Rust Docker Pipeline — cargo-chef

Build and ship Rust in Docker fast, with cargo-chef layer caching.

A focused lesson in fast, cache-friendly Rust container builds, around a tiny axum app. cargo-chef caches the dependency layer so a code change doesn't recompile the world, and an export stage writes the binary out so a server too small to compile Rust can run a prebuilt one. Two compose files show both paths.

What's inside

• cargo-chef dependency-layer caching
• From-source and precompiled build paths
• Multi-stage Dockerfile with a binary export stage
• A compose file per variant
• Distroless, non-root final image

Quickstart
