I have setup Nginx Controller as mentioned in the docs https://docs.nginx.com/nginx-ingress-controller/installation/installation-with-manifests/. I have setup the Ingress with the below configuration

IngressClass

apiVersion: networking.k8s.io/v1beta1
kind: IngressClass
metadata:
  name: nginx
  # annotations:
  #   ingressclass.kubernetes.io/is-default-class: "true"
spec:
  controller: nginx.org/ingress-controller

Ingress

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: hn-service-ingress
spec:
  ingressClassName: nginx
  rules:
  - host: hostnameservice.classpath.com
    http:
      paths:
      - path: /test
        backend:
          serviceName: hostname-service
          servicePort: 80

Below is the error when running the describe command. I am getting All hosts are taken by other resources

When I used to check with the cafe example, it is working fine. Where am I going wrong?

Note: I have configured the AWS load balancer and set the /etc/hosts to point to the ELB from AWS using the dnslookup.
