Security

This container runs Java as a non-privileged user, with uid=567 and gid=567 by default (see USER_UID and USER_GID environment variables), meaning that local volumes need to set permissions accordingly.

Example command

# Create volumes and set permissions
mkdir data
chown -R 567:567 data

# Run the server
docker run -d \
  --name stoneblock3 \
  --restart unless-stopped \
  -p 25565:25565 \
  -e MODPACK_ID=100 \
  -e EULA=true \
  -v $(pwd)/data:/server \
