#Enable DRA(Dynamic Resource Allocation) and corresponding API groups in Kubernetes

DRA support is enabled by default in Kubernetes 1.34 and later. Earlier versions, starting from 1.32, support for this feature requires manual activation.

#Steps to Enable DRA in Kubernetes 1.32–1.33

On the all master nodes:

1. Edit kube-apiserver component manifests in /etc/kubernetes/manifests/kube-apiserver.yaml:

   spec:
     containers:
     - command:
       - kube-apiserver
       - --feature-gates=DynamicResourceAllocation=true # required
       - --runtime-config=resource.k8s.io/v1beta1 # required
       - --runtime-config=resource.k8s.io/v1beta2 # required
       # ... other flags

2. Edit kube-controller-manager component manifests in /etc/kubernetes/manifests/kube-controller-manager.yaml:

   spec:
     containers:
     - command:
       - kube-controller-manager
       - --feature-gates=DynamicResourceAllocation=true # required
       # ... other flags

3. Edit kube-scheduler component manifests in /etc/kubernetes/manifests/kube-scheduler.yaml:

   spec:
     containers:
     - command:
       - kube-scheduler
       - --feature-gates=DynamicResourceAllocation=true
       # ... other flags

4. For kubelet, edit /var/lib/kubelet/config.yaml on the all nodes:

   apiVersion: kubelet.config.k8s.io/v1beta1
   kind: KubeletConfiguration
   featureGates:
     DynamicResourceAllocation: true

   Restart kubelet:

   sudo systemctl restart kubelet
