for long-running services, I've never taken the time to learn something reliable like systemd. with Compose, I can see everything I need to know in one yml file and the commands to go with it. I also don't have to really understand any dependencies or their own configuration and can cleanly remove everything associated with that service with a few commands.

You can use systemd and docker compose together. A systemd service is a single config file that runs the commands you give it, including `docker-compose` commands. Everything else about your service is still orchestrated via docker, and you can still run commands against the running containers just like before.

A big win with very little effort is systemd starting your docker compose service on boot. You have your systemd config file set `ExecStart` to call your docker-compose command, throw the config file into your systemd folder, and tell systemd to enable it. Docker compose handles the rest.
