复制码头码头容器进行调试 [英] Duplicating docker container for debugging

问题描述

我有一个运行的码头容器。我已经在运行的docker容器中做了一些有用的工作。我已经完成了这些工作，不是docker文件的一部分，我已经在容器内部完成了这个工作。例如：我已经在容器内部安装了ping，而不是从docker文件中安装）

我被困在一个地方。我不知道我是否在同一个容器中进行调试，我可能会放弃我在该容器内到目前为止所做的一切。

所以我想创建一个重复复制它与运行容器中可用的所有东西[像我不想从映像构建容器，并重复在运行容器中实现的所有有用步骤，然后启动我的调试。我不想在我的第二个容器中重新安装ping。]

总的来说，我如何复制容器？如果不是所有的可能性？

解决方案

1. 创建基本图像并运行

     docker run -it< base_image> / bin / bash 
     




2. 进行必要的更改

     yum install ping 
     




3. 提交它使用新名称

     docker commit<运行容器的哈希标签> new_image 
     

---

现在，如果您通过运行

  docker run -it new_image / bin / bash 
  

您可以在其中看到 ping 。

打开base_image，安装没有 ping

希望它回答你的问题。

I have a running docker container. I have done some useful works in the running docker container. I have done these works not part of dockerfile, i have done it inside the container.[Eg: I have installed ping inside the container, not from docker file]

Now, i got stuck at a place. I am not sure if i debug in the same container, i may loose the thing that i have done so far inside that container.

So i would like to create a duplicate copy of it with all the things available in that running container[like i don't want to build a container from image and repeat all the suucessful steps achieved in the running container and then start my debuggging. I don't want to re-install ping in my second container].

Totally, How can i duplicate a container? If not what are all the possibilities?

解决方案

1. Create a base image and run it

   docker run -it <base_image> /bin/bash
   

2. Make necessary changes

   yum install ping
   

3. Commit it with a new name

   docker commit <hash tag of running container> new_image
   

---

Now if you open new_image by running

docker run -it new_image /bin/bash

You can see ping is installed in it.

Open base_image and there is no ping installed in it.

Hope it answered your question.
