Configuration Management with Puppet: Part 1

Abstract

The idea is to give the participants first an idea about the puppet language. Next we show how to use puppet in the client/server setup but without git.

we will create for all participants local environments on the puppetmaster where they can create their manifests.

They also have to create locally the node definitions on the puppetmaster.

Before Step 8 we change the puppetmaster configuration, to a git-o-lite setup.

Before Step 10 we change the puppetmaster configuration, to use a ENC
