Required. The location of the new cluster. For the required format, see the comment on the Cluster.name field.

Query parameters
Parameters
clusterId
string
Required. ID of the requesting object (the secondary cluster).
requestId
string
Optional. An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server ignores the request if it has already been completed. The server guarantees that for at least 60 minutes since the first request.
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 the original operation with the same request ID was received, and if so, ignores 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).
validateOnly
boolean
Optional. If set, performs request validation, for example, permission checks and any other type of validation, but does not actually execute the create request.
