Docker守护程序重新启动并重新附加到容器 [英] Docker daemon restart and reattaching to containers

问题描述

如果我杀死了docker daemon进程然后重新启动它，则正在运行的所有容器现在都以 Exited 状态列出，并且无法使用docker-compose重新启动，因为它会抱怨容器名称已经存在

If I kill my docker daemon process and then restart it, any containers that were running are now listed with Exited status and cannot be restarted using docker-compose as it will complain about the container name already being in use.

可以使用docker start重新启动Docker容器，但是当您有很多容器时，这可能很难。

Docker containers can be started again using docker start but this could be hard when you've many containers.

有什么方法可以重启docker守护进程，保持容器运行（以免干扰流量）并使守护进程重新连接到容器上吗？

Is there any way to restart the docker daemon, leave containers running (so as to not disrupt traffic) and have the daemon reattach to the containers?
