Kubernetes vs. Docker Swarm vs. Container Factory

Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.

Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.

container-factory produces Docker images from tarballs of application source code. It accepts archives with Dockerfiles, but if your application's language is supported, it can automatically add a suitable Dockerfile.
