What is the primary function of the Puppet Agent?

The primary function of the Puppet Agent is to enforce configurations on the node. This means that the Puppet Agent is responsible for applying the desired state of the system as defined in Puppet manifests. It does this by communicating with the Puppet Master (or Puppet Server), retrieving the configuration data, and then applying those configurations to the local system.

When the Puppet Agent runs, it checks the current state of the resources on the node against the desired state specified in the Puppet manifests. If discrepancies are found, the Puppet Agent will make the necessary changes to ensure that the node matches the desired configuration, thus maintaining system compliance and configuration management. This proactive enforcement ensures consistency across systems within an infrastructure, which is a critical aspect of using Puppet effectively.

In contrast, defining resources, reporting on statuses, and installing Puppet modules are important tasks within the Puppet ecosystem, but they do not represent the primary function of the Puppet Agent itself. The agent focuses primarily on enforcing the desired configurations specified by the manifest files.
