How to organize docker volumes into subdirectories using compose - eviltoast

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?

    Thanks, this looks like it’ll do the job. I have not a lot of knowledge, so the specs are often a bit technical for me. I’ll give it a go, thanks!

      that is using bin mounts again. and i don’t get why this is discouraged, i actualy do like to know where my data is stored and don’t want to spin up a container that backs up using the volumes managed by docker. at that point you are using bind mounts again anyway.

      regarding your original question, i don’t think it is possible (or even useful) to tell docker where to store the volumes for each compose stack because you are not supposed to access the from the filesystem directly anyway.

      just continue using bind mounts
