"navigating-nginx-ingress-retirement.md": "A practical guide for migrating from NGINX Ingress Controller to AWS Load Balancer Controller on Amazon EKS, prompted by the announced retirement of Ingress NGINX in March 2026. Covers: how to detect if clusters are affected (kubectl command to check for ingress-nginx pods); architectural differences between NGINX Ingress (in-cluster reverse proxy) and AWS Load Balancer Controller (provisions native ALB/NLB outside the cluster); feature comparison including AWS-native integrations (ACM, WAF, Shield, Cognito/OIDC), operational differences, and cost models; step-by-step migration walkthrough using rewrite.bar.com example demonstrating URI rewrite migration (NGINX rewrite-target annotation to ALB transforms annotation with url-rewrite config) and TLS termination migration (Kubernetes Secrets to ACM certificates with certificate-arn or certificate-discovery annotations); SSL redirect and policy configuration; pre-migration, during-migration, and post-migration checklists; recommendation to adopt Kubernetes Gateway API as the next-generation standard (supported by AWS Load Balancer Controller v3.0); and next steps including cluster audit, configuration assessment, proof of concept, and engaging AWS support."
