The setup that's required varies depending on your operating system.
=== Docker on OS X
The latest version of Docker runs as a native Mac application but isn't supported by
docker-java. This means that you should use Docker Toolbox. See the

== Preparing to run the tests
Before running the tests, you must prepare your environment according to your operating

=== Preparation on OS X
The tests must be run in an environment where various environment variables including
`DOCKER_HOST` and `DOCKER_CERT_PATH` have been set:

=== Preparation on Linux
Docker Daemon's default configuration on Linux uses a Unix socket for communication.
However, Docker's Java client uses HTTP by default. Docker Java's client can be configured
to use the Unix socket via the `DOCKER_URL` environment variable:
----
$ export DOCKER_URL=unix:///var/run/docker.sock

If you want to reclaim the disk space used by the cached images (at the expense of having
