After,

And also delete the different objects we've created:

kubectl --context ${MGMT} -n bookinfo-team delete virtualdestination productpage
kubectl --context ${MGMT} -n bookinfo-team delete outlierdetectionpolicy outlier-detection

• We should also delete the failoverpolicy

• Also, When we switch back to the original RT before the Zero Trust section of module 2, we should add a note on why we are switching back

• Making this command and others multiline would improve readability-

pod=$(kubectl --context ${CLUSTER1} -n httpbin get pods -l app=not-in-mesh -o jsonpath='{.items[0].metadata.name}')
kubectl --context ${CLUSTER1} -n httpbin debug -i -q ${pod} --image=curlimages/curl -- curl -s -o /dev/null -w "%{http_code}" http://reviews.bookinfo-backends.svc.cluster.local:9080/reviews/0

• Rather than doing a kubectl debug, it might be easier to do this via a sleep pod
  Current:

pod=$(kubectl --context ${CLUSTER1} -n httpbin get pods -l app=in-mesh -o jsonpath='{.items[0].metadata.name}')
kubectl --context ${CLUSTER1} -n httpbin debug -i -q ${pod} --image=curlimages/curl -- curl -s -o /dev/null -w "%{http_code}" http://reviews.bookinfo-backends.svc.cluster.local:9080/reviews/0

Proposed:

kubectl --context $CLUSTER1 -n httpbin \
apply -f https://raw.githubusercontent.com/istio/istio/release-1.17/samples/sleep/sleep.yaml

kubectl --context $CLUSTER1 -n httpbin \
get pod -l app=sleep;

kubectl --context $CLUSTER1 -n httpbin \
exec -it deploy/sleep -- \
curl -s -o /dev/null -w "%{http_code}" http://reviews.bookinfo-backends.svc.cluster.local:9080/reviews/0

We should break the following section into 3 separate sections

pod=$(kubectl --context ${CLUSTER1} -n bookinfo-frontends get pods -l app=productpage -o jsonpath='{.items[0].metadata.name}')
echo "From productpage to details, should be allowed"
kubectl --context ${CLUSTER1} -n bookinfo-frontends debug -i -q ${pod} --image=curlimages/curl -- curl -s http://details.bookinfo-backends:9080/details/0 | jq

echo "From productpage to reviews, should be allowed"
kubectl --context ${CLUSTER1} -n bookinfo-frontends debug -i -q ${pod} --image=curlimages/curl -- curl -s http://reviews.bookinfo-backends:9080/reviews/0 | jq

echo "From productpage to ratings, should be denied"
kubectl --context ${CLUSTER1} -n bookinfo-frontends debug -i -q ${pod} --image=curlimages/curl -- curl -s http://ratings.bookinfo-backends:9080/ratings/0 -i

Module 3

If you refresh your browser, you should see that you get a response either from the local service or from the external service.

solution

• restart the deployment so that it picks the new cert from istio
  kubectl --context $CLUSTER1 -n httpbin rollout restart deployment/in-mesh
