Can you run GUI applications in a Docker container?

Question

How can you run GUI applications in a Docker container?

Are there any images that set up vncserver or something so that you can - for example - add an e

Answer 1

Yet another answer in case you already built the image:

1. invoke docker w/o sudo (How to fix docker: Got permission denied issue)

2. share the same USER & home & passwd between host and container share (tips: use user id instead of user name)

3. the dev folder for driver dependent libs to work well

4. plus X11 forward.

    docker run --name=CONTAINER_NAME --network=host --privileged \
      -v /dev:/dev \
      -v `echo ~`:/home/${USER} \
      -p 8080:80 \
      --user=`id -u ${USER}` \
      --env="DISPLAY" \
      --volume="/etc/group:/etc/group:ro" \
      --volume="/etc/passwd:/etc/passwd:ro" \
      --volume="/etc/shadow:/etc/shadow:ro" \
      --volume="/etc/sudoers.d:/etc/sudoers.d:ro" \
      --volume="/tmp/.X11-unix:/tmp/.X11-unix:rw" \
      -it REPO:TAG /bin/bash

you may ask, whats the point to use docker if so many things are the same? well, one reason I can think of is to overcome the package depency hell (https://en.wikipedia.org/wiki/Dependency_hell).

So this type of usage is more suitable for developer I think.
