Can't get haproxy-ingress to work

I have been trying to get an HAProxy Ingress working on my kubernetes cluster. I have been following the instructions in the README (https://github.com/jcmoraisjr/haproxy-ingress/tree/master/examples/deployment). I see that haproxy-ingress pod has this in its log:

I0617 16:50:31.298997       6 launch.go:181]

The one thing to note that didn't seem to work in the README was this:

kubectl --namespace=ingress-controller create -f haproxy-ingress.yaml

That command failed with this error:

error: unable to recognize "haproxy-ingress.yaml": no matches for kind "Deployment" in version "apps/v1beta2"

I had to change the apiVersion: apps/v1beta2 to apiVersion: apps/v1

Did that cause the problem?

Thanks!

Upate:

I was able to get the haproxy-ingress pod to finally launch without error. After much trial and error I final figured out that I need to update the haproxy-ingress "deployment" (via the dashbaord). I only had to add the one line:

serviceAccountName: ingress-controller

directly after the spec: tag.

I am still not able to get an external address.

when I run

kubectl describe ingress app --namespace=ingress-controller

I do not see an IP address associated with host.

$ kubectl describe ingress app --namespace=ingress-controller
Name:             app
Namespace:        ingress-controller
Address:
Default backend:  default-http-backend:80 (<error: endpoints "default-http-backend" not found>)

  Normal  UPDATE  18m (x3 over 10h)  ingress-controller  Ingress ingress-controller/app
  Normal  UPDATE  18m (x2 over 19m)  ingress-controller  Ingress ingress-controller/app

and if I execute

$ kubectl get service -A -o wide

I see that no service has an external ip.

Update II

Turns out I don't need to see external ips.
