This is a bit of a mixed video. I go into some detail about cert-manager, we look at the default ingressclass in OpenShift with some exploration of the code behind it.

We also shutdown the k8s cluster and migrate VM's from our OpenStack compute node into Fedora Server.

Links to the ingress class code:
This controller is responsible for the translation of Ingress resources into Route resources:

It looks for TLS Secrets that are being used by the Ingress definition, and ensures they are added to the route:
