Alias and passwd can't be set at first run

[revher]

Thank you for your add on which is more recent docker than from mgodlewski. Before my question which is the title, I would like to describe what I did:

Therefore there are few differences that I remarked during the installation and mentioned above like the name given by the standard installation which is diacamma-app-1 as well as the name of the backup and restore script which are backup.sh and restore.sh

But, and here I am stuck with the Alias and passwd which are supposed to be empty at the first launch at 127.0.0.1:8100 but they are not and the message is Alias ou mot de passe incorrect !
And I don't know how to get them from the database at
$ docker exec diacamma-app-1 ls -l /var/lucterios2/mon-syndic/db.sqlite3
-rw-r--r--. 1 root root 4456448 Jan 15 17:15 /var/lucterios2/mon-syndic/db.sqlite3

Many thanks for your potential help.
