Dockerfiler

AI-powered Dockerfile generator using Groq API. Automatically generates optimized Dockerfiles based on your project's package.json.

Installation

npx dockerfiler

Or install globally:

npm install -g dockerfiler
dockerfiler

Usage

Navigate to your Node.js project directory (must contain package.json) and run:

npx dockerfiler

The tool will:

1. Analyze your package.json
2. Generate an optimized Dockerfile using AI
3. Create a .dockerignore file
4. Display the generated Dockerfile

Requirements

• Node.js 14 or higher
• A package.json file in your project

Features

• Zero external dependencies (uses only Node.js built-in modules)
• Generates production-ready Dockerfiles
• Supports various frameworks (Next.js, Express, React, etc.)
• Creates optimized .dockerignore files
• Uses Groq's Kimi AI model for intelligent Dockerfile generation

Example

cd my-nodejs-project
npx dockerfiler

Output:

Detected project: my-app
Analyzing project and generating Dockerfile...
Generated Dockerfile and .dockerignore

==================================================
Generated Dockerfile:
==================================================
FROM node:18-alpine
WORKDIR /app
COPY package*.json ./
RUN npm ci --production
COPY . .
EXPOSE 3000
CMD ["npm", "start"]
==================================================

Next steps:
  1. Review the Dockerfile
  2. Build: docker build -t myapp .
  3. Run: docker run -p 3000:3000 myapp

How It Works

Dockerfiler analyzes your package.json to detect:

• Project type (web app, API, CLI tool, etc.)
• Framework (Next.js, Express, NestJS, etc.)
• Dependencies and scripts

Then generates a Dockerfile with:

• Optimal base image (Alpine for smaller size)
• Multi-stage builds when beneficial
• Minimized layers for faster builds
• Security best practices (non-root user)
• Framework-specific optimizations
