How to organize docker volumes into subdirectories using compose (feddit.de)

Hei there. I've read that it's best practice to use docker volumes to store persistent container data (such as config, files) instead of using bindmount. So far, I've only used the latter and would like to change this.

From what I've read, all volumes are stored in var/lib/docker/volumes. I also understood, that a volume is basically a subdirectory in that path.

I'd like to keep things organized and would like the volumes of my containers to be stored in subdirectories for each stack in docker compose, e.g.

volumes/arr/qbit /arr/gluetun /nextcloud/nextcloud /nextcloud/database

Is this possible using compose?

Another noob question: is there any disadvantage to using the default network docker creates for each stack/container?

Yeah, that seems to be the gist of it. I've seen several people say that they prefer volumes as they are managed by docker and therefore easier to migrate / backup. Since I plan on moving to different hardware in the near future, I figured why not.

Also something about permissions, though I never had any problems with it. So as you said, I'm sticking with bind mounts for now.

Also I don't have a clue what I'm doing at least 50 percent of the time and just follow guides. That's why I wanted some clarification on that :)
