Summary
In this chapter, you learned about declaring resources and the syntax and styling checks that can be performed to develop consistent code. Classes were shown to be a way to group resources and allow us to call classes and apply these groups of resources to servers. Defined types were then shown as a way to create repeatable patterns of Puppet code, which can vary by parameters.
We showed how to explore and use types and providers and saw some of the most commonly used core types and how to use them well. The file, package, and service types were shown to provide a great foundation for installing, configuring, and starting an application. It was seen how Puppet resources can relate to each other to ensure an order and how to then apply these resources written locally to servers for testing.
The chapter covered the core resource metaparameters to understand how to use various features of resources – tagging to allow filtered runs of resources; auditing to monitor...
