modbender 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

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.
