A class with the same name as the module goes into which file?

The class with the same name as the module is typically defined within the init.pp file located in the manifests directory of a Puppet module. This is a convention in Puppet, where the init.pp file serves as the entry point for defining the primary class of the module.

When Puppet loads a module, it looks for the init.pp file to find the main class that corresponds to that module name. This structure allows for better organization and clarity within the module, making it easier for users to understand the purpose of the module and how to use it. By convention, having the main class in init.pp helps ensure that the class can be accessed by its module name without needing to specify a different path, which aligns with Puppet’s design philosophy of simplicity and ease of use.

Other file options like lib/self.pp, self.pp, and manifests/class do not adhere to the standard Puppet module structure for defining the main class. They either do not exist within the typical Puppet module layout or serve different purposes in the context of Puppet’s architecture.
