously ran foreman-installer
in step 3B.
This section covers general information on using Foreman to manage your infrastructure. It covers the features of the web interface, managing puppet, provisioning systems and the installation and configuration of Foreman Smart Proxies.
Foreman natively supports LDAP authentication using one or multiple LDAP directories.
Go to Administer > LDAP Authentication, click on New LDAP Source and enter the following details about the LDAP server:
ldap.example.com
Under the account tab, the details of an account used to read LDAP entries is required if anonymous binds and reads are disabled. This should be a dedicated service account with bind, read and search permissions on the user and group entries in the directory server.
This may use the variable $login
which will be replaced by the login of the authenticating user, however this is deprecated and will result in reduced functionality (as it only works at authentication time).
dc=example,dc=com
ou=Groups,dc=example,dc=com
(memberOf=cn=foreman-users,ou=Groups,dc=example,dc=com)
. Multiple filters can be combined using the syntax (& (filter1) (filter2))
.When configuring an LDAPS connection, the certificate authority needs to be trusted. When using Active Directory Certificate Services, ensure to export the Enterprise PKI CA Certificate using the Base-64 encoded X.509 format.
If your LDAP server uses a certificate chain with intermediate CAs, all of the root and intermediate certificates in the chain must be trusted.
On Red Hat based OSes:
On Debian or Ubuntu, also ensure the file has a .crt extension:
By checking Automatically create accounts in Foreman, any LDAP user will have their Foreman account automatically created the first time they log into Foreman.
You can assign multiple organizations/locations to your LDAP authentication sources. This will assign users that are automatically created to the set of organizations/locations associated with the LDAP authentication source. Please notice this assignment happens only when users are created automatically via LDAP, and not upon every login.
Changing the organization/location of a LDAP authentication source will not automatically change these attributes on the users in that authentication source.
To use this feature, the relevant LDAP attributes must be specified on the next tab (e.g. firstname, lastname, email), as these will be used to populate the Foreman account.
Foreman needs to know how to map internal user account attributes to their LDAP counterparts, such as login, name, and e-mail. Examples for common directory servers are provided below.
Note that LDAP attribute names are case sensitive.
Foreman also has the ability to use a user’s photo stored in LDAP as their Foreman avatar, by setting the jpegPhoto attribute mapping.
Additional Information:
All of the examples below use a dedicated service account called ‘foreman’. This should be set up with bind, read and search permissions on the user and group entries and with a strong, random password.
Typically either LDAPS on port 636 or LDAP on port 389.
Setting | Value |
---|---|
Account | DOMAIN\foreman |
Base DN | CN=Users,DC=example,DC=COM |
Groups base DN | CN=Users,DC=example,DC=com |
Login name attribute | userPrincipalName |
First name attribute | givenName |
Surname attribute | sn |
Email address attribute | mail |
Note that previously we recommended using sAMAccountName as the login name attribute. It turned out that userPrincipalName is a better choice since it does not contain white spaces that can cause issues on user creation.
Typically either LDAPS on port 636 or LDAP on port 389.
Setting | Value |
---|---|
Account | uid=foreman,cn=users,cn=accounts,dc=example,dc=com |
Base DN | cn=users,cn=accounts,dc=example,dc=com |
Groups base DN | cn=groups,cn=accounts,dc=example,dc=com or cn=ng,cn=compat,dc=example,dc=com if you use netgroups |
Login name attribute | uid |
First name attribute | givenName |
Surname attribute | sn |
Email address attribute | mail |
Typically LDAP on port 389 and with anonymous queries (leave Account blank), unless configured otherwise.
Setting | Value |
---|---|
Account | uid=foreman,dc=example,dc=com |
Base DN | dc=example,dc=com |
Groups base DN | dc=example,dc=com |
Login name attribute | uid |
First name attribute | givenName |
Surname attribute | sn |
Email address attribute | mail |
A Foreman user group can be associated to a group stored in an LDAP server, so membership of the LDAP group automatically adds a user to the Foreman user group. User groups can be associated with roles, enabling users to log into Foreman and be automatically granted permissions via their membership of an LDAP group. Read more about permissions in the Roles and Permissions section.
To configure the association, create or edit a user group via Administer > User groups. The group name may be any value (no direct relation to the LDAP group). Under the Roles tab, select roles granting permissions to Foreman, or tick the Admin checkbox to enable administrator level access.
On the External groups tab, click the Add external user group button to open a new form. In the Name field, enter the exact name of the LDAP group (usually the common name/CN) and select the server from the dropdown list of LDAP authentication sources. Click the Submit button to save changes.
When a user logs in for the first time (assuming on the fly account creation), the ldap:refresh_usergroups cronjob runs (every 30 minutes by default) or the Refresh button is pressed next to the external user group entry, Foreman will synchronize the group membership from LDAP.
Please remember your external user groups will only be refreshed automatically through the ldap:refresh_usergroups cronjob. There can be a lapse of time cronjob runs, in which if the user groups in LDAP change, the user will be assigned to the wrong external user groups. This situation can be quickly fixed by manually running foreman-rake ldap:refresh_usergroups
or by refreshing the external user groups in the UI. Otherwise, the problem will eventually get fixed when the cronjob runs again.
When using Active Directory, please be aware that users will be able to log in for up to an hour after a password change using the old password. This is a function of the AD domain controller and not Foreman.
To change this password expiry period, see Microsoft KB906305 for the necessary registry change.
Foreman allows only 30 failed attempts in the last 5 minutes per one IP address by default. Any subsequent login attempts are not allowed and error message is shown: “Too many tries, please try again in a few minutes.” If this is triggered by accident, the silent period can be removed by deleting failed login cache entries:
find /usr/share/foreman/tmp/cache -name failed_login\*
This will only work when using the file store Rails cache implementation.
If you want to use on the fly user creation, make sure that Foreman can fetch from your LDAP all the required information to create a valid user. For example, on-the-fly user creation won’t work if you don’t have valid email addresses in your directory (you will get an ‘Invalid username/password’ error message when trying to log in).
A user’s access to the features of Foreman are constrained by the permissions that they are granted. These permissions are also used to restrict the set of hosts, host groups and other resources that a user is able to access and modify.
Note: a user with global admin enabled is not restricted by the authorization system. This is the default for installations that do not have :login:true in config/settings.yml.
A logged in user will be granted the Default role role plus one or more additional roles. The permissions and filters associated with these roles are aggregated and determine the final permission set.
Roles may be administered by users with admin privileges or regular users with ‘edit_roles’ permission. In order to add new filters and permissions to a role, regular users must have the ‘create_filters’ permission.
These may be created, deleted and edited on the Roles page. Each role will contain permission filters, which define the actions allowed in a certain resource. Once your role is created, you can associate it with one or more users and user groups.
There is one built-in system role, ‘Default role’. This is a set of permissions that every user will be granted, in addition to any other roles that they have. Foreman provides you with a set of seeded roles. These roles can be assigned to users but cannot be modified in any way. They serve as a sane set of defaults and a quick starting point. If you wish to base your custom role on one of these, you can clone it and modify the clone.
Roles can be also associated to Locations or Organizations if these are allowed. Unlike other objects this does not mean that Roles would be only available in a particular scope. Roles are always global for the entirety of Foreman. The association means that filters of such role are scoped to a particular Organization or Location. Imagine you want to create a role representing Administrator of Organization A. You can clone an existing Organization admin role and associate it with Organization A. If you later assign this role to some users, they will be granted all admin permissions but only on resources of Organization A. Note that some resources are not scopeable by Organization and Locations. Filters for such resources grant permissions globally.
The seeded Organization admin role is similar to the Manager role. They are both being automatically extended with permissions introduced in new Foreman versions, as well as permissions introduced by plugins. The difference is that Organization admin role does not contain permissions for managing organizations, only for viewing them. Since organization administrator does not usually need to create or modify other organizations, the Organization admin role fits better this scenario.
System admin role is a seeded role with very powerful abilities. The purpose of this role is to set up environment for others to use. It can create organizations/locations but does not have access to the resources inside them. System admin can create new users and assign them to locations/organizations and add roles to the users. System admin can view and edit settings. But most importantly, users with this role can even delegate roles that they themselves do not own. Users having this role can potentially step out of it by creating a new user with roles/permissions that they do not have as System admin and log in as the newly created user. Therefore only trusted users should be allowed to have this role.
Filters are defined within the context of a role, clicking on the ‘filters and permissions’ link. A filter allows a user to choose a resource (Hosts, Host groups, etc…) and the permissions that should be granted for that resource. After a filter has been created, users given a role containing this filter will have the permissions for the resource specified at the filter.
If the filter is marked as ‘Unlimited?’, the permissions created in this filter will apply to all objects in the chosen resource. For instance, if the resource is Host, and the permissions are ‘view’ and ‘index’, and ‘Unlimited?’ is checked, users that have a role with this filter will be able to ‘view’ and ‘index’ all hosts in the system.
When ‘Unlimited?’ is unchecked, a text box allowing to define more granular filtering will be enabled. You can write a search query and permissions in this filter will be applied to the results of that query only. An example of a query for the resource Host could be ‘os = RedHat’. In this case, the permissions in this filter will be applied only to Hosts whose Operating System is set to Red Hat. You can test your search queries at the index page of your resource, in this case that would be ‘/hosts’.
Some example queries for the resource Host:
Ownership and domain membership: ‘owner_id = 95 and domain = localdomain’ - Will apply permissions to hosts owned by User with id 95 and in the domain ‘localdomain’
Compute resource membership: ‘compute_resource = Openstack’ - Will apply permissions to hosts deployed on compute resource Openstack.
Fact filtering: ‘facts.alarmlevel = high’ - Will apply permissions to hosts with a fact ‘alarmlevel’ with value ‘high’. As a fact is only generated during a puppet run, this filter will only refer to machines that have been built and therefore cannot be used to restrict the creation of machines.
These pools of queries can be combined by adding them together or the filters can be used to restrict the selected resource to a smaller and smaller subset of the total. Think of them as set operations.
As already mentioned, a Role can be assigned to Organizations and Locations. In such case, all filters for resources that support such scoping automatically apply the same Organizations and Locations. If you want to combine filters with different Organizations or Locations assignments, you can use ‘Override’ check box. When checked you can override Organizations and Location for a filter. If you uncheck this field, the filter starts inheriting its role Organizations and Locations after submitting again. If you want to reset all role filters to start inheriting, you can use ‘Disable all filters overriding’ button on role’s ‘Filters’ tab.
We recommend managing Organizations and Locations association on Role level to keep the setup simple and clear.
Note: If the “Administrator” check box is checked for a user, filtering will not take effect.
These determine the operations that are allowed to be performed upon the resources to which they refer. For a few simple items like bookmarks, this operates as expected - it grants permission for all bookmarks. But for most resources, such as the hosts a user is able to operate on, there is an additional layer of security called filtering.
When editing a filter there is a search field at the bottom that narrows the scope of the permissions granted to a subset of the resource objects. Most permission types support this search field however there are some exceptions. The permission for creating objects can’t be limited by a search query because the object does not exist during creation. Therefore a user is granted the create permission if they are associated with any filter containing this permission (limited by search or not).
Following table lists some of permissions and their impact:
Permission | Description |
---|---|
Permissions for Architectures, Authentication providers, environments, External variables, Common parameters, Medias, Models, Operating systems, Partition tables, Puppet classes and User groups | |

