CoreOS and Kube are not mutually exclusive. The first k8s cluster I ever ran was on CoreOS.

Me, too! I got started with both CoreOS and kubernetes using their kubernetes-in-vagrant repo (before it went to the abysmal rkt runtime: https://github.com/coreos/coreos-kubernetes/blob/v0.4.0/mult... ) and I shepherded that v1.0.6 cluster all the way up to v1.10 when I left. It was a highly educational process

Most of our Flatcar Container Linux users run Kubernetes. It's really an ideal match for a minimal container OS.

I really prefer DC/OS to K8s. They both have strengths and weaknesses, but I hate we're not this k8s monoculture now. There need to be more container orchestration systems .. and don't kid yourself; few shops are using nomad.

Just deployed a new infra using nomad, consul & docker swarm. Much nicer than k8s

Does the uncertainty of swarm’s future not concern you? Or am I out of date?

whats the alternative? weave?

nomad, k8s, mesos+marathon (or something plus mesos), traditional deployment

That's probably about it. Right now, I'm jumping on the k8s bandwagon, but looking to keep it simple. As much as I'd like to look at nomad seriously, too many times I've been caught by not looking at the mainstream.

Yeah thats indeed true. I hope Hashicorp will develop their own overlay network tech for containers.
