istio: gateway: 0.8 httpbin sample task docs are not working with v1alpha3 https

I followed the gateway docs including setup tasks, and I get a 404 on http and a connection refused on https.

k8s: 1.9 in IBM Cloud istio version: istio-0.8.0-pre20180421-09-15

replication steps:

kubectl create ns istio-system

helm template --namespace=istio-system --set sidecar-injector.enabled=true install/kubernetes/helm/istio > sidecarinject.yaml

kubectl create -f sidecarinject.yaml

kubectl label namespace default istio-injection=enabled

kubectl create -f samples/httpbin/httpbin.yaml
