Docker Run to Compose Converter

Sample commands

docker run command

Compose version

Service name

docker-compose.yml

What is Docker Compose?

Docker Compose is a tool for defining and running multi-container Docker applications using a YAML configuration file. It's easier to maintain and version-control than long docker run commands.

Supported flags

This converter supports the most common docker run flags: -p (ports), -v (volumes), -e (environment), --network, --restart, --hostname, -m (memory), --cpus, --label and more.

Privacy first

Your docker commands are processed entirely in the browser. Nothing is sent to a server — ideal for commands that may contain sensitive environment variables.

Frequently asked questions about Docker Compose

Everything about converting docker run to docker-compose.yml

Docker Compose is a tool that lets you define your application's services, networks, and volumes in a single YAML file (docker-compose.yml). It's far easier to read, maintain, and version-control than long docker run commands. You can start all services with a single "docker compose up" command.

Use docker run for quick one-off containers or testing. Use docker-compose.yml for any setup you want to persist, share with teammates, or run repeatedly. It also makes multi-container setups (e.g. app + database + cache) much simpler to manage.

Volumes in Docker Compose can be bind mounts (host path:container path) or named volumes. Named volumes are managed by Docker and persist across container restarts. In this converter, -v flags from your docker run command are mapped directly to the volumes: section of the compose file.

Environment variables set with -e KEY=VALUE in docker run become entries under the environment: key in docker-compose.yml. You can also reference an env_file (from --env-file) for larger sets of variables. Never commit secrets directly — use a .env file and reference variables with ${VARIABLE_NAME} syntax.

Convert docker run to docker-compose

The docker run to compose converter turns a long docker run command into a tidy docker-compose.yml. Options such as ports, volumes, environment variables and networks become the matching YAML keys. That saves you from looking up the Compose syntax and turns a hard-to-maintain one-liner into a versionable, reusable file. The conversion runs entirely in the browser.

Common use cases

Make containers permanent: Move a container you started ad hoc into a reproducible Compose file for your project.
Document commands: Record how a container was started instead of searching a long command in your shell history.
Share setups: Give colleagues a clear docker-compose.yml instead of an error-prone one-liner.
Learn the Compose syntax: See from your own example how run options map to the keys in the YAML.

How to convert your command

1 Paste your full docker run command into the input field.
2 The tool parses the options and generates the corresponding docker-compose.yml.
3 Review the generated YAML and adjust service names if needed.
4 Copy the file or download it.

From one-liner to maintainable file

Long docker run commands are hard to read, version and share. A docker-compose.yml makes the same configuration explicit, easy to comment and startable with a single command. The converter handles translating the options for you; still, review the result, especially for rarely used flags. Because everything happens locally, no environment variables or credentials from your command ever reach a server.
