I fully agree. Docker always felt to me like a couple of lego blocks (image repositories and a single API for managing containers on a single host), when you needed a full box like Kubernetes (auto-restarting and scaling, resource negotiation, efficient bin-packing of containers across hosts, a single API for deploying across a cluster (possibly multiple, federated), declarative description of desired runtime state with allowance for 4-eyes control of configuration, rather than a bunch of random imperative commands). Docker as a pseudo-VM where creation is incremental and intermediate states between Dockerfile lines are cached is really nifty for development, but the end result is little different than tar-ing up a filesystem after doing a clean box deployment. I think this bit is the sugar that got a lot of people hooked on Docker, even though it's not actually the good bit in the end.
