Change the ownership of the conf files to root: root by executing the command:

chown root:root /etc/kubernetes/admin.conf
chown root:root /etc/kubernetes/scheduler.conf
chown root:root /etc/kubernetes/controller-manager.conf

Check Contents

Review the Kubernetes conf files by using the command:

stat -c %U:%G /etc/kubernetes/admin.conf | grep -v root:root
stat -c %U:%G /etc/kubernetes/scheduler.conf | grep -v root:root
