Docker → Compose is a free online api tool that convert docker run commands to docker-compose.yml format instantly. It works entirely in your browser — no downloads, no installations, and no server uploads required. backend developers, QA engineers, integration specialists use Docker → Compose when they need a fast, privacy-respecting way to process api data without installing additional software. It supports capabilities such as flag mapping, real-time conversion, syntax validation. Additional features include privacy first. Common use cases include migrating docker run based development setups to docker-compose.yml, converting one-off docker run commands from documentation to reusable compose files, standardizing local development environments with version-controlled compose files. All processing happens locally using modern browser APIs, which means your data never leaves your device. This makes Docker → Compose ideal for working with sensitive data, proprietary code, or any situation where privacy matters.
Docker Run to Compose Converter is a free online api tool that helps you convert docker run commands to docker-compose.yml format instantly. Key capabilities include flag mapping, real-time conversion, syntax validation. All processing is done locally in your browser — no data is uploaded, stored, or shared with any server. There are no sign-ups, no file size limits, and no hidden charges. It is commonly used to migrating docker run based development setups to docker-compose.yml.
Copy your docker run CLI command and paste it into the input area above.
The docker-compose.yml output updates in real-time as you type. Ports, volumes, environment variables, and all flags are mapped to compose format.
Click Copy to grab the compose YAML, or download it as a .yml file for use in your project.

All operations run entirely in your browser using built-in API APIs. No server uploads, no data storage, and no third-party requests.
Docker → Compose is ideal when you need to migrating docker run based development setups to docker-compose.yml without installing software or uploading data to a server. Since everything runs in your browser, there is no setup time and no risk of your data being stored on external servers. For for collaborative API development and testing, consider using Postman. For for lightweight REST and GraphQL debugging, Insomnia may be a better fit. Docker → Compose fills the gap between heavyweight desktop tools and insecure online services that require uploading your data.
No. Docker → Compose processes everything entirely in your browser using JavaScript. Nothing you type, paste, or upload is ever transmitted to any server. Your data never leaves your device.
It supports all commonly used flags including -p, -v, -e, --name, --restart, --network, -d, -it, --rm, --memory, --cpus, --env-file, -w, -u, --entrypoint, --label, --expose, --add-host, --platform, --health-cmd, and more.
Docker run -p 8080:80 becomes ports: ['8080:80'] in compose. Multiple -p flags produce multiple port entries.
Maps all common docker run flags to compose equivalents: ports (-p), volumes (-v), env (-e), networks, restart policies, healthchecks, and more.
See the compose YAML update live as you edit the docker run command — no button clicking needed.
Invalid docker run commands are flagged with clear error messages so you can fix and retry.
All parsing happens locally in your browser. Your docker commands never leave your device.
Docker Run to Compose Converter is useful in a variety of scenarios across different workflows:
Migrating docker run based development setups to docker-compose.yml
Converting one-off docker run commands from documentation to reusable compose files
Standardizing local development environments with version-controlled compose files
The --name flag becomes the service name in compose. Without it, the service name is derived from the image name. Always use --name for clarity.
The --restart flag maps to the restart policy in compose. 'unless-stopped', 'always', 'on-failure', and 'no' are all supported.
