ungleich-hardware

This container is made for configuring hardware on our clusters. It usually needs to run in privileged mode.

The source repository for this container is on code.ungleich.ch. This image uses significant content from the hwraid page that we would like to thank for its years long contribution.

See also the ungleich hardware maintenance guide, which describes the use of various hardware raid tools.

To enable access to devices and give permission to the pod to use it, you could use:

apiVersion: v1
kind: Pod
metadata:
  name: ungleich-hardware
spec:
  containers:
  - name: ungleich-hardware
    image: harbor.ungleich.svc.p10.k8s.ooo/ungleich-public/ungleich-hardware:0.0.1
    args:
    - sleep
    - "1000000"
    volumeMounts:
      - mountPath: /dev
        name: dev
    securityContext:
      privileged: true
  volumes:
    - name: dev
      hostPath:
        path: /dev

You might want to schedule the pod on a specific system, which you can use using the nodeSelector:

...
  nodeSelector:
    kubernetes.io/hostname: "server49"
....
