桥接：虚拟机直接连接外部的物理网络，主机起到了网桥的作用，虚拟机可以直接访问外网，并且是透明的。

[root@node001 ~]# P068【68_docker network能干嘛】03:09
docker network 作用：
- 容器间的互联和通信以及端口映射
- 容器IP变动时候可以通过服务名直接网络通信而不受到影响
P069【69_docker network网络模式有几种】03:48
P070【70_docker network底层ip和容器映射变化】06:16
结论：docker容器内部的ip是有可能会发生改变的。

container⽹络模式
新建的容器和已经存在的一个容器共享一个网络ip配置而不是和宿主机共享。新创建的容器不会创建自己的网卡，配置自己的IP，而是和一个指定的容器共享IP、端口范围等。同样，两个容器除了网络方面，其他的如文件系统、进程列表等还是隔离的。
