The Puppet agent-to-server lifecycle

This section will look at how the Puppet agent makes requests to the Puppet server components we have run through and how it secures its communications before requesting configuration to enforce from the Puppet servers. It should be noted the Puppet servers themselves also contain Puppet agents.

The installation of Puppet agents is detailed at https://puppet.com/docs/puppet/latest/install_agents.html#install_agents for open source and https://puppet.com/docs/pe/2021.7/installing_agents.html#installing_agents for PE. Integrating this install with your server deployment workflow and ensuring the necessary configuration is placed at /etc/puppetlab/puppet.conf is critical for automation.

Note

The puppet_conf module provides tasks to manage Puppet configuration files (https://forge.puppet.com/modules/puppetlabs/puppet_conf).
