1. Challenge

   Deploy Istio into a Kubernetes Cluster and Deploy the bookinfo Application

   Get the Istio installation package onto the Kube Master and unpack it:

   [cloud_user@km]$ wget https://github.com/istio/istio/releases/download/1.0.6/istio-1.0.6-linux.tar.gz
   
   [cloud_user@km]$ tar -xvf istio-1.0.6-linux.tar.gz
   

   Add istioctl to our path:

   [cloud_user@km]$ export PATH=$PWD/istio-1.0.6/bin:$PATH
   

   Set Istio to NodePort at port 30080:

   [cloud_user@km]$ sed -i 's/LoadBalancer/NodePort/;s/31380/30080/' ./istio-1.0.6/install/kubernetes/istio-demo.yaml
   

   Bring up the Istio control plane:

   [cloud_user@km]$ kubectl apply -f ./istio-1.0.6/install/kubernetes/istio-demo.yaml
   

   Verify that the control plane is running:

   [cloud_user@km]$ kubectl -n istio-system get pods
   

   When all of the pods are up and running (which we can verify by running that command again) we can move on.

   Install the bookinfo application with manual sidecar injection:

   [cloud_user@km]$ kubectl apply -f <(istioctl kube-inject -f istio-1.0.6/samples/bookinfo/platform/kube/bookinfo.yaml)
   

   Verify that the application is running and that there are 2 containers per pod:

   [cloud_user@km]$ kubectl get pods
   

   Ignore the busybox pod, that's part of the environment.

   Once everything is running, let's create an ingress and virtual service for the application:

   [cloud_user@km]$ kubectl apply -f istio-1.0.6/samples/bookinfo/networking/bookinfo-gateway.yaml
   

   Verify the page loads at the uri http://<kn1_IP ADDRESS>:30080/productpage

2. Challenge

   Verify That Routing Rules Are Working by Configuring the Application to Route to `v1` Then `v2` of the `reviews` Backend Service

   Set the default destination rules:

   [cloud_user@km]$ kubectl apply -f istio-1.0.6/samples/bookinfo/networking/destination-rule-all.yaml
   

   Route all traffic to version 1 of the application and verify that it is working:

   [cloud_user@km]$ kubectl apply -f istio-1.0.6/samples/bookinfo/networking/virtual-service-all-v1.yaml
   

   Update the virtual service file to point to version 2 of the service and verify that it is working. Edit istio-1.0.6/samples/bookinfo/networking/virtual-service-all-v1.yaml (using whatever text editor you like) and change this:

   - destination:
           host: reviews
           subset: v1
   

   to this:

   - destination:
           host: reviews
           subset: v2
