ARCHITECTURE CHANGES:
- API service: Node.js server on port 3001 (Dockerfile.api)
- Frontend service: Nginx serving React on port 80 (Dockerfile.frontend)
- Each service has its own deployment, service, and replicas
- Ingress routes / to frontend and /api/ to API
KUBERNETES MANIFESTS:
- api-deployment.yaml: 2 replicas of Node.js API server
- api-service.yaml: ClusterIP service for API
- frontend-deployment.yaml: 2 replicas of Nginx frontend
- frontend-service.yaml: ClusterIP service for frontend
- Updated ingress.yaml: Routes traffic based on paths
- Updated kustomization.yaml: References new deployments
DOCKER IMAGES:
- Dockerfile.api: Minimal Node.js image for API (~200MB)
- Dockerfile.frontend: Nginx + React build (~50MB)
- Separate builds in workflow for independent versioning
NGINX CONFIGURATION:
- Removed API proxy (separate service now)
- Simplified config for static file serving only
BENEFITS:
- Independent scaling (can scale frontend/API separately)
- Smaller images with minimal base images
- API errors don't affect frontend availability
- Easier to update one service without affecting the other
