Google Container Engine supports cluster autoscaling to automatically add nodes with load. It's listed as a beta feature though.

I've tried most of the Docker orchestration offerings and Container Engine seems by far the nicest. Swarm and Compose are really simple for getting up and running, but when we evaluated them there was still a missing piece required in that there was no neat way to do zero downtime deployments.

There's a tool called Kompose to convert docker-compose config to kubernetes manifests (https://github.com/kubernetes-incubator/kompose) although whilst it's nice to get you started we tend to maintain them separately now.
