Set up the kubernetes integration.
Restrict kubelet nodes to reading only objects associated with them.
The Node authorization mode only allows kubelets to read Secret, ConfigMap, PersistentVolume, and PersistentVolumeClaim objects associated with their nodes.
Run the following command on the master node:
ps -ef | grep kube-apiserver
Verify that the
--authorization-mode argument exists and is set to a value to include Node.
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.
By default, Node authorization is not enabled.
