Using docker to run SC2 bots
This is a small overview on how to use docker to run 2 bots (here: python-sc2 bots) against each other using the linux binary SC2 client. For a quick summary of commands, scroll to the bottom.
Requirements
Docker installed and running
Internet
Doesn’t require a GPU
Pulling the Docker image
The SC2 AI community has decided to stay on Python3.9 for a while. I’ll try to update the docker image as soon as a new linux binary is released, or create a pull request at https://github.com/BurnySc2/python-sc2-docker
docker pull burnysc2/python-sc2-docker:release-python_3.9-sc2_4.10_arenaclient_burny
Deleting previous containers
To remove the previously used app container:
docker run -it -d --name app test_image
Launching a new container
The following command launches a new container in interactive mode, which means it will not shut down once it is done running:
docker run -it -d --name app burnysc2/python-sc2-docker:release-python_3.9-sc2_4.10_arenaclient_burny
Install bot requirements
The command docker exec -i app poetry add "burnysc2>=0.12.12" installs the burnysc2 dependencies in the docker container. Add more libraries as needed. You can also create your custom docker image so you do not have to re-install the dependencies every time you create a new container.
Since the linux SC2 binary is usually outdated (last update as of this writing was summer of 2019), you will likely have to replace your IDs with older IDs, which can be found here: https://github.com/BurnySc2/python-sc2/tree/linux-4.10/sc2/ids
If you want your bots to play against a compiled bot (.exe), you will have to install wine. I have not included wine in the docker image to keep the image as small as possible.
Copying Bots to the container
The bots in the container need to be located under app:/root/StarCraftII/Bots/<bot_name>
A copy command could be docker cp examples/competetive/. app:/root/StarCraftII/Bots/my_bot if you are in the main python-sc2` directory, which copies the competetive example bot to the container. The bots will be launched via ``run.py. The ladderbots.json might not be needed.
Don’t forget to copy the python-sc2/sc2 folder, or else an older version might be used (on import) and your bot might not work correctly.
For more info about competitive bots setup, see:
https://github.com/BurnySc2/python-sc2/tree/develop/examples/competitive or https://eschamp.discourse.group/t/simple-starcraft-2-bot-template-to-get-started/155
Copying the runner to the container
You will have to configure the custom_run_local.py file (ctrl+f for def main()).
It can be found here: https://github.com/BurnySc2/python-sc2/blob/fa4933a1bf89540a052482b1a394c8d6206d7491/bat_files/docker/custom_run_local.py
You may also customize the arenaclient settings.json (e.g. max game time) which is located under /root/aiarena-client/arenaclient/proxy/settings.json
Click here to check which settings are available: https://github.com/BurnySc2/aiarena-client/blob/a1cd2e9314e7fd2accd0e69aa77d89a9978e619c/arenaclient/proxy/server.py#L164-L170
After you are done customizing which matches should be played, run the following to finalize your setup:
docker cp bat_files/docker/custom_run_local.py app:/root/aiarena-client/arenaclient/run_local.py
Running the match(es)
Now you are ready to let docker run your matches (headless):
docker exec -i app poetry run python /root/aiarena-client/arenaclient/run_local.py
Copying the replay from container to host machine
To copy the results.json to the host machine to analyse the results, use:
mkdir -p temp
docker cp app:/root/aiarena-client/arenaclient/proxy/results.json temp/results.json
To copy all newly generated replays from the container, use:
mkdir -p temp/replays
docker cp app:/root/StarCraftII/Replays/. temp/replays
Summary using a shell script
For a full runner script, see:
Docker cleanup
See also: https://docs.docker.com/config/pruning/ Force removing all containers (including running):
docker rm -f $(docker ps -aq)
Removing all images:
docker rmi $(docker images -q)
Prune everything docker related:
docker system prune --volumes
