Dockerfile & docker-compose Generator
Pick your stack and port to generate a production-ready, multi-stage Dockerfile plus a matching docker-compose.yml.
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.
