ingress-nginx与nginx ingress不是一个东西
Categories:
看了两周的文档才发现 Ingress-Nginx 和 Nginx Ingress 不是同一个东西, 两者的功能和实现方式都不一样. 并且还有指导迁移的文档.
Ingress-NGINX 是社区版, 参与讨论的人数更多, 搜索到的答案更多. NGINX Ingress 是商业版, 功能更多, 但是社区参与度更低.
根据 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:
