regionInstanceGroupManagers

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 theresize request is successful. The underlying actions take additional time. You must separately verify the status of thecreating or deleting actions 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.

Path parameters

projectstring required

Project ID for this request.

regionstring required

Name of the region scoping this request.

instanceGroupManagerstring required

Name of the managed instance group.

Query parameters

sizeinteger required

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

requestIdstring

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).
