Puppet manifests should always have which file extension?

Puppet manifests are scripts written in Puppet's declarative language, and they are specifically meant to define the configuration and management of systems. The correct file extension for Puppet manifests is .pp. This extension is recognized by the Puppet language interpreter when it processes the files, ensuring that the configurations contained within are interpreted correctly.

Using the .pp extension is important for clarity and organization, as it allows both Puppet and users to easily identify these files as Puppet manifests. It helps differentiate them from other script types or configuration files that might be present in a project.

For example, Python scripts typically use the .py extension, while Ruby scripts use the .rb extension. YAML files, often used for configuration settings, employ the .yaml extension. Each of these file types serves distinct purposes in different contexts, but only the .pp extension is associated with Puppet manifests specifically. Recognizing and utilizing the appropriate file extension is crucial for ensuring that your Puppet code is executed correctly and consistently within the Puppet ecosystem.