Trends and statistics are moved to the separate plugin. See manual for the reference.
There is a rake task foreman-rake purge:trends
for users who are not planning to use trends and statistics anymore and wish to clean up database.
Foreman supports auditing of almost all changes that happen within Foreman, from both the UI and from the API. Auditing is done at a user level, and is thus ineffective if :login: is set to false, as all audits will be done as the ‘admin’ user.
Go to the Audit tab to see a view of what has changed. This view can be filtered by the type of change or by the object that was altered (e.g. search for a hostname to see all changes relating to that host). You also get the parent object - so if a parameter was modified, you can see what host/group that parameter belongs to. The timestamp of the change and the user who performed it will be listed.
Template changes also store a diff of the changes, and the ability to roll back to a previous version of the template.
You will probably want to delete your old audits after some time. To achieve this, there is a cronjob. This job invokes
rake task audits:expire
. There is no default value for number of days to keep because every user has different needs.
However, you can configure an amount of days to keep in Foreman in Settings (Administer -> Settings -> General (Tab) -> Save audits interval
) to fit to your needs. You can leave value empty to no expire old audits. Also this task can be invoked manually whenever required. Invocation can be done by foreman rake audits:expire
. If the days
parameter is not provided, the task is trying to take configured value from Settings
. If this value is also empty, task is closed and no audits are expired.
Available parameters:
Examples:
foreman-rake audits:expire days=7
Here, anonymization clears links to user accounts and their IP addresses, but keeps all other audit data in database.
You can anonymize your old audits instead of deleting the audit entries.
Use task foreman-rake audits:anonymize
for this similarly to audits:expire
.
Example:
foreman-rake audits:anonymize days=7
Audits inherit organizations and locations of resources for which they have been created. Imagine you have a subnet assigned to organization A. Whenever you modify this subnet, the audit will be visible only in organization A. When you later add this subnet to organization B, new audits will appear in both organizations A and B. All audits created previously remain untouched. Resources that can’t be assigned to any organization or location will be always visible in all organizations and locations, meaning the change has affected all organizations and locations.
Audited resources can change in time, e.g. they have new attributes. Also audit definitions changes, e.g. new association starts to be tracked in new version of Foreman. All these changes only apply to newly created audits, old audits can’t be updated and will always contain only data known back in time they were created. Starting with Foreman 1.20, audits are scoped to organizations and locations. All audits created before are unassigned, meaning only admin can see them.
Each page in Foreman has its own search functionality, which is centred around the resources that it manages, allowing searching based on attributes of the resources in the list or resources that they’re associated to. The search box also features powerful auto-completion to help build up search queries and free text search on many pages. The search functionality can also be used in the API when listing resources, see Customize JSON Responses for details.
Searching is through “field = value” or free text queries, which can be combined with logical operators (and, or, not) and parentheses to handle more complex logic. To give some examples:
name = client.example.com
on the host list would show the host(s) whose hostname is client.example.comhostgroup = "Web servers" and domain != lon.example.com
would show hosts in the Web servers host group, but not in the lon.example.com domainWeb servers
would show all hosts with that text anywhere, e.g. as their host group name or in the comment fieldThe fields available depend on the type of resource that’s being searched, and the names of the attributes vary depending on the context. The “name” field on the host groups list is equivalent to the “hostgroup” field on the hosts list. Requests to add additional searchable fields are welcome, and may be filed in the “Search” category in the bug tracker.
The search engine is provided by the scoped_search library, which maps search queries directly to SQL queries. The Query Language documentation provides A more complete specification of the syntax available.
Foreman supports the ability to make search bookmarks, allows users to quickly jump to predefined search conditions. Available bookmarks can be selected from the dropdown menu to the right of the search box, or managed from Administer > Bookmarks.
Some of the bookmarks are provided by default, e.g. to search for active or inactive hosts, or to only view reports with events.
To save a query, Use the dropdown menu to the right of the search box and click “Bookmark this search”. When saving, the bookmark can be labeled as public, so all other users are able to see and use it too.
If you ignore the auto-completer and just enter text in the search field, Foreman will try searching for that text across multiple fields.
For example, if you just enter 12
in the hosts search box, the results will include all hosts with 12 in their IP address, MAC address or name. In general the fields used for free text search are kept to a minimum for performance and accuracy reasons. It’s preferable to search using a specific field, e.g. when searching for an IP address, use ip ~ 12
instead of 12
.
The “has” operator matches values that are present, e.g. to search for hosts that are on a compute resource, use has compute_resource
.
Similarly, this can be negated, so to search for hosts without host groups, you can use not has hostgroup
.
When querying using =
and !=
operators then exact, case sensitive matches will be returned. When running ~
(like) and !~
(unlike) operators, the matching is case insensitive.
In search queries, white spaces are used as a delimiter. Here are some examples of the way a query will be interpreted:
description ~ "created successfully"
: list all notifications that contain “created successfully”description ~ created successfully
: list all notifications that contain “created” and at least one of its text fields contains “successfully”description !~ created successfully
: list all notifications that doesn’t contain “created” and at least one of its text fields contains “successfully”In the second and third example, “successfully” is an additional term that is interpreted as a free text search
The ~
and !~
search operators are translated to the LIKE
and NOT LIKE
SQL queries respectively, which support two basic wildcards, _
and %
.
_
is a wildcard for a single character replacement. For example, the search name ~ fo_
will match both “foo” and “for”.
The %
and *
wildcard will replace zero or more characters. For example, the search name ~ corp%
will match both “corp” and “corporation”. The more common ‘*’ wildcard is not a SQL wildcard but may be used instead.
When the ~
or !~
search is processed, a ‘%’ wildcard is automatically added at the beginning and end of the value if no wildcard is used, so it will by default match at any location inside a string. For example, the search name ~ foo
is equivalent to name ~ %foo%
and the search name ~ foo%
will only match “foo” at the beginning of the value.
Many date and time formats are accepted in search queries. Here are some examples:
The date can have different separators, “10-July-2011” will be interpreted in the same way as “10/July/2010” or “10 July 2011” Month names may be the full English name or a three letter abbreviation, e.g. “Jan” will be interpreted as “January”. Many other formats are also acceptable, however it is not recommended to use ambiguous formats such as “3/4/2011”
The valid date time operators are ‘=’, ‘<’ and ‘>’ which are interpreted as ‘at’, ‘before’ and ‘after’ respectively. This is how the search term interpeted:
The right hand part of a date-time condition is parsed and translated into a specific date-time, “30 minutes ago” is translated to “now - 30 minutes”.
last_report > "2011-07-01 12:57:18 EDT"
should be read as created after this timelast_report > "30 minutes ago"
should be read as “created after 30 minutes ago” and not “created more then 30 minutes ago”A search query like installed_at = Yesterday
is translated into a period query, it will be translated at runtime to match a range of date-times. For example, if running on Jan 1, it would be translated into “(installed_at >= Jan 1,2012 00:00) and (installed_at < Dec 31,2011 00:00)”.
Foreman is all about hosts and users interacting with these hosts.
Each Foreman user can have multiple SSH keys assigned when editing a user. These keys alone do not serve any purpose, but are available for use in provisioning templates and can be accessed via ENC data. They provide an easy way to manage users and login ssh keys on hosts without the need for LDAP.
If you want users to be able to login to a host using the data provided in Foreman, you need to include the create_users
snippet in your provisioning template. There is a puppet module available to keep user data in sync with Foreman and your hosts.
In this section we’ll look at the various ways we can control and interact with Puppet.
Puppet environments are mapped directly into Foreman. They can be used at various levels throughout the Foreman interface. Puppet environments are generally used to separate classes from different types of Host, typically allowing changes to a module to tested in one environment (e.g. development) before being pushed to another (e.g production).
There are several ways to create Puppet environments within Foreman.
Foreman can detect all the environments and classes contained on a Puppet server, and import them automatically. To do this, go to Configure > Environments and click on Import from <proxy-name>. Foreman will scan the Puppet server via the Smart Proxy, and display a confirmation of the detected changes. Select the changes you wish to apply and confirm.
More information about configuring the Smart Proxy to read environments and Puppet classes is in the Smart Proxy Puppet section.
Note that the Smart Proxy will only detect environments that contain one or more Puppet classes, so ensure that at least one Puppet module containing a class has been deployed to the Puppet server.
To create an environment by hand, simply go to Configure > Environments and click New Puppet Environment. Give the new environment a name and save. Note that if the environment doesn’t exist on the Puppet server and you subsequently run an import (above), Foreman will prompt for the environment to be deleted.
This is done from the Host Edit page, on the Host tab. Selecting an environment will filter the classes visible on the Puppet Classes tab to just the classes in the selected environment.
You can also also mass-assign an environment to a group of hosts - tick the checkboxes of the required hosts in the Hosts list, and then select Change Environment from the Select Action dropdown menu at the top of the page.
You can assign an environment to a hostgroup as well. This functions as a form of default - a user creating a new host and selecting the hostgroup will automatically have the environment pre-selected. The user is not prevented from changing the environment of the new host, it simply saves a few clicks if they are happy with it.
Puppet classes are generally imported from the Puppet server(s) via the Import button on the Puppet Classes page. They can also be created by hand, and manually associated with a set of environments (for filtering purposes).
Go to Configure > Classes and click the Import button. This will not be visible unless you have at least one Puppet server with a puppet-enabled Smart Proxy. Only classes from modules will be imported, and the Puppet manifests must be valid in order for the Smart Proxy to parse them. Use puppet parser validate
to test the syntax of Puppet manifests.
More information about configuring the Smart Proxy to read environments and Puppet classes is in the Smart Proxy Puppet section.
Under Configure > Classes you will also see a column called “Hosts”. This column represents the number of hosts the given module/class has been assigned to. Clicking this figure will list the hosts.
It’s often to have a module structure like this:
In this situation, Foreman would offer to create:
However, if we know that the subclasses are not intended for direct consumption, but are only really part of the internal structure of the module, then we would want to exclude those from the import mechanism, so that Foreman only offers to import git. We can achieve this via the file /usr/share/foreman/config/ignored_environments.yml.
This file is read during each import, causing Foreman to ignore changes to the listed environments or Puppet classes that match the expressions in the file. It will not delete any environments or classes already in Foreman.
Entire environments can be ignored with this configuration:
Classes can be ignored using a set of regular expressions - any class which matches one of them will not be imported. So, for the above example, we might configure:
Regular expression features such as negative lookaheads can be used for more advanced filtering, e.g. to ignore all classes except for those starting with “role::”, the following syntax can be used:
To cause Puppet to apply your classes, you will need to assign them to your hosts. This can be achieved in a number of ways - the best method may vary depending on how many classes you intend to assign and whether any parameters need to be overridden.
When editing a host, Puppet classes may be assigned directly under the Puppet Classes tab. All classes that are in the Puppet environment selected on the first Host tab will be listed.
Host groups tend to correspond to an infrastructure role as each host may be assigned to a single host group, and typically inherits most of its Puppet classes in this way.
Puppet classes can be assigned by editing the host group and selecting them on the Puppet Classes tab.
Most host group attributes are copied to a host when it is created, however Puppet class associations remain inherited from the host group throughout its lifetime. Any change to a host group’s assigned Puppet classes or parameters will affect any host with that host group set.
The Puppet environment attribute may be different on the host to the host group, which means that Puppet classes assigned to the host group may not exist in the host’s own Puppet environment. Any Puppet classes that are inherited from the host group, but do not exist in the host’s environment will be left out when Foreman renders the ENC (YAML) output. Check under Configure > Puppet classes that the classes are available in both the host group and host environments if they differ.
You can also also mass-assign a host group to a number of hosts - tick the checkboxes of the required hosts in the Hosts list, and then select Change Group from the Select Action dropdown menu at the top of the page.
A config group provides a one-step method of associating many Puppet classes to either a host or host group. Typically this would be used to add a particular application profile or stack in one step.
To create a config group, click on Configure > Config groups, click New Config Group, enter a name and select the desired Puppet classes. When editing either a host or host group, the new config group can be added at the top of the Puppet Classes tab.
Config groups are not specific to an environment and so only those Puppet classes that are in the host’s environment when rendering the ENC (YAML) will be listed. Any classes that are not listed in the environment (as per Configure > Classes) will be left out.
Note that it isn’t possible to use a smart class parameter override with a config group, as a host may have many config groups with no way to define an order of precedence. Overrides should be made on a host group, host or other attribute.
To see how Foreman is passing the classes to Puppet, go to a Host and click the YAML button. You will be shown the exact YAML data sent to the Puppet server - the classes will be in the “classes” hash.
Foreman can pass two types of parameters to Puppet via the ENC (External Node Classifier) interface - global parameters (accessible from any manifest), and class parameters (scoped to a single Puppet class). These can be added in a number of ways through Foreman.
Generally speaking, it’s best to use class parameters where possible, as this makes designing, using and sharing Puppet modules and classes easier. The class may clearly specify which parameters it expects, provide sensible defaults and allow users to override them. Foreman is also able to import information about class parameters automatically, making it easier to consume new classes without needing to know and enter the precise names of global parameters.
In Puppet’s DSL, accessing a global parameter or variable is done using $::example
(preferred) or $example
for a parameter named “example” in Foreman. More information about accessing variables is available in the Puppet Language: Variables documentation. When looking at the ENC (YAML) output from Foreman, a global parameter will look like this:
When using class parameters, a class will first be defined with a parameter and may be accessed either using the local name or fully-qualified, e.g.
When looking at the ENC (YAML) output from Foreman, a class and class parameter will look like this:
Global parameters in Foreman can be added in the following places:
Class parameters in Foreman can be set in:
Host inherit their list of global parameters from the following locations, in order of increasing precedence:
The final (most specific) level of global parameters applies only to a single host. Edit a Host and switch to the Parameters tab, and you will see all of its inherited parameters from the previous levels. You can override any of these previously-defined parameters or define new ones here.
Global parameters support multiple data types and validation as per type selected. With types support, searching by parameter value is no longer allowed.
To see how Foreman is passing the parameters to Puppet, go to a Host and click the YAML button. You will be shown the exact YAML data sent to the Puppet server - the parameters will be in the “parameters” hash.
Parameterized class support permits detecting, importing, and supplying parameters direct to classes which support it, via the ENC. This requires Puppet 2.6.5 or higher.
By default, parameterized class support is enabled in Foreman. This can be checked from Administer > Settings > Puppet and ensure Parametrized_Classes_in_ENC is set to true.
Now you’ll need to import some parameterized classes from your Puppet server. If you don’t have any parameterized classes in your modules dir, the foreman-installer has several, you can download a few modules from the Puppet Forge. Once you have some parameterized modules, import your classes (see 4.2.2 Classes)
This example will work with the foreman class from the installer. Click on the class, and you should get a page with 3 tabs, like so:
The middle tab, “Smart Class Parameter”, is the important one. Click onto that, and you should see something like this:
On the left, we have a list of possible parameters that the class supports. On the right, we have the configuration options for the parameter selected.
Lets configure the foreman class to change the user the foreman processes run as. Select the user parameter, at the end of the list. Now lets go through the options:
Ok, so let’s configure our user parameter. We want to tick Override, set type to “String” and set the default value to “foreman”, like so:
Most importantly, the Override option has to be enabled for Foreman to control this variable, otherwise it will never be managed and will not appear in the ENC output.
The Default value will be supplied in the ENC output and should be a supported value, such as a string, YAML or JSON structure or use template features (see following sections). When the Omit checkbox is enabled, no default value will be present in the ENC output unless an override matches. Puppet will instead use the class default or data binding (Hiera) as usual.
The default will be imported from the Puppet manifest initially, but if the class uses an inherited params pattern, it may contain an unhelpful string such as ${$foreman::params::user}
. Foreman is unable to parse the actual value in this case as it might change when evaluated. Change the suggested default to the actual value, or tick the Omit checkbox.
We’ve configured the default, but that’s not very useful. We need to be able to override the default for hosts or groups of hosts. To do that we need the “Override Value For Specific Hosts” section at the bottom of the page.
Let’s say that any machine in the “development” Puppet environment should use a value of “foremandev” instead of “foreman” for the “user” parameter. Add “environment” to the end of the matchers list, then click the “New Matcher-Value” button, and fill it out like this:
This is a basic configuration - for more complex examples of using matchers, see the Smart Matchers section.
If Foreman manages the value of a class parameter (“override = true”), it’s also possible to update a host-specific override from the host itself. That way you don’t have to grant access to the Puppet Classes page to everyone. From a Host, click Edit, go to the Parameters tab, and you’ll see the variable, the class-scope, and the current value. You can then override the value for that host:
If the value is hidden you can click the unhide button to temporarily see the value while you edit. Clicking the button won’t change the hidden property for the parameter, only show it for editing purpose.
If you go back and look at the Puppet class, you’ll see Foreman has added a matcher for that host:
The same override button is available on a host group’s Parameters tab. For more complex logic, like matching on facts, use the Puppet Class page.
Smart class parameters are based on the smart matchers technology, and have a number of advanced features such as validation and multiple data types. More about these can be found in the Smart Matchers section.
The smart matching technology underpins smart class parameters, so is described below. It provides the following features for each parameter:
Overrides are processed in the order of precedence set in the Order field, from most to least specific (first match wins, unless merging is enabled). This is a list of host attributes and fact names that overrides will be checked against. If no override from this list matches, the default value is used.
Example attributes that may be listed are:
fqdn
- host’s FQDN (“host.example.com”)hostgroup
- full name of the host group, including parents (“Europe/Web servers”). Matchers on host groups can be inherited by their children, see documentation for matchers_inheritance
in configuration options.os
- name and version of operating system (“RedHat 6.4”)domain
- host’s domain name (“example.com”)location
or organization
- full name of the location/organization, including parents (“Company/Subsidiary”). Matchers on location/organization can be inherited by their children, see documentation for matchers_inheritance
in configuration options.is_virtual
- a fact supplied by FacterThe default order is set under Administer > Settings > Puppet > Default_variables_Lookup_Path and is “fqdn”, “hostgroup”, “os”, “domain”.
Note that there’s a name conflict between the “operatingsystem” fact and Foreman’s attribute “operatingsystem” (same as “os” above), and Foreman’s attribute will be the one that is used, so will include the version number.
Once defaults have been filled in for your parameter, you can then add criteria to match against - click the Add Matcher button under your parameter, and more input fields will appear:
Attribute type | Should state a name = value relationship that Foreman use to match against the entries in the order list |
Value | What the parameter should be in the ENC, if this rule is matched |
Omit | Instead of providing a value, this parameter will not be supplied in the ENC output (use to prevent a default value being returned) - only for smart class parameters |
As an example, let’s say that any machine in the “development” puppet environment should use a value of “foremandev” instead of “foreman” for the “user” parameter. Add “environment” to the end of the matchers list, then click the Add Matcher-Value button, and fill it out like this:
The match field currently supports string equality only, the values must match exactly.
When the data type is a hash or array, ticking Merge overrides will cause values from every override that matches (e.g. an FQDN and domain) to be merged together.
Merging is “deep”, so nested hashes and arrays will gain values rather than being overwritten entirely.
The Merge default option adds the default value as one of the values to merge, it will get the least important priority so one of the other values may overwrite it.
When the data type is an array, the Avoid duplicates option will de-duplicate the resulting array.
The type of data we want to pass to Puppet can be set in the Parameter type field. Most commonly a string, but many other data types are supported:
There’s no easy way to tell what type of data the Puppet manifest is expecting, so you will need to read through the code/documentation that comes with a particular module to find out. Changing the type field requires an appropriately set “Default Value” field.
Here’s an example of adding an array parameter. Note the use of YAML in the edit box:
This will be converted to the JSON ["a","b"]
syntax when you save. You can also use hashes in YAML or JSON as data types too.
Note that the JSON hash syntax is not the same as Puppet’s hash syntax: {"example":"value"}
The Optional input validator section can be used to restrict the allowed values for the parameter. It is important to note that the validation applies to changes made from the Host edit page as well as the Puppet Classes edit page.
The input validation section is hidden by default but can be opened by clicking on its title. When changing the parameter type this section will be automatically expanded to change the validations according to the new type.
Validator type | A combobox of data types. The type applies to the next field, the validator. |
Validator rule | Used to enforce certain values for the parameter values. See below for examples. |
For example, to restrict the “user” field to either “foreman” or “foremandev”, tick the Required checkbox, and then set:
At present, the string type cannot be validated - leave the validator field blank, and all strings in the variable will be considered acceptable
By entering a list (comma-separated, no spaces) or a regex (no delimiter required), the value to be assigned to the parameter will be checked against this list. If the value does not match the validator, and error will be raised.
Because Foreman offers templating capabilities, you can utilise pre-existing variables, macros and or functions within your parameterized classes. This is especially useful if you need to send a string to Puppet, but have a need to embed host specific information within the string, such as the host’s FQDN.
Let’s look a quick example situation: we need to configure RabbitMQ and have it use our existing Puppet SSL certs. Using what we’ve learnt above, we jump into the RabbitMQ class and configure the “ssl cert” parameter as such:
As you can see we’re utilising a template variable within the parameter’s string just like we would in a normal template file. The important part of this string, as we’re sure you’ve gathered, is the “@host.name” element. This pulls the FQDN from Foreman’s facts and inserts it into the string.
More information regarding templates can be found in the Template Writing Reference. This page also contains the pre-existing functions and macros you can use in your templates and parameter classes..
All our hosts use server.foo for something, except bob.domain.com which uses server2.bar:
Parameter | target |
Description | The target server to talk to |
Default Value | server.foo |
Type Validator | string |
Validator Constraint | |
Order | fqdn hostgroup os domain |
Attribute type | fqdn = bob.domain.com |
Value | server2.bar |
Most hosts need to use a port of 80 but all machines with a fact region and value europe need to use 8080. To do this, you have to add the factname (in this example region) to the searchlist:
Parameter | port |
Description | The port to use |
Default Value | 80 |
Type Validator | list |
Validator Constraint | 80,443,8080 |
Order | fqdn region hostgroup os domain |
Attribute type | region = europe |
Value | 8080 |
Attribute type | fqdn = foo.domain |
Value | 67 |
Note that all machines will get either 80 or 8080 as required, except foo.domain which will generate an error, since 67 is not in the list validator. Note also that foo.domain will match before region, since it is higher in the searchlist. The rule ordering does not matter.
It is also possible to mix conditions, e.g.
Parameter | port |
Description | The port to use |
Default Value | 80 |
Type Validator | list |
Validator Constraint | 80,443,8080 |
Order | fqdn region, hostgroup, environment hostgroup environment domain |
Attribute type | fqdn = foo.domain |
Value | 67 |
Attribute type | region, hostgroup, environment = europe, "web servers", production |
Value | 8080 |
The Smart Proxy is a project which provides a restful API to various sub-systems.
Its goal is to provide an API for a higher level orchestration tools (such as Foreman). The Smart proxy provides an easy way to add or extended existing subsystems and APIs using plugins.
Currently supported (Click on the links below for more details).
If you require another sub system type or implementation, please add a new feature request or consider writing a plugin.
Once your smart proxy is running, each of the relevant sub systems needs to be configured via the settings.d/* files in the config directory.
A smart proxy is an autonomous web-based foreman component that is placed on a host performing a specific function in the host commissioning phase. It receives requests from Foreman to perform operations that are required during the commissioning process and executes them on its behalf. More details can be found on the Foreman Architecture page.
To fully manage the commissioning process then a smart proxy will have to manipulate these services, DHCP, DNS, Puppet CA, Puppet and TFTP. These services may exist on separate machines or several of them may be hosted on the same machine. As each smart proxy instance is capable of managing all the of these services, there is only need for one proxy per host. In the special case of a smart proxy managing a Windows DHCP server, the host machine must be running Windows, it does not need to be the Microsoft DHCP server itself.
RPM and Debian packages are available, see the Install from Packages section for configuration and install the foreman-proxy
package.
You can get the latest stable code from GitHub (via git).
git clone git://github.com/theforeman/smart-proxy.git -b 3.10-stable
The smart proxy will run with the following requirements (aside from rubygem dependencies):
The Microsoft smart-proxy installation procedure is very basic compared to the RPM or APT based solution. You need to run smart-proxy from the source as well as install Ruby and Ruby DevKit.
%PATH%
, you can select this option in the installercmd.exe
) and run the following commands in order:
ruby <devKitRoot>\dk.rb init
ruby <devKitRoot>\dk.rb install
gem install --no-ri --no-rdoc bundler
cd <smart-proxy location>
bundle install --without development test krb5 puppet_proxy_legacy bmc libvirt
On the command line, type the following command. Take care not to use an alias nor upper case characters.
puppet cert generate new-smart-proxy-FQDN
<smart-proxy location>\ssl\
(create the directory if necessary - this location will be referred to by the settings.yml in the next step):bind_host:
and :log_file:
and SSL, for example::bind_host: '0.0.0.0'
:log_file: 'C:\smart-proxy.log'

