Add bash docker_runner.sh before your python command. The script will pass everything followed into the docker. For Pacman, you can run a simple game with the following commands. Please run this in your repo's root directory.
bash docker/docker_runner.sh
And then you can run the game following the instruction. Please use option -t to make sure only use textDisplayer. You might need to use -p options if you want to see the print in terminal, or use -l option to save the output into a log file.
You might need to use superuser (adminstrator) access to run this.
Docker related parameters are included in the docker/docker_config file. If you want to rebuild your image with new requirements.txt, you can switch force_build to 1.
You can use the second docker_cmd in docker_runner.sh to debug in the container. Use exit to stop debugging.
