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

部署Ingress-Nginx

该Nginx是经过改造的，而不是传统的Nginx。

浏览器访问

hosts文件修改，添加如下信息

1文件位置：C:\WINDOWS\System32\drivers\etc\hosts
2添加信息如下：
3# K8S ingress学习
410.0.0.110  www.zhangtest.com  blog.zhangtest.com

 

浏览器访问www.zhangtest.com

1 http://www.zhangtest.com/
2 http://www.zhangtest.com/hostname.html

 

浏览器访问blog.zhangtest.com

1 http://blog.zhangtest.com/
2 http://blog.zhangtest.com/hostname.html

 

当然：除了用浏览器访问外，也可以在Linux使用curl访问。前提是修改/etc/hosts文件，对上面的两个域名进行解析。

Ingress-Nginx实现BasicAuth认证

官网地址：

https://kubernetes.github.io/ingress-nginx/examples/auth/basic/

 

准备工作

 1 [root@k8s-master ingress]# pwd
 2 /root/k8s_practice/ingress
 3 [root@k8s-master ingress]# yuminstall -y httpd
 4 [root@k8s-master ingress]# htpasswd -c auth foo
 5New password: #输入密码
 6 Re-type new password: #重复输入的密码
 7 Adding password for user foo   ##### 此时会生成一个 auth文件
 8 [root@k8s-master ingress]# kubectl create secret generic basic-auth --from-file=auth
 9 secret/basic-auth created
10 [root@k8s-master ingress]#

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：

名称描述值
nginx.ingress.kubernetes.io/rewrite-target必须重定向的目标URLString
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HTTPSBool
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
