Dockerfile Generator

Generate Dockerfiles for Node.js, Python, or Nginx static sites. A Dockerfile defines how to build a Docker image. Instead of writing from scratch, choose your stack, set options, and get a production-ready Dockerfile. Supports multi-stage builds for Node.js (Next.js, React, etc.) and single-stage for simple apps.

How to Generate a Dockerfile

Select app type: Node.js, Python, or Nginx static site.
For Node: choose version, package manager (npm/yarn/pnpm), and whether you have a build step.
For Python: choose version and whether you use requirements.txt.
Click "Generate" and copy the Dockerfile into your project root.

When to Use

Containerize a new app, deploy to Docker/Kubernetes, create consistent dev environments, or learn Docker best practices. The generated Dockerfiles use Alpine/slim images for smaller size and follow common patterns. All generation happens in your browser.
