Why are multi-stage Docker builds recommended?

Multi-stage builds allow you to use large images containing compilers and SDKs during the build stage, then copy only the compiled binaries and production artifacts into a tiny runtime image (e.g. Alpine or distroless).

How does non-root user execution protect containers?

If a security vulnerability allows code execution inside the container, running as non-root prevents the attacker from gaining root access to the host kernel or mounted volumes.

Can I download the generated files directly?

Yes, you can click 'Download Dockerfile' or 'Download docker-compose.yml' to save ready-to-run files directly into your project root.