:ssl_private_key: <smart-proxy location>\ssl\host.example.com.pem
:ssl_ca_file: <smart-proxy location>\ssl\ca.pem
:log_level: DEBUG
and :log_file: STDOUT
in config/settings.ymlbundle exec ruby <smart-proxy location>\bin\smart-proxy
ruby extra\register_service.rb
to register the service Foreman Smart Proxy
. Alternatively, use a third party tool like NSSM to create the service.Caveats: There is an issue with DevKit not finding any ruby version installed. Check that the DevKit and Ruby Installer are both x32 or x64, otherwise add the missing versions manually by editing config.yml
.
Puppet hint: If you have Puppet installed on the same host running smart-proxy, you can use Puppet’s Ruby. You only need DevKit. In this case, just add directory containing ruby.exe
to your path variable and add it to DevKit settings if necessary by editing DevKit’s config.yml
. Also, you might want to use Puppet’s host certificates right away for smart proxy SSL connections. Usually, they can be found in C:\ProgramData\PuppetLabs\puppet\etc\ssl
. For example:
:ssl_certificate: C:\ProgramData\PuppetLabs\puppet\etc\ssl\certs\host.example.com.pem
:ssl_private_key: C:\ProgramData\PuppetLabs\puppet\etc\ssl\private_keys\host.example.com.pem
:ssl_ca_file: C:\ProgramData\PuppetLabs\puppet\etc\ssl\certs\ca.pem
Usually can be found at /etc/foreman-proxy/settings.yml or in the config/settings.yml subdirectory. You can use the settings.yml.example file inside the config directory as a template for your own settings.yml.
Configuration of each subsystem is usually in /etc/foreman-proxy/settings.d/ or in the config/settings.d/ subdirectory. If you don’t plan to use one of the subsystems, please disable them in these configuration files. For more information see Smartproxy Configuration.
bundle exec bin/smart-proxy
Or if you installed it via a package simply start the foreman-proxy service.
service foreman-proxy start
For example:
The main configuration for the core Smart Proxy is held in the /etc/foreman-proxy/settings.yml or config/settings.yml file. This includes configuration of ports to listen on, SSL and security settings and logging options.
Each of the modules used in the Smart Proxy have their configuration in the /etc/foreman-proxy/settings.d/ or config/settings.d directory. Modules are enabled or disabled inside their respective configuration files with the :enabled
directive, which determines whether the module is available on HTTP, HTTPS, both or is disabled (see below for more details).
The first non-comment line of all configuration files must be three dashes.
---
The proxy’s output is captured to the log_file and may be filtered via the usual Unix syslog levels:
See Ruby’s Logger class for details.
:log_file: /var/log/foreman-proxy/proxy.log
:log_level: DEBUG
The log_file setting may be set to “STDOUT” which causes log messages to be logged to standard output, for capture by the running process (e.g. systemd with journal). When log_file is set to “SYSLOG”, all messages will be sent to syslog.
A limited number of recent log messages are kept in memory using a ring buffer, which can be exposed in the API and to Foreman by enabling the Logs feature.
The number of all log messages is controlled by the log_buffer
setting, and a second buffer of error messages is controlled by the log_buffer_errors
setting. The total of the two will directly affect the maximum amount of memory used, which is approximately 500kB in the default configuration of 3,000 recent messages.
:log_buffer: 2000
:log_buffer_errors: 1000
By default the Smart Proxy listens on all interfaces, which can be changed to limit access to a network:
# host to bind ports to (possible values: *, localhost, 0.0.0.0)
:bind_host: ['*']
:bind_host: private.example.com
:bind_host: 192.168.1.10
The Smart Proxy has a number of different modules which can be enabled either for HTTP, for HTTPS or for access on both services. It is highly recommended to enable most only on HTTPS and only enable modules on HTTP when required (e.g. templates) or if no SSL is desired.
The two port options control which TCP port(s) the Smart Proxy will listen on. At least one must be enabled for the proxy to start. It is recommended to only set https_port unless an HTTP-only module is active, which also requires the three ssl_* settings to be set.
:http_port: 8000
:https_port: 8443
Modules are enabled in their per-module configuration file in /etc/foreman-proxy/settings.d/ with the :enabled
directive, which can be set to:
:enabled: false
to disable the module entirely:enabled: http
to listen on HTTP only:enabled: https
to listen on HTTPS only (recommended):enabled: true
to listen on both HTTP and HTTPS if enabled (not recommended)The existence of all the three ssl key entries below requires the use of an SSL connection.
NOTE that both client certificates need to be signed by the same CA, which must be in the ssl_ca_file, in order for this to work see SSL for more information
:ssl_certificate: ssl/certs/fqdn.pem
:ssl_ca_file: ssl/certs/ca.pem
:ssl_private_key: ssl/private_keys/fqdn.key
Specific SSL cipher suites can be disabled by using the :ssl_disabled_ciphers:
option. For more information on which cipher suites are enabled by default and how to correctly disable specific ones, please see SSL cipher suites.
The TLS versions can be disabled if requiring a specific version. SSLv3, TLS v1.0, and TLS v1.1 are disabled by default, setting the array of :tls_disabled_versions:
to include 1.2
will disable this version, too.
This is the list of hosts from which the smart proxy will accept connections. For HTTPS connections, the name must match the common name (CN) within the subject DN and for HTTP connections, it must match the hostname from reverse DNS.
:trusted_hosts:
- foreman.prod.domain
- foreman.dev.domain
For HTTPS connections, the name must match the common name (CN) within the subject DN and for HTTP connections, it must match the hostname from reverse DNS. When :forward_verify
is enabled (default: true) then the reverse lookup is verified against the forward lookup of the hostname (aka forward-confirmed reverse DNS/FCrDNS).
Some modules may allow connections from all hosts rather than only the trusted_hosts list, particularly if they intend to deal with requests directly from managed hosts rather than only from Foreman.
An empty trusted_hosts list will permit no hosts access:
:trusted_hosts: []
While if the setting is not specified, any host may make requests to the smart proxy, which permits management of any enabled modules and features.
Some modules make requests back to Foreman, e.g. when relaying requests from client hosts. The following setting changes the destination URL:
:foreman_url: https://foreman.example.com
And the following settings change the SSL certificates used to authenticate to Foreman and to verify its certificate. In a typical installation, Foreman and the Smart Proxy may both use certificates signed the same certificate authority, so these default to the values of the ssl_* settings defined above.
# SSL settings for client authentication against Foreman. If undefined, the values
# from general SSL options are used instead. Mainly useful when Foreman uses
# different certificates for its web UI and for smart-proxy requests.
:foreman_ssl_ca: /etc/foreman-proxy/ssl/certs/ca.pem
:foreman_ssl_cert: /etc/foreman-proxy/ssl/certs/fqdn.pem
:foreman_ssl_key: /etc/foreman-proxy/ssl/private_keys/fqdn.pem
Activate the BMC management module within the Smart Proxy instance. This allows users to trigger power management commands through the proxy to controlled hosts using IPMI or similar.
:enabled: https
:bmc_default_provider: freeipmi
Available providers are:
freeipmi
- for IPMI control using the freeipmi implementationipmitool
- using the ipmitool implementationshell
- specialized provider for controlling the proxy server itself (used for Foreman Discovery)ssh
- simple provider via SSH command shutdown
with limited functionality (poweron does not work)The credentials and addresses used to control hosts are passed from Foreman itself by adding a new network interface with the type set to “BMC” to hosts.
The SSH BMC provider provides a limited level of BMC functionality by running commands over an SSH connection to the host using a trusted SSH key.
It has the following configuration options for authentication, for the remote SSH user and private SSH key:
:bmc_ssh_user: root
:bmc_ssh_key: /usr/share/foreman/.ssh/id_rsa
The following configuration options control the commands executed by the provider on the remote host:
:bmc_ssh_powerstatus: "true"
:bmc_ssh_powercycle: "shutdown -r +1"
:bmc_ssh_poweroff: "shutdown +1"
:bmc_ssh_poweron: "false"
No power on support is possible with this provider.
Activate the DHCP management module within the Smart Proxy instance. This is used to query for available IP addresses (looking at existing leases and reservations), add new and delete existing reservations. It cannot manage subnet declarations, which should be managed by another means (e.g. puppet-dhcp).
The DHCP module is capable of managing the ISC DHCP server, Microsoft Active Directory and Libvirt instances.
Builtin providers are:
dhcp_isc
- ISC DHCP server over OMAPIdhcp_libvirt
- dnsmasq DHCP via libvirt APIdhcp_native_ms
- Microsoft Active Directory using APIExtra providers are available as plugins and can be installed through packages. See the following pages for more information:
To enable the DHCP module and enable a provider, dhcp.yml
must contain:
:enabled: https
:use_provider: dhcp_isc
For providers from plugins, check the plugin documentation to determine the exact provider name.
The module manages a DHCP server on the local host by default, but for providers that can be run remotely, the server address can be changed:
:server: 127.0.0.1
Note that if the DHCP server is running remotely, some providers (notably ISC) require that the configuration files must be accessible to the Smart Proxy still. This can be achieved with a network file system, e.g. NFS.
All available subnets will be loaded and can be managed by default, but this can have a performance penalty. If only some subnets are used, specify them as follows in network_address/network_mask
notation:
:subnets: [192.168.205.0/255.255.255.128, 192.168.205.128/255.255.255.128]
Each provider has its own configuration file in the same directory with its own settings, e.g. dhcp_isc.yml
. This usually needs additional configuration after changing the use_provider
setting.
The dhcp_isc provider uses a combination of the ISC DHCP server OMAPI management interface and parsing of configuration and lease files. This requires it to be run either on the same host as the DHCP server or to have network filesystem access to these files.
This provider requires the config
and leases
settings in the dhcp_isc.yml
configuration file, which should be set to the location of the DHCP server config and lease files. On a Red Hat or Fedora server use:
:config: /etc/dhcp/dhcpd.conf
:leases: /var/lib/dhcpd/dhcpd.leases
On a Debian or Ubuntu DHCP server, use the following values instead:
:dhcp_config: /etc/dhcp3/dhcpd.conf
:dhcp_leases: /var/lib/dhcp3/dhcpd.leases
If the DHCP server is secured with an “omapi_key”, the following entries must be set with the same values:
:key_name: omapi_key
:key_secret: XXXXXXXX
If the DHCP server is listening on a non-standard OMAPI port (i.e. not 7911), then change this with:
:omapi_port: 7911
For DHCP servers running on a different host, change :server
in the main dhcp.yml
configuration file.
The native_ms provider manages reservations in Microsoft Active Directory via its native API.
Possible configuration options in dhcp_native_ms.yml
are:
:disable_ddns: true
When disable_ddns
is true (default), dynamic DNS updates will be disabled for all hosts that the smart proxy creates. This will slightly slow the host creation process but will ensure that the DHCP server will not create or delete DNS entries on behalf of these clients. It’s preferable to disable this feature at the scope level.
Provider that manages reservations and leases via dnsmasq through libvirt API. It uses ruby-libvirt gem to connect to the local or remote instance of libvirt daemon.
Possible configuration options in dhcp_libvirt.yml
are:
# Libvirt network. Only one network is supported.
:network: default
# Libvirt connection. Make sure proxy effective user have permission to connect.
:url: qemu:///system
When configuring local or remote connections, make sure the foreman-proxy
effective user has UNIX permissions to libvirt socket or ssh keys are
deployed when using remote connection.
More information about using this provider is in the Libvirt section.
ISC implementation is based on the OMAPI interface, which means:
omapi-port 7911;
The dhcpd api server will listen to any host. You might need to add a omapi_key to provide basic security.
Example generating a key (on CentOS):
yum install bind
dnssec-keygen -r /dev/urandom -a HMAC-MD5 -b 512 -n HOST omapi_key
cat Komapi_key.+*.private |grep ^Key|cut -d ' ' -f2-
omapi-port 7911;
key omapi_key {
algorithm HMAC-MD5;
secret "XXXXXXXXX"; #<-The output from the generated key above.
};
omapi-key omapi_key;
Make sure you also add the omapi_key to your proxy’s dhcp_isc.yml
Restart the dhcpd and foreman-proxy services
NOTE: if you don’t see DHCP in Smart Proxies Features, choose “Refresh features” from drop-down menu.
The next step is to set up appropriate Subnets in Foreman from the settings menu.

}
It is required that this procedure is executed as an administrator.
It is not required that the smart proxy be on the same host as the MS DHCP server. The smart proxy just needs to be on a Windows host with connectivity to the DHCP server. If this is the case, make sure the smart proxy service runs as a user with sufficient privileges.
Note: Refer to the installation guide for general setup.
Edit config/settings.d/dhcp.yml so that it looks a bit like this. :server:
can be left commented out if smart proxy runs on the same host.
Sample config/settings.d/dhcp.yml file

