(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. These upgrade settings configure the upgrade strategy for the node pool. Use 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 policy. The policy is used to control the way blue pool gets drained. The draining is executed in the batch mode. The batch size could be specified as either percentage of the node pool size or the number of nodes. batch_soak_duration is the soak time after each batch gets drained. 2. node_pool_soak_duration is the soak time after all blue nodes are drained. After this period, the blue pool nodes will be deleted. - `maxUnavailable` integer — The maximum number of nodes that can be simultaneously unavailable during the upgrade process.

Changing the locations for a node pool will result in nodes being either created or removed from the node pool, depending on whether locations are being added or removed. Warning: It is recommended to update node pool locations in a standalone API call. Do not combine a location update with changes to other fields (such as `tags`, `labels`, `taints`, etc.) in the same request. Otherwise, the API performs a structural modification where changes to other fields will only apply to newly created nodes and will not be applied to existing nodes in the node pool.

Allowed values are: * none: the default policy, and does not perform any topology alignment. * restricted: the topology manager stores the preferred NUMA node affinity for the container, and will reject the pod if the affinity if not preferred. * best-effort: the topology manager stores the preferred NUMA node affinity for the container. If the affinity is not preferred, the topology manager will admit the pod to the node anyway. * single-numa-node: the topology manager determines if the single NUMA node affinity is possible. If it is, Topology Manager will store this and the Hint Providers can then use this information when making the resource allocation decision. If, however, this is not possible then the Topology Manager will reject the pod from the node. This will result in a pod in a Terminated state with a pod admission failure. The default policy value is 'none' if unspecified.
