Question 1

How do I adapt mini-docker-rust for my own Rust project?

Accepted Answer

Start by copying the annotated Dockerfile and modifying the cargo commands and dependencies for your project's structure; ensure compatibility with Alpine's musl libc if using external crates.

Question 2

mini-docker-rust vs johnthagen/min-sized-rust: which should I use?

Accepted Answer

mini-docker-rust focuses on minimal Docker images with Alpine, while johnthagen/min-sized-rust optimizes Rust binary size itself; use both together for the smallest possible containers, as referenced in the README.

Question 3

Why choose Alpine over other bases like Debian for Rust Docker?

Accepted Answer

Alpine offers smaller image sizes (e.g., 5-8MB here) due to musl libc, but may require extra steps for glibc compatibility; it's a trade-off between size and ease of dependency management.

Question 4

What size differences exist between Alpine versions in mini-docker-rust?

Accepted Answer

The README shows historical sizes, such as 5.69MB for Alpine 3.16 vs 8.22MB for 3.19, highlighting that newer versions may be larger but more secure; always balance size with support.

Question 5

Is mini-docker-rust production-ready or just for learning?

Accepted Answer

It's primarily an educational example, but the techniques are practical for production if adapted correctly; however, you'll need to add monitoring, logging, and security hardening based on your needs.

Question 6

How to handle updates when Alpine or Rust versions change?

Accepted Answer

Monitor the GitHub repo for changes, as it tracks versions; manually update the Dockerfile base image and Rust toolchain, testing for compatibility with your dependencies each time.