Activate the DNS management module within the Smart Proxy instance. This is used to update and remove DNS records from existing DNS zones.
The DNS module can manipulate any DNS server that complies with the ISC Dynamic DNS Update standard and can therefore be used to manage both Microsoft Active Directory and BIND servers. Updates can also be made using GSS-TSIG, see the second section below. Additional providers are available for managing libvirt’s embedded DNS server (dnsmasq) and Microsoft Active Directory using dnscmd, for static DNS records, avoiding scavenging.
Builtin providers are:
dns_nsupdate
- dynamic DNS update using nsupdatedns_nsupdate_gss
- dynamic DNS update with GSS-TSIGdns_libvirt
- dnsmasq DNS via libvirt APIdns_dnscmd
- static DNS records in Microsoft Active DirectoryExtra providers are available as plugins and can be installed through packages. See the following pages for more information:
To enable the DNS module and enable a provider, dns.yml
must contain:
:enabled: https
:use_provider: dns_nsupdate
For providers from plugins, check the plugin documentation to determine the exact provider name.
The default TTL of DNS records added by the Smart Proxy is 86400 seconds (one day). This can be changed with the dns_ttl setting:
:dns_ttl: 86400
Each provider has its own configuration file in the same directory with its own settings, e.g. dns_nsupdate.yml
. This usually needs additional configuration after changing the use_provider
setting.
The dns_nsupdate provider uses the nsupdate
command to make dynamic updates to the DNS server records. This works on a wide variety of RFC2136-compliant servers.
DNS servers that support Kerberos authentication, e.g. FreeIPA or Microsoft Active Directory, should use the dns_nsupdate_gss provider instead.
This provider has the following settings in the dns_nsupdate.yml
configuration file:
#:dns_key: /etc/rndc.key
:dns_server: localhost
The dns_key specifies a file containing a shared secret used to generate a signature for the update request (TSIG record), thus authenticating the smart proxy to the DNS server.
If neither the dns_key or GSS-TSIG is used then the update request is sent without any signature. Unsigned update requests are considered insecure. Some DNS servers can be configured to accept only signed signatures.
The dns_server option is used if the Smart Proxy is not located on the same physical host as the DNS server. If it is not specified then localhost is presumed.
:dns_key: /etc/foreman-proxy/Kapi.+157+47848.private
:dns_server: dnsserver.site.example.com
For servers that support Kerberos/GSS-TSIG to authenticate DNS updates, the dns_nsupdate_gss provider should be used. This typically applies to FreeIPA and Microsoft Active Directory servers. This is equivalent to the nsupdate -g
command.
This provider has the following settings in the dns_nsupdate_gss.yml
configuration file:
:dns_tsig_keytab: /usr/share/foreman-proxy/dns.keytab
:dns_tsig_principal: DNS/host.example.com@EXAMPLE.COM
See the section on GSS-TSIG DNS below for steps on setting up the requisite accounts and keytabs with both AD and FreeIPA.
The dns_server option is used if the Smart Proxy is not located on the same physical host as the DNS server. If it is not specified then localhost is presumed.
:dns_server: dnsserver.site.example.com
While the dns_nsupdate
provider creates dynamic records in Active Directory, the dns_dnscmd
provider uses the dnscmd
tool to create static DNS records in AD, which are not affected by scavenging. This requires that the Smart Proxy is installed on a Windows server with dnscmd
available.
The dns_server option is used if the Smart Proxy is not located on the same physical host as the DNS server. If it is not specified then localhost is presumed.
:dns_server: dnsserver.site.example.com
Provider that manages reservations and leases via dnsmasq through libvirt API. It uses ruby-libvirt gem to connect to the local or remote instance of libvirt daemon.
Possible configuration options in dns_libvirt.yml
are:
# Libvirt network. Only one network is supported.
:network: default
# Libvirt connection. Make sure proxy effective user have permission to connect.
:url: qemu:///system
When configuring local or remote connections, make sure the foreman-proxy
effective user has UNIX permissions to libvirt socket or ssh keys are
deployed when using remote connection.
More information about using this provider is in the Libvirt section.
Bind configuration manipulation is based on nsupdate, which means that in theory could also be used to manipulate other dns servers which support nsupdate (such as Microsoft DNS server).
In order to communicate securely with your dns server, you would need a key which will be used by nsupdate and your named daemon using ddns-confgen or dnssec-keygen
execute ‘ddns-confgen -k foreman -a hmac-md5’ - this should output something like the following:
# To activate this key, place the following in named.conf, and
# in a separate keyfile on the system or systems from which nsupdate
# will be run:
key "foreman" {
algorithm hmac-md5;
secret "GGd1oNCxaKsh8HA84sP1Ug==";
};
# Then, in the "zone" statement for each zone you wish to dynamically
# update, place an "update-policy" statement granting update permission
# to this key. For example, the following statement grants this key
# permission to update any name within the zone:
update-policy {
grant foreman zonesub ANY;
};
# After the keyfile has been placed, the following command will
# execute nsupdate using this key:
nsupdate -k /path/to/keyfile
You should create a new file (such as /etc/rndc.key or other) and store the key “foreman {…} in it. in the proxy Settings file you should point to this file location - make sure that the proxy have read permissions to this file.
In your named file, you could add the update-policy statement or something like this named example file if you need more fine grained permissions.
Both BIND as configured in FreeIPA and Microsoft AD DNS servers can accept DNS updates using GSS-TSIG authentication. This uses Kerberos principals to authenticate to the DNS server. Under Microsoft AD, this is known as “Secure Dynamic Update”.
A user has to be created in Active Directory that will be used by the Smart Proxy, e.g. foremanproxy
. This will automatically create a service principal, e.g. foremanproxy@EXAMPLE.COM
.
Test the Kerberos login with that user on the Smart Proxy using kinit:
kinit foremanproxy@EXAMPLE.COM
This requires that your SRV records in DNS or /etc/krb5.conf file is setup correctly. By default many systems use DNS to locate the Kerberos DC. A KDC can also be statically set in this file. There are dozens of documents on how to do this on the net.
If login works, the keytab file can be created using ktutil
. First clear the Kerberos ticket cache:
kdestroy
Now create the keytab file with ktutil
:
ktutil: addent -password -p foremanproxy@EXAMPLE.COM -k 1 -e RC4-HMAC
ktutil: wkt dns.keytab
ktutil: q
Once the keytab file has been created, test it using kinit:
kinit foremanproxy@EXAMPLE.COM -k -t dns.keytab
If this works, clear the Kerberos ticket cache once again using kdestroy
.
Store the keytab at /etc/foreman-proxy/dns.keytab
, ensure permissions are 0600 and the owner is foreman-proxy
.
If you are using SELinux, do not forget to update the file context.
The DNS zone Dynamic Updates
option on the DNS zones can now be set to Secure Only
.
Restart the smart proxy service. Next, go to Update the configuration in Foreman.
A service principal is required for the Smart Proxy, e.g. foremanproxy/proxy.example.com@EXAMPLE.COM
.
First of all, create a new principal (FreeIPA service) for Foreman, e.g. ipa service-add foremanproxy/proxy.example.com@EXAMPLE.COM
.
Then fetch the keytab, e.g. ipa-getkeytab -p foremanproxy/proxy.example.com@EXAMPLE.COM -s ipa-server.example.com -k /etc/foreman-proxy/dns.keytab
.
Store the keytab at /etc/foreman-proxy/dns.keytab
, ensure permissions are 0600 and the owner is foreman-proxy
.
The ACL on updates to the DNS zone then needs to permit the service principal. In the FreeIPA web UI, under the DNS zone, go to the Settings tab, verify that “Dynamic update” for that zone is set to “True”, and add to the BIND update policy a new grant:
grant foremanproxy\047proxy.example.com@EXAMPLE.COM wildcard * ANY;
Note the \047
is written verbatim, and don’t forget the semicolon. ACLs should be updated for both forward and reverse zones as desired.
Update the proxy DNS configuration file (/etc/foreman-proxy/settings.d/dns.yml
) with the following setting:
:use_provider: dns_nsupdate_gss
And the DNS GSS configuration file (/etc/foreman-proxy/settings.d/dns_nsupdate_gss.yml
) with:
:dns_tsig_keytab: /etc/foreman-proxy/dns.keytab
:dns_tsig_principal: foremanproxy/proxy.example.com@EXAMPLE.COM
Ensure the dns_key
setting is not specified, or is commented out.
Restart the smart proxy service. Next, go to Update the configuration in Foreman.
After you have added a DNS smart proxy, you must instruct Foreman to rescan the configuration on each affected smart proxy by using the drop-down menu by its name and selecting “Refresh Features”.
Now, you are allowed to enable this in each subnet (reverse lookup of domain) and domain (forward lookup of domain) that you want this smart proxy to assist. You do this by navigating there and selecting it in the drop-down menu for DNS.
Activate the Puppet management module within the Smart Proxy instance. This module has two functions:
It should be activated on Puppetservers that have the environments and modules available to import data from. This works independently of the Puppet CA functionality. To use the Puppet run functionality, it also needs to configured via an implementation listed in the section below.
To enable this module, make sure these lines are present in /etc/foreman-proxy/settings.d/puppet.yml
:
:enabled: https
puppet parser validate example.pp
to validate the content of a manifest.To get a list of environments, classes and their parameters, the proxy queries the Puppetserver on its own API. The URL and settings used for the proxy to Puppetserver API query can be controlled with the following settings in /etc/foreman-proxy/settings.d/puppet_proxy_puppet_api.yml
:
# URL of the Puppet server itself for API requests
#:puppet_url: https://puppet.example.com:8140
#
# SSL certificates used to access the puppet API
#:puppet_ssl_ca: /etc/puppetlabs/puppet/ssl/certs/ca.pem
#:puppet_ssl_cert: /etc/puppetlabs/puppet/ssl/certs/puppet.example.com.pem
#:puppet_ssl_key: /etc/puppetlabs/puppet/ssl/private_keys/puppet.example.com.pem
#
# Smart Proxy api timeout when Puppet's environment classes api is used and classes cache is disabled
#:api_timeout: 30
The Puppetserver has to permit these API queries. The HOCON-formatted auth.conf style is at /etc/puppetlabs/puppetserver/conf.d/auth.conf and requires these rules:
{
match-request: {
path: "/puppet/v3/environments"
type: path
method: get
}
allow: "*"
sort-order: 500
name: "puppetlabs environments"
},
{
match-request: {
path: "/puppet/v3/environment_classes"
type: path
method: get
}
allow: "*"
sort-order: 500
name: "puppetlabs environment classes"
},
Activate the Puppet CA management module within the Smart Proxy instance. This is used to manage the autosign configuration and handle listing, signing and revocation of individual certificates.
Builtin providers are:
puppetca_hostname_whitelisting
- direct management of Puppet’s autosign.conf
puppetca_token_whitelisting
- manage token-based signing of certificate requestsThis should only be enabled in the Smart Proxy that is hosted on the machine responsible for providing certificates to your puppet clients. On this host enable the feature in puppetca.yml
:
:enabled: https
Also choose the provider to use, default should be puppetca_hostname_whitelisting
:
:use_provider: puppetca_hostname_whitelisting
The puppetca_hostname_whitelisting
provider directly manages Puppet’s autosign.conf
file.
This will create an autosign entry for a host during deployment and remove it when deployment is finished.
Furthermore it allows you to manage entries manually using the Foreman WebUI.
The autosignfile setting in puppetca_hostname_whitelisting.yml
is used to find autosign.conf:
:autosignfile: /etc/puppetlabs/puppet/autosign.conf
The location of the file can be determined with puppet config print autosign
.
The proxy requires write access to the puppet autosign.conf file, which is usually owner and group puppet, and has mode 0644 according to the puppet defaults. Ensure the foreman-proxy user is added to the puppet group ( e.g. gpasswd -a foreman-proxy puppet
or usermod -aG puppet foreman-proxy
)
puppet.conf:
[master]
autosign = $confdir/autosign.conf {owner = service, group = service, mode = 664 }
The puppetca_token_whitelisting
provider uses a token-based certificate signing managed by the Smart Proxy itself and queried by Puppet during Provisioning.
This provider adds more security and logging to the autosigning process but does not allow for manual creation of autosigning entries.
This provider has the following settings in puppetca_token_whitelisting.yml
:
:sign_all: false
:token_ttl: 360
:tokens_file: /var/lib/foreman-proxy/tokens.yml
By changing sign_all to true
you will disable token verification and sign all certificate requests.
The setting token_ttl defines how long a token after creation is valid in minutes.
tokens_file sets the path to the file used to store tokens during deployment, the foreman-proxy user requires read and write access to this file.
You can also change the certificate used for encrypting the token file by setting certificate. By default it uses the certificate of the Smart Proxy defined in settings.yml
as ssl_certificate.
To integrate this in Puppet the script puppet_sign.rb
provided by the Smart Proxy has to be used for verfication of the tokens during certificate signing.
If installed via package the script should be already located at /usr/libexec/foreman-proxy/puppet_sign.rb
.
For manual installation the script can be found on Github. Using the latest version should be fine, if you encounter problems try the one released with your Smart Proxy version.
The script has to be executable by the same user running the Puppet server, typically puppet.
After deploying the script the Puppet configuration has to be changed to point the autosign setting to the script.
[master]
autosign = /usr/libexec/foreman-proxy/puppet_sign.rb
As the name implies, Puppetserver’s HTTP API is used to manage certificates. In its configuration file puppetca_http_api.yml
the connection details are configured:
:puppet_url: https://puppet.example.com:8140
:puppet_ssl_ca: /etc/puppetlabs/ssl/certs/ca.pem
:puppet_ssl_cert: /etc/puppetlabs/ssl/certs/puppet.example.com.pem
:puppet_ssl_key: /etc/puppetlabs/ssl/private_keys/puppet.example.com.pem
The Puppet server does not need to be on the same host, but only the puppetca_token_whitelisting
provider supports this. Note the Puppetserver also needs to allow access to the Smart Proxy.
Activate the realm management module within the Smart Proxy instance. This manages Kerberos realms or domains, allowing Foreman to add and remove hosts to enable them to join the realm/domain automatically during provisioning.
:enabled: https
:use_provider: realm_freeipa
Builtin providers are:
realm_freeipa
- host object management in FreeIPAThe configuration for each provider should be in its respective file, i.e: /etc/foreman-proxy/settings.d/realm_freeipa.yml
.
The following settings control authentication of the proxy to the realm for management of hosts.
In realm_freeipa.yml
:
# Authentication for Kerberos-based Realms
:keytab_path: /etc/foreman-proxy/freeipa.keytab
:principal: realm-proxy@EXAMPLE.COM
The FreeIPA implementation of the realm proxy is able to add a host entry to FreeIPA, send the hostgroup name, and request a one-time registration password.
In order to create the realm user and keytab to authenticate to FreeIPA, you can use the included foreman-prepare-realm
tool. Your Smart Proxy must be registered to the FreeIPA realm already, and have the ipa-admintools package installed.
Simply provide a user with admin rights in FreeIPA, and a target user to create.
# foreman-prepare-realm admin realm-proxy
Password for admin@EXAMPLE.COM:
---------------------------------------
Added permission "modify host password"
---------------------------------------
Permission name: modify host password
Permissions: write
Attributes: userpassword
Type: host
[...]
Keytab successfully retrieved and stored in: freeipa.keytab
Realm Proxy User: realm-proxy
Realm Proxy Keytab: /root/freeipa.keytab
Copy the freeipa.keytab created above to /etc/foreman-proxy/freeipa.keytab and set the correct permissions:
chown foreman-proxy /etc/foreman-proxy/freeipa.keytab
chmod 600 /etc/foreman-proxy/freeipa.keytab
Then update settings.d/realm_freeipa.yml
with the relevant settings.
If you’re using FreeIPA to manage DNS records, and want them to be automatically deleted when the host is deleted in Foreman, set this to true:
:remove_dns: true
Finally, trust the IPA Certificate Authority. Ensure you have the most up-to-date version of the ca-certificates
package installed.
cp /etc/ipa/ca.crt /etc/pki/ca-trust/source/anchors/ipa.crt
update-ca-trust enable
update-ca-trust
You will need to disable the DNS proxy for hosts that are provisioned with a realm set, as FreeIPA adds the forward record for you. In order to support adding a reverse lookup record also, you will need to go into the settings for the forward lookup zone on the IPA server and tick Allow PTR sync
. This will make sure that FreeIPA creates the PTR records for you.
FreeIPA supports the ability to setup automember rules based on attributes of a system. When using the FreeIPA proxy, the Foreman host group is available as a parameter in FreeIPA known as userclass
. Nested host groups are sent as displayed in the Foreman UI, e.g. “Parent/Child/Child”. Note that Foreman does send updates to FreeIPA, however automember rules are only applied at initial add. This will be coming in a future version of FreeIPA.
First, we create a host group in FreeIPA:
# ipa hostgroup-add webservers
Description: web servers
----------------------------
Added hostgroup "webservers"
----------------------------
Host-group: webservers
Description: web servers
Define an automember rule:
# ipa automember-add --type=hostgroup webservers
----------------------------------
Added automember rule "webservers"
----------------------------------
Automember Rule: webservers
Create an automember condition based on the userclass
attribute:
# ipa automember-add-condition --key=userclass --type=hostgroup --inclusive-regex=^webserver webservers
----------------------------------
Added condition(s) to "webservers"
----------------------------------
Automember Rule: webservers
Inclusive Regex: userclass=^webserver
----------------------------
Number of conditions added 1
----------------------------
When a machine in Foreman is in the “webservers” host group, it will automatically be added to the FreeIPA “webservers” host group as well. FreeIPA host groups allow for Host-based access controls (HBAC), sudo policies, etc.
Activate the TFTP management module within the Smart Proxy instance. This is designed to manage files on a TFTP server, e.g. bootloaders for OS installation and PXE menu files.
The tftproot value is directory into which TFTP files are copied and then served from. The TFTP daemon will also be expected to chroot to this location. This component is only supported in a Unix environment.
:enabled: https
:tftproot: /var/lib/tftpboot
:tftp_servername: name of your tftp server (used for next server value in your dhcp reservation) - defaults to the host name of your proxy.
An essential first step in netbooting a system is preparing the TFTP server with the PXE configuration file and boot images. This document assumes that you have already configured your DHCP infrastructure, either via manual configuration or through the DHCP smart proxy.
Regardless of the filesystem setup is performed, you must also make sure you have the wget utility installed and in the default path. wget is used to download OS specific installation when a given host is enabled for the build process.
Foreman includes a TFTP server module that will perform all of the basic setup. It defaults to TFTP root of /var/lib/tftpboot, which may change if necessary. You will still need to provide the basic TFTP load images in your TFTP root directory. For vanilla PXE booting via PXELinux, this includes pxelinux.0, menu.c32, and chain.c32, for PXEGrub this includes grub2/ and grub/ subdirectories.
The setup is very simple, and may be performed manually if desired.
In most cases, the default templates should work fine. You do, however, need to make sure that a PXELinux or iPXE template is associated with your hosts. See Using PXE to Provision Hosts for details. The template will be used to define the PXE configuration file when a host is enabled for build.
This is a rough outline of the steps triggered on the TFTP smart proxy host when you click on the “Build” link for a host.
wget --no-check-certificate -nv -c <src> -O "<destination>"
To make sure that you trigger the above workflow make sure you’ve satisfied these requirements:
At the moment, the proxy is not able to fetch boot files using NFS. As a workaround, expose your installation medium (or use a public mirror) over http/ftp to configure one machine with the require boot files. this would be resolved as part of #992.
You can build PXE default on TFTP proxy from Foreman UI from ‘Provisioning Templates’ page using ‘Build PXE Default’ button. You also have the ability to choose which templates are used for this action. Foreman exposes the following settings in the ‘Provisioning’ group for this purpose: Global default PXEGrub template, Global default PXEGrub2 template and Global default PXELinux template. When settings are empty, Foreman uses default values: PXELinux global default, PXEGrub global default and PXEGrub2 global default.
The smart proxy can work in SSL mode, where both sides verify and trust each other. Requests from Foreman will only be accepted if the SSL certificate can be verified. Since proxies abstract a high level of control over your infrastructure, the configuration and security of keys and certificates is important.
Since Foreman integrates with Puppet heavily, it is recommended to use the Puppet Certificate Authority (CA) to secure proxy access. See the Security Communciations with SSL section for more advanced installations (multiple or internal CAs).
If the smart proxy host is not managed by Puppet, you will need to generate a certificate - skip forward to the generate section.
When using Puppet’s certificates, the following lines will be required in puppet.conf to relax permissions to the puppet
group. The foreman
and/or foreman-proxy
users should then be added to the puppet
group.
[main]
privatekeydir = $ssldir/private_keys { group = service }
hostprivkey = $privatekeydir/$certname.pem { mode = 640 }
Configure the locations to the SSL files in /etc/foreman-proxy/settings.yml
, plus the list of trusted Foreman hosts:
:ssl_certificate: /etc/puppetlabs/puppet/ssl/certs/FQDN.pem
:ssl_ca_file: /etc/puppetlabs/puppet/ssl/certs/ca.pem
:ssl_private_key: /etc/puppetlabs/puppet/ssl/private_keys/FQDN.pem
:trusted_hosts:
- foreman.corp.com
#- foreman.dev.domain
By default, the smart proxy permits the following SSL cipher suites:
Please note, the smart proxy uses the OpenSSL suite naming scheme. For more information on suite names please see the OpenSSL docs.
Certain users may require to disable certain cipher suites due to security policies or newly discovered weaknesses. This can be done by using the :ssl_disabled_ciphers:
option in /etc/foreman-proxy/settings.yml
. For example:
:ssl_disabled_ciphers: ['AES128-SHA','AES256-SHA']
To generate a certificate for a proxy host that isn’t managed by Puppet, do the following:
puppet cert --generate <proxy-FQDN>
/etc/foreman-proxy
:
Follow the configuration section above, however use the /etc/foreman-proxy
paths instead of the Puppet defaults.
For Foreman to connect to an SSL-enabled smart proxy, it needs configuring with SSL certificates in the same way. If the Foreman system is managed by Puppet, it will already have these, else certificates can be generated following the above instructions.
The locations of the certificates are managed in the Settings page, under Provisioning with the ssl_ca_file, ssl_certificate and ssl_priv_key settings. By default these will point to the Puppet locations - for manually generated certificates, or non-standard locations, they may have to be changed.
Lastly, when adding the smart proxy in Foreman, ensure the URL begins with https://
rather than http://
.
In this chapter, we will describe how to setup DHCP and DNS for use with the libvirt provider for dnsmasq.
This provider is able to change DHCP and DNS settings in libvirt with dnsmasq. The smart proxy directly connects to the libvirt daemon.
The provider is currently limited by the libvirt API which does not provide PTR records creation via the API itself, but dnsmasq automatically creates PTR record for the first A/AAAA entry. Therefore PTR lookups do work in the network, but it is not being created by Foreman orchestration.
The provider also returns active leases on systems with ruby-libvirt
gem
version 0.6.1 or higher.
Define the TFTP root first. Edit ‘default’ virtual network and add ‘tftp’, ‘bootp’ and ‘domain’ elements.
<network>
<name>default</name>
<uuid>16b7b280-7462-428c-a65c-5753b84c7545</uuid>
<forward mode='nat'/>
<bridge name='virbr0' stp='on' delay='0' />
<domain name="local.lan"/>
<dns>
</dns>
<mac address='52:54:00:a6:01:5d'/>
<ip address='192.168.122.1' netmask='255.255.255.0'>
<tftp root='/var/tftproot' />
<dhcp>
<range start='192.168.122.2' end='192.168.122.254' />
<bootp file='pxelinux.0' />
</dhcp>
</ip>
</network>
Create a TFTP root directory, make sure it is writeable by the foreman proxy
user (foreman-proxy
for instance) and accessible to the account
dnsmasq is running on (in Fedora this is nobody
), set gid flag for newly
copied files and copy necessary files to the new TFTP root directory:
mkdir -p /var/tftproot/{boot,pxelinux.cfg}
yum -y install syslinux
cp /usr/share/syslinux/{pxelinux.0,menu.c32,chain.c32} /var/tftproot
chown -R foreman-proxy:nobody /var/tftproot
find /var/tftproot/ -type d | xargs chmod g+s
Open up /etc/libvirt/libvirtd.conf
file and configure foreman-proxy
user
to be able to connect to libvirt daemon:
unix_sock_group = "foreman-proxy"
unix_sock_rw_perms = "0770"
Alternatively (on development setups), you can turn off authentication:
auth_unix_rw = "none"
Configure the Smart Proxy settings under config/ to:
default
on local libvirt daemon instance)Important configuration values are, in tftp.yml
:
:tftp: true
:tftproot: /var/tftproot
:tftp_servername: 192.168.122.1
in dns.yml
:
:enabled: true
:use_provider: dns_libvirt
in dhcp.yml
:
:enabled: true
:use_provider: dhcp_libvirt
and in dns_libvirt.yml
and/or dhcp_libvirt.yml
:
:network: default
:url: qemu:///system
Make sure the DNS server is configured with the foreman instance by setting
/etc/resolv.conf
file or changing this in NetworkManager or dnsmasq
configuration. Example:
cat /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 192.168.122.1
Foreman is now configured for libvirt provisioning, this is the recommended setup for git development checkouts.
In this chapter, we will describe how to setup a Smart Proxy to serve provisioning templates.
The smart proxy is able to proxy template requests from hosts in isolated networks to the Foreman server, when the proxy also handles TFTP.
This feature relies on correctly configured trusted_proxies on Foreman.
Ensure the foreman_url in /etc/foreman-proxy/settings.yaml
points to your Foreman instance, and that your smart proxy is listening on HTTP by uncommenting http_port
. Now
configure /etc/foreman-proxy/settings.d/templates.yml
:
:enabled: true
:template_url: http://smart-proxy.example.com:8000
Once you’ve completed the above steps, restart the foreman-proxy service and refresh the features on your Foreman server.
The templates feature is used automatically: any host that uses this proxy for TFTP will also use the proxy to retrieve its templates.
The smart proxy’s logs module provides an API to retrieve recently logged messages and information about failed modules. This will be displayed in Foreman under the Smart Proxy pages when the module is enabled.
The module has no configuration options of its own, and is just enabled by configuring /etc/foreman-proxy/settings.d/logs.yml
:
:enabled: https
Once enabled, restart the foreman-proxy service and refresh the features on your Foreman server.
The number of logs is controlled by the main smart proxy logging settings, detailed in Smart Proxy Settings.
This chapter details the configuration of the required UI components necessary to provision an OS onto a host.
The Operating Systems page (Hosts -> Provisioning Setup -> Operating Systems) details the OSs known to Foreman, and is the central point that the other required components tie into.
Simply click Create Operating System on the main page. You will be taken to a screen where you can create the bare essentials of a new OS. Not everything required for a successful provision is on this page (yet) - the remaining components will appear for selection as we create them.
You will need to fill in the first few parts of the form (Name, Major, Minor, Family, and possibly some family-dependent information). In the case of OSs like Fedora, it is fine to leave Minor blank.
If the default Partition Tables & Installation media are suitable, then you can assign them now. If not, return here after each step in this chapter to assign the newly created objects to your Operating System
Foreman does not come with any Operating Systems by default. However, Foreman will detect the Operating System of any host which reports in via Puppet - if the OS of that Host is supported, it will be created (with very basic settings) and assigned to the Host. Thus you may find some OSs already created for you.
The Installation Media represents the web URL from where the installation packages can be retrieved (i.e. the OS mirror). Some OS Media is pre-created for you when Foreman is first installed. However, it is best to edit the media you are going to use and ensure the Family is set.
If your OS of choice does not have a mirror pre-created for you, click the New Medium button to create one. There are a few variables which can be used to pad out the URL. For example:
http://mirror.averse.net/centos/$major.$minor/os/$arch
Be sure to set the Family for the Media
If you have not already done so, return to the Operating System page for your OS and assign the Media to it now.
Provisioning Templates are the core of Foreman’s flexibility to deploy the right code or options to the right OS. There are several types of template, along with a flexible matching system to deliver different templates to different Hosts.
Foreman comes with pre-created templates for the more common OSs, but you will need to review these. All these templates are locked by default, hence they can not be modified. Most of them are customizable through parameters, but if you need some custom functionality, the recommended workflow is to clone the template and edit the clone. You can unlock the pre-created template and edit it directly, but note that any custom change will be overridden on any Foreman update. If you believe your change is worthy of inclusion in next Foreman release, please consider sending a patch to foreman repository’s templates via the normal contribution process.
There are several template kinds:
In practice, most environments only make use of the first 3. The Create Host action deploys the PXELinux template to the TFTP server. The PXELinux template directs the host to retrieve the Provision template. The Provision template will direct the installer to retrieve and run the Finish template at the end of the install, and the Finish template will notify Foreman the build is complete just before reboot.
Unlocked templates can be edited from the Hosts > Provisioning templates menu, or from an existing host page under its Templates tab (which shows the templates in use).
The templates use the ERB (Embedded Ruby) templating language, allowing data from the host in Foreman to be added to the template output and for conditional content. The default templates make heavy use of the ERB feature, adding and changing the template behavior based on parameters, the operating system, or the networking configuration assigned to the host.
There are two general types of ERB syntax in templates. The <%=
prefix outputs the value of the following expression into the rendered template, e.g. to output the hostname:
<%= @host.name %>
The <%
prefix without the equals sign (=
) is a general code block that may contain conditionals, variable assignments, or loops which are not output when rendered. Comments may also be in these blocks, prefixed with #
.
<%
a_variable = @host.name
%>
<%= a_variable %>
Other examples of ERB syntax are given on the Help tab of the template editor, and many more examples are available on the Template Writing Reference. The Help tab also lists available Global methods (functions) provided by Foreman such as foreman_url
(the URL for unattended calls to Foreman), and template_name
.
The methods available on the provided @host
variable are limited by default (when safemode_render
is enabled) to prevent exploitation of Foreman through templates. The permitted methods on all types of objects can be found in the Safe mode methods and variables table under the Help tab.
As noted in section 4.1.4 Auditing, changes to the templates are logged as diffs - you can browse the history of changes to the templates from the History tab within the Edit Template page. You can also revert changes here.
When editing a Template, you must assign a list of Operating Systems which this Template can be used with. Optionally, you can restrict a template to a list of Hostgroups and/or Environments
When a Host requests a template (e.g. during provisioning), Foreman will select the best match from the available templates of that type, in the following order:
The final entry, Operating System default, can be set by editing the Operating System page.
You will need to associate at least one PXE, Provision, and Finish template to your Operating System, and this must be done in two steps. First edit each of the templates, switch to the Association tab, and ensure the appropriate OSs are checked. Then edit the Operating System, switch to the Templates tab, and choose a default template for each template kind.
More than one PXE template can be associated. In this case, all associated PXE templates are deployed to the TFTP server and only one is picked up during provisioning according to the PXE Loader setting (see below).
For image based installs there are two methods to customize and finish the installation. Finish templates and User Data templates:
Finish templates are available for all hypervisors that support image based installs where the foreman server can reach the newly installed machine via ssh and scp. The script generated from the finish template is copied by the Foreman to the newly installed system via scp using username and password specified with the image. It is then executed by connecting again via ssh, making the script executable and either executing it directly or via sudo if the specified user is not root. Standard output and standard error are logged to a file in the same directory named bootstrap-UUID.log.
User Data Templates are available for hypervisors that support customization via tools like cloud-init. In this case the installed machine does not need be reachable via ssh by the Foreman server. However, the installed must be able to reach Foreman or a Smart Proxy with the templates feature via http(s) to notify the setup has finished.
When creating a new Host, the PXE Loader option must be selected in order to pass the correct DHCP filename option to the client. One option out of the following must be chosen:
pxelinux.0
filename from TFTP)pxelinux.efi
filename from TFTP)grub/bootx64.efi
filename from TFTP)grub/shim.efi
filename from TFTP)grub2/grubx64.efi
filename from TFTP)grub2/shim.efi
filename from TFTP)Grub filenames are different for each individual architecture associated with the Host:
grub/bootia32.efi
(for Intel named "i*86" where * can be any character)grub/bootx64.efi
(for Intel named "x86-64")grub2/grubia32.efi
(for Intel named "i*86" where * can be any character)grub2/grubx64.efi
(for Intel named "x86-64")grub2/grubaa64.efi
(for ARM 64 named either "aa64" or "aarch64")grub2/grubppc64.efi
(for IBM POWER named "ppc64”)grub2/grubppc64le.efi
(for IBM POWER Little Endian named "ppc64le")grub2/grubXYZ.efi
(for arbitrary Architecture named "XYZ")Foreman installer only installs pxelinux.0
and grub2/grubx64.efi
(if grub2
is available). In order to boot systems via other loaders like PXELinux EFI or
Grub 1 (legacy), deploy the required bootloader files in the TFTP directory.
Some operating systems use a “shim” loader for SecureBoot (e.g. Red Hat
Enterprise Linux and clones). To use SecureBoot with an operating system that
does not use a shim chainloader, make a copy of the signed EFI loader named
shim.efi
or make a symlink in order to do secure boot.
Partition templates are a subset of normal Provisioning Templates. They are handled separately because it is frequently the case that an admin wants to deploy the same host template (packages, services, etc) with just a different harddisk layout to account for different servers’ capabilities.
Foreman comes with pre-created templates for common Operating Systems, but it is good to edit the template, check it’s content and it’s Family setting. If the Family is wrong, be sure to go back to Operating Systems and associate it with your Operating System.
When creating a new Host, you will be given the option to create an individual partition table. This is essentially a ‘one-off’ partition table that is stored with the host and used only for that host. It replaces the choice of Partition Table from the normal list of those associated with the selected OS.
Some operating systems allow you to create partition tables via scripts. At the moment Kickstart and AutoYaST based systems can use this feature. Partition templates starting with #Dynamic
are interpreted as scripts rather than static partition tables. The Provisioning Template needs to support this feature (search for @dynamic
). This enables you to make choices on the fly during provisioning (or re-provisioning).
Kickstart will run dynamic partition tables as a pre-install bash script using a %pre scriplet. This script needs to create a complete Kickstart partition table in ‘/tmp/diskpart.cfg’. This partition table will then be read by anaconda for the installation by using %include /tmp/diskpart.cfg
.
Example Dynamic Partition table:
#Dynamic - this line tells Foreman this is a script rather then a static layout
#This snippets define the swap partition size, it would generate a partition twice the size of the memory if your physical memory is up to 2GB
#or will create a swap partition with your memory size + 2GB.
#get the actual memory installed on the system and divide by 1024 to get it in MB
act_mem=$((`grep MemTotal: /proc/meminfo | sed 's/^MemTotal: *//'|sed 's/ .*//'` / 1024))
#check if the memory is less than 2GB then swap is double the memory else it is memory plus 2 GB
if [ "$act_mem" -gt 2048 ]; then
vir_mem=$(($act_mem + 2048))
else
vir_mem=$(($act_mem * 2))
fi
#copy all the HDD partitions to the temp file for execution
cat <<EOF > /tmp/diskpart.cfg
zerombr yes
clearpart --all --initlabel
part swap --size "$vir_mem"
part /boot --fstype ext3 --size 100 --asprimary
part / --fstype ext3 --size 1024 --grow
EOF
AutoYaST will run dynamic partition tables as a pre-install bash script. This script needs to create a AutoYaST XML file in /tmp/profile/modified.xml
. The modified.xml file will be read by YaST after your script has finished. An example for getting the same functionality as with Kickstart would be to create your XML partition table in /tmp/diskpart.cfg
and sed it together with the original AutoYaST XML like this: sed '/<\/ntp-client>/ r /tmp/diskpart.cfg' /tmp/profile/autoinst.xml > /tmp/profile/modified.xml
. Inserting after ntp-client section is just a suggestion that uses the same style the community-templates do. The example uses a simplified version of the AutoYaST LVM Partition table template.
Example Dynamic Partition table:
#Dynamic - this line tells Foreman this is a script rather then a static layout
#This snippets define the swap partition size, it would generate a partition twice the size of the memory if your physical memory is up to 2GB
#or will create a swap partition with your memory size + 2GB.

