Learn KNATIVE with Real Code Examples
Updated Nov 25, 2025
Practical Examples
Deploy a serverless API endpoint
Process CloudEvents from a message queue
Scale a microservice based on HTTP traffic
Run event-driven image processing service
A/B testing with traffic splitting between revisions
Troubleshooting
Check pod status with `kubectl get pods -n knative-serving`
Validate event sources and triggers
Verify ingress configuration (Istio/Contour/Kourier)
Inspect logs with `kubectl logs`
Ensure proper RBAC permissions in cluster
Testing Guide
Test service locally with Minikube/Kind
Use `kubectl get ksvc` to verify deployment
Simulate events to validate triggers
Monitor scaling behavior
Integration tests with HTTP calls and event sources
Deployment Options
Deploy on Kubernetes clusters (on-prem or cloud)
Use OpenShift for enterprise deployments
Integrate with CI/CD pipelines for automated deployments
Containerized microservices with Knative Serving
Event-driven serverless workloads
