“退出"后如何保留docker alpine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它启动一个终端，之后我可以安装软件包和所有内容.现在，当我使用 exit 命令时，它会返回到终端.(主要)

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)

那么我怎样才能再次访问同一个容器呢?当我再次运行该命令时，我得到了一个新的 alpine.

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

请帮忙

推荐答案

拉一张图片

docker image pull alpine

看到图片在那里

docker image ls   OR  just docker images

看看高山里面有什么

docker run alpine ls -al

现在你的问题是如何留在 shell 中

Now your question is how to stay with the shell

docker container run -it alpine /bin/sh

您在 shell 脚本命令行中.某些发行版可能有 bash shell.

You are inside shell script command line. Some distribution may have bash shell.

 docker exec -it 5f4 sh
 / # (<-- you can run linux command here!)

此时可以使用alpine的命令行做

At this point, you can use command line of alpine and do

ls -al

输入exit出来-您可以在分离模式下运行它，它会继续运行.

type exit to come out- You can run it in detached mode and it will keep running.

使用exec命令我们可以再次登录

With exec command we can login again

docker container run -it -d alpine /bin/sh

验证它是UP并复制容器ID的前2个-3位

verify that it is UP and copy the FIRST 2 -3 digits of the container ID

docker container ls

使用 exec 命令登录

login with exec command

docker exec -it <CONTAINER ID or just 2-3 digits> sh

您需要停止，否则它将继续运行.

You will need to STOP otherwise it will keep running.

docker stop <CONTAINER ID>
