"""
Ansible module for determining information about the docker host.

While there are several ansible modules that make use of the docker
api to expose container and image facts in a remote host, they
are unable to return specific information about the host machine
itself. This module exposes the same information obtained through
executing the `docker info` command on a docker host, in json format.
