Information
Turn on Role Based Access Control.
Role Based Access Control (RBAC) allows fine-grained control over the operations that different entities can perform on different objects in the cluster. It is recommended to use the RBAC authorization mode.
Solution
Edit the API server pod specification file /etc/kubernetes/manifests/kube-apiserver.yaml on the Control Plane node and set the --authorization-mode parameter to a value that includes RBAC for example:
--authorization-mode=Node,RBAC
Impact:
When RBAC is enabled you will need to ensure that appropriate RBAC settings (including Roles, RoleBindings and ClusterRoleBindings) are configured to allow appropriate access.
