Docker Run to Compose Converter

Docker Compose is a tool for defining and running multi-container Docker applications. You use a YAML file (docker-compose.yml) to configure your application's services, networks, and volumes, then run everything with a single command.

Docker run commands can get very long and complex. Converting them to docker-compose.yml makes them easier to read, version control, share with your team, and reproduce across environments.

This tool supports common flags including -d (detach), --name, -p (ports), -v (volumes), -e (environment variables), --env-file, --network, --restart, -w (working directory), --memory, --cpus, and --link.

The tool parses the docker run command string, extracts each flag and its arguments, then maps them to the equivalent docker-compose.yml fields. The image name becomes the 'image' field, and any trailing command becomes the 'command' field.

The output uses Docker Compose file version 3.8, which is compatible with Docker Engine 19.03+ and supports most modern features including deploy resource constraints.
