  # To enable the PodDisruptionBudget, configure it by specifying the
  # `minAvailable` or `maxUnavailable`. For example, to set the
  # minimum number of available replicas to 1, you can update this value as follows:
  #
  # podDisruptionBudget:
  #   minAvailable: 1
  #
  # Or, to allow a maximum of 1 unavailable replica, you can set:
  #
  # podDisruptionBudget:
