Google Microservices Demo Sample

This sample demonstrates how to deploy Google's microservices demo application using OpenChoreo.

Overview

This sample demonstrates a complete microservices architecture deployment using the Google Cloud Platform's microservices demo application. It showcases multiple services working together using OpenChoreo.

Pre-requisites

• Kubernetes cluster with OpenChoreo installed
• The kubectl CLI tool installed
• Docker runtime capable of running AMD64 images (see note below)

Note

Architecture Compatibility

This sample uses official Google Container Registry images built for AMD64 architecture. If you're on Apple Silicon (M1/M2) or ARM-based systems, your container runtime may need to emulate AMD64. To verify your setup can run AMD64 images:

docker run --rm --platform linux/amd64 hello-world

If this command fails, you may need to enable emulation support in your container runtime.

Step 1: Deploy the Application

From the repository root, deploy the project and all microservices components:

kubectl apply -f https://raw.githubusercontent.com/openchoreo/openchoreo/main/samples/gcp-microservices-demo/

This will create the project and deploy all the microservices using official Google Container Registry images.

Step 2: Expose the Frontend

Port forward the OpenChoreo gateway service to access the frontend locally:

kubectl port-forward -n openchoreo-data-plane svc/gateway-external 8443:443 &

Step 3: Test the Application

Access the frontend application in your browser:

https://frontend-development.choreoapps.localhost:8443

Tip

Verification

You should see the Google Cloud Platform microservices demo store frontend with:

• Product catalog
• Shopping cart functionality
• Checkout process

Clean Up

Stop the port forwarding and remove all resources:

# Find and stop the specific port-forward process
pkill -f "port-forward.*gateway-external.*8443:443"

# Remove all resources
kubectl delete -f https://raw.githubusercontent.com/openchoreo/openchoreo/main/samples/gcp-microservices-demo/
