Shameless plug! The insights in this article are pretty deep but if you're looking for just a clumsy step 1 to setting up the NGINX ingress controller on Kubernetes, check out what I wrote:
The most important thing that I found out while working on the NGINX controller was that you can just jump into it and do some debugging by poking around at the NGINX configuration that's inside it. There's no insight in there as deep as what's in this article, but for those that are maybe new to Kubernetes, hope it's helpful!
