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。
internet|[ Ingress ]--|-----|--[ 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

部署Ingress-Nginx
该Nginx是经过改造的，而不是传统的Nginx。

重写可以使用以下注解控制：

| 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 |
