您可以将Docker映像转换/构建为完整的OS映像吗? [英] Can you convert/build a docker image into a full OS image?

问题描述

我已经制作了一个Docker容器，其中包含一些用于部署的代码.但是，我意识到我正在处理的项目的结构更适合部署完整的ISO映像，而不是在运行库存debian的云VM之上运行docker，从而导致不必要的虚拟化层.

I have made a docker container meant with some code for deployment. However, I realised that the structure of the project I'm working with, it's more suitable to deploy a full ISO image, instead of running docker on top of a cloud VM running stock debian, leading to unnecessary layers of virtualization.

我知道docker打算部署在kubernetes上，但是在深入探讨这条路线之前，是否有一种简单的方法可以将deb9 docker映像转换为完整的deb9 OS映像?像docker import的反义词一样?

I know that dockers are meant to be deployed on kubernetes, but before diving into that route, is there a simple way to convert a deb9 docker image into a full deb9 OS image? Like an opposite of docker import?

推荐答案

您可以将docker 容器转换为完整的OS映像. Dockerfile debian示例将是

You can convert your docker container to an full os image. An Dockerfile debian example would be

FROM debian:stretch
RUN apt-get -y install --no-install-recommends \
  linux-image-amd64 \
  systemd-sysv

原则上，您必须安装一个内核和一个初始化系统.

In principal you have to install a kernel and an init system.
