Where is persistant directory for docker installed ownCloud service

Actually I'm not in trouble but I'm just curious.
I'm running ownCloud server with docker, and I found out that even if I remove container by
docker-compose down
when I run ownCloud again, it still has all the data, configurations, and users. My first thought was that there should be some mounted volume so I looked on docker-compose.yml and still I can't find mounted volume.

For example, I can see this on docker-compose.yml,
- files:/mnt/data

But there is no /files nor /mnt/data directory on my machine.

Everything is fine for now, but since I am responsible for this server, I need to know where ownCloud stores whole data and configurations.

Thanks for reading.

Actual behaviour

Server configuration

Operating system: Mac OS High Sierra

Web server: httpd

Database: Maria db

PHP version: 7.1

ownCloud version: (see ownCloud admin page)

Updated from an older ownCloud or fresh install: fresh install

Where did you install ownCloud from: on Desktop/owncloud_docker/, docker-compose up -d

Signing status (ownCloud 9.0 and above):

Login as admin user into your ownCloud and access 
paste the results into https://gist.github.com/ and puth the link here.

The content of config/config.php:

Log in to the web-UI with an administrator account and click on
'admin' -> 'Generate Config Report' -> 'Download ownCloud config report'
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.


If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your ownCloud installation folder

*ATTENTION:* Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove *all* host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.

List of activated apps:

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your ownCloud installation folder.

Are you using external storage, if yes which one: local/smb/sftp/...

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...

LDAP configuration (delete this part if not used)

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';

Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

Client configuration


Operating system:


Web server error log

Insert your webserver log here

ownCloud log (data/owncloud.log)

Insert your ownCloud log here

Browser log

Insert your browser log here, this could for example include:

a) The javascript console log
b) The network log 
c) ...

This looks to me more like a docker related question then something specific to ownCloud. From what i know you can show all volumes with the following command:

docker volume ls

and inspect that volume and its storage location with:

docker volume inspect $volumename


I suspect it's somewhere in /var/run/docker/volumes

Thanks, both of you.
Now I get it that it’s more like docker question.
But still, it was helpful a lot for me.
