如何为Docker制作自己的基本图像？ [英] How can I make my own base image for Docker?

问题描述

根据 Docker文档，为了构建您自己的图像，您必须始终指定基数图像使用 FROM 指令。

According to the Docker documentation, to build your own image, you must always specify a base image using the FROM instruction.

显然，在 Docker索引，但如果我想建立自己的索引呢？这是可能的吗？

Obviously, there are lots of images to choose from in the Docker index, but what if I wanted to build my own? Is that possible?

如果我理解正确，图像 base 是由Ubuntu构建的，我想试验一个Debian镜像。另外，我想真正了解Docker的工作原理，而 base image对我而言仍然是一个黑盒子。

The image base is built off Ubuntu if I understand correctly, and I want to experiment with a Debian image. Plus, I want to really understand how Docker works, and the base image is still a blackbox for me.

推荐答案

你可以看看基础图像是如何创建的，从那里去。

You can take a look at how the base images are created and go from there.

你可以在这里找到它们： https://github.com/dotcloud/docker/tree/master/contrib 。
有mkimage-busybox.sh，mkimage-unittest.sh，mkimage-debian.sh
