Expose the echo and httpbin services outside the Kubernetes cluster by defining Ingress rules.

#### Add ingress resource for echo service
Add an Ingress resource which proxies requests to  /foo to the httpbin service and /bar to the echo service

**NOTE** This is the new syntax for Kubernetes version 1.22 onwards

```bash
echo '
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: demo
  annotations:
    konghq.com/strip-path: "true"
    kubernetes.io/ingress.class: kong
spec:
  rules:
  - http:
      paths:
      - path: /foo
        pathType: Prefix
        backend:
          service:
            name: httpbin
            port: 
              number: 80
      - path: /bar
        pathType: Prefix
        backend:
          service:
            name: echo
            port: 
              number: 80
' | kubectl apply -f -
```

**Response**

```
ingress.extensions/demo created
```


#### Verify endpoints
Test access to the http service and echo service

**Request**

```bash
curl -i $DATA_PLANE_LB/foo/status/200
```

**Response**
```bash

```

**Request**
```bash
curl -i $DATA_PLANE_LB/bar
```

**Response**

```
HTTP/1.1 200 OK

        method=GET
        real path=/
        query=
        request_version=1.1
        request_scheme=http
        request_uri=http://10.108.140.182:8080/

Request Headers:
        accept=*/*
        connection=keep-alive
        host=10.108.140.182
        user-agent=curl/7.29.0

        x-forwarded-proto=http
        x-real-ip=10.32.0.1

Request Body:
        -no body in request-
```

#### Results

A response with  HTTP/1.1 200 OK proxied Via: kong/2.x for both requests indicates the ingress rule is configured.



#### Add ingress resource for httpbin service
Let's add an Ingress resource which proxies requests to  /baz to the httpbin service. 

We will use this path later.

**NOTE** This is the new syntax for Kubernetes version 1.22 onwards

```bash
echo '
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: demo-2
  annotations:
    konghq.com/strip-path: "true"
    kubernetes.io/ingress.class: kong
spec:
  rules:
  - http:
      paths:
      - path: /baz
        pathType: Prefix
        backend:
          service:
            name: httpbin
            port: 
              number: 80
' | kubectl apply -f -
```

**Response**
```
ingress.extensions/demo-2 created
```
