Docker Compose Generator

Docker Compose is a tool for defining and running multi-container applications from a single YAML file. You declare services, networks, and volumes once and manage the whole application with commands like docker compose up and docker compose down.

No. Modern Docker Compose (the Compose Specification) does not need a top-level version field, and this generator does not add one. The optional name field sets the project name.

Add one or more services in the builder, set each service’s image (or build), ports, volumes, networks, environment variables, and health check, then copy or download the generated compose.yaml. The YAML updates in real time as you edit.

They are the same format. compose.yaml is the modern, preferred filename; docker-compose.yml is the older name and still fully supported. You can choose either filename in the generator.

The generator validates your configuration in the browser as you build — checking service names, ports, durations, memory units, dependency cycles, and network CIDRs — and runs a security scan. You can also run docker compose -f compose.yaml config locally to validate with the Docker CLI.

Yes. Each service in the Compose file runs as one or more containers, and Compose creates a shared network so they can reach each other by service name.

Compose creates a default network where services resolve each other by name via Docker’s embedded DNS. You can add custom bridge networks (including internal, non-routable ones) to segment tiers — for example keeping a database off the public-facing network.

Named volumes are Docker-managed persistent storage that survive container recreation; bind mounts map a host path into the container. The generator auto-declares any named volume your services use at the bottom of the file.

Never hard-code secrets in the file. Reference them as ${VARIABLE} from an untracked .env, or use Docker Compose secrets. The generator detects likely secrets and offers to convert them to references, and can generate a .env.example and .gitignore.

Yes. Paste or upload a Compose file and the generator imports the supported fields into the visual builder and reports anything it could not map, so nothing is silently lost. Imported YAML is parsed safely and never executed.

Yes. Building, validating, copying, downloading, importing, and all templates are free. It also runs entirely in your browser — nothing is uploaded.

No. The generator only produces and validates YAML. It never builds images, runs containers, or executes any uploaded file.
