本文详细介绍了Docker网络配置中的docker0接口默认设置，并展示了如何通过修改daemon.json文件来指定自定义的IP地址和子网掩码。此教程有助于理解Docker内部网络的工作原理。

   docker0默认信息如下:

 docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN 
    link/ether 02:42:a6:db:21:70 brd ff:ff:ff:ff:ff:ff
    inet 172.17.0.1/16 scope global docker0
       valid_lft forever preferred_lft forever

   修改/etc/docker/daemon.json，增加如下配置信息，

{"bip": "180.18.0.1/24"}

   daemon.json完整的配置信息如下：
