Another suggestion here is to use one of the debian slim images as base, like debian:bookworm-slim. Should have a much smaller image size

@mempirate I'll test but can't we also use reqwest with native rust-tls and then use a scratch image with statically compiled binaries?

I haven't checked the whole codebase but something like this:

reqwest = { version = "0.12.5", default-features = false, features = [
  "rustls-tls",
  "json",
] }

Should work.

I don't have a lot of experience with scratch images but that could be another option! There are other dependencies like libssl-dev and libssl3 (which include stuff like libcrypto etc) though.

Yes, I tried to statically compile with target musl and gnu and changing reqwest feature set to use rusttls-tls, it is almost impossible to get something coherent and it fails due to proc-macros (I somehow managed to build a statically compiled binary on archlinux which had both glibc and musl installed :P but I couldn't reproduced the behavior with docker images and cargo chef)

I think keeping the binary dynamically linked using debian is the easiest route for now
