Until someone overwrites or deletes the Docker base image (regularly happens), or when you depend on some packages installed through apt - as you'll get the latest version (impossible to pin those).

I am convinced that any sort of free public service is fundamentally incomapatible with long term reproducible builds. It is simply unfair to expect free service to maintain archives forever and never clean them up, rename itself, or go out of business.

If you want reproducibility, the first step is to copy everything to a storage you control. Luckily, this is pretty cheap nowdays

Any source of that claim?

Well... please re-read my previous comment - we do Java thing so we use any JDK base image and then we slap our distribution on top of it (which are mostly fixed-version jars).

Of course if you are after perfection and require additional packages then you can install it via dpgk or somesuch but... do you really need that? What about security implications?

Any tag like ubuntu:20.04 -> this tag gets overwritten every time there's a new release (which is very often)

https://hub.docker.com/r/nvidia/cuda -> these get removed (see e.g. https://stackoverflow.com/questions/73513439/on-what-conditi...)
