Docker deployment

A multi-stage image bundles Cube with a JRE, so a container can launch Minecraft servers out of the box.

Docker Compose

The repository ships a docker-compose.yml. From the project root:

docker compose up -d --build

This builds the image, starts Cube, and persists everything to a named volume mounted at /data. Open http://localhost:8080 and check the container logs for the first-run admin link:

docker compose logs cube

Plain Docker

docker build -t cube .
docker run -d --name cube \
  -p 8080:8080 -p 25565:25565 \
  -v cube-data:/data \
  cube

Ports

• 8080 — the Cube web UI.
• 25565 — the default Minecraft port. Each server listens on the port in its server.properties; map an additional host port for every extra server you run.

Data & persistence

All state — the SQLite database and every server's working directory — lives under /data. Keep that on a volume (as the compose file does) so it survives container recreation.
