Hi guys,
I'm trying to run a docker for my ERP (Dolibarr) + database (mariadb).
Currently it's a mess : days and days of head scratching for almost nothing working. So well, I'm here 
I try to use tuxgasy/dolibarr (https://github.com/tuxgasy/docker-dolibarr)
The problem is : volumes created for Dolibarr in the docker-compose.yml are not populated by files during the build.
So, in my way of debugging this, I found that volume created for mariadb is populated by files (ok, cool !) but the user owner is "openmediavault-webgui".
I don't understand because I do everything with CLI and root access.
Don't know if it's related to dolibarr volumes's problem, so I prefer to check this point first.
What is that user and why he's owner of files who are supposed to be owned by root ??
Thanks
Olivier
