Which file type is typically used for Puppet module metadata?

The typical file type used for Puppet module metadata is .json. Puppet modules require a specific structure in order to provide metadata that defines aspects such as version, dependencies, and other module-specific characteristics. This metadata is stored in a file named metadata.json.

Using JSON for metadata allows for structured data representation, making it easier for both machines and humans to read and understand. The process of parsing JSON is also efficient, which is beneficial for Puppet when it processes modules.

Other file types listed serve different purposes:

• The .pm extension is generally associated with Perl modules, not directly related to Puppet.

• The .yaml format is often used for configuration files in various systems, including some Puppet configurations, but it is not standard for module metadata.

• The .pp extension is utilized for Puppet manifest files, which contain the actual code that Puppet applies but does not directly represent module metadata.

Understanding these distinctions reinforces the role of each file type within the Puppet ecosystem, emphasizing the importance of using the correct format for module metadata specifically.
