BookInfo gateway ingress is not getting a load balancer #219
Description
I have followed the instructions on GKE.
- https://istio.io/docs/tasks/installing-istio.html
- then ran the kubectl apply to install BookInfo: https://istio.io/docs/tasks/installing-istio.html
- it supposedly created a k8s Ingress resource named
gateway:
kubectl apply -f <(istioctl kube-inject -f bookinfo.yaml)
service "details" created
deployment "details-v1" configured
service "ratings" created
deployment "ratings-v1" configured
service "reviews" created
deployment "reviews-v1" configured
deployment "reviews-v2" configured
deployment "reviews-v3" configured
service "productpage" created
deployment "productpage-v1" configured
ingress "gateway" configured
$ kubectl get ing

Problems
- The external IP address does not work.
- No Load Balancers created for this ingress.
- No events for this Ingress in
kubectl get events. - This ingress output is not normal, see the ingress below for an example:
$ kubectl describe ing basic-ingress
Name: basic-ingress
Namespace: default
Address: 35.190.22.239
Default backend: nginx:80 (10.8.4.5:80)

I am guessing ingress/gateway resource is not getting prepared by the GKE ingress controller because the target service/productpage is not exposed with type: NodePort (it's type: ClusterIP).
$ kd svc productpage

When I look at events via:
kubectl get events -w | grep -i Ingress
I see nothing about the gateway Ingress in the events.
Can someone verify the instructions for tomorrow‘s hackathon?
