Issues with ingress.yaml step

https://github.com/elmoallistair/qwiklabs/blob/d39d7d0f980f234e94999b8d02e7402270a8a34b/labs/gsp335_secure-workloads-in-google-kubernetes-engine-challenge-lab/guide.txt#L65

Have these steps been validated against the updated version of the challenge lab?  When I install the ingress controller, I am unable to access the WordPress site.
