Dockerize

Automatically generate Dockerfiles by analyzing your codebase. This npm package detects your project type and generates an appropriate Dockerfile for you.

Installation

npm install

Usage

Local Development

After installing dependencies, you can run:

npm link
dockerize

As npx Package

Once published to npm, you can use it directly with:

npx dockerize

Features

• 🔍 Automatic Detection: Analyzes your codebase to detect project type
• 🐳 Smart Dockerfiles: Generates optimized Dockerfiles for various frameworks
• 📦 Multi-language Support: Supports Node.js, Python, Java, Go, Rust, Ruby, PHP, and more
• ⚙️ Framework-aware: Detects specific frameworks like React, Next.js, Django, Flask, FastAPI, etc.

Supported Project Types

Node.js

• React/Vite: Multi-stage build with nginx
• Next.js: Optimized Next.js production build
• Backend: Express, Fastify, Koa, etc.
• Generic Node.js: Standard Node.js applications

Python

• Django: Includes migrations and static files
• Flask: Uses Gunicorn for production
• FastAPI: Uses Uvicorn server
• Generic Python: Standard Python applications

Java

• Maven: Multi-stage build with Maven
• Gradle: Multi-stage build with Gradle

Other Languages

• Go: Multi-stage build with Go
• Rust: Multi-stage build with Cargo
• Ruby: Rails applications
• PHP: Apache with Composer

Options

dockerize [options]

Options:
  -V, --version          Show version number
  -o, --output <file>    Output Dockerfile path (default: "Dockerfile")
  -f, --force            Overwrite existing Dockerfile
  -h, --help             Display help for command

Examples

Generate a Dockerfile in the current directory:

dockerize

Generate a Dockerfile with a custom name:

dockerize -o Dockerfile.prod

Overwrite an existing Dockerfile:

dockerize --force

How It Works

1. Analysis: Scans your project directory for configuration files (package.json, requirements.txt, pom.xml, etc.)
2. Detection: Identifies the project type and framework based on detected files
3. Generation: Creates an optimized Dockerfile template for your specific project type

Publishing to npm

To publish this package to npm:

npm login
npm publish

After publishing, users can install and use it globally or via npx:

npx dockerize
