Use MachineSet with VMware UPI setup

Warning

Work-in-progress and don't work! Tried with OCP 4.5

WTF: https://access.redhat.com/solutions/5086271

  • Create VMware template VM base on 4.5 OVA
  • Edit MachineSet
  • Update template (Add VM template name)

  • Update Network Config ( json path: .spec.template.spec.providerSpec.value.network.devices[0].networkName )

  • Problem in my env: VM start without hostname (localhost) - because dhcp do not send any hostname!

  • Add vSphere IPI Core set the hostname to the VM name in vSphere:
  • Those script and service only added if Infra.Status.PlatformStatus.VSphere.APIServerInternalIP is set!
  • "Work-a-round": Set the hostname via CLI: /usr/bin/hostnamectl --transient --static set-hostname XXX
  • Next problem: Nobody approved the CSR! If you approve via oc adm certificate approve, the node joins but the machineset didn't recognise.

  • Machine is still in provisioning. (oc get machine)

  • Problem machine does not have valid node reference -> https://bugzilla.redhat.com/show_bug.cgi?id=1834966
