1.docker网桥自定义配置
[root@yyx2 yum.repos.d]# vim /etc/docker/daemon.json //进入网桥配置文件
{
"registry-mirrors": ["https://docker.mirrors.ustc.edu.cn/"], //这里一定要加上,
"bip":"181.181.181.1/24" }
//写入以上内容
[root@yyx2 ~]# systemctl daemon-reload //重新载入配置文件
[root@yyx2 ~]# systemctl restart docker //重启docker服务
[root@yyx2 ~]# docker run -itd --name yyx busybox //启动一个容器
bada7ecc9e7ffbb79eb11b7fd8762daba4b366e5f80ba15d744a49dfeadccba3
[root@yyx2 ~]# docker ps //查看容器

[root@yyx2 ~]# docker inspect yyx1 //查看yyx1的信息
