Sounds like docker swarm is 80% of what you want. Other than that, I think there's a reason why things like lxd, k8s (maybe joyent/smartos belong in this list)

Sounds like docker swarm is 80% of what you want. Other than that, I think there's a reason why things like lxd, k8s (maybe joyent/smartos belong in this list) - generally have one layer for the actual hw, and a higher level abstraction on top. Otoh, I suppose something like canonical metal-as-a-service might be able to do more with a little help. In fact I think maas+lxd is probably pretty close to being able to work with a compose-like tool and docker containers.
