description Generate docker-compose.yml by scanning your project. Use when containerizing an existing app.

Compose Gen

Writing docker-compose from scratch is tedious. This tool scans your project, detects services, and generates a working docker-compose.yml. Database, cache, your app, all wired up correctly.

One command. Zero config. Just works.

Quick Start

npx ai-docker-compose

What It Does

  • Scans your project to detect services needed
  • Generates docker-compose.yml with proper networking
  • Includes database, cache, and queue services as needed
  • Sets up volumes for persistence
  • Adds health checks and depends_on

Usage Examples

# Generate for current project
npx ai-docker-compose

# Specify services manually
npx ai-docker-compose --services postgres,redis,app

# Include development overrides
npx ai-docker-compose --with-dev

# Output to specific file
npx ai-docker-compose > docker-compose.yml

Best Practices

  • Use named volumes - Don't lose your data on container restart
  • Add health checks - Make depends_on actually wait for services
  • Separate dev and prod - Use docker-compose.override.yml for dev settings
  • Pin image versions - postgres:latest will break eventually

When to Use This

  • Containerizing an existing application
  • Don't remember the docker-compose syntax
  • Need a quick local development environment
  • Setting up a new service and need the boilerplate

Requirements

No install needed. Just run with npx. Node.js 18+ recommended. Requires OPENAI_API_KEY environment variable.

export OPENAI_API_KEY=sk-...
npx ai-docker-compose --help

How It Works

Scans package.json, requirements.txt, or other config files to detect your stack. Identifies database connections, cache usage, and external service dependencies. Generates docker-compose.yml with appropriate services, networks, and volumes.
