Puppet

Basics

Resources

A resource describes something about the state of the system, such as a certain user or file should exist, or a package should be installed.

Manifests

Puppet programs are called manifests. Manifests are composed of puppet code and their filenames use the .pp extension. The default main manifest in Puppet installed via apt is /etc/puppet/manifests/site.pp.

Classes

In Puppet, classes are code blocks that can be called in a code elsewhere. Using classes allows you reuse Puppet code, and can make reading manifests easier.

Modules

A module is a collection of manifests and data (such as facts, files, and templates), and they have a specific directory structure. Modules are useful for organizing your Puppet code, because they allow you to split your code into multiple manifests. It is considered best practice to use modules to organize almost all of your Puppet manifests.
