Similarly, what does docker compose do in detached mode?
In “detached” mode (-d), Compose exits after starting the containers, but the containers continue to run in the background. The docker-compose run command is for running “one-off” or “adhoc” tasks. It requires the service name you want to run and only starts containers for services that the running service depends on.
