Online Boutique is a cloud-first microservices demo 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 how developers can modernize enterprise applications using Google Cloud products, including: Google Kubernetes Engine (GKE), Anthos Service Mesh (ASM), gRPC, Cloud Operations, Spanner, Memorystore, AlloyDB, and Gemini. This application works on any Kubernetes cluster.

Note to Googlers: Please fill out the form at go/microservices-demo.

Online Boutique is composed of 11 microservices written in different languages that talk to each other over gRPC.

1. Ensure you have the following requirements:

   • Google Cloud project.
   • Shell environment with gcloud, git, and kubectl.

2. Clone the latest major version.

   git clone --depth 1 --branch v0 https://github.com/GoogleCloudPlatform/microservices-demo.git
   cd microservices-demo/

   The --depth 1 argument skips downloading git history.

3. Set the Google Cloud project and region and ensure the Google Kubernetes Engine API is enabled.

   export PROJECT_ID=<PROJECT_ID>
   export REGION=us-central1
   gcloud services enable container.googleapis.com \
     --project=${PROJECT_ID}

   Substitute <PROJECT_ID> with the ID of your Google Cloud project.

4. Create a GKE cluster and get the credentials for it.

   gcloud container clusters create-auto online-boutique \
     --project=${PROJECT_ID} --region=${REGION}

   Creating the cluster may take a few minutes.

5. Deploy Online Boutique to the cluster.

   kubectl apply -f ./release/kubernetes-manifests.yaml

6. Wait for the pods to be ready.

   kubectl get pods

   After a few minutes, you should see the Pods in a Running state:

7. Access the web frontend in a browser using the frontend's external IP.

   kubectl get service frontend-external | awk '{print $4}'

   Visit http://EXTERNAL_IP in a web browser to access your instance of Online Boutique.

8. Congrats! You've deployed the default Online Boutique. To deploy a different variation of Online Boutique (e.g., with Google Cloud Operations tracing, Istio, etc.), see Deploy Online Boutique variations with Kustomize.

9. Once you are done with it, delete the GKE cluster.

   gcloud container clusters delete online-boutique \
     --project=${PROJECT_ID} --region=${REGION}

   Deleting the cluster may take a few minutes.
