we canned our Kubernetes implementation after actual years of trying to glue together tools at a medium sized company with a small engineering team. we switched to Nomad and are very happy.

I am of the belief that there's an inverse bell curve of support for Kubernetes coming from 1-3 person teams and large companies. either you've got a 1-3 person engineering team who understands the whole thing, or an enterprise that can support it with a team of SREs helping keep the manifests in order. anywhere in between can become chaos quickly if you can't support training your department on it.
