dockit, or "Docker Tookit", was inspired by toolbox by debarshiray. dockit is designed to be simple and more cross-platform than toolbox.
Copy dockit to a location in your path and grant it +x.
dockit will create a Docker container that maps your home directory to /root. At this time dockit uses the Fedora image from Docker Hub. If there's interest, flags for other images can be incorporated.
