⁠What is Core Keeper?

Explore an endless cavern of creatures, relics and resources in a mining sandbox adventure for 1-8 players. Mine, build, fight, craft and farm to unravel the mystery of the ancient Core.

⁠How to use this image

⁠Create volumes for persistent storage

docker volume create steamcmd_volume
docker volume create steam_app_volume
docker volume create corekeeper_save_volume

⁠Launch Core Keeper game server

docker run -d --net=host --name=core-keeper-dedicated \
    -v "steamcmd_volume:/home/steam/steamcmd" \
    -v "steam_app_volume:/home/steam/core-keeper-dedicated" \
    -v "corekeeper_save_volume:/home/steam/.config/unity3d/Pugstorm/Core Keeper" \
    xalimar/core-keeper-dedicated

⁠View the container logs to find the Game ID

You'll need this ID to join the game. You can press ctrl-c to stop watching the logfile

docker logs -f core-keeper-dedicated

⁠Copy an existing world to the server

Make sure to connect to the server for a few minutes so an initial 0.world.gzip save is created in the Docker volume. Then, stop the server container

docker stop core-keeper-dedicated

Locate your world file, for example it will be in a similar path to this. I highly recommend backing this up so you don't accidentally overwrite the wrong file.

C:\Users\<username>\AppData\LocalLow\Pugstorm\Core Keeper\Steam\<id>\worlds

It will be named 0.world.gzip. Copy that to the docker corekeeper_save_volume and overwrite the existing 0.world.gzip. With docker desktop on windows, you can find it here:

\\wsl$\docker-desktop-data\version-pack-data\community\docker\volumes\corekeeper_save_volume\_data\DedicatedServer\worlds

On Linux it will probably be located here:

/var/lib/docker/volumes/corekeeper_save_volume/_data/DedicatedServer/worlds

Finally, restart the container:

docker start core-keeper-dedicated
