The docker image can be built by executing
docker build -t sobot-rimulator .
However, in order to run the GUI application, some additional effort is required, so that the docker dontainer may access the display of the host machine.
The following setup is based on the blog post https://cntnr.io/running-guis-with-docker-on-mac-os-x-a14df6a76efc, where you can find more detailed explanations.
Install socat and start listening:
brew install socat
socat TCP-LISTEN:6000,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\"
Open a new terminal and install XQuartz:
brew install xquartz
Determine the IP address of your host machines network interface
IP=$(ipconfig getifaddr en0)
Run the docker image by setting the DISPLAY environment variable to your IP address
docker run -e DISPLAY=$IP:0 sobot-rimulator
After building the image, the container must be allowed access to the display and can then be run
$ xhost +local:root
$ docker run -e DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix sobot-rimulator
