docker0自定义网络
查看所有的网络
[root@iz8g9301trfnpxz home]# docker network ls
NETWORK ID NAME DRIVER SCOPE
68c30b64280c bridge bridge local
e5373821382b host host local
bc64d000f692 none null local
网络模式
| 网络模式 | 解释 |
|---|---|
| bridge | 桥接docker(默认,自己创建也是bridge模式) |
| none | 不配置网络 |
| host | 和宿主机共享网络 |
| container | 容器网络连通!(用的少!局限很大) |
测试
# 我们直接启动的命令 --net bridge ,而这个就是我们的docker0
[root@iz8g9301trfnpxz home]# docker run -d -P --name tomcat01 tomcat
[root@iz8g9301trfnpxz home]# docker run -d -P --name tomcat01 --net bridge tomcat

# docker0 特点: 默认,域名不能访问,--link可以打通连接!
# 我们可以自定义一个网络!
# --driver bridge
# --subnet 192.168.0.0/16 192.168.0.2
# --gateway 192.168.0.1
[root@iz8g9301trfnpxz home]# docker network create --driver bridge --subnet 192.168.0.0/16 --gateway 192.168.0.1 mynet
