Information

Restrict kubelet nodes to reading only objects associated with them.

Rationale:

The Node authorization mode only allows kubelets to read Secret, ConfigMap, PersistentVolume, and PersistentVolumeClaim objects associated with their nodes.

Impact:

None

Solution

Edit the API server pod specification file /etc/kubernetes/manifests/kube-apiserver.yaml on the master node and set the --authorization-mode parameter to a value that includes Node.

--authorization-mode=Node,RBAC

Default Value:

By default, Node authorization is not enabled.
