Rust applications can result in small and fast static binaries. See how to create optimized Docker images.

Multi-Stage Builds

Use multi-stage builds to separate compilation from runtime. The result is minimal production images.

Dockerfile Example

# Build stage FROM rust:1.75 as builder WORKDIR /app COPY . . RUN cargo build --release # Runtime stage FROM debian:bookworm-slim COPY --from=builder /app/target/release/myapp /usr/local/bin/ CMD ["myapp"]

Optimization Tips

• Use minimal base images (debian-slim, alpine)
• Compile with --release for optimizations
• Remove debug symbols in production
• Use .dockerignore to exclude unnecessary files

Conclusion

Optimized images result in faster deployment and smaller attack surface.
