Availability/Reproducibility of Ubuntu Minimal as Docker image While for Debian you find on Docker Hub "slim" distributions, it seems not the case with Ubuntu.

Now there is a "minimal Ubuntu for public clouds" distro from Canonical, but I can find just cloud VM images; is there a Dockerfile for that, as well?
The answer to the question "is there a Dockerfile for that, as well?"

Note their git branches contain the actual release build based on architecture.
