Kubernetes on vSphere 101 – Ingress

As I was researching content for the 101 series, I came across the concept of an Ingress. As I hadn’t come across it before, I wanted to do a little more research on what it actually did.

But they are significantly different in how they do this. If we take the Load Balancer service type first, then for every service that is exposed via a Load Balancer, a unique external…
