like just docker run by itself, it’s not the full command, you need a compose file: docs.docker.com/engine/reference/…/compose/

Basically it’s the same as docker run, but all the configuration is read from a file, not from stdin, more easily reproducible, you just have to store those files. The important is compose commands are very important for selfhosting, when your containers expected to run all the time.
