@ppawlowski can you have quick look at this and see if you can suggest anything else (it needs cleaning up before publishing, but I wanted to check a place holder in)

Installing ingress controller will create a Load Balancer. In Azure, Load Balanacer does not support TLS termination. This should be handled by the ingress object definition manually or automatically via cert-manager.

The TLS/HTTPS support may need a helm chart (and driver-k8s) update to work properly.
