Have you looked at Docker for AWS yet? https://www.docker.com/aws https://www.docker.com/aws It will setup your swarm, which uses auto scaling groups for the worker nodes. You can then configure the auto scaling groups how ever you want, to scale based on your cloudwatch metrics, etc. There is also a Docker for GCP product in beta. https://beta.docker.com https://beta.docker.com but I don't know how auto scaling works for it. Disclaimer: I work at Docker on the Docker for AWS product.
