Kubernetes Ingress not resolving backend service

Question

I've created an ingress and pointed it to service type NodePort, But when i describe the ingress, the backend IP sjows <none>.

This is my deployment yaml

apiVersion: v1
kind: Namespace
metadata:
  name: proxy
  labels:
   name: proxy
---
apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: deployment
  namespace: proxy
  labels:
    app: proxy
spec:
  replicas: 1
  template:

        app: proxy
    spec:
      containers:
      - name: proxy
        image: wildapplications/proxy:latest
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 8080
      imagePullSecrets:
        - name: regsecret

apiVersion: v1
kind: Service
metadata:
  name: service
  namespace: proxy
spec:
  type: NodePort
  ports:
  - port: 8080
    targetPort: 8080
  selector:
    app: proxy
  externalName: proxy
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress
  namespace: proxy
  annotations:
    ingress.kubernetes.io/rewrite-target: /
spec:

    http:
      paths:
      - path: /test
        backend:
          serviceName: service
          servicePort: 8080

when I describe the ingress I get

Name:             ingress
Namespace:        proxy

I think you're trying to access the ingress through my minikube ip address (minikube ip to get the ip), this will probable provide a 404

To solve the 404, execute

echo "$(minikube ip) echo.example.com" | sudo tee -a /etc/hosts

and then from there navigating to the host url in my browser.
