I just made a switch from Kube to Kontena last week. I had constant trouble with etcd cluster and so far Kontena seems solid and was much faster to set up for production. I'm running 6-8 nodes so kube always felt like it was a little too much for me.

I noticed the same thing about FAQ, I had all those working in my kubernetes setup.

I had no problems setting up or managing Kubernetes though I share the sentiment that Kubernetes feels like a little overkill.

One problem I did have with Kubernetes was upgrading. In the 1.3 era, I used kube-up to spin up an AWS cluster. There was no upgrade path until 1.5 when Kops began supporting importing kube-up clusters. It almost worked automatically, but it somehow got the wrong setting for one of the subnet configurations. Once I fixed that though, it worked. I gotta admit I was pretty impressed.

The only other problem I can think of is security, everything inside Kubernetes currently defaults to having full API permissions. Obviously this is insane pants-on-head behavior.

Security in general is a bit lacking in k8s, though with RBAC in 1.6 and encrypted Secrets in 1.7, it seems they are working hard to make things better.

In GKE I just use one cluster per permission domain, which is fine for one team (and 2-3 permission domains), but obviously for large orgs would be a massive headache.
