      # These upgrade settings control the level of parallelism and the level of

      # that can be simultaneously unavailable. maxSurge controls the number of
      # additional nodes that can be added to the node pool temporarily for the time
      # of the upgrade to increase the number of available nodes. (maxUnavailable +
      # maxSurge) determines the level of parallelism (how many nodes are being
      # upgraded at the same time). Note: upgrades inevitably introduce some
      # disruption since workloads need to be moved from old nodes to new, upgraded
      # ones. Even if maxUnavailable=0, this holds true. (Disruption stays within the
      # limits of PodDisruptionBudget, if it is configured.) Consider a hypothetical
      # node pool with 5 nodes having maxSurge=2, maxUnavailable=1. This means the
      # upgrade process upgrades 3 nodes simultaneously. It creates 2 additional (
      # upgraded) nodes, then it brings down 3 old (not yet upgraded) nodes at the
      # same time. This ensures that there are always at least 4 nodes available.

      # strategy to switch between the strategies applied to the node pool. If the
      # strategy is ROLLING, use max_surge and max_unavailable to control the level of
      # parallelism and the level of disruption caused by upgrade. 1. maxSurge
      # controls the number of additional nodes that can be added to the node pool
      # temporarily for the time of the upgrade to increase the number of available
      # nodes. 2. maxUnavailable controls the number of nodes that can be
      # simultaneously unavailable. 3. (maxUnavailable + maxSurge) determines the
      # level of parallelism (how many nodes are being upgraded at the same time). If
      # the strategy is BLUE_GREEN, use blue_green_settings to configure the blue-
      # green upgrade related settings. 1. standard_rollout_policy is the default
