Docker Image packaging for Minecraft. This image uses the official slim Java Buster image as a base and sets up an entrypoint and volumes for running a Minecraft server. It also automatically agrees to the EULA. If you mount a folder to /opt/mcserver that contains an mcserver.jar then it'll be run by default with some sensible JVM arguments. This image is available on the Docker Hub.
Make sure to set a memory limit on your container, and this image will obey this memory limit for overall memory usage. By default, we set a 50/50 split for heap size and everything else.
JVM_INIT_RAM_PERCENT: Initial memory allocated for the heap at startup (default: 50)JVM_MAX_RAM_PERCENT: Maximum memory allocated for the heap (default: 50)
