docker容器网络更改

由于粗心大意导致在创建容器时候把网络指定错了 如何在不删除容器的情况下更改容器网络呢

更改网络

###解除容器绑定的网络 网络名词mynetwork 容器名称 lnmp
[root@lnmp tp6cms]# docker network disconnect mynetwork lnmp
##删除原先的网络
[root@lnmp tp6cms]# docker network rm mynetwork
##重新创建容器网络
[root@lnmp tp6cms]# docker network create --subnet=192.168.222.0/24 mynetwork
7d40e0be1fcade91f8109a54a05bf0f012584e0bbb9449bec5335db247efd0be
##为容器重新指定网络
[root@lnmp tp6cms]# docker network connect mynetwork lnmp 
##重新启动容器
[root@lnmp tp6cms]# docker container restart lnmp

查看效果

[root@lnmp tp6cms]# docker exec -it lnmp bash
