Unofficial "Dr. Robotnik's Ring Racers" Dockerfile

Note: This repository doesn't contains any final image, you can follow the guide below.

Build image

Note: The built image will use the "master" branch of RR on the KartKrew repository

Clone this repository and move into it, then run this command with the arguments you need :

docker build \
	--build-arg="RR_TAG=v2.2" \
	--build-arg="RR_PORT=5029" \
	--build-arg="ADVERTISE=Yes" \
	-t=ringracers-server .

All availables build arguments, :

Note: Only the RR_TAG is useful for building the image, it is not for running the container

Run container

Run this command after building the image :

docker run -i -t -d \
	--name=ringracers.server \
	-v "/path/to/some/folder/on/host:/home/ringracers/.ringracers/" \
	-e RR_PORT=5029 \
	-e ADVERTISE=Yes \
	-p 5029:5029/udp \
	--health-cmd='./entrypoint.sh monitor' \
	--health-interval=30s \
	--health-start-period=5s \
	ringracers-server

You can change the healthcheck values if you want to restart the server if it has crashed.
You'll need to match the RR_PORT (you can set it during build or during running) to the port in the -p 5029:5029/udp argument, the one to the right in the argument.

Access game console

You can acces the game console with this command : docker exec -i -t ringracers.server tmux attach
To detach from the console without closing the server, press Ctrl+B then D (see tmux manual on this).
