Preface
This book is for anyone using or considering Puppet as a systems automation tool. Readers of this book should be familiar with Linux systems administration and basic Ruby. I’ll cover the basics of using Puppet manifests for configuration management and techniques for executing and managing those configurations with MCollective and Facter. I’ll often make suggestions that assume you are managing a virtualized infrastructure, but virtualization is not necessary to reap the benefits of this software.
Software
This book is focused on Puppet 2.6.1 with Facter 1.5.6, and the MCollective version used is 1.0.1. Because of the very active development of all of these products, concepts and examples may not apply to earlier versions.
