Deploy Your First Component

This guide walks you through deploying your first component on OpenChoreo. By the end of this tutorial, you'll have a running web service accessible through the platform, complete with monitoring and security configured automatically.

Prerequisites​

Before you begin, ensure you have:

  • OpenChoreo installed in your Kubernetes cluster (see On Self-Hosted Kubernetes or go to production with Single Cluster or Multi Cluster setup)
  • kubectl configured to access your cluster
  • kubectl context set to your cluster (should be k3d-openchoreo if following the k3d setup)

Step 1: Verify Your Setup​

First, make sure you have set up OpenChoreo on your cluster following one of the installation guides.

You should see all OpenChoreo components running with the control plane and data plane pods in Running status.

Step 2: Deploy the Go Greeter Service​

For this tutorial, we'll use the Go Greeter Service sample that comes with OpenChoreo. This is a simple web service that demonstrates OpenChoreo's core capabilities.

kubectl apply -f https://raw.githubusercontent.com/openchoreo/openchoreo/release-v0.8/samples/from-image/go-greeter-service/greeter-service.yaml

This single command creates:

  • Component: Defines the application and its requirements (references the deployment/service ComponentType)
  • Workload: Specifies the container image and runtime configuration
  • ReleaseBinding: Deploys the component to the development environment
  • SecretReference: Manages external secrets for the component

Step 3: Monitor the Deployment​

Check that all resources are created:

kubectl get component,workload,releasebinding -A

Check the component status:

kubectl get component greeter-service

Monitor the component deployment:

kubectl get releasebinding greeter-service-development

Step 4: Verify the Deployment​

Wait for the service to be ready (this may take 1-2 minutes).

Check the actual Kubernetes deployment:

kubectl get deployment -A | grep greeter

Verify pods are running:

kubectl get pods -A | grep greeter

Check HTTP routes are configured:

kubectl get httproute -A -o wide

Step 5: Test Your Application​

Test the greeter service endpoint:

curl http://development.openchoreoapis.localhost:19080/greeter-service/greeter/greet

You should receive a successful response:

Hello, Stranger!

You can also test with a name parameter:

curl http://development.openchoreoapis.localhost:19080/greeter-service/greeter/greet?name=OpenChoreo

Expected output:

Hello, OpenChoreo!

This confirms that:

  • Your component is deployed and running
  • The API gateway is properly configured
  • Network routing is working correctly
  • Security policies are applied automatically

Step 6: Explore What OpenChoreo Created​

Let's examine what OpenChoreo automatically created for your component.

View the OpenChoreo resources:

kubectl get component,workload,releasebinding -n default

Check the underlying Kubernetes resources:

kubectl get deployment,pod,svc -A | grep greeter

View the HTTP routing configuration:

kubectl describe httproute -A | grep -A 20 greeter

OpenChoreo automatically created:

  • Component - High-level application definition (using the deployment/service ComponentType)
  • Workload - Container deployment specification
  • ReleaseBinding - Environment-specific deployment configuration
  • Deployment - Kubernetes deployment managing pods
  • Service - Kubernetes service for networking
  • HTTPRoute - Gateway API routing configuration
  • Secret - External secrets synchronized from the secret store

Summary​

You've successfully:

  • Deployed your first OpenChoreo component from a container image
  • Tested API access through the OpenChoreo gateway
  • Explored the resources OpenChoreo created automatically

Your application is now running in a production-ready environment with enterprise-grade security, networking, and observability—all configured automatically by OpenChoreo!

Clean Up​

To remove the sample application:

kubectl delete -f https://raw.githubusercontent.com/openchoreo/openchoreo/release-v0.8/samples/from-image/go-greeter-service/greeter-service.yaml
