Switched from Debian to Alpine Linux for significant improvements: - Image size: ~5MB vs ~100MB (95% smaller) - Security: Minimal attack surface, no glibc vulnerabilities - Static linking: No glibc version issues ever again - Uses rust:alpine builder with x86_64-unknown-linux-musl target - Static binaries with RUSTFLAGS='-C target-feature=+crt-static' Fixes the GLIBC_2.38 error permanently by avoiding glibc entirely.
