Discussion on: Use Multi-Stage Docker Builds For Statically-Linked Rust Binaries

Appreciate this article so much. So many concepts being added to my knowledge-base for future use.

One thing I find is that I'm managing container-container communications a lot. Not a problem normally. How is that with scratch? Does Docker handle it all, or does the OS provide some abstraction that would need to be substituted within the binary?

EDIT: To be clear, I'm thinking of putting a binary at the end of an API call. If I could do that with a minimal image I would be so much happier. Just want to get the plumbing right 😉

I haven't tried yet, but my instinct tells me this is something Docker manages, not your containers. Like Moshe said, the Linux userland inside a container is explicitly for runtime needs of the container's internal commands, everything outside of that is handled by Docker itself.

Thanks. scratch feels like taking the training wheels off, but you have to do it at some point!

Afaik, scratch isn't "nothing", it just downloads nothing.
There's still stuff from the runtime when it's alive.
