docker_graphics_macos

MacOS configuration to enable graphics of Docker of linux image

• XQuartz installation
• restart computer
• install Docker with your CPU version
• in the Docker application go to preferences > resources and add more memory
• X11 preference security, select "Allow connection from network clients"
• restart Docker application
• retrieve your <IP> address (inet) in a Terminal shell with:

ifconfig en0

• open a Terminal shell within the XQuartz application (only needed for this step) and add

xhost +

or

xhost <IP>

• add this option to the docker run command when creating a container

-e DISPLAY=<IP>:0

Check

python -m tkinter

Problems

If this does not work, one solution is to run socat, to forward a TCP port to a UNIX socket. You'll need to install socat, ex. brew install socat. Then, in a terminal

socat TCP-LISTEN:6001,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\"

Then run the docker, for instance

docker run -p 8888:8888 -e DISPLAY=host.docker.internal:1.0 -it --rm -v $PWD:/home grandlib/dev
