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

Here are the basic steps you need to follow get things working fine,

1. To create and run the Docker container

   sudo nvidia-docker run -it -d --privileged -e DISPLAY=$DISPLAY --name wakemeeup -v -v /dev:/dev -v /tmp/.X11-unix:/tmp/.X11-unix:rw nvidia/cuda:9.1-cudnn7-devel-ubuntu16.04 bash

2. To start the docker container

   sudo docker start wakemeup

3. To attach to the docker container

   xhost +local:root 1>/dev/null 2>&1 docker exec -u $USER -it wakemeup /bin/bash xhost -local:root 1>/dev/null 2>&1

4. The MIT-SHM is an extension to the X server which allows faster transactions by using shared memory. Docker isolation probably blocks it. Qt applications can be forced not to use the extension. Inside the docker container,

   nano ~/.bashrc export QT_X11_NO_MITSHM=1

5. Source .bashrc

   source ~/.bashrc

Hope this will help
