Introduction

Puppet is a useful tool by itself, but you can get much greater benefits by using Puppet in combination with other tools and frameworks. We'll look at some ways of getting data into Puppet, including custom Facter facts, external facts, and tools to generate Puppet manifests automatically from the existing configuration.

You'll also learn how to extend Puppet by creating your own custom functions, resource types, and providers; how to use an external node classifier script to integrate Puppet with other parts of your infrastructure; and how to test your code with rspec-puppet.
