nginx.ingress.kubernetes.io/auth-type: basic 和 nginx.ingress.kubernetes.io/auth-secret: basic-auth 指定了认证的方式为 Basic，认证秘钥为 basic-auth 。
4. 访问服务
域名即为 Ingress 中配置的 hosts，这里是 longhorn.chenshaowen.com
由于 Ingress Controller 将其 80 端口映射到主机的 30914 ，因此服务的访问地址为 longhorn.chenshaowen.com:30914。
上图输入账户 admin，密码 xxxxx 之后即可查看服务。如下图:
