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

Warning! Audit Deprecated

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.

Impact:

You require TLS to be configured on apiserver as well as 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.

Default Value:

By default, kubelet connections are over https.
