Method: googleapis.container.v1.projects.zones.clusters.nodePools.rollback

Rolls back a previously Aborted or Failed NodePool upgrade. This makes no changes if the last upgrade successfully completed.

This method waits—the workflow execution is paused—until the operation is complete, fails, or times out. The default timeout value is 1800 seconds (30 minutes) and can be changed to a maximum value of 31536000 seconds (one year) for long-running operations using the connector_params field. See the Connectors reference.

The connector uses polling to monitor the long-running operation, which might generate additional billable steps. For more information about retries and long-running operations, refer to Understand connectors.

The polling policy for the long-running operation can be configured. To set the connector-specific parameters (connector_params), refer to Invoke a connector call.
