Stack Overflow Replaces NGINX-Ingress in Production — Used Claude to Analyze Ingress Objects, Evaluated Gateway API

Stack Overflow Blog·medium signal

After NGINX-Ingress was announced as retiring, Stack Overflow documented their migration process across production Kubernetes clusters. They exported all ingress objects to YAML and used Claude to analyze and sort them into use-case buckets. Traefik's annotation compatibility proved insufficient; F5 NGINX's reliance on non-standard resources was a dealbreaker. They narrowed to Gateway API implementations as the primary path forward. A practical migration playbook for any team facing the same deadline.
