📚 Welcome to Day 51!
In this final part of our 3-part Kubernetes Ingress series, we take our setup from Part 2 and enhance it with TLS termination and subdomain-based routing on Amazon EKS using the AWS Load Balancer Controller (ALB Ingress Controller).
You’ll see how to secure workloads with valid TLS certificates from AWS Certificate Manager, configure Route 53 DNS records, and route traffic intelligently based on subdomains like iphone.cwvj.click and android.cwvj.click — all while using a single ALB.
🛠 What You’ll Learn:
✅ Registering a domain with Route 53
✅ Requesting & validating TLS certificates via ACM
✅ Updating Ingress manifests for HTTPS enforcement
✅ Manual DNS setup for apex and subdomains in Route 53
✅ Host-based (name-based) routing in Kubernetes Ingress
✅ Multi-domain certificate handling & ALB SNI support
✅ End-to-end testing via browser & AWS Console
💡 By the end of this lecture:
You’ll know how to build a production-ready Ingress gateway on Amazon EKS that secures traffic with HTTPS, supports multiple domains and subdomains, and routes requests at the hostname level — all powered by AWS-native services.
