PuppetConf 2016

The UW - Madison Libraries recently began the process of rearchitecting its Linux infrastructure. This has included updating Puppet from an early version of Puppet 3 to Puppet 4 and taking a look at the entire toolchain that we use to support our configuration management and the general administration of our hosts. We've learned a few things and want to share out our experience. This talk will take a look at: * How we went about identifying anti-patterns in our Puppet code and infrastructure. * How and why we went about relearning Puppet instead of learning what had changed since we had last had time to seriously work on it. * What processes and tools we started looking at, such as testing, secret management and code deployment.
