Local X11 server
docker run -it --rm -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix jarfil/gimp-git
Remote SSH into docker host, low isolation
docker run -it --rm --net=host -e DISPLAY=$DISPLAY -v $HOME:/hosthome:ro -e XAUTHORITY=/hosthome/.Xauthority jarfil/gimp-git
You can also install sshd onto the image and ssh directly into it.
To automate the image building process with reasonable throttle enforcement, there is a web trigger available.
