⚠ ATTENTION: Apache Log4j 2 advisory.
Due to vulnerabilities present in earlier versions of Log4j 2, we have taken down all affected container images. We highly recommend all demos and forks to now use images from releases >= v0.3.4.
Online Boutique is a cloud-native microservices demo application. Online Boutique consists of a 10-tier microservices application. The application is a web-based e-commerce app where users can browse items, add them to the cart, and purchase them.
Google uses this application to demonstrate use of technologies like Kubernetes/GKE, Istio, Stackdriver, gRPC and OpenCensus. This application works on any Kubernetes cluster, as well as Google Kubernetes Engine. It’s easy to deploy with little to no configuration.
If you’re using this demo, please ★Star this repository to show your interest!
👓Note to Googlers: Please fill out the form at go/microservices-demo if you are using this application.

- Create a Google Cloud Platform project or use an existing project. Set the
PROJECT_IDenvironment variable and ensure the Google Kubernetes Engine and Cloud Operations APIs are enabled.
the clusters are created already
- Clone this repository ###test1
git clone https://github.com/joca318/online-boutique.git
cd online-boutique
- Access GKE cluster ASM0[1-2]
_ZONE_1=us-central1-c
_CLUSTER_1=asm01

gcloud container clusters get-credentials --zone=$_ZONE_2 $_CLUSTER_2 --project $_PROJECT_ID_2
- Deploy the sample app to the clusters [ASM0[1-2]
gcloud builds submit --config=cloudbuild-kubectl-testbinauthz.yaml --substitutions=_ZONE_2=us-east1-c,_PROJECT_ID_2=d-iot-gpa01,_CLUSTER_2=asm02,_ZONE_1=us-central1-c,_PROJECT_ID_1=service-project-256014,_CLUSTER_1=asm01,_PROJECT_ID=service-project-256014,_SEVERITY=HIGH
The binauthz uses the SEVERITY to Deploy the sample app to the clusters. [ASM0[1-2]. If the Severity is set to LOW, the binautz will block the deploy and show an error message:
Starting Step #1 - "severity check"

- Wait for the Pods to be ready.
kubectl get pods
After a few minutes, you should see:

- Access the web frontend in a browser using the frontend's
EXTERNAL_IP.
kubectl get svc -n frontend -l istio=ingressgateway'
Example output - do not copy
EXTERNAL-IP
<your-ip>
Note- you may see <pending> while GCP provisions the load balancer. If this happens, wait a few minutes and re-run the command.
- [Optional] Clean up:
skaffold delete -f skaffold-modules-deploy.yaml --kube-context=asm01
skaffold delete -f skaffold-modules-deploy.yaml --kube-context=asm02
to deploy using Cloud Deploy. we can execute the script deploy.sh. This one will create a simple pipeline with 2 targets
Online Boutique is composed of 11 microservices written in different languages that talk to each other over gRPC. See the Development Principles doc for more information.
Find Protocol Buffers Descriptions at the ./pb directory.
| Service | Language | Description |
|---|---|---|
| frontend | Go | Exposes an HTTP server to serve the website. Does not require signup/login and generates session IDs for all users automatically. |
| cartservice | C# | Stores the items in the user's shopping cart in Redis and retrieves it. |
| productcatalogservice | Go | Provides the list of products from a JSON file and ability to search products and get individual products. |
| currencyservice | Node.js | Converts one money amount to another currency. Uses real values fetched from European Central Bank. It's the highest QPS service. |
| paymentservice | Node.js | Charges the given credit card info (mock) with the given amount and returns a transaction ID. |
| shippingservice | Go | Gives shipping cost estimates based on the shopping cart. Ships items to the given address (mock) |
| emailservice | Python | Sends users an order confirmation email (mock). |
| checkoutservice | Go | Retrieves user cart, prepares order and orchestrates the payment, shipping and the email notification. |
| recommendationservice | Python | Recommends other products based on what's given in the cart. |
| adservice | Java | Provides text ads based on given context words. |
| loadgenerator | Python/Locust | Continuously sends requests imitating realistic user shopping flows to the frontend. |