#check if the memory is less than 2GB then swap is double the memory else it is memory plus 2 GB
if [ "$act_mem" -gt 2048 ]; then
vir_mem=$(($act_mem + 2048))

The inclusion of the keyword string #Dynamic
at the start of a line lets Foreman know that this is not an explicit
disk layout and must treated as a shell script, executed prior to the install process and that the explicit partition
table will be found at /tmp/diskpart.cfg
during the build process.
The dynamic partitioning style is currently only available for the Red Hat family of operating systems, all others must provide an explicit list of partitions and sizes.
You may also associate one or more operating systems with this partition table or alternatively set this up later on the Operating systems page.
Architectures are simple objects, usually created by Foreman automatically when Hosts check in via Puppet. However, none are created by default, so you may need to create them if you’re not using Foreman for reporting.
Simply click New Architecture to create a new one. This should match the Facter fact :architecture e.g. “x86_64”. If you’ve already created some Operating Systems, you can associate the Architecture with the OS now; if not, the list of Architectures will be present when you create an OS.
Foreman performs a number of orchestration steps when performing unattended installation or provisioning, which vary depending on the integration options chosen - e.g. use of compute resources, configuration management tool and provisioning method (network/PXE/image).
The following example uses:
This example shows workflow of cloud-based provisioning on IaaS (e.g. OpenStack) via cloud-init which configures Puppet agent to finish off the configuration.
This example shows workflow of cloud-based provisioning on IaaS (e.g. OpenStack) via ssh finish template for Puppet agent configuration.
This example shows workflow of image-based provisioning on virtualization (e.g. oVirt, RHEV or VMware via ssh finish template for Puppet agent configuration.
This example shows workflow of PXE booting into Anaconda installer with Puppet agent configuration.
Foreman can store information about the networking setup of a host that it’s provisioning, which can be used to configure the virtual machine, assign the correct IP addresses and network resources, then configure the OS correctly during the provisioning process.
This section details the options available for network interfaces in the New Host form and how they’re used.
A simple, single-homed host would have one network interface with a DNS name set matching the hostname, then managed, primary and provision flags all ticked. This would create one interface with DNS and DHCP records (if configured) over which the OS would be set up.
A dual or multi-homed host could have one interface with primary enabled (“host.example.com”) and another network with provision enabled (“host-build.example.com”). If both are also managed, Foreman will create DNS and DHCP records for both, but on the provision interface, the next-server/filename options for PXE will also be set. A TFTP (PXELinux) menu would also be created for the provision interface’s MAC address so the host can PXE boot on that physical interface, while its hostname would be assigned from the primary interface.
When Foreman deploys a host onto a compute resource, it creates a new interface on the VM for each interface specified when creating the host.
After creation, Foreman reads back the network information and matches the created interfaces to the list of interfaces given for the host and stores the assigned MAC and IP addresses (depending on the compute resource type) in its database. It then continues with orchestration, creating DNS and DHCP records etc. for the addresses retrieved from the new VM. Once orchestration of these is complete, it powers up the VM.
This design alleviates the need to supply MAC addresses for hosts being created on compute resources.
Subnets are defined in Foreman under Infrastructure > Subnets, and have a few options that affect how hosts are provisioned.
Various combinations of the IPAM and Boot mode settings make sense, but the most common are DHCP (IPAM) with DHCP (Boot mode) and Internal DB with Static.
Provisioning templates (such as kickstart, preseed or finish scripts) can make use of the interfaces data stored in Foreman for the host to configure the network.
A snippet (“kickstart_networking_setup”) is supplied by default in Foreman for kickstart-based OSes, which configures all managed network interfaces after the main OS installation is complete. This can be used in the %post kickstart section. No template is currently available for preseed-based OSes (ticket)
A hash of interfaces data is also made available to Puppet via a global ENC parameter called “foreman_interfaces”. This can be used to fully configure the network from a Puppet run.
This chapter contains information about provisioning specific operating systems.
As the FreeBSD installer itself does not support a kickstart-like pulling of a response file, a custom mfsBSD image with zfsinstall is used. Prebuilt images are available for download to be placed into the boot directory of your TFTP server.
However, these images can also be built from scratch as described below:
This is an example how to build an image for FreeBSD 10.2-RELEASE. For other releases, simply replace the version accordingly.
# fetch the necessary FreeBSD components
mkdir /tmp/basefiles
cd /tmp/basefiles
fetch ftp://ftp.freebsd.org/FreeBSD/releases/amd64/10.2-RELEASE/base.txz
fetch ftp://ftp.freebsd.org/FreeBSD/releases/amd64/10.2-RELEASE/kernel.txz
# clone the git repository
git clone https://github.com/theforeman/mfsbsd.git
cd mfsbsd
# build the image (you need to be root for this to succeed)
make BASE=/tmp/basefiles RELEASE=10.2-RELEASE ARCH=amd64
# copy the image into the TFTP server directory
cp mfsbsd-10.2-RELEASE-amd64.img /tftpboot/boot/FreeBSD-x86_64-10.2-mfs.img
The installation media URL has to contain the contents of the first SLES DVD, it’s easiest to loopback mount the ISO image on a webserver. For Puppet, the systemsmanagement:puppet
repository on OBS is used.
For Puppet, in addition to systemsmanagement:puppet
also the devel:languages:ruby:backports
repository on OBS and the SLES SDK DVD is used. The placeholder in the AutoYaST SLES template has to be updated with the actual SDK URL.
Provisioning Windows is a two step process. The first step, creating Installation Media, is not discussed here. It includes getting the WIM files, updates and drivers and boot files ready. The necessary boot files are are later downloaded by automatically by the smart proxy.
In Hosts > Architectures add a new architecture:
x64
Add a new OS in Hosts > Operating systems if needed. If you already have Windows hosts and with Puppet installed, the correct OS and architecture will have been auto created already. This example covers Windows 8.1 / Windows Server 2012R2.
windows

windows
Windows8
Base64
x64
Take special care to set Root password hash = Base64
. The templates do not render correctly if this is set otherwise.
Changing the encoding does not apply to existing hosts.
Note: Foreman’s Safe Mode does prevent using the password directly.
Thus, the string AdminPassword
needs to be appended to your password when adding a new host. Eg P@55w0rd
would become P@55w0rdAdminPassword
.
This can be automated however by replacing the password part with a ruby function and disabling safe mode render.
Head to Hosts > Provisioning Templates and edit the templates starting with WAIK
to meet your needs. Make sure to get the latest version of the WAIK templates from the community templates project.
Assign each of those templates to your Windows OS (does not apply to snippets).
The naming of the templates is a suggestion and up to you. This does not apply to snippets! There, the name is important.
Note: You can find more info about Foreman Template Writing in the documentation.
WAIK Finish

WAIK unattend.xml
WAIK unattend.xml
WAIK peSetup.cmd
WAIK peSetup.cmd
Note: To get the download folders nicely, the wget
commands in this template might need tweaking. This could
especially be necessary if you intend to use the extraFinishCommands
snippet.
Eg, --cut-dirs=3
would cut the first three directories form the download path when saving locally.
This way http://winmirror.domain.com/pub/win81x64/extras/puppet.msi
will be stripped of pub/win81x64/extras
and download to puppet.msi
.

Note: This snippet creates extra users in the unattended stage. This may be very useful for debugging early stages of your deployment; since you can find yourself locked out of the newly provisioned host.
Microsoft does not really care about password security in unattend.xml files; so it does not really matter if you use
<PlainText>true</PlainText>
or not. If you prefer the encoded form, you need to append the string Password
to your user password and encode it to Base64. The following ruby function is an example, it creates the encoded from of P@55w0rd
:
Base64.encode64(Encoding::Converter.new("UTF-8", "UTF-16LE",:undef => nil).convert("P@55w0rd"+"Password")).delete!("\n").chomp
WAIK extraFinishCommands
WAIK extraFinishCommands
Note: The commands here are executed at the last stage just before finishing host building. Make sure they get executed in a synchronous way (eg. do not run in background like msiexec). Otherwise the following reboot might kill them.
WAIK OU from host group
WAIK OU from host group
Note: This snippet may be used to generate the computer OU from the host’s host group and domain.
Example: Given a host example
in domain ad.corp.com
and in host group servers/windows/databases
.
The snippet generates the OU path:
OU=databases,OU=windows,OU=servers,DC=ad,DC=corp,DC=com
. Optionally, set the host parameter computerOuSuffix
to add some arbitrary OU at the end.
For each of your Windows versions add a new installation medium pointing to the root of the folder containing boot and sources
Eg, http://winmirror.domain.com/pub/win81x64
. Assign them to your operating system.
The default partition table is a simple diskpart.exe
script. It will wipe Disk 0
Link all the created templates as well as the installation media and partition table to the OS:

To render the templates correctly, some parameters need to be added. They need to be available as global/host parameters. Most of them make the most sense as parameter on the OS. Most parameters are not required and have defaults. For the most up to date description see the template itself.

The templates most likely need a lot of testing to work. This is not covered here; though some hints how to start. You should proceed in this order:
Bare Metal
host in the desired host group for this purpose and make extensive use of Foreman’s template preview feature.peSetup.cmd
by pausing it at the send (remove the comment from ::PAUSE
). Then, use Ctrl-C
to cancel the script altogether. This way you can debug the rendered peSetup.cmd
quite nicely in WinPE (eg, notepad peSetup.cmd
)WAIK Finish
template uses sDelete.exe
to remove all rendered commands from the provided host. Comment out all sDelete
commands to debug finish scripts.WAIK extraFinishCommands
directly.C:\foreman.log.
- the output left from the finish script. Also, comment out the clean up stage in the finish script to examine and test the rendered scripts directly.Netbooting
Sometimes wimboot seems not to be able to boot our winPE.wim. Symptoms range from black screens to kernel panics (aka BSOD). These problems seem to be more likely on older hardware.
In this case a workaround can be to simply use any other bootable media like USB thumb drives and CD-ROMs. The process is relatively simple:
architecture
.sources/boot.wim
with the version from the installation media.The framework used for implementation of command line client for foreman provides many features common for modern CLI applications. The task of managing Foreman from command line is quite complex so the commands have to be organized in more levels of subcommands. There is help available for each level to make it easy to use. Some other features for greater comfort are option validation, logging and customizable output formatting.
Basic help and list of supported commands:

There was a set of common commands identified as necessary for basic Foreman management, we called it “success story” and track the progress of its implementation. The commands could also serve as a basic hammer cookbook.

