Overview

Puppet provides a central facility to manage a network of computers with different architectures and different operating systems. Systems administrators need only specify the desired state of the systems and Puppet will ensure that each node remains in or returns to the desired state. This provides high reliability and easy recoverability. It also makes it easy to build multiple systems with the same configuration.

This course has a high hands-on content so that participants can apply the theoretical concepts.

Objectives

On successful completion of this course, participants will be able to:

  • Understand the Puppet architecture
  • Deploy system configurations using best practices in a master/agent network
  • Install puppet and its dependencies
  • Configure the master and agent nodes
  • Understand Puppet resources, classes, defined types and nodes
  • Use features of the Puppet DSL
  • Use different methods of node classification
  • Write and install module-based manifests
  • Understand the differences between the Open Source and Enterprise versions
  • Use MCollective for orchestration

Audience

This course is for Unix and Linux systems administrators who wish to use Puppet to manage their configurations.

Prerequisites

Experience of Unix and/or Linux systems administration, up to the level covered in the Unix System Administration course is assumed. Familiarity with Ruby is an advantage but not essential as the relevant features of the language are introduced where necessary in the course.
