deleteInstances method

Future<Operation> deleteInstances(InstanceGroupManagersDeleteInstancesRequest request, String project, String zone, String instanceGroupManager, { String? requestId, String? $fields, })

Flags the specified instances in the managed instance group for immediate deletion.

The instances are also removed from any target pools of which they were a member. This method reduces thetargetSize of the managed instance group by the number of instances that you delete. This operation is marked as DONE when the action is scheduled even if the instances are still being deleted. You must separately verify the status of the deleting action with thelistmanagedinstances 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.

You can specify a maximum of 1000 instances with this method per request.

request - The metadata request object.

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}\[a-z0-9\])?)).

zone - The name of thezone where the managed instance group is located.

instanceGroupManager - The name of the managed instance group.

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.
