Containers itself are a solved problem, but multi-node cluster management is still in infancy state. There are loads of tools for all kinds of situations but few that really solve hard problems. So often one is left alone with figuring out why the network is not working today, or which machine's disk has been filled with garbage etc. Openshift is one of the better packages in that regard. Kubernetes simply says "here's the api, deal with it yourself".
