I've ran a Minecraft server at home since December 2017 for me and my son to play on. We start a brand new one somewhere between every day and every week. The older he gets the longer the server lasts.
In all these years, I've been popping open the command line and running the server manually, and even inside of Digital Ocean occasionally to play a more public server with a friend.
My buddy Nic has been sharing me some of his homelab setup, and it's really got me to thinking about what I can run at home, and Dockerizing all the things. Today I found a really sweet github repo that had a minecraft server running in docker with a pretty incredible setup.
I ended up running the first thing in the Readme that included a volume mount. If you are going to run this container, I HIGHLY reccomend that you make sure that you have your world volume mounted, otherwise it will die with your docker container.
Docker Compose
With the following stored as my docker-compose.yml in a brand new and otherwise empty directory I was ready to start the server for the night.
version: "3"
services:
mc:
container_name: walkercraft
image: itzg/minecraft-server
ports:
- 25565:25565
environment:
EULA: "TRUE"
tty: true
stdin_open: true
restart: unless-stopped
volumes:
# attach a directory relative to the directory containing this compose file
- ./minecraft-data:/data
To start the server we open up the terminal in this directory and run the follwing command.
docker compose up -d
Once its up and running we can run commands on the server simply by attaching to it.
docker attach walkercraft
A few common commands we run in the server
We play very casually most of the time so we will set keepInventory to true so that we do not loose our inventory when we die. Sometimes we also op ourselve so that we can toggle gamemode into creative.
# set the game to keep your inventory when you die.
/gamrule keepInventory true
# give everyone operater priveledges to they can run commands
/op @a
# give playername op
/op playername
