And Docker bought Fig, so it is likely it will continue to be supported and eventually even do multi-host container orchestration.

I'm really excited about the idea of groups that may be coming to Docker. It seems like a great primitive around which to build tools like fig and tug and perhaps other tools to orchestrate production.

Except Docker said Fig is a dead end and that its functionality would be integrated into `docker` itself.
