Docker for GUI-based environments?

Question

Problem

I have a set of client machines that are a part of an enterprise web application. Each machine runs identical software, which is a PyQT-base

Answer 1

There are many solutions to have GUI apps running in a docker container. You can use SSH, or VNC for instance. But they add some overhead and delay. The best way that I found is just to pass in the file used by the X server in the host machine as a volume to the container. Like this:

docker run -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY TheImage

Then all your GUI apps will run from container.

Hope This helps!
