Chapter 2. Building Hosts with Puppet

In Chapter 1 we installed and configured Puppet, created our first module, and applied that module and its configuration via the Puppet agent to a host. In this chapter, we're going to extend this process to build some more complete modules and hosts with Puppet for a hypothetical company, Example.com Pty Ltd. Each host's functionality we build will introduce new Puppet concepts and ideas.

Example.com Pty Ltd has four hosts we're going to manage with Puppet: a Web server, a database server, a mail server and our Puppet master server located in a flat network. You can see that network in Figure 2-1.
