Over the last 10+ years, the use of SSL certificates to encrypt and verify the authenticity of traffic between a client and server has become ubiquitous. OpenShift is no exception. Certificates are used for communication between worker nodes and the control plane, between control plane nodes, and for many different components to communicate with each other. However, for most of us, the most obvious use of SSL certificates with OpenShift is when we connect to the API and ingress endpoints.

In this episode, we look into all the different ways SSL certificates are used in OpenShift, where they come from, how they’re lifecycled, how to replace the certificate authority, and other interesting aspects of the certificates used all across OpenShift.
