如何为 Docker 制作自己的基础镜像? [英] How can I make my own base image for Docker?

问题描述

根据 Docker 文档，要构建自己的镜像，您必须始终使用 FROM 指令指定基本图像.

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

显然，Docker 索引中有很多图像可供选择，但如果我想怎么办建立我自己的?这可能吗?

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?

如果我理解正确的话，图像 base 是基于 Ubuntu 构建的，我想用 Debian 图像进行试验.另外，我想真正了解 Docker 的工作原理，而 base 镜像对我来说仍然是一个黑盒.

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.

关于创建基础镜像的官方文档

推荐答案

您可以查看基本图像的创建方式并从那里开始.

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

您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
