manymine

A simple way to run multiple Minecraft Bedrock servers in docker containers on the same host, and be able to discover them as LAN games.

Run your Minecraft Bedrock servers on non-default ports (e.g. 60601, 60602...)

Add the label 'manymine.enable=true' to each server container you want manymine to announce to clients.

Both manymine and your minecraft servers need to be on the same docker network.

Docker Compose

Using docker compose, you'll want something like this:

version: "3.7"
services:
  manymine:
    image: illiteratealliterator/manymine
    container_name: manymine
    ports:
      - '19132:19132/udp'
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

  minecraft-a:
    image: itzg/minecraft-bedrock-server
    container_name: minecraft-a
    environment:
      - EULA=TRUE
      - SERVER_NAME=Server A
      - SERVER_PORT=60601
    volumes:
      - minecraft-a-data:/data
    ports:
      - '60601:60601/udp'
    labels:
      - manymine.enable=true

  minecraft-b:
    image: itzg/minecraft-bedrock-server
    container_name: minecraft-b
    environment:
      - EULA=TRUE
      - SERVER_NAME=Server B
      - SERVER_PORT=60602
    volumes:
      - minecraft-b-data:/data
    ports:
      - '60602:60602/udp'
    labels:
      - manymine.enable=true

volumes:
  minecraft-a-data:
  minecraft-b-data:
