Docker containers for Minecraft
I set these up to make it easier to build gnembon's CarpetMod. The Dockerfile for vanilla Minecraft is based on PHLAK's docker-minecraft project, with some improvements (such as server jar URL lookup from human-readable version id).
I won't link to the repositories of the prebuilt images because (as I understand
it) distributing Docker images with the Minecraft jar bundled in to them is
against the EULA, but I've included cloudbuild.yaml files so that you can build
them with Google Cloud Build if you wish (or see how one might run docker build locally).
Also, at some point Mojang changed the server jar downloads from
mojang.com/HUMAN_READABLE_VERSION-server.jar to
mojang.com/UNREADABLE_BLOB_ID-server.jar, so I created a script to automate
the translations (versions are sourced from
mcversions.net).
Running the server
The only one-time setup you need to do is create a docker volume to store the world data:
docker volume create --name minecraft-data
To run the Minecraft server:
GCP_PROJECT_ID=your-project-id
MC_VERSION=1.12.2
SERVER_TYPE=vanilla # or carpet
docker run -it -d -p 25565:25565 -v minecraft-data:/etc/minecraft --name minecraft-server gcr.io/${GCP_PROJECT_ID}/minecraft-${SERVER_TYPE}:${MC_VERSION}
