如何附加到以分离模式运行的Docker容器？ [英] How can I attach to docker container running in detached mode?

问题描述

如果我使用以下命令以分离模式启动Docker容器：

If I start up a docker container in detached mode using the command:

docker run -d ubuntu

容器立即退出。 docker ps -a 产生输出（显示选定的列）：

the container immediately exits. docker ps -a yields the output (selected columns shown):

CONTAINER ID        IMAGE               COMMAND             STATUS
245fe871a1e3        ubuntu              "/bin/bash"         Exited (0) 4 minutes ago

是否可以在终端会话的交互模式下启动同一容器（容器ID 245fe871a1e3 ）？

Is it possible to start the same container (container ID 245fe871a1e3) in interactive mode with a terminal session?

推荐答案

恐怕没有这样一种存档方法。 docker attach 和 docker exec 仅适用于运行容器，但是如果您 docker start 您所用的容器，由于 CMD 为 / bin / bash 。

I'm afraid there's no such a way to archive this. docker attach and docker exec are working against running container only, but if you docker start the container in your case, it'll exited immediately again because the CMD is /bin/bash.

还有讨论关于此信息，请在此处发布一些关键信息：

There's also a discussion about this, post some key info here:

不可能输入已停止的容器，因为进程已消失，因此，名称空间也消失了。

It's not possible to enter a stopped container, because the processes are gone, and therefore, the namespaces are gone as well.
