Docker is an open-source project to easily create lightweight, portable,
self-sufficient containers from any application.  The same container
that a developer builds and tests on a laptop can run at scale, in
production, on VMs, bare metal, OpenStack clusters, public clouds and
more.

To use docker as a limited user, add your user to the 'docker' group:

  # usermod -a -G docker <your_username>

The group should be created upon installing the package, if it does not
already exist.

Adding the user to the group will require logging out and back in and also
restarting docker daemon.
