 Now that you have a continuously running, replicated application you can expose it on a network. Before discussing the Kubernetes approach to networking, it is worthwhile to contrast it with the "normal" way networking works with Docker.
 
-By default, Docker uses host-private networking, so containers can talk to other containers only if they are on the same machine. In order for Docker containers to communicate across nodes, there must be allocated ports on the machine’s own IP address, which are then forwarded or proxied to the containers. This obviously means that containers must either coordinate which ports they use very carefully or ports must be allocated dynamically.

This obviously means that containers must either coordinate which ports they use very carefully or ports must be allocated dynamically.
 
-Coordinating ports across multiple developers is very difficult to do at scale and exposes users to cluster-level issues outside of their control. Kubernetes assumes that pods can communicate with other pods, regardless of which host they land on. We give every pod its own cluster-private-IP address so you do not need to explicitly create links between pods or map container ports to host ports. This means that containers within a Pod can all reach each other's ports on localhost, and all pods in a cluster can see each other without NAT. The rest of this document will elaborate on how you can run reliable services on such a networking model.

 默认情况下，Docker 使用私有主机网络连接，只能与同在一台机器上的容器进行通信。
 为了实现容器的跨节点通信，必须在机器自己的 IP 上为这些容器分配端口，为容器进行端口转发或者代理。
 
-多个开发人员之间协调端口的使用很难做到规模化，那些难以控制的集群级别的问题，都会交由用户自己去处理。
