Method: regionCommitments.updateReservations

Transfers GPUs or local SSDs between reservations within commitments.

HTTP request

POST https://compute.googleapis.com/compute/beta/projects/{project}/regions/{region}/commitments/{commitment}/updateReservations

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.
region

string

Name of the region for this request.
commitment

string

Name of the commitment for which the reservation is being updated.

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).

Response body

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 zoneOperations resource.

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

Note that completed Operation resources have a limited retention period.

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

string

The reason of the error. This is a constant value that identifies the proximate cause of the error. Error reasons are unique within a particular domain of errors. This should be at most 63 characters and match a regular expression of [A-Z][A-Z0-9_]+[A-Z0-9], which represents UPPER_SNAKE_CASE.
error.errors[].errorDetails[].errorInfo.domain

string

The logical grouping to which the "reason" belongs. The error domain is typically the registered service name of the tool or product that generates the error. Example: "pubsub.googleapis.com".
