Information

Ensure that the scheduler pod specification file has permissions of 644 or more restrictive.

Rationale:

The scheduler pod specification file controls various parameters that set the behavior of the Scheduler service in the master node. 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.

Impact:

None

Solution

Run the below command (based on the file location on your system) on the master node. For example,

chmod 644 /etc/kubernetes/manifests/kube-scheduler.yaml

Default Value:

By default, kube-scheduler.yaml file has permissions of 640.
