ingress-nginx與nginx ingress不是一個東西
Categories:
看了兩週的文檔才發現 Ingress-Nginx 和 Nginx Ingress 不是同一個東西, 兩者的功能和實現方式都不一樣. 並且還有指導遷移的文檔.
Ingress-NGINX 是社區版, 參與討論的人數更多, 搜索到的答案更多. NGINX Ingress 是商業版, 功能更多, 但是社區參與度更低.
根據 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 可以通過 NGINX Open Source 免費使用. 付費客戶可以通過 NGINX Plus 訪問 NGINX Ingress Controller.
另外 nginx 的商業版官網已遷移至www.f5.com
Nginx Ingress Controller 的產品頁在https://www.f5.com/products/nginx/nginx-ingress-controller
