How do i find what volume is being used for data?

Docker Desktop for Linux
1

I installed fireflyiii on a Raspberry Pi 4B (Raspian Lite). I want to make sure the data doesn’t get wiped out if the container needs to be deleted, but I first need to find the path for where it is currently being stored, how do I find that?

In the docker-compose.yml under volumes is this:

volumes:
      - firefly_iii_upload:/var/www/html/storage/upload

but the path /var/www/html/storage/upload does not exist, so I don’t know where to find the data directory.

firefly_iii_upload is a named docker volume, not a host path. As such its lifecycle is independent of the containers it is mapped to: it will be retained, regardless whether the container attached to it is deleted.

You can find either its location or the mount point of a remote share (that is, if it points to a remote share of course) using this command:

 docker volume inspect --format '{{.Mountpoint}}' firefly_iii_upload

Note: the folder you get as output is not mend to be directly accessed. If you change files from that location you might end up modifying ownership which might result in a problem when running you container.

Thank you for the reply.

When I run that command, I get this result,

docker volume inspect --format '{{.Mountpoint}}' firefly_iii_upload

Error response from daemon: get firefly_iii_upload: no such volume

You are right, I forget that the project name will be prefixed for volume created from within a compose file.
Please share the output of docker volume ls

try: docker volume inspect --format '{{.Mountpoint}}' fireflyiii_firefly_iii_upload

That worked:
