Docker：重新附加到docker exec进程 [英] Docker: reattach to `docker exec` process

问题描述

如果我使用 docker exec 来启动外壳，

If I use docker exec to fire up a shell,

docker exec -ti <CONTAINER> /bin/bash

我可以使用Ctrl + p Ctrl + q分离此shell进程。然后此shell仍在容器内运行，但是我如何重新附加到该特定shell（由 docker exec 启动的外壳，而不是 docker run ）？

I could use Ctrl+p Ctrl+q to detach this shell process. Then this shell is still running inside the container, but how can I reattach to that one particular shell (the one started by docker exec, not docker run)?

推荐答案

可惜的是，这还不可能；请参阅此问题在GitHub上。我也想要此功能，但目前看来尚无直接方法。

Sadly, this is not possible yet; see this issue on GitHub. I've also wanted this functionality, but at the moment it seems like there's no direct way to do this.

已提出解决方案，以解决此问题您通过 ssh 访问一个框并在远程框中运行 docker exec 的位置（或者，对于您的终端仿真器不稳定，可能会导致您崩溃）：始终运行您的<$ c $在屏幕或 tmux 中使用c> docker exec 命令。这样，只要您脱离屏幕 / tmux 会话，就可以稍后重新连接到该会话，并且仍然您的 docker exec 命令可访问。 （这与建议由@ vodolaz095 有所不同，因为它涉及运行屏幕或 tmux 外部容器，所以它适合与不运行屏幕 / tmux 作为其主要过程的容器）

A workaround has been proposed, to take care of the case where you're accessing a box via ssh and running docker exec on the remote box (or, for the case where your terminal emulator is unstable and may crash on you): Always run your docker exec commands inside screen or tmux. If you do this, whenever you get detached from the screen/tmux session, you can re-attach to it later and still have your docker exec commands accessible. (this is a bit different than what was suggested by @vodolaz095, since it involves running screen or tmux outside the container, making it suitable for use with containers that don't run screen/tmux as their main process)
