Note that this is different from `kubectl drain --timeout`, which gives up and returns an error. On 2026-08-01, defaults to 0.

To get the actual value for your node group, please see 'strategy' in its status. Example: If set to 25%, the node group can scale up by an additional 25% during the update, allowing new nodes to be added before old nodes are removed, which helps minimize workload disruption. NOTE: it is user responsibility to ensure that there are enough quota for provision nodes above the desired number. Available quota effectively limits `max_surge`.
