Bookinfo Sample

See https://istio.io/docs/examples/bookinfo/.

Note: We need the owner of the PR to perform the appropriate testing with built/pushed images to their own docker repository before we would build/push images to the official Istio repository.

Build docker images

cd samples/bookinfo
src/build-services.sh <version> <prefix>

Where <version> is the tag and <prefix> is the docker registry to tag the images.

For example:

$ src/build-services.sh 1.16.3 docker.io/shamsher31
Sending build context to Docker daemon  1.218MB
Step 1/16 : FROM python:3.7.7-slim
3.7.7-slim: Pulling from library/python
8559a31e96f4: Pull complete
...
Successfully built 1b293582cc2e
Successfully tagged shamsher31/examples-bookinfo-ratings-v2:1.16.3
Successfully tagged shamsher31/examples-bookinfo-ratings-v2:latest

The bookinfo versions are different from Istio versions since the sample should work with any version of Istio.

Push docker images to docker hub

After the local build is successful, you need to update the YAML file with the latest tag that you used during the build eg: 1.16.3.

Run the following script to build the docker images, push them to docker hub, and to update the YAML files in one step.

./build_push_update_images.sh <version> <prefix>

For example:

$ ./build_push_update_images.sh 1.16.3 --prefix=shamsher31
...
1.16.3: digest: sha256:70634d3847a190b9826975c8 size: 3883
Pushing: shamsher31/examples-bookinfo-reviews-v2:1.16.3
The push refers to a repository [docker.io/shamsher31/examples-bookinfo-reviews-v2]
...

Verify that expected tag eg: 1.16.3 is updated in platform/kube/bookinfo*.yaml files.

Tests

Test that the bookinfo samples work with the latest tag eg: 1.16.3 that you pushed.

$ cd ../../
$ kubectl apply -f samples/bookinfo/platform/kube/bookinfo.yaml
serviceaccount/bookinfo-details created
deployment.apps/details-v1 created
serviceaccount/bookinfo-ratings created
...

Wait for all the pods to be in Running start.

$ kubectl get pods
NAME                              READY   STATUS    RESTARTS   AGE
details-v1-7f556f5c6b-485l2       2/2     Running   0          10m
productpage-v1-84c8f95c8d-tlml2   2/2     Running   0          10m
ratings-v1-66777f856b-2ls78       2/2     Running   0          10m

reviews-v3-7f69dd7fd4-zjvc8       2/2     Running   0          10m

Once all the pods are in the Running state. Test if the bookinfo works through cli.

$ kubectl exec -it "$(kubectl get pod -l app=ratings -o jsonpath='{.items[0].metadata.name}')" -c ratings -- curl productpage:9080/productpage | grep -o "<title>.*</title>"
<title>Simple Bookstore App</title>

You can also test it by hitting productpage in the browser.

http://192.168.39.116:31395/productpage

You should see the following in the browser.

Note: If everything works as mentioned above, request a new official set of images be built and pushed from the reviewer, and add another commit to the original PR with the version changes.

Bookinfo is tested by istio.io integration tests. You can find them under tests in the istio/istio.io repository.
