- Install XQuartz: https://www.xquartz.org/
- Launch XQuartz. Under the XQuartz menu, select Preferences
- Go to the security tab and ensure "Allow connections from network clients" is checked.
- Run
xhost + ${hostname}
to allow connections to the macOS host * - Setup a HOSTNAME env var
export HOSTNAME=`hostname`
* - Add the following to your docker-compose:
environment:
- DISPLAY=${HOSTNAME}:0
volumes:
- /tmp/.X11-unix:/tmp/.X11-unix
* It should be noted that steps 4 and 5 can be automated to run everytime XQuartz starts, but that's outside of the scope of this gist
There shouldn't be a need of using "DISPLAY=host.docker.internal:0" and mounting the "/tmp/.X11-unix" socket file. I was able to make this work with just the DISPLAY envvar and enabling network connections and disabling connections auth in XQuartz settings.
Nevertheless, I think the ideal would be to just use the "/tmp/.X11-unix" file instead of network connections. I'm not being able to make this work even though the file seems to be correctly mounted inside the container.
