Anthos Multi-Cloud V1 API - Class Google::Cloud::GkeMultiCloud::V1::UpdateSettings (v0.15.0)

Reference documentation and code samples for the Anthos Multi-Cloud V1 API class Google::Cloud::GkeMultiCloud::V1::UpdateSettings.

UpdateSettings control the level of parallelism and the level of disruption caused during the update of a node pool.

These settings are applicable when the node pool update requires replacing the existing node pool nodes with the updated ones.

UpdateSettings are optional. When UpdateSettings are not specified during the node pool creation, a default is chosen based on the parent cluster's version. For clusters with minor version 1.27 and later, a default surge_settings configuration with max_surge = 1 and max_unavailable = 0 is used. For clusters with older versions, node pool updates use the traditional rolling update mechanism of updating one node at a time in a "terminate before create" fashion and update_settings is not applicable.

Set the surge_settings parameter to use the Surge Update mechanism for the rolling update of node pool nodes.

1. max_surge controls the number of additional nodes that can be created beyond the current size of the node pool temporarily for the time of the update to increase the number of available nodes.
2. max_unavailable controls the number of nodes that can be simultaneously unavailable during the update.
3. (max_surge + max_unavailable) determines the level of parallelism (i.e., the number of nodes being updated at the same time).
