docker 网络Docker支持5种网络模式 bridge默认网络，Docker启动后默认创建一个docker0网桥，默认创建的容器也是添加到这个网桥中。 host容器不会获得一个独立的network namespace，而是与宿主机共用一个。 none获取独立的network namespace，但不为容器进行任何网络配置。 container与指定的容器使用同一个network namespace，网卡配置也都是相同的。-自定义自定义网桥，默认与bridge网络一样。 Linux IP信息包过滤原理：Docker主要通过netfilter/iptables实现网络通信。iptables由netfilter和iptables组成，netfilter组件是Linux内核集成的信息包过滤系统，它维护一个信息包过滤表，这个表用于控制信息包过滤处理的规则集。而iptables只是一个在用户空间的工具，用于增删改查这个过滤表的规则。 容器访问外部1234# iptables -t nat -nLChain POSTROUTING (policy ACCEPT)target p ...
