Code Manager and r10k
PE includes tools for managing and deploying your Puppet code: Code Manager and r10k.
These tools install modules, create and maintain environments, and deploy code to your primary servers, all based on code you keep in Git. They sync the code to your primary servers, so that all your servers start running the new code at the same time, without interrupting agent runs.
Both Code Manager and r10k are built into PE, so you don't have to install anything, but you need to have a basic familiarity with Git.
Code Manager comes with a command line tool which you can use to trigger code deployments from the command line.
