 ## Enabling dynamic resource allocation

 kube-scheduler, kube-controller-manager and kubelet also need the feature gate.
 
 When a resource driver uses a control plane controller, then the
 `DRAControlPlaneController` feature gate has to be enabled in addition to
 `DynamicResourceAllocation`.
 
 A quick check whether a Kubernetes cluster supports the feature is to list
