Rob_Michel As BrianEhlert mentioned, you need to change your annotation and Ingress resource slightly to match the commercial version of NGINX Ingress controller.

You can try something like this:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: cafe-ingress
  annotations:
    nginx.org/rewrites: "serviceName=httpbin-service rewrite=/"
spec:
  rules:
  - host: cat.abitofhelp.io
    http:
      paths:
      - path: /httpbin/
        pathType: Prefix
        backend:
          service:
            name: httpbin-service
            port:
              number: 8999

Make sure you adjust accordingly to match your environment.

Hi Guys,

Thank you very much for your detailed responses!  I am traveling today but will make the changes when I get to the office and will report back.   If things go well, I will put together a simple demo that implements current best practices for gateway security and routes gRPC and HTTP->HTTPS traffic.  I will use it for a presentation to Management and will post it here and in a few other locations to help others kick-start a demo.

We are currently using Emissary Ingress and are tired of wrangling poor documentation, bugs, and lack of quality community/support.  My hope is to get the green light to migrate to nginx.com.

I will report back and want to thank you for your help!

Mike
