Puppet Configuration and Administration – 3 Days

Basic / Intermediate Concepts and Techniques

Course Description

This course presents the system management and configuration tool Puppet Enterprise 5, from methods, techniques, capabilities to implementation.  Each participant will learn how to install the Puppet master and agent (client) applications along with the impact on the RHEL 7 system.  A lot of time and attention will be spent in learning, writing, and applying resource definitions, the key part of Puppet that allows an administrator to synchronize environments easily and uniformly.

Implementation

Each participant will have a dedicated RHEL 7 virtual server for Puppet Enterprise installation, resource definition writing and application.  A second  RHEL 7 virtual system will be setup as the Puppet agent. The system will also be used as a masterless Puppet configuration.
