We’re all familiar with the Puppet manifest development cycle: “make your change, commit your change, push your change, run Puppet, debug the output, then go back to the beginning to refactor or fix a bug”. What if you could could shorten the cycle to “make a change, run puppet, commit change”? Enter Rump, a tool for doing Puppet runs locally from a Git checkout. Rump encourages a Puppet workflow where you quickly + iteratively develop your Puppet manifests on a single machine, then push your changes up to a repository to deploy to the rest of your infrastructure. Lindsay will be demonstrating how to setup Rump, showing off some awesome workflows for doing local iterative development, and exposing super cool features like testing your manifests against new versions of Puppet in a single command.
