Minecraft is a game about placing blocks and going on adventures.


This chart creates a single Minecraft Pod, plus Services for the Minecraft server and RCON.


  • 512 MB of RAM
  • Kubernetes 1.4+ with Beta APIs enabled
  • PV provisioner support in the underlying infrastructure

Installing the Chart

To install the chart with the release name my-release, read the Minecraft EULA run:

$ helm install –name my-release –set minecraftServer.eula=true stable/minecraft

This command deploys a Minecraft dedicated server with sensible defaults.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.


Refer to values.yaml for the full run-down on defaults. These are a mixture of Kubernetes and Minecraft-related directives that map to environment variables in the itzg/minecraft-server Docker image.

Specify each parameter using the –set key=value[,key=value] argument to helm install. For example,

$ helm install –name my-release \
–set minecraftServer.eula=true,minecraftServer.Difficulty=hard \

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

$ helm install –name my-release -f values.yaml stable/minecraft

Tip: You can use the default values.yaml


The itzg/minecraft-server image stores the saved games and mods under /data.

By default a PersistentVolumeClaim is created and mounted for saves but not mods. In order to disable this functionality you can change the values.yaml to disable persistence under the sub-sections under persistence.

“An emptyDir volume is first created when a Pod is assigned to a Node, and exists as long as that Pod is running on that node. When a Pod is removed from a node for any reason, the data in the emptyDir is deleted forever.”
