PuppetConf 2016

Introducing containers into your infrastructure brings new capabilities, but also new challenges, in particular around configuration. This talk will take a look under the hood at some of those operational challenges including: * The difference between runtime and build-time configuration, and the importance of relating the two together. * Configuration drift, immutable mental models and mutable container file systems. * Who configures the orchestrators? * Emergent vs. model driven configuration. In the process we will identify some common problems and talk about potential solutions. And we'll show some demos along the way too.
