Question 1

What is the difference between docker run and docker-compose?

Accepted Answer

docker run is a CLI command that starts a single container with options passed as flags (ports, volumes, environment variables, etc.). docker-compose (or docker compose) uses a YAML file to define and run multi-container applications. Compose makes it easy to version-control your container configuration, share it with teammates, and bring up entire stacks with a single command. For anything beyond a quick test, docker-compose is the recommended approach.

Question 2

How does the docker run to docker-compose conversion work?

Accepted Answer

The converter parses your docker run command and maps each flag to its equivalent docker-compose YAML key. For example, -p 8080:80 becomes ports: ['8080:80'], -e KEY=VALUE becomes environment variables, -v host:container becomes volumes, --name sets the service name, and --restart sets the restart policy. The output is a ready-to-use docker-compose.yml that you can save and run with docker compose up.

Question 3

What docker run flags are supported?

Accepted Answer

The converter supports the most common docker run flags: -p / --publish (port mappings), -e / --env (environment variables), -v / --volume (volume mounts), --name (container/service name), --restart (restart policy), -d / --detach (detached mode), --network (network), --hostname, --entrypoint, --user, -w / --workdir, --label, --memory, --cpus, and more. The image name and tag are also correctly extracted from the command.

Question 4

Can I convert multiple docker run commands at once?

Accepted Answer

This tool converts one docker run command at a time, producing a single-service docker-compose.yml. For multi-service setups, convert each docker run command separately and then manually merge the resulting services into one docker-compose.yml file. Alternatively, write the compose file by hand if you have complex inter-service dependencies such as depends_on, custom networks, or shared volumes.
