A simple Python script to create and run new Minecraft Server instances on the same server. It leverages Docker and finds a free port on the system to run it.
Just download multicraft.py to your favourite folder :)
- A Minecraft Docker container, e.g.: https://github.com/overshard/docker-minecraft (You'll have to hack multicraft.py a bit to adapt it to your container's name, which is "mcdocker" by default)
- Docker-py
- A Linux system to run all this
Just run it locally on a Linux system running Docker.
Example:
user@Server:~/repos/multicraft$ sudo ./multicraft.py
Instance ID: 9566729284dfc39cebd5f76a9987d8d86202190433cd4216fbc5c3ed140457dc
Listening on port 25565
user@Server:~/repos/multicraft$ sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9566729284df mcdocker "/start" 5 seconds ago Up 4 seconds 0.0.0.0:25565->25565/tcp sharp_bohr
user@Server:~/repos/multicraft$ sudo ./multicraft.py
Instance ID: a7212a66027096d462e8479bad20051f277ed65761ce4dfb95c0bd26adee5cec
Listening on port 25566
user@Server:~/repos/multicraft$ sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
a7212a660270 mcdocker "/start" 3 seconds ago Up 2 seconds 0.0.0.0:25566->25565/tcp goofy_turing
9566729284df mcdocker "/start" 18 seconds ago Up 17 seconds 0.0.0.0:25565->25565/tcp sharp_bohr
As you can see above, the second instance maps port 25566 on the host to 25565 on the Minecraft service inside the container. The /start script downloads the jar file for Minecraft server 1.8.8 and starts the server. The Docker image is Isaac Bythewood's docker-minecraft with minimal changes (namely Minecraft Server's version).
I've limited this to 3 simultaneous instances by default, but this limit is easily changeable inside the script.
