Add your services
Start by adding services to your composition. Choose from popular templates (PostgreSQL, Redis, Nginx, Node.js) or create custom services. Each service maps to a container in your Docker setup.
Configure ports and volumes
Map host ports to container ports (e.g., 8080:80) and define volume mounts for persistent data. The visual interface prevents common mistakes like port conflicts and invalid mount paths.
Set environment variables
Add environment variables for each service — database passwords, API keys, configuration flags. The tool provides sensible defaults for popular images and warns about missing required variables.
Export the YAML
Copy the generated docker-compose.yml or download it directly. The output follows the Compose v3 specification and is ready to run with docker compose up. No manual YAML editing needed.
