Preamble

There is a longstanding issue/missing feature/bug with sockets on Docker on macOS; it may never work; you'll need to use a network connection between Docker containers and X11 on macOS for the foreseeable future.

I started from this gist and made some adjustments:

• the volume mappings aren't relevant/used, due to the socket issue above.
• this method only allows X11 connections from your Mac, not the entire local network, which would include everyone on the café/airport WiFi.
• updated to include using the host.docker.internal name for the the container host, instead.
• you have to restart XQuartz after the config change.

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:

 environment:

# Dont forget to set the env variable "certdomain", and either fill in your email below or use an env variable for that too.
# Also note that this config is using the LetsEncrypt staging server, remove the flag when ready!
