public Optional<String> controller() {
        return Optional.ofNullable(this.controller);
    }
@return Controller is the name of the DRA driver that is meant to handle allocation of this claim. If empty, allocation is handled by the scheduler while scheduling a pod.

Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver.

This is an alpha field and requires enabling the DRAControlPlaneController feature gate.
