1.1.28 Ensure that the --tls-cert-file and --tls-private-key-file arguments are set as appropriate - tls-private-key-file

Information

Setup TLS connection on the API server.

Rationale:

API server communication contains sensitive parameters that should remain encrypted in transit. Configure the API server to serve only HTTPS traffic.

Solution

Follow the Kubernetes documentation and set up the TLS connection on the apiserver. Then, edit the API server pod specification file '/etc/kubernetes/manifests/kube-apiserver.yaml' on the master node and set the TLS certificate and private key file parameters.

--tls-cert-file=
--tls-private-key-file=

Impact:

TLS and client certificate authentication must be configured for your Kubernetes cluster deployment.
