Minecraft is available through the custom helm chart (including a server downloader). The example below installs nimcraft. For each installation you'll want to create your own values.yaml with a new port. The server-downloader is called "minecraft_get_server" and is available on Github.

Testing

helm upgrade --install \
    testcraft \
    ./kubernetes/graduated/minecraft \
    --namespace minecraft \

Nimcraft
