Configuration File #

There are many configuration options available that you can customize for your Nakama server. You can create a YML file for all configurations you want to set, and pass that file to your Docker containers.

First you will need to make a local storage volume available to Docker:

  1. Open your docker-compose.yml file in your preferred text editor.
  2. Edit the nakama:volumes: entry to specify your desired volume. For example, to create a /data folder in our desktop/nakama directory used above, which would be available at nakama/data in your Docker container, it would look like the following:
1
2

volumes:
  - ./data:/nakama/data

This will map the local ./data directory to the /nakama/data path inside the Nakama container.

  1. Save the changed file and restart your Docker containers for the change to take effect. From your Terminal:
1
2

docker compose restart
docker compose up
  1. Next, create your custom configuration file, for example my-config.yml, and place it in the /data folder that you made available to Docker, above.

  1. Open your docker-compose.yml file again, this time to edit the nakama:entrypoint entry to add the --config flag pointing to your configuration file. It should look like this:

        /nakama/nakama --config /nakama/data/my-config.yml
