Required. The name of the parent resource. For the required format, see the comment on the Instance.name field.
Authorization requires the following IAM permission on the specified resource parent:
alloydb.instances.create
Query parameters
Parameters
instanceId
string
Required. ID of the requesting object.
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.
Request body
The request body contains an instance of Instance.
Response body
If successful, the response body contains an instance of Operation.
