====== Minecraft Server ======

This show how to host a Minecraft Bedrock server.

[[https://github.com/itzg/docker-minecraft-bedrock-server?tab=readme-ov-file|This]] link refers to the docker solutuion choosen.

[[https://minecraft.wiki/w/Server.properties#Option_keys|This]] link details all the settings you can set as env variables in the composer.

===== Installation =====

See 
<code bash>
useradd -d /data/daemons/minecraft minecraft
mkdir /data/minecraft
chown minecraft:minecraft /data/minecraft/
</code>

<file - docker-compose.yaml>
services:
  bds:
    image: itzg/minecraft-bedrock-server
    environment:
      EULA: "TRUE"
    ports:
      - "19132:19132/udp"
    volumes:
      - ./data:/data
    stdin_open: true
    tty: true
</file>

<code bash>
podman compose pull
</code>


===== Remote Access =====

Mnecraft server doesn't use HTTP, so there is no need for a reverse proxy. You need to forward the UDP port from your external server to your internal (home) server (see [[networking:wireguard_redirects|here]]):

<code bash
# on external server!
nft add rule wg prerouting iifname "enp1s0" dnat ip to udp dport map { 19132 : 10.70.0.1 . 19132 }
/etc/init.d/nftables save
</code>


===== Autostart =====

Using my //user-containers// OpenRC script just link it:
<code bash>
cd /etc/init.d
ln -s user-containers user-containers.minecraft
</code>

Create /etc/conf.d/user-containers.minecraft:
<file - user-containers.minecraft>
USER=minecraft
DESCRIPTION="Minecraft Server"
</file>

And set it up for autostart:+
<code bash>
/etc/init.d/user-containers.minecraft start
rc-update add user-containers.minecraft default
</code>
