1.1.4 Ensure that the --kubelet-https argument is set to true

Information

Use https for kubelet connections.

Rationale:

Connections from apiserver to kubelets could potentially carry sensitive data such as secrets and keys. It is thus important to use in-transit encryption for any communication between the apiserver and kubelets.

Solution

Edit the API server pod specification file '/etc/kubernetes/manifests/kube-apiserver.yaml' on the master node and remove the '--kubelet-https' parameter.
