Create two directories where you want to run your server :
server-data: mandatory if you want to keep configuration between each restartserver-files: optional, contains all the files of the application
docker run -d -e WORLD_NAME="Core Keeper Server" -e MAX_PLAYERS=5 -v $(pwd)/server-data:/home/steam/core-keeper-data --name core-keeper-dedicated escaping/core-keeper-dedicated
Create a docker-compose.yml with the following content:
version: "3"
services:
core-keeper:
image: escaping/core-keeper-dedicated
volumes:
- server-files:/home/steam/core-keeper-dedicated
- server-data:/home/steam/core-keeper-data
env_file:
- ./core.env
restart: always
stop_grace_period: 2m
volumes:
server-files:
server-data:
Create a core.env file, it should contain the environment variables for the dedicated server, see configuration for reference. Example:
WORLD_INDEX=0
WORLD_NAME=Core Keeper Server
WORLD_SEED=0
GAME_ID=
DATA_PATH=
MAX_PLAYERS=10
DISCORD=1
DISCORD_HOOK=https://discord.com/api/webhooks/{id}/{token}
On the folder which contains the files run docker-compose up -d.
A GameID.txt file will be created next to the executable containing the Game ID. If it doesn't appear you can check the log in the same location named core-keeper-dedicated/CoreKeeperServerLog.txt for errors.
To query the game ID run:
docker exec -it core-keeper-dedicated cat core-keeper-dedicated/GameID.txt
These are the arguments you can use to customize server behavior with default values.
WORLD_INDEX Which world index to use.
WORLD_NAME The name to use for the server.
WORLD_SEED The seed to use for a new world. Set to 0 to generate random seed.
