How does Puppet apply configuration to agent nodes

Question

I've recently started learning Puppet and I'm unable to understand how puppet works. What is its workflow? How does it manage the configurations of agent nodes?

Answer 1

Puppet follows this workflow:

• There is a factor present on all the agent nodes. Puppet master collects the details of these agent nodes through factor. It gets all the machine level configurations of these agent nodes.
• Next, it compares with the collected configuration with defines configuration and creates a catalog about what other changes are needed. This catalog is then sent to all the agent nodes.
• These agent nodes then apply these catalog mentioned configuration changes to their system to achieve the desired configuration.
• Finally, when the agent nodes have achieved the desired configuration, it sends a success message and the report to the master.
