Docker Compose Converter converts docker run commands to Docker Compose YAML format and vice versa. Maintain consistent container configurations across development, staging, and production. Convert ad-hoc docker run commands from documentation into composable, version-controlled YAML service definitions with proper network, volume, and environment variable mappings.
How it Works
1Paste a docker run command or a Docker Compose YAML snippet into the input.
2Select the conversion direction: docker run → Compose, or Compose → docker run.
3The converter parses flags and generates the equivalent format.
4Copy the output and add it to your docker-compose.yml or shell script.
Frequently Asked Questions
Why should I use Docker Compose instead of docker run?
Docker Compose lets you define multi-container applications declaratively in a YAML file that can be version-controlled. It handles service dependencies (depends_on), shared networks, named volumes, and environment files. Running docker compose up brings up your entire stack. docker run is a one-off command; Compose is repeatable infrastructure.
Does the converter support Docker Compose v2 vs v3 syntax?
The converter targets Compose file format v3 (compatible with Docker Compose v1.27+ and Docker Desktop). The version key is included in the output. Key differences from v2: resources/limits are under deploy.resources, links are discouraged in favour of network-based service discovery.
Are volumes and bind mounts converted correctly?
Yes. The -v flag is converted to the volumes section with both short syntax (./host:./container) and long syntax (type, source, target) representations. Named volumes are added to the top-level volumes section.
Are environment variables from -e flags included?
Yes. Each -e KEY=VALUE flag becomes an entry in the environment section. The -env-file flag is converted to the env_file directive. Secret or sensitive values appear in the YAML as-is — replace with variable references before committing to source control.
