Here are the steps that will work:

curl -L https://git.io/getLatestIstio | sh -
cd istio-0.7.1/
kubectl apply -f install/kubernetes/istio.yaml
Create route rules

• Do we need any other annotations on existing manifest?
• Do we necessarily need an Ingress controller? Will this not work with ELB?
• Do we have to inject Envoy as sidecar? Isn't it only for pod-to-pod communication? Is it required for canary or blue/green?
