-If there is no database when `postgres` starts in a container, then `postgres` will create the default database for you. While this is the expected behavior of `postgres`, this means that it will not accept incoming connections during that time. This may cause issues when using automation tools, such as `fig`, that start several containers simultaneously.

 `swarm` is a simple tool which controls a cluster of Docker hosts and exposes it as a single "virtual" host.
 
-`swarm` uses the standard Docker API as its frontend, which means any tool which speaks Docker can control swarm transparently: dokku, fig, krane, flynn, deis, docker-ui, shipyard, drone.io, Jenkins... and of course the Docker client itself.

 Like the other Docker projects, `swarm` follows the "batteries included but removable" principle. It ships with a simple scheduling backend out of the box, and as initial development settles, an API will develop to enable pluggable backends. The goal is to provide a smooth out-of-box experience for simple use cases, and allow swapping in more powerful backends, like `Mesos`, for large scale production deployments.
