Kubernetes Ingress NGINX Retirement and Gateway API Migration Guide

Kubernetes Ingress NGINX Retirement and Gateway API Migration The NGINX Ingress Controller, one of Kubernetes' most widely-used components, is transitioning from active development to maintenance mode. The Kubernetes community is now emphasizing the new Gateway API standard. For teams running NGINX Ingress in production, understanding this migration path is essential. NGINX Ingress → Gateway API: Why the shift? NGINX Ingress was designed as a standalone solution. However, as Kubernetes matured, native service networking evolved.
