HA containers for us means smart orchestration tools. We did not want to lock ourselves into Docker-only infrastructure (even now rkt is a very compelling alternative), and wanted an orchestrator/scheduler that is focused entirely on that job. Outside of Swarm, Mesos & co appeared too intrusive, and Nomad is quite narrow in what it does. So we picked Kubernetes and are very happy with it.
