Minecraft Server Setup

Before You Begin

• Install Docker Desktop if you don’t already have it.
• Decide if your server will be local only or public with a domain.
• A domain makes connecting easier. Providers like Porkbun sell domains for $1–10/year.

Part 1: Base Server Setup

1. Get the files: Download the preferred version from Releases and then extract the files to your preferred storage location.
2. Accept the EULA:
   • Navigate to ./minecraft-docker/server/
   • Open eula.txt
   • Change eula=false → eula=true
3. Configure the server: Edit server.properties. By default, whitelist is enabled (recommended).
4. Choose server version: Replace server.jar in ./minecraft-docker/build/ to use another version (e.g., Paper).
5. Adjust memory (optional):
   • Edit ./minecraft-docker/Dockerfile
   • Key arguments:
     • -Xms2G → Minimum RAM
     • -Xmx8G → Maximum RAM
6. Start the server:

   docker compose up

7. Whitelist players:

   docker attach minecraft
   whitelist add <minecraft_username>

8. Test locally: Launch Minecraft and connect to localhost.

Part 2: Domain + Port Forwarding (Optional)

1. Find your public IP: Visit whatsmyip.com.
2. Set up DNS:
   • Create an A record (e.g., play.yourdomain.com)
   • Point it to your public IP
   • Use port 25565
3. Allow firewall traffic (Windows):
   • Open Windows Defender Firewall
   • Create a new Inbound Rule for TCP port 25565
4. Port forward on your router: Forward TCP 25565 to your server’s local IP.
5. Test external access:
   • Other computers connect with play.yourdomain.com
   • Host machine connects with localhost
