How to build a Docker base image from scratch

Question

Currently I use:

docker pull microsoft/windowsservercore

to pull a base image. But I want to make my own base image. How can I do that?

Answer 1

There are many ways to build a base image. You can use tar or scratch

Refer the example below or look up docker’s official website, you might find something there.

FROM scratch
ADD helloworld.sh /usr/local/bin/hellowworld.sh
CMD ["/usr/local/bin/helloworld.sh"]
