  • namespace

• spec

  Specification of the GracefulRebootRequest CR that contains the following fields:

  • machines

    List of machines for a rolling reboot. Each machine of the list is cordoned, drained, rebooted, and uncordoned in the order of cluster upgrade policy. For details about the upgrade order, see Change the upgrade order of a machine.

    Leave this field empty to reboot all cluster machines.
