Load balance Ingress traffic with Citrix ADC CPX in Minikube

# Load balance Ingress traffic with Citrix ADC CPX in Minikube

In this example, the Citrix ADC CPX (a containerized form-factor) is used to route the Ingress traffic to a `Guestbook` microservice application deployed in a Minikube cluster.
An Ingress resource is deployed in the MiniKube cluster to define the rules for sending external traffic to the application.

**Prerequisite**:

 Ensure that you have installed and set up a Minikube cluster (This example is tested on Minikube v1.23 having K8s 1.22.1 deployed).

Perform the following: 

1. Deploy Citrix ADC CPX as an Ingress proxy in the Minikube cluster and verify the installation using the following commands.


      kubectl create -f https://raw.githubusercontent.com/citrix/cloud-native-getting-started/master/beginners-guide/manifest/cpx.yaml
       
      kubectl get pods -l app=cpx-ingress


2. Deploy the `Guestbook` application in Minikube and verify the installation.


       kubectl create -f https://raw.githubusercontent.com/citrix/cloud-native-getting-started/master/beginners-guide/manifest/guestbook-app.yaml

       kubectl get pods -l 'app in (guestbook, redis)'


3. Deploy an Ingress rule that sends traffic to http://www.guestbook.com.


       kubectl create -f https://raw.githubusercontent.com/citrix/cloud-native-getting-started/master/beginners-guide/manifest/guestbook-ingress.yaml

       kubectl get ingress

       kubectl get svc cpx-service


4. Send traffic to the `Guestbook` microservice application.

       curl -s -H "Host: www.guestbook.com" http://<MiniKube IP:<NodePort> | grep Guestbook


5. (Optional) Clean up the deployments using the following commands.


       kubectl delete -f https://raw.githubusercontent.com/citrix/cloud-native-getting-started/master/beginners-guide/manifest/cpx.yaml

       kubectl delete -f https://raw.githubusercontent.com/citrix/cloud-native-getting-started/master/beginners-guide/manifest/guestbook-app.yaml

       kubectl delete -f https://raw.githubusercontent.com/citrix/cloud-native-getting-started/master/beginners-guide/manifest/guestbook-ingress.yaml
