Docker - why we shouldn't use it

There is a new hype in DevOp-Town. It is fancy, shiny and a new solution for all your problems! Well, at least that’s how most of the articles about docker sound like. The VC-backed startup made a dream start with their new open-source implementation of an LXC Interface. It promises fast startup times and deployments and some people already propagating the end of the era of configuration management.

This talk provides an short overview of the decades-old history of context isolation, what tools are still around and how Docker became so popular. Afterwards we will see in depth, why it’s far from production ready. There are serious doubts about this technology, including serious security issues, container propagation, maturity, configuration management and many more.

It finishes with general thoughts about provisioning vs. deployment in a broad sense. I will introduce how we want takle this problem and how I would love to handle server orchestration in the future.
