What is the role of a Puppet manifest?

The role of a Puppet manifest is primarily to declare resources and their desired state. In Puppet, a manifest is a file that contains a series of declarations that specify how a system should be configured. These declarations include various resources such as packages, services, files, users, and more, along with the states that these resources should be in.

For example, a manifest might specify that a certain package should be installed, a service should be running, or a particular file should have specific content. By defining these resources and their states within a manifest, Puppet ensures that the system configuration is consistently applied and maintained across nodes, allowing for efficient configuration management.

While managing user permissions, logging agent runs, and monitoring system performance are important tasks in system administration, they are not the primary role of a Puppet manifest. User permissions can be managed through resource declarations within a manifest, but this is just a subset of the broader functionality manifest files provide.
