我们是否应该一开始就从Docker Hub安装Docker映像？

Question

I want to introduce docker for my development environment.

I wanted to create a docker image from a existing linux machine. But,I could not find a official method on docker documentation. https://docs.docker.com/learn/ (I know there are some ways on the Internet to create a docker image like converting .iso file to .tar.gz file. However,it's not official)

After that,I installed a docker image of Debian OS from Docker Hub with 'docker pull' command. However,I could not find a correct version of Debian OS I wanted.

So, to get a OS of a correct kernel verion and a correct Debian os version, after I install a docker image from Docker Hub, should I customize it? Is there any way as an official manner to create a docker image from a exisiting linux machine?

Sounds like you should be looking at Hashicorp's packer, it would allow you to build your own Docker base images, from whatever base you wish.
