Testing Puppet feature environments with Puppet Bolt

Puppet feature environments are an excellent way to test code before deploying it, typically to production. They allow testing Puppet runs on no-operation mode across the whole node population managed by Puppet. There are sometimes cases where your code changes potentially impact many nodes and you're not exactly sure of their scope or effect. In […]

The four ways to install Puppet modules

When working with Puppet and Puppet modules in particular you quickly notice that there are several ways to manage module dependencies.

Some tools […]

In the previous post I discussed the control repository structure. In this post I'll talk about r10k. That tool is used for deploying control repository branches into matching Puppet environments on the Puppet server. Installing r10k is very straightforward with the bundled gem: After this you'll need a settings file for r10k, /etc/puppetlabs/r10k/r10k.yaml: Several requirements […]

Fattening the Puppet workflow, part 1: The control repository

If editing Puppet code and Hiera directly with puppetmaster feels too easy, you can complicate the Puppet workflow as much you like by adding more components to the palette. Adding the so called control repository and r10k to Puppet environment maintenance instantly adds several phases to your initially simple workflow. There are also benefits that […]

Managing Jenkins with Puppet, part 1: Basic installation

Puppet is, if not the de facto configuration management solution, at least one of the […]
