This looks great, thanks for sharing -- I was planning to write something like this for my build pipeline, but having something available off-the-shelf will save a lot of time.<p>Eventually I'll be moving our Docker containers to run under Kubernetes, which might necessitate writing my own thing to replace this; I'd ultimately like to be able to deploy my k8s config files into a per-branch/per-commit namespace, so that the full deploy pipeline can be tested.
