I assume the topic is Docker orchestration to automatically start/stop/restart/kill/roll upgrade/canary/bluegreen the servers.

If you are on AWS, use auto scaling groups. It achieves more than these software, it works and it's stable. (Bonus: you don't need docker at all).

If you are on GCE, use Google Container Engine (i.e. their kubernetes). That's the only [sane] way to have kubernetes running in production.

I'm planning a blog post about all that later.
