Setup

Docker for Mac lets you run any Linux executable in an isolated process on Mac. A graphical app is just another process, that needs access to the X11 socket of the system, or an X11 server. You can run X11 applications on a Mac using an open source project called Xquartz. The steps to expose XQuartz to a Linux process running in Docker are simple:

1. install XQuartz from xquartz.org. Note: you need to install XQuartz version 2.7.10, version 2.7.11 does not work with Docker for Mac. Then you have 3 choices:
2. Proxy the XQuartz socket to port 6000 or
3. Tell Xquartz to accept network calls. This is not very secure.
4. Tell Xquartz to accept network calls and require authentication, setup X11 security using xauth, and mount ~/.Xauthority in the container.

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

1. Install XQuartz: https://www.xquartz.org/
2. Launch XQuartz. Under the XQuartz menu, select Preferences
3. Go to the security tab and ensure "Allow connections from network clients" is checked.
4. Run xhost + ${hostname} to allow connections to the macOS host *
5. Setup a HOSTNAME env var export HOSTNAME=`hostname`*
6. Add the following to your docker-compose:
