Create Ubuntu ISO identical to Docker Hub image of Ubuntu

I developed a program working inside a docker container to be independent of my personal devices' libraries. Now I would like to setup a real computer from scratch to use it to run my program (and know that it is the identical environment in which I developed).

In my Dockerfile that I used I run:

From ubuntu:focal-20220404

I see that on Docker Hub Canonical's rootfs tarballs are referenced. They also include a *.manifest file which (if I understand correctly) describes all installed packages (including which version). But how to proceed with this knowledge?

Following Ubuntu's installation tutorial I am forwarded to download the 20.04 Ubuntu image but there is no choice for different versions as are published on Docker Hub. Is there a way to achieve what I want?

Thanks a lot in advance!
