See the Foreman manual for general information on configuring provisioning.
Katello ships a number of templates in addition to the standard Foreman ones. When using these templates, if a host has a Host group with an Activation Key, it will register as a Content Host automatically.
To customize any of the above templates, simply clone them and add your changes.
When you synchronize a repository with a distribution such as Fedora or CentOS, Katello will automatically create the operating system and assign these default templates. You may change the defaults by going to Administer > Settings, and selecting the Katello tab.
A new bug fix release for Foreman 1.15 is available. See the Foreman 1.15.1 release notes for more details.
Foreman 1.15.0 is now available, featuring a new notifications UI, template changes, and improvements to host owners and SSH keys. Read about all of the changes in the release notes, and follow the quick start to install it.
