InformationEnsure that the controller manager pod specification file ownership is set to root:root.
The controller manager pod specification file controls various parameters that set the behavior of various components of the master node. You should set its file ownership to maintain the integrity of the file. The file should be owned by root:root.
SolutionRun the below command (based on the file location on your system) on the master node. For example,
chown root:root /etc/kubernetes/manifests/kube-controller-manager.yaml
By default, kube-controller-manager.yaml file ownership is set to root:root.
