Overview

Our environment is currently using Puppet v3.8.7 - Documentation

The current Puppet environment is running on a single instance server. We are not sure yet if we will stick with Puppet or switch to Ansible (or Ansible Tower), but in the mean time, it was decided that making the existing Puppet environment more resilient would be a good idea.

There is a group of Puppet clients that need to be upgraded before we can point them to the new Puppet Master.

Autosigning appears to be enabled on the new Puppet Master. I think we might want to adjust this at some point. It's considered insecure to enable naive auto-signing : documentation. Currently, the autosign.conf file contains "*" which I understand to mean that EVERYONE is allowed to have their CSR auto-signed.
