resize method

Future<Operation> resize(
  1. String project,
  2. String region,
  3. String instanceGroupManager,
  4. int size, {
  5. String? requestId,
  6. String? $fields,
})

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.

Request parameters:

project - Project ID for this request. Value must have pattern (?:(?:\[-a-z0-9\]{1,63}\.)*(?:\[a-z\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?):)?(?:\[0-9\]{1,19}|(?:\[a-z0-9\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?)).

region - Name of the region scoping this request.

instanceGroupManager - Name of the managed instance group.

size - Number of instances that should exist in this instance group manager.

requestId - 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).

$fields - Selector specifying which fields to include in a partial response.

Completes with a Operation.

Completes with a commons.ApiRequestError if the API endpoint returned an error.

If the used http.Client completes with an error when making a REST call, this method will complete with the same error.
