In an ideal world, we would be able to provision our hosts and have things work consistently without problems every day ― but that is not the case because a system that is completely immune to all issues does not exist. In this hands-on lab, we explore the reasons why a node with the Puppet agent is unable to connect to our Puppet master. We will start this lesson by ensuring that there are no connection issues overall and then explore using the certificate authority to confirm if any conflicting certificates are preventing the node from connecting. Once the problem is tracked down, we will take the appropriate steps to fix the communication issue and connect our node to the Puppet master.

What are Hands-On Labs?

Hands-On Labs are scenario-based learning environments where learners can practice without consequences. Don't compromise a system or waste money on expensive downloads. Practice real-world skills without the real-world risk, no assembly required.
