Your Puppet manifests are the living documentation for your entire infrastructure. Keeping them tidy and well-organized is a great way to make it easier to maintain and understand. Puppet gives you a number of tools to do this:
- Arrays
- Defaults
- Defined types
- Dependencies
- Class parameters
We'll see how to use all of these and more. As you read through the chapter, try out the examples and look through your own manifests to see where these features might help you simplify and improve your Puppet code.
