第7章 Using Config Groups to Manage Puppet Classes

Red Hat Satellite includes the concept of Config Groups and Host Groups to enable building and managing groups of systems in a modular way.

Config Groups are a collection of Puppet classes that you create to form building blocks for use in configuring Hosts and Host Groups. Config Groups are analogous to the community Puppet concept of Profiles, a Puppet class that includes a collection of Puppet classes to form a building block. Config Groups can be created and managed in the Satellite web UI.

Host Groups are both a collection of host servers and a container for the definition of a system, with a Content View, an assigned life cycle, and a set of Puppet modules. Host Groups are analogous to the community Puppet concept of Roles, a Puppet class that includes a number of Profiles to build a system with a specific business role. Host Groups can be created and managed in the Satellite web UI, using the Hammer CLI, and by using the API.

Navigate to Configure > Config groups.

Select New Config Group and enter a name, for example, TestConfGroup.

Select one or more Puppet Classes from the list of available classes.

Select Submit to apply the changes.

Once you have created a Config Group it will be available for selection on the Puppet Classes tab when configuring a Host or Host Group. For more information on creating Host Groups see Creating a Host Group on Satellite Server in the Red Hat Satellite Provisioning Guide.
