Lab 3 Appendix: Deploying Sample App with manual sidecar injection

To do a manual sidecar injection we will be using istioctl command:

curl https://raw.githubusercontent.com/istio/istio/master/samples/bookinfo/platform/kube/bookinfo.yaml | istioctl kube-inject -f - > newBookInfo.yaml

Observing the new yaml file reveals that additional container Istio Proxy has been added to the Pods with necessary configurations:

        image: docker.io/istio/proxyv2:1.3.0
        imagePullPolicy: IfNotPresent
        name: istio-proxy

We need to now deploy the new yaml using kubectl

kubectl apply -f newBookInfo.yaml

To do both in a single command:

kubectl apply -f <(curl https://raw.githubusercontent.com/istio/istio/master/samples/bookinfo/platform/kube/bookinfo.yaml | istioctl kube-inject -f -)

Now continue to Verify Bookinfo deployment.
