如何在“退出"之后保留泊坞码头高山容器?用来? [英] How to retain docker alpine container after "exit" is used?

问题描述

例如，如果我使用命令docker run -it alpine /bin/sh 它启动了一个终端，之后我可以安装软件包和所有软件包.现在，当我使用exit命令时，它会返回到终端. (主要一)

Like for example if I use command docker run -it alpine /bin/sh it starts a terminal after which I can install packages and all. Now when I use exit command it goes back to the terminal. (main one)

那么我该如何再次访问同一容器? 当我再次运行该命令时，我得到了一个新的阿尔卑斯山脉.

So how can I access the same container again? When I run that command again, I get a fresh alpine.

请帮助

推荐答案

只要指定的运行命令进程仍在运行，该容器就会存在.指定运行/bin/sh时，一旦退出，sh进程将终止，您的容器也将终止.

The container lives as long as the specified run command process is still running. When you specify to run /bin/sh, once you exit, the sh process will die and so will you container.

如果要保持容器运行，则必须保持进程内部运行.对于您的情况(我不确定您要达到的目标，我想您只是在测试)，以下内容将使其保持运行状态

If you want to keep your container running, you have to keep the process inside running. For your case (I am not sure what you want to acheive, I assume you are just testing), the following will keep it running

docker run -d --name alpine alpine tail -f /dev/null

然后您可以使用进入容器

Then you can sh into the container using

docker exec -it alpine sh
