Quickly Set Up a Minecraft Server on macOS + Docker

Setting Up a Minecraft Server is a Hassle

It’s nostalgic to think about the days of doing all sorts of things like Forge and Java. Fortunately, now you can run a Minecraft server, backups, and other features with just docker compose up. I think this is good enough for quickly setting up a server.

Install Orbstack

This phrase might sound unfamiliar, but just think of it as Docker.

OrbStack · Fast, light, simple Docker & Linux

Say goodbye to slow, clunky containers and VMs. The fast, light, and easy way to run containers and Linux. Develop at lightspeed with our Docker Desktop alternative.

orbstack.dev

You can consider this a replacement for Docker Desktop that works on macOS.

Create a Docker Compose

We will create a Docker compose file.

Sample Images Used in YAML

This is just one example, so you can add various things to this or perhaps you only need the server part.

itzg/minecraft-server:latest

• The Minecraft server runs completely on this one image. https://docker-minecraft-server.readthedocs.io/en/latest/#using-docker-compose

itzg/mc-backup

• This image creates backups at regular intervals. There is a unique communication form called RCON (Remote Console) used by Minecraft, which saves the world automatically.
