ingress-nginx and nginx ingress are not the same thing

After two weeks of reading the documentation, I finally realized that Ingress-Nginx and Nginx Ingress are not the same thing. Their functionality and implementation methods are different. There is even documentation to guide migration.

• Migrating from the Ingress-NGINX Controller to the NGINX Ingress Controller
• NGINX Ingress Controller
• Ingress-NGINX

Ingress-NGINX is the community version, with more people participating in discussions and more answers available from searches. NGINX Ingress is the commercial version, with more features but lower community participation.

According to Deploy with NGINX Ingress Controller - Overview

NGINX Ingress Controller can be used for free with NGINX Open Source. Paying customers have access to NGINX Ingress Controller with NGINX Plus. To deploy NGINX Ingress Controller with NGINX Service Mesh, you must use either:

Open Source NGINX Ingress Controller version 3.0+ NGINX Plus version of NGINX Ingress Controller Visit the NGINX Ingress Controller product page for more information.

NGINX Ingress Controller can be used for free with NGINX Open Source. Paying customers can access NGINX Ingress Controller through NGINX Plus.

Additionally, the official website for the commercial version of Nginx has been migrated to www.f5.com

The product page for Nginx Ingress Controller is at https://www.f5.com/products/nginx/nginx-ingress-controller
