How to use this image

The image exposes ports 2759 (server) and 2757 (server discovery). The server should be configured using your own server config file. The config file template can be found here. Modify it according to your needs and mount it at /stk/server_config.xml:

Hosting a server in your local network

docker run --name my-stk-server \
           -d \
           -p 2757:2757 \
           -p 2759:2759 \
           -v $(pwd)/server_config.xml:/stk/server_config.xml \
           jwestp/supertuxkart:latest

Hosting a server on the internet

For hosting a server on the internet (by setting wan-server to true in the config file) it is required to log in with your STK account. You can register a free account here. Pass your username and password to the container via environment variables.

docker run --name my-stk-server \
           -d \
           -p 2757:2757 \
           -p 2759:2759 \
           -v $(pwd)/server_config.xml:/stk/server_config.xml \
           -e USERNAME=myusername \
           -e PASSWORD=mypassword \
           jwestp/supertuxkart:latest

Adding ai karts

You can add ai karts to your server by setting the environment variable AI_KARTS like shown in the following example:

docker run --name my-stk-server \
           -d \
           -p 2757:2757 \
           -p 2759:2759 \
           -v $(pwd)/server_config.xml:/stk/server_config.xml \
           -e USERNAME=myusername \
           -e PASSWORD=mypassword \
           -e AI_KARTS=4 \
           jwestp/supertuxkart:latest

Accessing the network console

You can access the interactive network console with the following command:

docker exec -it my-stk-server supertuxkart --connect-now=127.0.0.1:2759 --network-console

If your server is password secured use the following command:

docker exec -it my-stk-server supertuxkart --connect-now=127.0.0.1:2759 --server-password=MY_SERVER_PASSWORD --network-console

Using docker-compose

Clone this repository and have a look into the docker-compose.yml to edit your credentials (username & password). If you want to run a public server without needing a password, you can remove the environment section with its corresponding entries. After editing, you can get the server up and running by doing a docker-compose up -d. Have a look at the logs by using docker-compose logs This can be especially useful when searching for bugs.
