Definitely don’t put everything in a single docker-compose file. For one compose files change from the developer to add/adjust things. You want to make updating to the latest one as easy as copying it over the existing one with minor changes if any, ideally none. For another, you shouldn’t rely on running any of it manually. If you want to chuck it in a corner, write some systems unit files to start and restart the docker compose services for you. Finally, it’s not too difficult to find what compose files you have once you’ve forgotten them. Use docker compose ls, plain docker and if all else fails find, grep.
