Ingress概述

Ingress 是对集群中服务的外部访问进行管理的 API 对象,典型的访问方式是 HTTP和HTTPS。

Ingress 可以提供负载均衡、SSL 和基于名称的虚拟托管。

必须具有 ingress 控制器【例如 ingress-nginx】才能满足 Ingress 的要求。仅创建 Ingress 资源无效。

Ingress 是什么

Ingress 公开了从集群外部到集群内 services 的 HTTP 和 HTTPS 路由。 流量路由由 Ingress 资源上定义的规则控制。

1  internet
2 |
3 [ Ingress ]
4 --|-----|--
5 [ Services ]

可以将 Ingress 配置为提供服务外部可访问的 URL、负载均衡流量、 SSL / TLS,以及提供基于名称的虚拟主机。Ingress 控制器 通常负责通过负载均衡器来实现 Ingress,尽管它也可以配置边缘路由器或其他前端来帮助处理流量。

Ingress 不会公开任意端口或协议。若将 HTTP 和 HTTPS 以外的服务公开到 Internet 时,通常使用 Service.Type=NodePort 或者 Service.Type=LoadBalancer 类型的服务。

以Nginx Ingress为例,图如下

Ingress示例

部署Ingress-Nginx

该Nginx是经过改造的,而不是传统的Nginx。

Ingress-Nginx实现Rewrite重写

官网地址:

https://kubernetes.github.io/ingress-nginx/examples/rewrite/

重写可以使用以下注解控制:

名称 描述
nginx.ingress.kubernetes.io/rewrite-target 必须重定向的目标URL String
nginx.ingress.kubernetes.io/ssl-redirect 指示位置部分是否只能由SSL访问(当Ingress包含证书时,默认为True) Bool
nginx.ingress.kubernetes.io/force-ssl-redirect 即使Ingress没有启用TLS,也强制重定向到HTTPS Bool
nginx.ingress.kubernetes.io/app-root 定义应用程序根目录,Controller在“/”上下文中必须重定向该根目录 String
nginx.ingress.kubernetes.io/use-regex 指示Ingress上定义的路径是否使用正则表达式 Bool
