InformationEnsure that the API server pod specification file has permissions of 600 or more restrictive.
The API server pod specification file controls various parameters that set the behavior of the API server. You should restrict its file permissions to maintain the integrity of the file. The file should be writable by only the administrators on the system.
SolutionRun the below command (based on the file location on your system) on the master node. For example,
chmod 600 /etc/kubernetes/manifests/kube-apiserver.yaml
By default, the kube-apiserver.yaml file has permissions of 640.
