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
9029d91739e65fde98bf737e615ec484410370c74ee7582ed6727c7dad4517dd
root@sh-gpu102:~# docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
9029d91739e6        ai-bridge        bridge              local

创建容器

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

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
dd6d3102d1156253dcb6221087dd3799efaeff9b46873d19fb6b1eeda17b93e0
docker: Error response from daemon: network bridge not found.
root@sh-gpu102:~#

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

总结

以上为个人经验,希望能给大家一个参考,也希望大家多多支持。
