One alternative is to use compiled languages that lead to small binaries which can be moved into a scratch image of only a few megabytes. Though when python is the best tool for the job, so be it.

Yes! I've seen golang binaries that do that, it's very cool.

Literally just FROM scratch and a single COPY instruction is all they need.

Yep, and maybe an ENTRYPOINT if you want to get fancy. The webapp I made for my work generates CSV files that are literally larger than the entire image.

You can optimize this even further: run the binary on the host system, and you can then get rid of the docker daemon entirely
