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

HighLevel 1Manual reviewopenshift

Description

Setup TLS connection on the Kubelets. The benchmark marks this recommendation Manual.

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

By default, OpenShift uses X.509 certificates to provide secure connections between the API server and node/kubelet. OpenShift Container Platform monitors certificates for proper validity, for the cluster certificates it issues and manages. The OpenShift Container Platform manages certificate rotation and the alerting framework has rules to help identify when a certificate issue is about to occur.

How it is fixed

Fix method: Guidance or infrastructure patch

OpenShift automatically manages TLS authentication for the API server communication with the node/kublet. This is not configurable.
