Install Minecraft

In this lab we are going to install and configure Minecraft with the option to load custom worlds/maps.

Prerequisites:

We are assuming you are running the Equivalent to the SUSE at Home Base which includes the following:

 * Rancher 2.5+ or 2.6+
 * Kubernetes Cluster (k3s)
    LoadBalancer - Metallb

  * Persistent Storage 
     Storage Class defined and set as Default Storage Class

What Version do I want to install?

There are 2 versions of the Minecraft server, Java and Bedrock

Java is the original version and has the most mods, skins and worlds but it only supports Computer based (Java) clients (No consoles). It also has a large variety of options you can tweak (I,E, Hardcore Survival mode) when you launch the server.

Bedrock is was written by Microsoft in 2017 from the ground up. It supports modern console (unlike the Java version). It currently has less mods and worlds but this is quickly changing. It has less options to customize your World on Launch
