x11 custom network

[nickollasaranha]

Is it possible to connect to x11 server without using the --net=host argument? I've created my own sub network with docker network create and would like to run the cosmos image with:
docker run --net mynetwork --ip 172.18.0.30 -e DISPLAY -e QT_X11_NO_MITSHM=1 ballaerospace/cosmos

It should work without --net=host. I think that is for being able to talk to COSMOS from outside of Docker, more than making X11 work. You'll have to port map the COSMOS ports, if you want to connect to COSMOS from something outside of Docker.

Give it a try and let us know if you have any issues.

Make sure you DISPLAY variable has a full IP address (not localhost/127.0.0.1) that Docker can reach
