I am trying to set up ingress-nginx-controller with type as LoadBalancer using this guide for the configuration.
Couple of issues I'm observing -
issue#1) It does not create and deploy a ELB onto the AWS.
issue#2) The External-IP status is showing as pending for ever.

$ kubectl get services -n ingress-nginx  
NAME            TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)                      AGE   
ingress-nginx   LoadBalancer   10.108.245.210   <pending>     80:30742/TCP,443:31028/TCP   41m  

I've followed each step mentioned there

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/mandatory.yaml  
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/aws/service-l4.yaml  
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/aws/patch-configmap-l4.yaml  

here is the logs from the pod -

~$ kubectl get pods -n ingress-nginx
NAME                                        READY   STATUS    RESTARTS   AGE

The above error shows that service is not running properly. No event also showing up in describe service output-

I know there is a service specification tag externalIPs but expectation here is that once ELB instance is created, it will be auto populated -

spec:
  type: LoadBalancer
  externalIPs:
  - {{ ingress_lb_address or vip or masterIP }}

Please let me know if anything I'm missing here.
