  • allow firewall to see UPnP devices
  • use hostNetwork: true (Workaround, preferable LoadBalancer)

Problem with the OpenHAB time!

This seems to solve it:

    env:
    - name: "TZ"
      value: "Europe/Berlin"

    volumeMounts:
    - name: etc-localtime
      mountPath: /etc/localtime
    - name: etc-timezone
      mountPath: /etc/timezone

  volumes:
  - name: etc-localtime
    hostPath:
      path: /usr/share/zoneinfo/Europe/Berlin
  - name: etc-timezone
    hostPath:
      path: /usr/share/zoneinfo/Europe/Berlin

→ Settings/Regional Settings → no TimeZone (The underlying system’s time zone is the default.)

how would you access the items files etc. I am using Longhorn for persistent storage. I guess I need to add a samba container to the pod?
