Chapter 2. Introduction to Puppet
Puppet is an open source configuration management utility produced by Puppet Labs®. You can define system configurations using Puppet's declarative language and store them in files called Puppet manifests, which use the
.pp file extension.
Puppet can be run standalone on a system or used in an agent/master configuration. With standalone Puppet, systems run Puppet locally to apply their own configurations. With agent/master Puppet, a central Puppet master server or servers manages multiple systems running the Puppet agent. For either implementation, Puppet manifests are used to bring system configurations to the desired state. A commercial offering, Puppet Enterprise®, is also available from Puppet Labs®.
Note
Installation and configuration of Puppet is left to your discretion. While any of the Puppet implementations or products described above can be used to deploy OpenShift Enterprise 2.2, this guide covers standalone Puppet usage.
See the Puppet Labs® documentation [1] for more information on Puppet, including instructions for installing agent/master or standalone Puppet [2] or installing Puppet Enterprise® [3].
