要从正在运行的容器中分离，请使用^P^Q(按住Ctrl，按P，按Q，释放Ctrl)。

这里有一个问题:这只在容器同时以-t和-i开始时才有效。

如果你有一个正在运行的容器，启动时没有这些选项中的一个(或两个)，并且你使用docker attach附加，你需要找到另一种方法来分离。^C可以工作，也可以杀死整个容器，这取决于你选择的选项和正在运行的程序。你得自己试验一下。

Another catch: Depending on the programs you're using, your terminal, shell, SSH client, or multiplexer could be intercepting either ^P or ^Q (usually the latter). To test whether this is the issue, try running or attaching with the --detach-keys z argument. You should now be able to detach by pressing z, without any modifiers. If this works, another program is interfering. The easiest way to work around this is to set your own detach sequence using the --detach-keys argument. (For example, to exit with ^K, use --detach-keys 'ctrl-k'.) Alternatively, you can attempt to disable interception of the keys in your terminal or other interfering program. For example, stty start '' or stty start undef may prevent the terminal from intercepting ^Q on some POSIX systems, though I haven't found this to be helpful.

我用的是Mac电脑，出于某种原因，Ctrl-p Ctrl-q只有在按住Shift的时候才会起作用

打开一个新终端 找到正在运行的容器Id docker ps 删除容器的docker

还可以查看——sig-proxy选项:

docker attach --sig-proxy=false 304f5db405ec

然后使用Ctrl+C分离

要从容器中分离，只需按住Ctrl并按P + Q。

附加到你使用的正在运行的容器:

$ docker container attach "container_name"