Foreman is also able to send out a variety of email notifications either on an event, or summary messages on a regular schedule. Plugins are also able to extend this with their own summaries and notifications.
To send email requires a configured SMTP server or local MTA (e.g. sendmail), which is set up in Adminster > Settings > Email
as per Configuration Options.
Scheduled emails are sent through rake tasks (reports:daily, reports:weekly, reports:monthly) run from cronjobs, which are configured in /etc/cron.d/foreman
.
Email messages are sent to individual users registered to Foreman, to the email address configured on the account if present. Users can edit the email address by clicking on their name in the top-right hand corner of the web page and selecting My account.
To change which message subscriptions are received by an individual user, the Mail Preferences tab under the user account lists all available message types and the frequency at which each message should be received. A global checkbox to disable all email messages from Foreman is also available.
Event-based notifications can either be enabled or disabled, and these are sent from Foreman at the same time as the event occurring. Scheduled notifications can be sent either daily, weekly or monthly.
Notifications relating to hosts can be disabled on a per-host basis, useful when errors are expected. On the host’s Additional Information tab, untick Enabled to disable notifications and remove the host from reports. Enabling and disabling notifications can also be done from the host list by using the tickboxes and selecting Enable/Disable Notifications from the Select Action dropdown menu.
Event notifications for a host are sent to the host’s registered owner. This is selected on the Additional Information tab of the host, and may be either an individual user or a user group. When set to a user group, all group members who are subscribed to the email type will receive a message.
When the send_welcome_email
setting is enabled (Configuration Options), new account holders will receive an email providing their username and a link to Foreman.
When a host has completed its build process, either notifying Foreman of completion via a request at the end of its unattended installation or after Foreman has run a script remotely, this email notification will be sent to owners of the host.
When a Puppet report is received that puts the host into a red error state, a corresponding email notification is sent to owners of the host.
A regular summary email of all changes to objects in Foreman that triggered audit events (see Auditing), including the user that made the change, the time of the change and a link to further details.
A regular overview of all hosts that a user has access to, and their Puppet status. This includes the number of Puppet events over the reporting period, such as applied, skipped and failed resources.
Please refer to the foreman_ansible plugin documentation.
The foreman_chef
plugin has been removed.
Documentation: Using Salt for Configuration Management
To monitor your infrastructure, host statuses are useful. In Foreman each host has a global status that indicates which hosts need attention. Each host also has sub-statuses that represents status of a particular feature. With any change of a sub-status, the global status is recalculated and the result is determined by statuses of all sub-statuses.
The global status represents the overall status of a particular host. The status can have one of three possible values - OK, Warning or Error.
OK means that no errors were reported by any sub-status. It is represented with the color green.
Warning suggests that user should verify the status, while no error was detected, some sub-status raised a warning. A good example would be that there are no Puppet reports for the host even though the host is configured to send Puppet reports. Therefore it is highlighted with the color yellow.
The last possible value is Error which indicates that some sub-status reports a failure. This could for example mean that Puppet run contains some failed resources. Obviously it is something that should be fixed and is user is alerted by the color red.
You can find global status on hosts overview page displayed as a small icon next to host name with corresponding color. Hovering over the icon renders a tooltip with sub-status information to quickly find out more details.
A sub-status monitors only a part of host capabilities. Currently Foreman ships only two - build and configuration sub-statuses. Not all sub-statuses are relevant for all hosts, therefore configuration is only considered if host is using some configuration management system, e.g. has some Puppet proxy associated. Build sub-status is relevant for managed hosts and when Foreman is run in unattended mode.
You can see a global host status with all sub-statuses on the host detail page, in the properties table. Note that there can be more sub-statuses added by plugins.
Each sub-status can define own set of possible values that are mapped to three global status values. Build sub-status has two possible values - pending and built that are both mapped to global OK value. Configuration status is more complicated and its possible values and mappings are described in table below.
Status value | Maps to | Description |
---|---|---|
Error | Error | Error during configuration, e.g. Puppet run failed to install some package |
Out of sync | Warning | A configuration report was not received within the expected interval, based on the outofsync_interval1 |
No reports | Warning / OK | When there are no reports but the host uses configuration management system (e.g. Puppet proxy is associated) or always_show_configuration_status setting is set to true, it maps to Warning. Otherwise it is mapped to OK. |
Active | OK | During last Puppet run, some resources were applied |
Pending | OK | During last Puppet run, some resources would be applied but Puppet was configured to run in noop mode |
No changes | OK | During last Puppet run, nothing has changed |
1 Reports are identified by an origin and can have different intervals based upon it. For example, reports by Puppet will have ‘Puppet’ as it’s origin and will have it’s interval set by puppet_interval.
You can search hosts by global status. Some examples can be found below:
search for all hosts that are OK
global_status = ok
search for all hosts that deserves some attention
global_status = error or global_status = warning
To search hosts based on configuration status you can search by last report metrics like this:
find hosts that have at least one pending resource
status.pending > 0
find hosts that restarted some service during last puppet run
status.restarted > 0
find hosts that have an interesting last Puppet run (something happened)
status.interesting = true
Foreman provides reporting capabilities. It uses the same templating engine as for provisioning templates and partition tables. The list of macros that can be used in this context slightly differs as reports are usually rendered for a specific host. Reports do not enforce any output format as the formatting is part of the template itself, the only requirement is, that the resulting output is textual form.
You can find existing report templates under Monitor -> Report Templates. Foreman comes with few default report templates that are locked. As with other templates, we do not recommend unlocking and modifying them, as they are automatically updated on upgrades. If a change of default template is desired, it’s recommended to clone the template and do adjustments in the clone.
To generate a report out of the report template, find the report template and click the Generate button. This will evaluate a template and respond with text file for download. The rendering itself is done in a background process, but it can run for a long time.
There’s a separate permission for generating the report, so only selected users can perform resource heavy operations while another users can prepare the report templates.
In the form for report generating you can choose a starting time for delayed rendering. There is no way to schedule repetitions, but as the report generating can be started by a hammer report-template command, scheduling can be achieved using cron. For these planned reports, as well as for long running reports, it is no longer useful to have the report downloaded by the web browser. In such cases you can choose to get the report delivered via e-mail by simply checking Send report via e-mail and filling the e-mail addresses field. Your default e-mail address is prefilled, but you can fill other(s) and send reports for further processing.
For report templates, it’s useful to access more data from database than in regular provisioning templates. Typically it’s needed to load all hosts matching some search query. If safe mode rendering is enabled, access to internal objects is restricted. Foreman provides resource loading macros such as load_hosts. They all have following behaviors and capabilities:
Consider following example:
<%- load_hosts(search: 'name ~ example.com').each_record do |host| -%>
<%= host.name %>,<%= host.mac %>
<%- end -%>
It loads all hosts that contains domain example.com in their name. If it’s more than 1,000 hosts, it will trigger separate SQL query for each thousand automatically. Then it iterates over all found hosts and print comma separated pair of host name and MAC address. The query will return only hosts that current user has view_hosts permission for.

API v2 is the default, stable and recommended version for Foreman 3.10. Foreman 1.22 and above also provides a GraphQL API. This API is considered experimental for now. Please test it and provide feedback, we do not recommend it for production use just yet.
This section documents the JSON API conventions for the Foreman API v2 and Katello API v2. To explicitly select the API version, see Section 5.1.6.
The following examples show the basic CRUD operations (Create, Read, Update, Delete) using the JSON API.
Get of a collection of domains: GET /api/domains
Send a HTTP GET request. No JSON data hash is required.
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" https://foreman.example.com/api/domains
This returns a collection JSON response. The format for a collection response is described in Section 5.1.2.
Get a single domain: GET /api/domains/:id
or GET /api/domains/:name
Send a HTTP GET request with the object’s unique identifier, either :id
or :name
. No JSON data hash is required.
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" \
https://foreman.example.com/api/domains/42
# or
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" \
https://foreman.example.com/api/domains/foo
This returns a single object in JSON format. The format for a single object response is described in Section 5.1.3.
Create a new domain: POST /api/domains
Send a HTTP POST request with a JSON data hash containing the required fields to create the object. In this example, a domain is being created.
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" -H "Content-Type: application/json" \
-X POST -d '{ "name":"foo.bar.com","fullname":"foo.bar.com description" }' \
https://foreman.example.com/api/domains
This returns the newly created object in JSON format, with the same attributes as in the show/GET call. The format for a single object response is described in Section 5.1.3.
The HTTP response code of the create call will be 201, if created successfully.
Update a domain: PUT /api/domains/:id
or PUT /api/domains/:name
Send a HTTP PUT request with the object’s unique identifier, either :id
or :name
, plus a JSON data hash containing only the data to be updated. In this example, only the domain name is being updated.
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" -H "Content-Type: application/json" \
-X PUT -d '{ "name": "a new name" }' https://foreman.example.com/api/domains/12
# or
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" -H "Content-Type: application/json" \
-X PUT -d '{ "name": "a new name" }' https://foreman.example.com/api/domains/foo
This returns the newly updated object in JSON format. The format for a single object response is described in Section 5.1.3.
Delete a domain: DELETE /api/domains/:id
or DELETE /api/domains/:name
Send a HTTP DELETE request with the object’s unique identifier, either :id
or :name
. No JSON data hash is required.
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" -X DELETE \
https://foreman.example.com/api/domains/17
# or
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" -X DELETE \
https://foreman.example.com/api/domains/foo
This returns the deleted object in JSON format. The format for a single object response is described in Section 5.1.3.
Collections are a list of objects (i.e. hosts, domains, etc). The format for a collection JSON response consists of a results
root node and metadata fields total, subtotal, page, per_page
. Note: for Katello objects, the metadata includes limit, offset
instead of page, per_page
.
Below is an example of the format for a collection JSON response for a list of domains: GET /api/domains
{
"total": 3,
"subtotal": 3,
"page": 1,
"per_page": 20,
"search": null,
"sort": {
"by": null,
"order": null
},
"results": [
{
"id": 23,
"name": "qa.lab.example.com",
"fullname": "QA",
"dns_id": 10,
"created_at": "2013-08-13T09:02:31Z",
"updated_at": "2013-08-13T09:02:31Z"
},
{
"id": 25,
"name": "sat.lab.example.com",
"fullname": "SATLAB",
"dns_id": 8,
"created_at": "2013-08-13T08:32:48Z",
"updated_at": "2013-08-14T07:04:03Z"
},
{
"id": 32,
"name": "hr.lab.example.com",
"fullname": "HR",
"dns_id": 8,
"created_at": "2013-08-16T08:32:48Z",
"updated_at": "2013-08-16T07:04:03Z"
}
]
}
The response metadata fields are described below:
total
- total number of objects without any search parameterssubtotal
- number of objects returned with given search parameters (if there is no search, then subtotal
equals total
)page
(Foreman only) - page numberper_page
(Foreman only) - maximum number of objects returned per pagelimit
- (Katello only) specified number of objects to return in collection responseoffset
- (Katello only) number of objects skipped before beginning to return collection.search
- search string (based on scoped_scoped syntax)sort
by
- the field that the collection is sorted byorder
- sort order, either ASC for ascending or DESC for descendingresults
- collection of objects. See Section 5.1.4 for how to change the root name from ‘results’ to something else.Single object JSON responses are used to show a single object. The object’s unique identifier :id
or :name
is required in the GET request. Note that :name
may not always be used as a unique identifier, but :id
can always be used. The format for a single object JSON response consists of only the object’s attributes. There is no root node and no metadata by default. See Section 5.1.4 for how to add a root name.
Below is an example of the format for a single object JSON response: GET /api/domains/23
or GET /api/domains/qa.lab.example.com
{
"id": 23,
"name": "qa.lab.example.com",
"fullname": "QA",
"dns_id": 10,
"created_at": "2013-08-13T09:02:31Z",
"updated_at": "2013-08-13T09:02:31Z"
}
The default root node name for collections is results
but can be changed.
To change the root node name per API request, pass root_name=
as a URL parameter. See example below:
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" \
https://foreman.example.com/api/domains?root_name=data
There is no root node as the default for single object JSON responses, but it can be added.
To change the object’s root node name per API request, pass object_name=
as a URL parameter. See example below:
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" \
https://foreman.example.com/api/domains/23?object_name=record
Currently, there is no option to change or customize which attributes are returned for collections or single objects. In the future, customized partial responses such as fields=field1,field2,field3
or fields=all
may be implemented (#3019). Similarly, there is currently no option to specify child nodes in an API call or to remove child nodes if they are returned by default.
Foreman paginates all collections in the JSON response. The number of objects returned per request is defined in Administer > Settings > General > entries_per_page. The default is 20. Thus, if there are 27 objects in a collection, only 20 will be returned for the default page=1.
To view the next page, pass page=
as a URL parameter. See example below:
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" \
https://foreman.example.com/api/domains?page=2
The example above will show the remaining 7 objects in our example of 27 objects in the collection.
To increase or decrease the number of objects per response, pass per_page=
as a URL parameter. See example below:
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" \
https://foreman.example.com/api/domains?per_page=1000
This will return all the objects in one request since 27 is less than the per_page
parameter set to 1000.
Foreman uses the scoped_search library for searching and filtering which allows all query search parameters to be specified in one string. The syntax is described in the Searching section, and matches exactly the syntax used for the web UI search boxes. This allows you use of the auto-completer and to test a query in the UI before reusing it in the API.
To filter results of a collection, pass search=
as a URL parameter, ensuring that it is fully URL-escaped to prevent search operators being misinterpreted as URL separators. See example below:
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" \
https://foreman.example.com/api/domains?search=name%3Dexample.com
The number of objects returned will be shown in the subtotal
metadata field, and the query string will be shown in the search
metadata field.
Custom sort order per collection can be specified by passing order=
as a URL parameter. See example below:
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" \
https://foreman.example.com/api/domains?order=name+DESC
The default sort order is ascending (ASC) if only a field name is passed. The sort parameters will be shown in sort
by
and order
metadata fields.
The goal is to implement nested routes for all objects as an alternative to filtering collections.
For example, rather then filtering subnets by a specified domain using a search string
$ GET /api/subnets?search=name%3Dqa.lab.example.com
the alternative nested route below returns the same result as the above.
$ GET /api/domains/qa.lab.example.com/subnets
All actions will be accessible in the nested route as in the main route.
The default API version is v2 for Foreman 3.10, however explicitly requesting the version is recommended. Both API v1 and v2 are currently shipped.
There are two methods of selecting an API version:
In the header, pass Accept: application/json,version=2
In the URL, pass /v2/ such as GET /api/v2/hosts
Similarly, v1 can still be used by passing Accept: application/json,version=1
in the header or api/v1/
in the URL.
Updating and creating associations are done in a few different ways in the API depending on the type of association.
To update a one-to-one or a one-to-many association, simply set the name or id on the object. For example, to set a host group for a host, simply set the hostgroup_name or hostgroup_id of the host.
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" \
-H "Content-Type: application/json" -X POST \
-d '{ "hostgroup_name": "telerin" }' \
https://foreman.example.com/api/hosts/celeborn.firstage
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" \
-H "Content-Type: application/json" -X POST \
-d '{ "hostgroup_id": 42 }' \
https://foreman.example.com/api/hosts/celeborn.firstage
To update an association for an object that contains a collection of other objects, there are a few options. First you can set the names or ids:
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" \
-H "Content-Type: application/json" -X POST \
-d '{ "host_names": ["enel.first", "celeborni.first", "elwe.first"] }' \
https://foreman.example.com/api/hostgroups/telerin
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" \
-H "Content-Type: application/json" -X POST \
-d '{ "host_ids": [4, 5, 6] }' \
https://foreman.example.com/api/hostgroups/telerin
This will set the host group’s hosts to enel, celeborn, and elwe (or 4, 5, 6) and only those.
Alternatively, you can pass in a set of objects:
$ curl -k -u admin:changeme -H "Accept: version=2,application/json" \
-H "Content-Type: application/json" -X POST \
-d '{ "domains": [{ "name": "earendil", "id": 1}, { "name": "turgon", "id": 3 }] }' \
https://foreman.example.com/api/subnets/iluvatar
This would set the domains for the subnet to be earendil and turgon. If another domain for example belonged to the subnet before the request, it would be removed.
The API requires authentication for all endpoints, typically using HTTP Basic authentication. Requests with credentials are authenticated against the users stored in Foreman.
HTTP Basic authentication (RFC 2617) is supported by a wide range of API and web clients and works by specifying a Base64-encoded username and password in an Authorization
header. For example, these common clients can access the API with the following arguments:
curl -u admin:changeme
, or curl -u admin
(interactive prompt)wget --user=admin --password=changeme
Every call to the API will require authentication, unless the client supports sessions (see below). Some clients may also support storing credentials in ~/.netrc
or similar for more privacy.
No confidentiality is provided with this method, so it is very important to use HTTPS when connecting to Foreman to prevent the plain-text credentials from being obtained. (Note that when require_ssl
is enabled, access to the API will only be allowed over HTTPS.)
When authenticating to the API, a new server-side session will be created on each request and the response will contain a cookie containing a session ID. If this cookie is stored by the client, it can be used on subsequent requests so the credentials are only passed over the connection once.
A basic authenticated request to the status API returns the following Set-Cookie
header, containing a _session_id
cookie:
> GET /api/v2/status HTTP/1.1
> Authorization: Basic YWRtaW46Y2hhbmdlbWU=
> Host: foreman.example.com
> Accept: */*
< HTTP/1.1 200 OK
< ...
< Set-Cookie: _session_id=572ca37e8c5845b900cc58d45d6e1e34; path=/; secure; HttpOnly
When supplying this on subsequent requests, they will use the same account:
> GET /api/v2/status HTTP/1.1
> Host: foreman.example.com
> Accept: */*
> Cookie: _session_id=572ca37e8c5845b900cc58d45d6e1e34
< HTTP/1.1 200 OK
< ...
Command-line clients may support cookie jars for automatic storage of cookies, e.g. curl -c ~/.foreman_cookies -b ~/.foreman_cookies
will automatically store and use cookies.
Alternatively to basic authentication, limited OAuth 1.0 authentication is supported in the API.
OAuth must be enabled in Foreman settings. In Administer > Settings > Authentication, search for OAuth active configuration and set it to Yes. Then set OAuth consumer key to some string. This will be a token used by all OAuth clients.
If you want all API requests made using OAuth to be authorized as built-in anonymous admin user keep OAuth map users set to No. If you want to specify the user under which the request is made, change this configuration option to Yes. This allows client to send FOREMAN-USER header with the login of existing Foreman user. Please note that this header is not signed in OAuth request so can be forged. Anyone with valid consumer key can impersonate any Foreman user.
Usually some OAuth client library is used to generate the request. An example of curl command can be found here to better understand how it works
$ curl 'https://foreman.example.com/api/architectures' \
-H 'Content-Type: application/json' \
-H 'Accept: application/json,version=2' \
-H 'FOREMAN-USER: ares' \
-H 'Authorization: OAuth oauth_version="1.0",oauth_consumer_key="secretkey",oauth_signature_method="hmac-sha1",oauth_timestamp=1321473112,oauth_signature=Il8hR8/ogj/XVuOqMPB9qNjSy6E='
In example above we list architectures using OAuth for authentication. We try to do the request under user with login ares, if mapping is enabled on Foreman side, the result will only include architectures, that user ares can see. Note that we constructed the signature manually, this should change with any oauth_timestamp change. Also it reflects every parameter, HTTP method and URI change. Therefore we recommend using some OAuth client library that will construct all OAuth parameters.
The following examples show how to do basic API operations using apipie-bindings.
Get of a collection of domains: GET /api/domains
Call the index function of the domains resource.
#!/usr/bin/env ruby
require 'apipie-bindings'
url = 'https://foreman.example.com/'
username = 'admin'
password = 'changeme'
api = ApipieBindings::API.new({:uri => url, :username => username, :password => password, :api_version => '2'})
domains = api.resource(:domains).call(:index)
domains['results'].each do |domain|
puts domain
end
$ ruby domains.rb
{"fullname"=>"", "dns_id"=>1, "created_at"=>"2016-05-06 08:46:20 UTC", "updated_at"=>"2016-11-24 11:49:06 UTC", "id"=>1, "name"=>"example.com"}
Get a single domain: GET /api/domains/:id
or GET /api/domains/:name
Call the show function of the domains resource with the object’s unique identifier :id
or :name
.
#!/usr/bin/env ruby
require 'apipie-bindings'
url = 'https://foreman.example.com/'
username = 'admin'
password = 'changeme'
api = ApipieBindings::API.new({:uri => url, :username => username, :password => password, :api_version => '2'})
puts api.resource(:domains).call(:show, {:id => 1})
puts api.resource(:domains).call(:show, {:id => 'example.com'})
Create a new domain: POST /api/domains
Call the create function of the domains resource with a JSON data hash containing the required fields to create the object. In this example, a domain is being created.
#!/usr/bin/env ruby
require 'apipie-bindings'
url = 'https://foreman.example.com/'
username = 'admin'
password = 'changeme'
api = ApipieBindings::API.new({:uri => url, :username => username, :password => password, :api_version => '2'})
api.resource(:domains).call(:create, {:domain => {:name => "foo.example.com", :fullname => "foo.example.com"}})
Update a domain: PUT /api/domains/:id
or PUT /api/domains/:name
Call the update function of the domains resource with the object’s unique identifier, either :id
or :name
, plus a JSON data hash containing only the data to be updated. In this example, only the domain name is being updated.
#!/usr/bin/env ruby
require 'apipie-bindings'
url = 'https://foreman.example.com/'
username = 'admin'
password = 'changeme'
api = ApipieBindings::API.new({:uri => url, :username => username, :password => password, :api_version => '2'})
api.resource(:domains).call(:update, {:id => 3, :domain => {:name => "foo.example.com", :fullname => "foo.example.com"}})
Delete a domain: DELETE /api/domains/:id
or DELETE /api/domains/:name
Call the destroy function of the domains resource with the object’s unique identifier, either :id
or :name
.
#!/usr/bin/env ruby
require 'apipie-bindings'
url = 'https://foreman.example.com/'
username = 'admin'
password = 'changeme'
api = ApipieBindings::API.new({:uri => url, :username => username, :password => password, :api_version => '2'})
api.resource(:domains).call(:destroy, {:id => 3})
The following examples show how to do basic API operations using GraphQL.
The GraphqlAPI is available at /api/graphql
.
This command shows how you can query the API with curl.
curl -u username:password -X POST -H "Content-Type: application/json" --data '{ "query": "{ domains { nodes { name } } }" }' https://foreman.example.com/api/graphql
Get of a collection of domains:
Query:
{
domains(search: "name ~ example.com") {
nodes {
name
}
}
}
Result:
{
"data": {
"domains": {
"nodes": [
{
"name": "example.com"
}
]
}
}
}
Get a single domain:
Query:
{
domain(id: "MDE6RG9tYWluLTQ=") {
name,
createdAt
}
}
Result:
{
"data": {
"domain": {
"name": "example.com",
"createdAt": "2017-01-18T11:12:52+01:00"
}
}
}
Starting with Foreman 2.0 Foreman uses Dynflow backed by Sidekiq by default on all supported platforms. This change is described in greater detail in Upcoming changes to Dynflow. The original Dynflow executor service (called dynflowd
) was replaced by redis
and a set of dynflow-sidekiq@*
services. This new deployment model should address issues we have seen when restarting the Dynflow executor. It also allows us scale more easily, dedicate workers to specific queues and increase the overall throughput. The following examples show how to scale Dynflow up in the new model.
Out of the box, foreman ships with orchestrator and a single worker If you have Katello, you will get an additional worker for processing of the host queue
# ls -l /etc/foreman/dynflow/
total 1
-rw-r--r--. 1 root foreman 51 May 14 07:35 orchestrator.yml
-rw-r--r--. 1 root foreman 59 May 14 07:35 worker.yml
The orchestrator consumes items only from the dynflow_orchestrator
queue and has only one thread. This is by design. Do not change this
# cat /etc/foreman/dynflow/orchestrator.yml
:concurrency: 1
:queues:
- dynflow_orchestrator
The regular worker has 5 threads and consumes items from default and remote_execution queues. It is not recommended to change the configuration for this process either, because the changes would be overwritten by the installer, if run again.
# cat /etc/foreman/dynflow/worker.yml
:concurrency: 5
:queues:
- default
- remote_execution
Scaling up is pretty straightforward, especially if you want to only scale up what you have
Here we use symbolic links to “share” the actual configuration among worker
, worker-1
and worker-2
# cd /etc/foreman/dynflow
# ln -s worker.yml worker-1.yml
# ln -s worker.yml worker-2.yml
Check that the symbolic links are pointing to the right files
# ls -l /etc/foreman/dynflow/
total 2
-rw-r--r--. 1 root foreman 51 May 14 07:35 orchestrator.yml
lrwxrwxrwx. 1 root root 10 May 14 11:24 worker-1.yml -> worker.yml
lrwxrwxrwx. 1 root root 10 May 14 11:24 worker-2.yml -> worker.yml
-rw-r--r--. 1 root foreman 59 May 14 07:35 worker.yml

