Method: googleapis.compute.beta.regionInstanceGroupManagers.resize

Changes the intended size of the managed instance group. If you increase the size, the group creates new instances using the current instance template. If you decrease the size, the group deletes one or more instances. The resize operation is marked DONE if the resize request is successful. The underlying actions take additional time. You must separately verify the status of the creating or deleting actions with the listmanagedinstances method. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted.

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.

Arguments

Parameters
`instanceGroupManager`	`string` Required. Name of the managed instance group.
`project`	`string` Required. Project ID for this request.
`region`	`string` Required. Name of the region scoping this request.
`requestId`	`string` An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).
`size`	`integer (int32 format)` Number of instances that should exist in this instance group manager.

Raised exceptions

Exceptions
`ConnectionError`	In case of a network problem (such as DNS failure or refused connection).
`HttpError`	If the response status is >= 400 (excluding 429 and 503).
`TimeoutError`	If a long-running operation takes longer to finish than the specified timeout limit.
`TypeError`	If an operation or function receives an argument of the wrong type.
`ValueError`	If an operation or function receives an argument of the right type but an inappropriate value. For example, a negative timeout.
`OperationError`	If the long-running operation finished unsuccessfully.
`ResponseTypeError`	If the long-running operation returned a response of the wrong type.

Response

If successful, the response contains an instance of Operation.
