====================================
Kubernetes Ingress比较
====================================

:ref:`ingress` 提供了:

- 负载均衡
- HTTP/HTTPS请求映射
- SSL/TLS终止(termination)

使得 :ref:`k8s_services` 通过安全可达的域和URL暴露(expose)，这样Kubernetes生产环境中expose服务变得简单易行。

请注意 :ref:`k8s_loadbalancer_ingress` ，Ingress工作在OSI的第7层，也就是应用层，所以提供了HTTP/HTTPS请求的检查能力。同时，Ingress也提供了无需负载均衡就能向外提供服务资源(虽然通常会结合 LoadBalancer 和 Ingress)。

常用Ingress
