Docker - 使用新的TTY输入运行容器 [英] Docker - Enter Running Container with new TTY

问题描述

我有一个在前台运行Apache服务的容器。我希望能够从另一个shell访问容器，以便在其中戳并检查文件。目前，如果我附加到容器，我看着Apache守护程序，不能运行任何命令。

是否可以将另一个tty附加到正在运行的容器？可能的是，我可以利用Docker实际上只是围绕LXC容器的事实吗？我试过 sudo lxc-console -n [container-id] -t [1-4] ，但似乎只有一个tty可用，那就是一个运行apache守护进程。也许有一种方法可以在构建期间启用多个lxc控制台？

我宁愿不使用openssh服务配置和构建容器，如果

解决方案

使用docker 1.3，有一个新的命令 docker exec 。这可以让您进入正在运行的码头服务器：

  docker exec -it [container-id] bash 
  

I have a container that is running the Apache service in the foreground. I would like to be able to access the container from another shell in order to "poke around" inside it and examine the files. At the moment, if I attach to the container, I am left looking at the Apache daemon and cannot run any commands.

Is it possible to attach another tty to a running container? Possibly, I can take advantage of the fact that Docker is actually just wrapping around LXC containers? I have tried sudo lxc-console -n [container-id] -t [1-4] but it appears that only one tty is made available and that is the one running the apache daemon. Perhaps there is a way to enable multiple lxc consoles during the build?

I would rather not configure and build the container with an openssh service if possible.

解决方案

With docker 1.3, there is a new command docker exec. This allows you to enter a running docker:

docker exec -it [container-id] bash
