Differences Between nginxinc/kubernetes-ingress and kubernetes/ingress-nginx Ingress Controllers

有两个基于NGINX的Ingress控制器实现：你可以在这个repo中找到的那个（nginxinc / kubernetes-ingress）和一个来自kubernetes / ingress-nginx repo的实现。在本文档中，我们将解释这些实现之间的主要区别。此信息可帮助您根据需求选择适当的实现，或从一个实现转移到另一个实现。

我用的是哪一个？

如果您不确定正在使用哪个实现，请检查正在运行的Ingress控制器的容器映像。对于nginxinc / kubernetes-ingress Ingress控制器，其Docker镜像在DockerHub上发布，可作为nginx / nginx-ingress使用。

关键差异

下表总结了nginxinc / kubernetes-ingress和kubernetes / ingress-nginx Ingress控制器之间的主要区别。请注意，该表有两列用于nginxinc / kubernetes-ingress Ingress控制器，因为它可以与NGINX和NGINX Plus一起使用。有关使用NGINX Plus的nginxinc / kubernetes-ingress的更多信息，请阅读此处。
