====== Docker Quick How-to ======
Well, I use Debian. A lot of things use Ubuntu. For the sake of laziness, I decided to use Docker to run an Ubuntu image. Originally, I installed docker to run Pokemon Go bots.

===== Basic commands =====
  * List running docker processes
  ''docker ps''
  * List all docker containers
  ''docker ps -a''
  * Instantiate an Ubuntu docker instance
  ''docker run -it ubuntu:16.04 /bin/bash''
  * Run docker with GUI support
  ''docker run -it -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix /bin/bash''
  * Restart a docker instance
  ''docker start -a -i 9bb21badced9''
  * Clear all stopped docker instances
  ''docker rm `docker ps --no-trunc -aq`''

===== Run Docker with GUI support =====
Please note that **you cannot run xterm as root**.
<code bash>
docker run -it --env="DISPLAY" --env="QT_X11_NO_MITSHM=1" --volume="/tmp/.X11-unix:/tmp/.X11-unix:rw" ubuntu:16.04 /bin/bash
</code>

===== Running Docker with GPU support =====
<code bash>
docker run -it --env="DISPLAY" --env="QT_X11_NO_MITSHM=1" --volume="/tmp/.X11-unix:/tmp/.X11-unix:rw" --device /dev/nvidia0:/dev/nvidia0 --device /dev/nvidiactl:/dev/nvidiactl --device /dev/nvidia-uvm:/dev/nvidia-uvm ubuntu:16.04 /bin/bash
</code>