Scaling down is just reverse process, let’s say having worker
, worker-1
and worker-2
was
an overkill and we think we would be fine with just worker
and worker-1
.
# systemctl disable --now dynflow-sidekiq@worker-2
Removed /etc/systemd/system/multi-user.target.wants/dynflow-sidekiq@worker-2.service.
# rm /etc/foreman/dynflow/worker-2.yml
For this we need to create a new configuration for a worker (or just copy an existing one and change the relevant lines)
Create the configuration file, here we create a worker called rex
having 5 threads and consuming items from the remote_execution

Foreman supports creating and managing hosts on a number of virtualization and cloud services - referred to as “compute resources” - as well as bare metal hosts.
The capabilities vary between implementations, depending on how the compute resource provider deploys new hosts and what features are available to manage currently running hosts. Some providers are able to support unattended installation using PXE, while others are image-based. Some providers have graphical consoles that Foreman interfaces to, and most have power management features. A summary of all providers and their support features is given below, and more detailed sections follow with specific notes.
Provider | Package | Unattended installation | Image-based | Console | Power management | Networking |
---|---|---|---|---|---|---|
EC2 | foreman-ec2 | no | yes | read-only | yes | IPv4 |
Google Compute Engine | foreman-plugin-google | no | yes | read-only | yes | IPv4 |
Libvirt | foreman-libvirt | yes | yes | VNC or SPICE | yes | MAC |
OpenStack Nova | foreman-openstack | no | yes | no | yes | IPv4 |
oVirt / RHEV | foreman-ovirt | yes | yes | VNC or SPICE | yes | MAC |
VMware | foreman-vmware | yes | yes | VNC | yes | MAC |
Support for these features is aimed at being as transparent as possible, allowing the same configuration to be applied to hosts irrespective of the provider in use (compute resource or not). The selection of compute resource is made when creating a new host and the host in Foreman’s database remains associated to the VM that’s created, allowing it to be managed throughout the lifetime of the host.
Networking varies between providers - where “MAC” is specified, the compute resource provides the MAC address for newly created virtual machines (layer 2 networking), and IP addresses are assigned in/by Foreman. Where “IPv4” and/or “IPv6” is specified, the compute resource assigns an IP address for virtual machine interfaces (layer 3 networking) and the addresses will be stored by Foreman when creating a host.
The following steps describe how to configure a compute resource and provision new hosts on it.
Ensure the necessary package for the provider (from the above table) is installed, e.g. yum -y install foreman-ovirt
. Restart the Foreman application to complete installation.
Add a compute resource under Infrastructure > Compute Resources > New Compute Resource. Select the provider type from the menu and appropriate configuration options will be displayed. Check the notes sections below for any provider-specific setup instructions.
Click the Test Connection button after entering the configuration. If no error is displayed, the test was successful.
After saving the compute resource, existing virtual machines can be browsed by clicking on the compute resource and the Virtual Machines tab.
For providers that use images, click on the compute resource, then the Images tab, where known images are listed. To register images that Foreman can use, click New Image and enter the details.
To provision a new host on this compute resource, from Hosts, click New Host and select the compute resource from the Deploy to menu.
Also note the following features:
When viewing a host, power management controls and the console access button are in the top right hand corner of the page.
If a host provisioned on a compute resource is deleted, the VM and associated storage on the compute resource will also be deleted.
Users in Foreman can have access restricted to hosts present on certain compute resources. For more information, see Filtering in 4.1.2 Roles and Permissions.
A compute profile is a way of expressing a set of defaults for VMs created on a specific compute resource that can be mapped to an operator-defined label. This means an administrator can express, for example, what “Small”, Medium” or “Large” means on all of the individual compute resources present for a given installation.
In combination with host groups, this allows a user to completely define a new host from just the Host tab of the New Host form.
You can find the configuration for compute profiles at Infrastructure > Compute Profiles
By default, Foreman comes with 3 predefined profiles; “1-Small”, “2-Medium”, and “3-Large” (the numbers are just to make them sort nicely). They come with no associated configuration for any particular compute resource, and as such, they can be deleted or renamed as required.
This walkthrough will define what “1-Small” means for a particular installation. It will also assume there are two compute resources; one Libvirt and one EC2 (these make a good example as they are very different).
Start by editing the compute profile, by clicking its name in the profile list. This leads to a list of all your current compute resources. Later, once the configuration is done, this list will also display the current defaults configured for each compute resource.
Clicking on the EC2 resource will bring up a page very similar to the one used when provisioning a single host. Here an administrator can set what “1-Small” means on this specific EC2 resource. For this example, “m1.small” is selected as the size. Defaults can also be specified for the image choice, the security groups, and so on.
The changes are submitted, and on returning to the profile list, the new EC2 defaults will be shown.
In a very similar manner, the Libvirt resource can be clicked upon, and some defaults assigned. For this example, since this is the “1-Small” profile, 1 CPU, 512MB of RAM, a single bridged network device, and a 5GB disk are selected.
Again, the changes are submitted.
Now visit Hosts > New Host. At first, things look exactly as before, but once a compute resource is selected which has at least one compute profile, a new combo-box will appear. This permits the user to select a profile to apply to this host. For this example, the Libvirt resource is selected, followed by the “1-Small” profile.
Once the profile is selected, the Virtual Machine tab will automatically update to use the defaults configured in the “1-Small” profile.
Assuming the defaults are suitable, the host has now been defined solely by selecting a host group and a profile. It’s also possible to associate a profile with a host group in the host group edit page, which will automatically select that profile when the host group is selected.
A finish-based example for configuring EC2 provisioning is given on the Foreman blog: EC2 provisioning using Foreman.
restorecon -vv /usr/share/foreman/gce.json
All Google Compute Engine access is contained within a “project” set up via the Google Developers Console. Access the Google Developers Console, and click Create Project.
By default, your project will have the Compute Engine and App Engine services enabled. Now go to the Compute Engine API Overiew, and select the Google Compute Engine API.
Under APIs & Services > Library, apply filter compute and select API then click the Enable button.
Next under Credentials, click Create Credentials > Create service account key and choose your service account for Compute Engine.
Click Generate new JSON key and save the new .json file. This should be uploaded to the Foreman server to a location that the ‘foreman’ user can read, such as /usr/share/foreman/gce.json
. You don’t need to provide any password to Foreman to use this JSON key.
In Foreman, under Infrastructure > Compute resources > New compute resource, select Google from the provider dropdown menu and fill in the GCE-specific fields as follows:
To connect to the hypervisor using SSH:
qemu+ssh://root@hypervisor.example.com/system
to use the remote ‘root’ accountqemu+ssh://hypervisor.example.com/system
to use the remote ‘foreman’ accountThe first two steps above can be done with something like:
root# mkdir /usr/share/foreman/.ssh
root# chmod 700 /usr/share/foreman/.ssh
root# chown foreman:foreman /usr/share/foreman/.ssh
When using distribution packages, the directory should already be created for you so you could skip the above. Although following is necessary:
root# su foreman -s /bin/bash
foreman$ ssh-keygen
foreman$ ssh-copy-id root@hostname.com
foreman$ ssh root@hostname.com
exit
When using SELinux make sure the directory and the files have correct labels
of ssh_home_t
:
ls /usr/share/foreman/.ssh -Zd
drwx------. foreman foreman system_u:object_r:ssh_home_t:s0 /usr/share/foreman/.ssh
ls /usr/share/foreman/.ssh -Z
-rw-------. foreman foreman unconfined_u:object_r:ssh_home_t:s0 id_rsa
-rw-r--r--. foreman foreman unconfined_u:object_r:ssh_home_t:s0 id_rsa.pub
-rw-r--r--. foreman foreman unconfined_u:object_r:ssh_home_t:s0 known_hosts
If not, restore the context:
restorecon -RvF /usr/share/foreman/.ssh
To connect to the hypervisor over TCP without authentication or encryption (not recommended):
listen_tls = 0
listen_tcp = 1
auth_tcp = "none"
LIBVIRTD_ARGS="--listen"
in /etc/sysconfig/libvirtdqemu+tcp://hypervisor.example.com:16509/system
If you have difficulty connecting, test access using the virsh command under the ‘foreman’ account on the Foreman host first, e.g. virsh -c qemu+ssh://hypervisor.example.com/system list
.
Image based provisioning can be used by provisioning a VM with a backing image and then running a finish script over SSH, in the same manner as the EC2 provider. The type of provisioning method can be selected under the “Operating system” tab when creating a new host. To configure image/template-based provisioning:
Two methods to complete provisioning are supported. Either by SSHing into the newly created VM and running a script:
Or select the userdata checkbox when adding the image to Foreman, and a cloud-init compatible disk will be attached to the VM containing the userdata:

My templates/RHEL 6
or RHEL 6
if it isn’t in a folder. Do not include the datacenter name.The same process can also be done using a user_data template. To configure image/template-based provisioning without SSH, make the following adjustments for the former procedure:
Consoles are provided using VNC connections from Foreman to the ESX server, which requires a firewall change to open the respective ports (TCP 5901 to 5964)
Add the following file content:
Apply and check the firewall rule:
Lastly, make the rule persistent.
With ESX:
With ESXi:
If permanent shared storage is available (direct-attach SAN, etc): rather than doing a file copy on each server, use a symlink instead. Once it’s changed on the shared storage, run a loop to refresh the firewall services. The local.sh file still needs to be created.
Example:
The minimum permissions to properly provision new virtual machines are:
Compute resource passwords and secrets are stored on the Foreman database using a secret - the encryption key - and ciphered using AES-256-CBC.
The encryption key can usually be found in /etc/foreman/encryption_key.rb
, which is symlinked to /usr/share/foreman/config/initializers/encryption_key.rb
. The value of the ENCRYPTION_KEY variable must be at least 32 bytes long.
If you want to regenerate the key, you can run foreman-rake security:generate_encryption_key
. Please remember that previously encrypted passwords cannot be decrypted with a different encryption key, so decrypt all passwords before changing your encryption key.
After you make sure you have a valid encryption key, you can encrypt your Compute Resource secrets in the database by running foreman-rake db:compute_resources:encrypt
.
To unencrypt them, run the task foreman-rake db:compute_resources:decrypt
.
Keep in mind passwords are encrypted in the Foreman database, but Foreman will decrypt them and use unencrypted credentials to authenticate to Compute Resources.

The Foreman web application needs to communicate securely with associated smart proxies and Puppet servers, plus users and applications connecting to the web interface. This section details recommended SSL configurations.
In a typical ENC-based setup with reporting, Puppet servers require access to Foreman for three tasks:
All traffic here is initiated by the Puppet server itself. Other traffic from Foreman to the Puppet server for certificate signing etc. is handled via smart proxies (SSL configuration covered in the next section).
The Foreman interface authorizes access to Puppet server interfaces based on its list of registered smart proxies with the Puppet feature, and identifies hosts using client SSL certificates.
Five main settings control the authentication, the first are in Foreman under Settings, Authentication:
And two in config/settings.yaml
:
Using Apache HTTP with mod_ssl is recommended. For simple setups, the Puppet certificate authority (CA) can be used, with Foreman and other hosts using certificates generated by puppet cert
.
/etc/puppetlabs/puppet/foreman.yaml
or /etc/puppet/foreman.yaml
) should have these settings:Warning messages will be printed to Foreman’s log file (typically /var/log/foreman/production.log
) when SSL-based authentication fails.
A typical small setup will use a single Puppet CA and certificates it provides for the Foreman host and Puppet server hosts. In larger setups with multiple CAs or an internal CA, this will require more careful configuration to ensure all hosts can trust each other.
In non-SSL setups, host-based authentication can be performed, so any connection from a host running a puppet smart proxy is able to access the interfaces.
Entirely disabling authentication isn’t recommended, since it can lead to security exploits through YAML import interfaces and expose sensitive host information, however it may be useful for troubleshooting.
Foreman makes HTTP requests to smart proxies for a variety of orchestration tasks. In a production setup, these should use SSL certificates so the smart proxy can verify the identity of the Foreman host.
In a simple setup, a single Puppet Certificate Authority (CA) can be used for authentication between Foreman and proxies. In more advanced setups with multiple CAs or an internal CA, the services can be configured as follows.
/etc/foreman-proxy/settings.yml
contains the locations to the SSL certificates and keys:
---
# SSL Setup
# if enabled, all communication would be verified via SSL
# NOTE that both certificates need to be signed by the same CA in order for this to work
# see https://theforeman.org/manuals/3.10/index.html#4.3.10SSL for more information
:ssl_certificate: /etc/puppetlabs/puppet/ssl/certs/FQDN.pem
:ssl_ca_file: /etc/puppetlabs/puppet/ssl/certs/ca.pem
:ssl_private_key: /etc/puppetlabs/puppet/ssl/private_keys/FQDN.pem
In this example, the proxy is sharing Puppet’s certificates, but it could equally use its own.
In addition it contains a list of hosts that connections will be accepted from, which should be the host(s) running Foreman:
# the hosts which the proxy accepts connections from
# commenting the following lines would mean every verified SSL connection allowed
:trusted_hosts:
- foreman.corp.com
#- foreman.dev.domain
For Foreman to connect to an SSL-enabled smart proxy, it needs configuring with SSL certificates in the same way.
The locations of the certificates are managed in the Settings page, under Provisioning - the ssl_ca_file, ssl_certificate and ssl_priv_key settings. By default these will point to the Puppet locations - for manually generated certificates, or non-standard locations, they may have to be changed.
Lastly, when adding the smart proxy in Foreman, ensure the URL begins with https://
rather than http://
.
If using Puppet’s certificates, the following lines will be required in puppet.conf to relax permissions to the puppet
group. The foreman
and/or foreman-proxy
users should then be added to the puppet
group.
[main]
privatekeydir = $ssldir/private_keys { group = service }
hostprivkey = $privatekeydir/$certname.pem { mode = 640 }
Note that the “service” keyword will be interpreted by Puppet as the “puppet” service group.
This chapter will provide you with information how to backup and recover your instance. All commands presented here are just examples and should be considered as a template command for your own backup script which differs from one environment to other.
It is possible to perform a migration by doing backup one one host and recovery on a different host, but in this case pay attention to different configuration between the two hosts.
This can be applied to the Foreman application itself, but pay attention when migrating smart-proxy and services because things like different IP addresses or hostnames will need manual intervention.
This chapter will provide you with information how to backup a Foreman instance.
Run foreman-rake db:dump
. It will print a message when it finishes with the dump file location relative to the Foreman root.
On Red Hat compatible systems issue the following command to backup whole /etc directory structure:
tar --selinux -czvf etc_foreman_dir.tar.gz /etc/foreman
For all other distribution do similar command:
tar -czvf etc_foreman_dir.tar.gz /etc/foreman
On the Puppet server node, issue the following command to backup Puppet certificates on Red Hat compatible systems
tar --selinux -czvf var_lib_puppet_dir.tar.gz /etc/puppetlabs/puppet/ssl
For all other distribution do similar command:
tar -czvf var_lib_puppet_dir.tar.gz /etc/puppetlabs/puppet/ssl
Under a Puppet non-AIO installation, back up /var/lib/puppet/ssl
instead.
Depending on used software packages, perform backup of important data and configuration files according to the documentation. For ISC DHCP and DNS software, these are located within /etc and /var directories depending on your distribution as well as TFTP service.
Recovery process is supposed to be performed on the same host the backup was created on on the same distribution and version.
If you planning to migrate Foreman instance, please read remarks in the beginning of this chapter.
Note: Foreman instance must be stopped before proceeding.
Run foreman-rake db:import_dump file=/your/db/dump/location
. This will load your
dump into the current database for your environment. It will print a message
to notify you when it has finished importing the dump.
Remember to stop the Foreman instance and any other process consuming data from the database temporarily during the import and turn it back on after it ends.
On Red Hat compatible systems issue the following command to restore whole /etc directory structure:
tar --selinux -xzvf etc_foreman_dir.tar.gz -C /
For all other distribution do similar command:
tar -xzvf etc_foreman_dir.tar.gz -C /
It is recommended to extract files to an empty directory first and inspect the content before overwriting current files (change -C option to an empty directory).
On the Puppet server node, issue the following command to restore Puppet certificates on Red Hat compatible systems
tar --selinux -xzvf var_lib_puppet_dir.tar.gz -C /
For all other distribution do similar command:
tar -xzvf var_lib_puppet_dir.tar.gz -C /
It is recommended to inspect the content of the restore first (see above).
Depending on used software packages, perform recovery of important data and configuration files according to the documentation. This depends on the software and distribution that is in use.
It’s preferable when migrating to keep the FQDN unchanged to reduce the risk of configuration errors from references to the old hostname.
However if the FQDN does change, check and update the following items:
puppet cert generate NEW_FQDN
conf.d/*-{foreman,puppet}.conf
with new SSL cert/key filenames, ServerName and VirtualHost IP addresses if applicable/etc/foreman-proxy

