Why multi-stage builds?

Multi-stage Dockerfiles use one stage to install dependencies and compile/build, then copy only the final artifacts into a slim runtime image. This keeps production images small and avoids shipping build tools, dev dependencies, and source maps you don't need at runtime.

Frequently Asked Questions

Do I need to change anything before using this Dockerfile?

Check the entrypoint command matches your actual start script/binary name, and adjust the exposed port if your app doesn't read it from the PORT environment variable.

Why is there a non-root user in some templates?

Running containers as a non-root user is a security best practice — it limits the blast radius if the container is ever compromised. Not all base images make this trivial, so it's included where practical.
