Examples

Example docker-compose.yml

Generate a FastAPI service with PostgreSQL, Redis, named volumes, healthchecks, and local ports.

How it works

  1. What this Docker Compose builder does: selects a known web stack and emits docker-compose.yml, .env.example, commands, connection strings, notes, and warnings.
  2. Supported stacks: FastAPI, Django Celery, Node.js, Next.js, Laravel, WordPress, Airflow, and local AI app presets are generated from deterministic templates.
  3. Development vs production notes: development mode favors bind mounts and local service ports; production mode adds restart policies but remains a starting point, not hardened infrastructure.
  4. Common Docker Compose mistakes: hard-coded secrets, missing healthchecks, accidental database exposure, and unclear volume choices are called out in the generated output.

Limitations

  • The tool generates stack-specific boilerplate, not a complete production deployment platform.
  • Image tags, app commands, mounted paths, and Nginx config paths should be reviewed for your actual repository.
  • Secrets are represented as placeholder environment variables and must be replaced before real use.

FAQ

Does this Docker Compose builder upload my stack settings?

No. Preset selection, option handling, and file generation all run locally in your browser.

Is the production mode ready for production?

No. It adds starter restart policies and safer defaults, but you still need secret management, TLS, backups, resource limits, monitoring, and deployment-specific hardening.

Can I use the generated YAML directly?

Yes for common local starts, but you should adjust image names, build contexts, commands, ports, and mounted paths to match your application.
