docker网络错误(network bridge not found)_docker 网桥丢失_临江仙我亦是行人的博客-CSDN博客

问题：docker 没有网络模型了

root@sh-gpu102:~# docker run -it -d -v /mnt:/mnt -v /ssd:/ssd registry.test.cn/more/lite:2.7.0.1542.4e07369
dece9b6df7a13285a53877dc016f518a7657abbe9c03c861a34ec1472b7789b3
docker: Error response from daemon: network bridge not found.
root@sh-gpu102:~# docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
root@sh-gpu102:~#

重启大法

root@sh-gpu102:~# systemctl restart docker

不好使 ？

root@sh-gpu102:~# docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
root@sh-gpu102:~#

只能自定义网桥了

root@sh-gpu102:~# docker network create --driver bridge --subnet 172.200.0.0/16 --gateway 172.200.0.1 ai-bridge

创建容器

有一个缺点就是，必须指定网络模型，虽说 bridge 是 docker 的默认网络模型，但是自定义的显然没有取代 docker 默认的 bridge

root@sh-gpu102:~# docker run -it -d -v /mnt:/mnt -v /ssd:/ssd registry.test.cn/more/lite:2.7.0.1542.4e07369

至于为什么没有网络模型了，此问题没有找到根本原因，只能等待以后再查了
