== Commands used in this video ==
==== Search for available container images ====
  docker search

==== Run the Ubuntu container ====
  docker run ubuntu
Note: The container will just exit, since it needs some sort of task to run in order to stay running (as explained in the video).

==== Show running containers ====
  docker ps

==== Show all containers ====
  docker ps -a

==== Show locally downloaded images ====
  docker images

==== Run the Ubuntu container, and attach to a command prompt ====
  docker run -it ubuntu /bin/bash
Note: Since we gave it a task to perform (/bin/bash) it will stay running.

==== Install vim inside the container ====
After attaching to a bash shell within the container, run:
  apt update
  apt dist-upgrade

==== Docker containers are not stateful ====
The video shows the process of installing vim inside the container, and after exiting and relaunching the container, vim is no longer present and has to be installed again. Saving changes to containers will be discussed later on in the series.
