Dockerfile Generator
Generate a practical Dockerfile for Node, static Nginx, or Python projects with optional multi-stage builds.
Build a Dockerfile starter for common deployment scenarios without writing the same base image, workdir, copy, and command sections from scratch.

Create a fast starter Dockerfile for app repos that do not yet have containerization.
Standardize common Dockerfile patterns for frontend, backend, and small Python services.
FAQ
Does this optimize for every language ecosystem?
No. It focuses on common Node, static Nginx, and simple Python deployment paths.
Should I still review the generated Dockerfile?
Yes. You should still adjust caching, lockfiles, secrets, and runtime hardening for your project.
