🔹 Kubernetes - Ingress NGINX Retirement: What You Need to Know

The blog post announces the upcoming retirement of Ingress NGINX by Kubernetes SIG Network and the Security Response Committee to ensure ecosystem safety and security.

Users are advised to transition to alternatives like the Gateway API, the modern replacement for Ingress, or other Ingress controllers listed in Kubernetes documentation. Ingress NGINX faced maintenance challenges due to limited support and changing expectations about cloud-native software, leading to its retirement decision. The community and maintainers are thanked for their contributions, and users are urged to start migrating to other solutions to ensure continued functionality and security. 👉 Read more
