I have a docker-compose with environment parameters set to: USER = my

Also in odoo.conf : db_user = my

I have setup the database with also a role my:

postgres=# \l
                                  Liste des bases de données
    Nom    | Propriétaire | Encodage | Collationnement | Type caract. |    Droits d'accès     
-----------+--------------+----------+-----------------+--------------+-----------------------
 my_odoo_db | postgres     | UTF8     | fr_FR.UTF-8     | fr_FR.UTF-8  | =Tc/postgres         +
           |              |          |                 |              | postgres=CTc/postgres+
           |              |          |                 |              | my=CTc/postgres

my_odoo_db=# \du

 my          | Pas d'héritage                                                                 +| {}
             | 100 connexions                                                                  | 
 postgres    | Superutilisateur, Créer un rôle, Créer une base, Réplication, Contournement RLS | {}

But when I up docker-compose and open a shell at the web container:

tail /etc/password
odoo:x:101:101::/var/lib/odoo:/usr/sbin/nologin

I have suspected the entrypoint\.sh\ and\ commented\ the\ default\ environment\ variables\ setting:

\#\#:\ \$\{HOST:=\$\{DB_PORT_5432_TCP_ADDR:='db'\}\}
\#\#:\ \$\{PORT:=\$\{DB_PORT_5432_TCP_PORT:=5432\}\}
\#\#:\ \$\{USER:=\$\{DB_ENV_POSTGRES_USER:=\$\{POSTGRES_USER:='odoo'\}\}\}
\#\#:\ \$\{PASSWORD:=\$\{DB_ENV_POSTGRES_PASSWORD:=\$\{POSTGRES_PASSWORD:='odoo'\}\}\}

Then\ I\ have\ suppressed\ in\ the\ odoo\ Dockerfile\ the\ final\ command\ to\ launch\ odoo\ without\ parameters:

\#\ Set\ default\ user\ when\ running\ the\ container
USER\ my

ENTRYPOINT\ \["/entrypoint.sh"]
#CMD ["odoo"]

But it is the same when I check the `/etc/password` file, still user odoo instead of my.

Where am I wrong? Is it possible or is odoo user hardcoded somewhere?
