This course presents the system management and configuration tool known as Puppet, 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 Linux 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.

Learning Objectives

At the completion of the course, participants should be able to :

• install and configure Puppet servers and clients
• create and modify manifests that contain resource definitions
• create and modify classes
• create and modify modules
• create and modify node definitions
• create and modify environments
• apply manifests, classes, nodes, and environments
• extend Puppet with functions
• Use (and extend) Facter facts
• generate basic reports
• use tools MCollective, Foreman, Hiera
• design a 'best practice' strategy for using Puppet capabilities

Prerequisites

It is assumed that participants are working systems administrators with some scripting knowledge (bash, ksh, Perl or Python) and an understanding of the various system tasks relating to setting up and supporting Linux systems.

Audience

This course is for Linux systems administrators looking to automate the provisioning of key areas of the Linux system, such as packages, services, and distribution of (ssh) keys.

Implementation

Each participant will have a dedicated RHEL 6 virtual system server for Puppet installation, resource definition writing and applying. Depending upon the available resources on the host system (Windows or Mac OS X), a second RHEL 6 virtual system will be setup for the Puppet agent (client), or the server system will (also)be used as the agent (node).

Course duration

This course normally requires three (3) days, 50% lecture, with 50% hands-on commands and lab exercises.