The following tutorial explains how to set up Foreman authentication against FreeIPA (or Identity Management) server. First part of the tutorial describes how to configure Foreman machine via Foreman installer options. The second one shows how to achieve the same result without using these options.
We assume the Foreman machine is FreeIPA-enrolled:
On the FreeIPA server, we create the service. (Please make sure you have obtained Kerberos ticket before this step - for example, by using kinit.)
Then we install Foreman.
This option can be used for the reconfiguration of existing installation as well.
In case you want to use IPA server’s host-based access control (HBAC) features (make sure allow_all rule is disabled), the default PAM service name (which would be matched by HBAC service name) is foreman. You can override the default name with:
For more information about HBAC configuration see section below.
We suppose that the Foreman machine is FreeIPA-enrolled and HTTP/<the-foreman-fqdn>
service has been created on FreeIPA server.
At first we create HBAC (host-based access control) service and rule on the FreeIPA server. In the following examples, we will use the PAM service name foreman-prod.
On the FreeIPA server, we define the HBAC service and rule and link them together:
Then we add user we wish to have access to the service foreman-prod, and the hostname of our Foreman server:
Alternatively, host groups and user groups could be added to the allow_foreman_prod rule.
At any point of the configuration, we can check the status of the rule:
Chances are there will be HBAC rule allow_all matching besides our new allow_foreman_prod rule. See http://www.freeipa.org/page/Howto/HBAC_and_allow_all for steps to disable the catchall allow_all HBAC rule while maintaining the correct operation of your FreeIPA server and enrolled clients. The goal is only allow_foreman_prod matching when checked with ipa hbactest
.
In this part of the tutorial we will show how to set up Foreman authentication manually (without using installer option).
At first we enroll Foreman machine and define HTTP/<the-foreman-fqdn>
service in the FreeIPA server. Then we define HBAC service and rules (for more information see the previous section). In the following steps we will use the HBAC service name foreman-prod.
Next step is to define matching PAM service on the Foreman machine. We create file /etc/pam.d/foreman-prod
with the following content:
We will also want to enable two SELinux booleans on the Foreman machine:
Get the keytab for the service and set correct permissions (we assume the FreeIPA server is ipa.example.com, adjust to match your setup):
Install mod_auth_gssapi and mod_authnz_pam:
Configure the module to be used by Apache (we assume the realm is EXAMPLE.COM, adjust to match your setup):
We tell Foreman that it is OK to trust the authentication done by Apache by adding to /etc/foreman/settings.yaml
or under Administer > Settings > Authentication:
We restart Apache:
The machine on which you run the browser to access Foreman’s WebUI needs to be either FreeIPA-enrolled to the FreeIPA server or at least configured (typically in /etc/krb5.conf
) to know about the FreeIPA server Kerberos services. The browser needs to have the Negotiate Authentication enabled; for example in Firefox, in the about:config
settings, network.negotiate-auth.trusted-uris needs to include the Foreman server FQDN or its domain. If you then kinit
as existing Foreman user to obtain Kerberos ticket-granting ticket, accessing Foreman’s WebUI should not ask for login/password and should display the authenticated dashboard directly.
Please note that we use directive require pam-account foreman-prod
to also check the access against FreeIPA’s HBAC rule. If you do not see Kerberos authentication passing, check that the user is allowed access in FreeIPA (in the section about HBAC configuration we’ve named the HBAC rule allow_forman_prod).
The FreeIPA server can be used as an authentication provider for Foreman’s standard logon form. We assume the Foreman machine is already FreeIPA-enrolled so sssd is configured to be able to facilitate the authentication, and we have PAM service foreman-prod configured.
We will install the necessary Apache modules:
We will then configure Apache to perform PAM authentication (and access control check) using the PAM service foreman-prod, for example in configuration file /etc/httpd/conf.d/intercept_form_submit.conf
:
After restarting Apache with service httpd restart
, you should be able to log in to Foreman’s WebUI as existing user, using password from the FreeIPA server. Please note that intercept_form_submit_module uses authnz_pam_module to run not just the authentication, but access check as well. If the authentication does not pass and you are sure you use the correct password, check also that the user is allowed access in FreeIPA HBAC rules.
So far we have tried external authentication for existing Foreman users.
However, it is also possible to have the user’s records in Foreman created automatically, on the fly when they first log in using external authentication (single sign-on, PAM).
The first step to enable this feature is to add
:authorize_login_delegation_auth_source_user_autocreate: External
to /etc/foreman/settings.yaml
or under Administer > Settings > Authentication.
Since we will want the newly created user records to have valid name and email address, we need to set up sssd to provide these attributes and mod_lookup_identity to pass them to Foreman. We start by installing the packages:
Amend the configuration of sssd in /etc/sssd/sssd.conf
:
Configure Apache to retrieve these attributes, for example in /etc/httpd/conf.d/lookup_identity.conf
:
Restart both sssd and Apache:
Now when you log in either using Kerberos ticket or using user’s FreeIPA password (make sure the user has access allowed in FreeIPA HBAC rule), even if the user did not log in to Foreman before, their record will be populated with name and email address from the FreeIPA server (you can check in the top right corner that the full name is there) and they will also be updated upon every subsequent externally-authentication logon.
You might notice that the newly created user does not have many access right. To fully use the central identity provider like FreeIPA, it can be useful to link group membership of externally-authenticated Foreman users to the group membership of users in FreeIPA, and then set Foreman roles to these user groups. That way when a new network administrator has their record created in FreeIPA with proper user groups and then logs in to Foreman for the first time, their Foreman account will automatically get group memberships in Foreman groups, giving them appropriate roles and access rights.
The prerequisite is obviously to have the user groups and memberships set appropriately for your organization in FreeIPA.
For each FreeIPA user group that should have some semantics in Foreman, we create new user groups in Foreman, and then use the tab External groups and Add external user group to add name of the user group in FreeIPA, for Auth source EXTERNAL. We can then assign roles to this Foreman user group to match the desired role for users from the given FreeIPA user group.
Upon their first login, externally-authenticated users will get their group membership in Foreman set to match the mapping to FreeIPA groups and their group membership in FreeIPA. Upon subsequent externally-authenticated logons, the membership in these mapped groups will be updated to match the current membership in FreeIPA.
If clear namespace separation of internally and externally authenticated users is desired, we can distinguish the externally authenticated (and populated) users by having @REALM part in their user names.
For the Kerberos authentication, using KrbLocalUserMapping Off
will keep the REALM part of the logon name:
For the PAM authentication, using InterceptFormLoginRealms EXAMPLE.COM
will make the user’s login include this @REALM part (even if the
user did not explicitly specify it), thus matching the username seen by Foreman when authenticated via Kerberos ticket:
With this configuration, the @REALM will be part of the username and it would be clear that bob is INTERNAL-authenticated and bob@EXAMPLE.COM is different user, EXTERNAL-authenticated. The admin then can manually create another admin@EXAMPLE.COM user (with administrator privileges) and even the admin can use Kerberos or PAM authentication in this setup.
An OpenID Provider(OP) implements a Single Sign-on (SSO) using an OpenID Connect (OIDC) protocol. OIDC verifies the identity of the End-user depending on the given authentication details. In this example, Keycloak is used as the OpenID provider, and Foreman is the Relying Party (RP).
OpenID provider provides an ID Token, encoded in JSON Web Token (JWT) to Foreman.
An example of an encoded JWT ID Token:
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c
As a system administrator, execute the following procedure to configure Foreman.
Prerequisites
Procedure
# yum install mod_auth_openidc keycloak-httpd-client-install -y
Note: OIDC support is added to the keycloak-httpd-client-install package with minimum requirement of version 1.x.
# export KEYCLOAK_URL=https://keycloak.example.com
# export KEYCLOAK_REALM=ssl-realm
# export KEYCLOAK_USER=admin
# keycloak-httpd-client-install --app-name foreman-openidc --keycloak-server-url $KEYCLOAK_URL --keycloak-admin-username $KEYCLOAK_USER --keycloak-realm $KEYCLOAK_REALM --keycloak-admin-realm master --keycloak-auth-role root-admin -t openidc -l /users/extlogin -d
Warning: This feature is not yet supported by foreman-installer. As a result, re-running the foreman-installer command can purge the changes in Apache files added by the keycloak-httpd-client-install.
Log in to the Foreman admin page and click Administer → Settings → Authentication.
Set authorize_login_delegation_auth_source_user_autocreate to External to enable auto-creation of users from external OpenID provider.
OIDC Algorithm: Algorithm type with which JWT was encoded in the OpenID provider. For example, set this parameter to RS256.
OIDC Audience: Name of the OIDC audience used for authentication. In case of Keycloak, it is Client ID.
OIDC Issuer: The Issuer (iss) claim identifies the principal that issues the JWT.
OIDC JWKS URL: Open JSON Web key Set URL to validate the signature.
An end user can perform SSO by the following ways:
To perform the mentioned ways, ensure that Foreman is configured.
Procedure
Foreman will automatically redirect to Keycloak Sign-in page. If credentials are correct, it redirects to the Foreman dashboard.
Hammer-cli supports the following methods to obtain ID token and perform authentication:
Authorization Code Flow is a two step process:
Procedure
Get the token endpoint and authorization endpoint from the .well-known/openid-configuration URL of your OpenID provider. For example in case of Keycloak, get token and authorization endpoint from: https://
Log in to Foreman:
hammer auth login oauth --two-factor --oidc-token-endpoint https://keycloak.example.com/token --oidc-authorization-endpoint https://keycloak.example.com/auth --oidc-client-id foreman-client --oidc-redirect-uri urn:ietf:wg:oauth:2.0:oob
The end user provides username and password for authentication and makes a POST request to the OpenID provider to exchange the password for an access token.
Procedure
Get token endpoint from the .well-known/openid-configuration URL of your OpenID provider. For example in case of Keycloak get token endpoint from: https://
Log in to Foreman:
hammer auth login oauth --oidc-token-endpoint https://keycloak.example.com/token --oidc-client-id foreman-client --username myuser --password changeme
The following steps are suggested when configuring multiple Foreman instances to work together. They will ensure that data, passwords, and cookies are shared between multiple instances.
$app_root
is wherever you installed Foreman, usually /usr/share/foreman
.
All Foreman instances in a cluster/group must point to the same database. This can be done during the initial installation (through flags or altering foreman_installer_answers.yaml
) or by directly altering /etc/foreman/database.yaml
and pointing the correct environment (usually production) to your Foreman DB, then restarting Foreman.
As described in 5.2.10, passwords stored locally in Foreman’s DB are encrypted. In order for multiple Foreman instances to encrypt and decrypt passwords correctly, they all need to have the same encryption key defined in /etc/foreman/encryption_key.rb
.
The last file required to make a Foreman cluster work is $app_root/config/initializers/local_secret_token.rb
, which is used to sign cookies. This should be set the same across all Foreman servers in your cluster. Once you have set local_secret_token.rb
, restart Foreman and clear Foreman’s cache:
Note: Without this change, the user may need to log in multiple times or run in to “Invalid Authenticity Token”/CSRF issues.
There are other considerations when creating a cluster:
There are two proxy settings in Foreman to allow HTTP(s) communication through firewalls.
Global option
In Administer - Settings - General menu there are two options available for setting outgoing HTTP(s) proxy for all communication (e.g. to Smart Proxies, Compute Resources):
http://[user:password@]HOST:PORT
Both settings can also be configured via settings.yaml
file via
:http_proxy:
and :http_proxy_except_list:
options.
Infrastructure - HTTP Proxies page
It is possible to configure multiple HTTP(s) proxies for various Compute Resources. Each individual Compute Resources can be associated with a different proxy. To create proxy URL, visit Infrastructure - HTTP Proxies and then associate the proxy with a Compute Resource.
Currently HTTP Proxies are supported by the following Compute Resources:
Notes
Both cases only affect outgoing HTTP(s) connection of the Foreman core application (Ruby on Rails process). There are other plugins and components running on a typical Foreman deployment (e.g. websocket proxy, Pulp, Candlepin) and those services are not affected. Most of them can be configured separately.
Please refer to the plugins manual.
Foreman uses the excellent javascript VNC library noVNC, which allows clientless VNC within a web browser. When a console is opened by the user’s web browser, Foreman opens a connection to TCP Port 5910 (and up) on the hypervisor and redirects that itself.
For VNC only, encrypted connections are the default on new installations. If you have an older installation of Foreman, you can configure encrypted websockets by adding these lines to /etc/foreman/settings.yml
, and configuring the correct path to the same SSL certificates apache uses:
:websockets_encrypt: on
:websockets_ssl_key: /var/lib/puppet/ssl/private_keys/foreman.example.com
:websockets_ssl_cert: /var/lib/puppet/ssl/certs/foreman.example.com
about:config
and enable network.websocket.allowInsecureFromHTTPS
.chrome://flags/
and enable allow-insecure-websocket-from-https-origin. Recent versions of Chrome (e.g. 44) have removed the flag. An alternative workaround is to launch Chrome with a command-line argument like this $ google-chrome-stable --allow-running-insecure-content &
# openssl x509 -in /etc/ssl/certs/foreman.domain.tld.crt -text -noout |grep Algorithm Signature Algorithm: *sha1WithRSAEncryption*
Edit /etc/foreman/settings.yaml
and either uncomment or add these lines:
:logging:
:level: debug
And reload Foreman:
systemctl restart foreman
More types of log messages can be enabled from settings.yaml. The following loggers are enabled by default:
The following loggers needs to be explicitly enabled:
Uncomment or add a :loggers block to enable or disable loggers:
:loggers:
:ldap:
:enabled: true
Plugins may add their own logs too, see /etc/foreman/plugins/ for their possible configuration.
Also see Configuration Options for more information.
Starting from Foreman 1.18, logging stack can be configured to log into system journal:
:logging:
:level: info
:type: journald
On Red Hat compatible systems, journald is running in transient mode by default and forwards all logs to syslog which means structured information is dropped after some time (memory buffer only holds few hours back). To see structured fields:
journalctl -fo verbose
Here is the list of most important structured fields which can help with debugging:
Journald name | JSON name | Description |
---|---|---|
USER_LOGIN | ["mdc"]["user_login"] | User login name |
ORG_ID | ["mdc"]["org_id"] | Organization database ID |
LOC_ID | ["mdc"]["loc_id"] | Location database ID |
REMOTE_IP | ["mdc"]["remote_ip"] | Remote IP address of a client |
REQUEST | ["mdc"]["request"] | Request ID generated by ActionDispatch |
SESSION | ["mdc"]["session"] | Random ID generated per session or request for session-less request |
EXCEPTION_MESSAGE | ["ndc"]["exception_message"] | Exception message when error is logged |
EXCEPTION_CLASS | ["ndc"]["exception_class"] | Exception Ruby class when error is logged |
EXCEPTION_BACKTRACE | ["ndc"]["exception_backtrace"] | Exception backtrace as a multiline string when error is logged |
TEMPLATE_NAME | ["ndc"]["template_name"] | Template name (blob logger) |
TEMPLATE_DIGEST | ["ndc"]["template_digest"] | Digest (SHA256) of rendered template contents (blob logger) |
TEMPLATE_HOST_NAME | ["ndc"]["template_host_name"] | Host name for a rendered template if present (blob logger) |
TEMPLATE_HOST_ID | ["ndc"]["template_host_id"] | Host database ID for a rendered template if present (blob logger) |
AUDIT_ACTION | ["ndc"]["audit_action"] | Action performed (e.g. create/update/delete) |
AUDIT_TYPE | ["ndc"]["audit"] | Database model class or type, subject of an audit record (e.g. Hostgroup or Subnet) |
AUDIT_ID | ["ndc"]["audit"] | Record database ID of the audit subject |
AUDIT_ATTRIBUTE | ["ndc"]["audit"] | Attribute name or column an action was performed on (e.g. name or description) |
To persist structured fields, enable persistent system journal by creating /var/log/journal
directory. Alternatively, logging into JSON format can be used with syslog or file appenders for further integration:
:logging:
:level: info
:type: syslog
:json_items:
- logger
- timestamp
- level
- message
- mdc
- ndc
:facility: LOG_LOCAL6
Structured fields from Foreman appear under “mdc” and “ndc” elements. The logging stack is able to provide additional context via json_items
setting:
By default, syslog facility is set to LOCAL6 (or USER6). This can be changed via:
:logging:
:facility: LOG_LOCAL6
To forward logs to separate directory via rsyslog, create file /etc/rsyslog.d/foreman.conf
:
local6.* /var/log/foreman/production.log
Edit /etc/foreman-proxy/settings.yml
and change or add :log_level:
# WARN, DEBUG, Error, Fatal, INFO, UNKNOWN
:log_level: DEBUG
And restart the smart proxy:
service foreman-proxy restart
Also see Smart Proxy Settings for more information.
The two primary methods of getting support for Foreman are IRC and discussion forums.
We work on the libera.chat servers. You can get general support in #theforeman, while development chat takes place in #theforeman-dev.
An online discussion forum is available at https://community.theforeman.org/. Much like IRC, we have discussion areas for general users (support, Q/A, etc), as well as a discussion areas for developers, tutorials and release announcements.
In order to troubleshoot and get relevant data use foreman-debug which collects information about your OS, Foreman and related components. If you installed from packages, the command is available to root:
# foreman-debug
If you installed from git, you can find it in the Foreman directory:
# script/foreman-debug
If you run it without any options, it will collect data, filter out possible passwords or tokens and create a tarball which can be safely handed over to us.
To upload the tarball to our public server via rsync use:
# foreman-debug -u
This is a write-only directory (readable only by Foreman core developers), please note that the rsync transmission is UNENCRYPTED.
Foreman 3.12.0 has been released! Follow the quick start to install it.
