Docker Setup

If your operating system doesn't support ROS 2 humble, docker is a great alternative.

First of all, you have to build the project and create an image like so:

## Assuimg you are in the correct project directory
docker build -t gmg .

## Assuimg you are in the correct project directory
docker run -it --net=host --ipc=host --privileged --env="DISPLAY"  --env="QT_X11_NO_MITSHM=1" --volume="/tmp/.X11-unix:/tmp/.X11-unix:rw" --volume="${XAUTHORITY}:/root/.Xauthority"  --entrypoint /bin/bash gmg

To use a shortcut, you may use following command:

make docker_run
