dry
Specifies whether to precheck the request. Valid values:
true: prechecks the request without creating an instance. The system prechecks the required parameters, request format, service limits, and available resources. If the request fails the precheck, the corresponding error message is returned. If the request passes the precheck, the DryRunOperation error code is returned.
false: checks the request. After the request passes the check, an instance is created.
