    To forward X11 from inside a docker container to a host running macOS


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}
