Container Factory vs. dockersh vs. Flocker

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.

dockersh is designed to be used as a login shell on machines with multiple interactive users. When a user invokes dockersh, it will bring up a Docker container (if not already running), and then spawn a new interactive shell in the container's namespace.

Flocker is a data volume manager and multi-host Docker cluster management tool. With it you can control your data using the same tools you use for your stateless applications. This means that you can run your databases, queues and key-value stores in Docker and move them around as easily as the rest of your app.
