A production-oriented Docker image for running a Minecraft Java server as a non-root user, with the server JAR downloaded at container startup.

• Runs as a dedicated non-root user.
• Downloads server.jar from JAR_URL at startup with retry support.
• Supports optional checksum verification via JAR_SHA256.
• Stores all mutable server state under /data.
• Includes hardened example run scripts for both Java server and proxy workflows.

docker pull ghcr.io/hauntedmc/mcserver:latest

cp examples/run-minecraft-server.sh ./run-mcserver.sh
chmod +x ./run-mcserver.sh
# Edit JAR_URL and other config values first
./run-mcserver.sh

For proxy deployments (for example Velocity), use examples/run-proxy-server.sh. That script sets MC_NOGUI=false because Velocity does not accept the --nogui startup argument. For internal-only Docker network deployments, set ENABLE_JAVA_PORT="false" in either example script.

docker run \
 --name minecraft-server \
 --restart unless-stopped \
 -d \
 -p 25565:25565/tcp \
 -p 25565:25565/udp \
 -e JVM_MEMORY=8G \
 -e JAR_URL='https://example.com/path/to/server.jar' \
 -v "$PWD/data:/data" \
 ghcr.io/hauntedmc/mcserver:latest

To keep the server internal-only on Docker network, omit the -p flags.
