Method: instanceGroupManagers.setTargetPools

Modifies the target pools to which all instances in this managed instance group are assigned. The target pools automatically apply to all of the instances in the managed instance group. This operation is marked DONE when you make the request even if the instances have not yet been added to their target pools. The change might take some time to apply to all of the instances in the group depending on the size of the group.

HTTP request

POST https://compute.googleapis.com/compute/v1/projects/{project}/zones/{zone}/instanceGroupManagers/{resourceId}/setTargetPools

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.

zone

string

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

resourceId

string

The name of the managed instance group.

Authorization requires the following IAM permission on the specified resource instanceGroupManager:

  • compute.instanceGroupManagers.update

Query parameters

Parameters
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).

Request body

The request body contains data with the following structure:

JSON representation
{
  "targetPools": [
    string
  ],
  "fingerprint": string
}
Fields
targetPools[]

string

The list of target pool URLs that instances in this managed instance group belong to. The managed instance group applies these target pools to all of the instances in the group. Existing instances and new instances in the group all receive these target pool settings.

Authorization requires the following IAM permission on the specified resource targetPools:

  • compute.targetPools.get
fingerprint

string (bytes format)

The fingerprint of the target pools information. Use this optional property to prevent conflicts when multiple users change the target pools settings concurrently. Obtain the fingerprint with the instanceGroupManagers.get method. Then, include the fingerprint in your request to ensure that you do not overwrite changes that were applied from another concurrent request.

A base64-encoded string.

Response body

If successful, the response body contains data with the following structure:

Represents an Operation resource.

Google Compute Engine has three Operation resources:

You can use an operation resource to manage asynchronous API requests. For more information, read Handling API responses.

Operations can be global, regional or zonal.

  • For global operations, use the globalOperations resource.
  • For regional operations, use the regionOperations resource.
  • For zonal operations, use the zonalOperations resource.

For more information, read Global, Regional, and Zonal Resources.
