Kubernetes Ingress is the gateway for routing external traffic to services in your cluster. It manages HTTP and HTTPS access, enforces rules, and integrates with load balancers. The onboarding process defines how fast you can move from local development to production-ready routing without manual hacks.
Step 1: Prepare the Cluster
Ensure your Kubernetes cluster is healthy and reachable. Update configurations, confirm DNS resolution, and check that networking plugins are installed correctly. Ingress resources depend on stable cluster networking.
Step 2: Install an Ingress Controller
This is the engine behind the Ingress resource. Common choices are NGINX Ingress Controller or Traefik. Use Helm or YAML manifests to deploy. Verify deployment with kubectl get pods and confirm the controller logs show no errors.
Step 3: Configure Namespaces and Services
Place your applications in organized namespaces. Create Kubernetes Services for each app with correct ClusterIP or NodePort types. These Services will be targets for your Ingress rules.
Step 4: Define the Ingress Resource
Write a clear YAML definition that includes hostnames, paths, and service backends. Use annotations for TLS termination, rewrite-targets, and custom timeouts. Apply with kubectl apply -f ingress.yaml. Immediately check kubectl describe ingress to verify rule registration.
