Use the Docker Compose Validator to double-check the output, or the Docker Run to Compose Converter if you're migrating from existing docker run commands.

What Is Docker Compose?

Docker Compose defines and runs multi-container applications from a single YAML file - instead of running several docker run commands by hand, docker compose up starts every defined service together with the right ports, volumes, and networking.

Why Use This Tool?

Assembling a correct docker-compose.yml by hand means remembering the right image names, environment variables, and port mappings for each common service (a Postgres database, Redis cache, and so on). This tool provides working starting definitions for the most common combinations.

How to Use It

Enable the services you need: application, database (MySQL/Postgres), Redis, and/or a web server.
Configure ports, volumes, and environment variables for each enabled service.
Copy the generated docker-compose.yml into your project.

Limitations

This is not a claim of full Docker Compose spec compatibility - it covers the common fields (services, ports, volumes, environment, networks, depends_on) most local development setups need, not every advanced Compose feature.

Frequently Asked Questions

Save the file as docker-compose.yml (or compose.yaml) and run docker compose up -d in the same folder. Use docker compose down to stop them.

Compose puts all services on a shared network where each service name is its hostname. Your app can reach a database service named "db" at db:5432, for example.

Use a named volume for the database data directory. Data in a volume survives docker compose down, unless you add the -v flag.
