`Docker <https://en.wikipedia.org/wiki/Docker_(software)>`_ is a virtualization software that let's
you run software in a container, bundled with needed libraries and configuration files.

.. warning::

    If you never heard of it, you should ask someone to explain it to you or look at tutorials like the `german docker tutorial by Morpheus <https://www.youtube.com/watch?v=avdVAfL8GPI>`_. This guide will not cover it.

Basic commands
==============

* :code:`docker ps`: Will list all running containers with associated information
* :code:`docker system prune`:  Will remove all stopped containers, all networks not used by at least one containers and all dangling images
* :code:`docker exec -it CONTAINER_NAME sh`: Executes a command, here ``sh`` (a shell) in interavtive mode in the container with ``CONTAINER_NAME``
