From the other replies here, it sounds like what kubernetes does for most people is what people used to do with bash scripts in the past: automatic configuration and deployment of sets of Phoenix servers (except in containers instead of vms these days) with infrastructure as code. The main difference sounds like you write declaratively and you get to use yaml. It seems to throw in monitoring and control too, which seems like a timesaver. Is that about right?
