I'm been trying to deploy and run odoo app using docker on Azure app service for containers. I would like to use odoo.conf residing on Azure Blob Container, but for some reasons, odoo still uses the default values to connect to database as if it doesn't find the proper database credentials. Below is docker-compose in Azure: 

services:

  web:

    image: myazureacr.io/my-odoo-image:latest

    depends_on:

      - db

    ports:

      - "8099:8069"

    entrypoint:

      - odoo

      - -i

      - base

      - -d

      - demo_odoo_database

    environment:

      DB_HOST: db            

      DB_PORT: 5432

      DB_USER: user         

      DB_PASSWORD:  my_password  

      DB_NAME: postgres

    volumes:

      - filestore:/var/lib/odoo

      - odoo-config:/etc/odoo

    networks:

      - webnet

  db:

    image: myazureacr.io/postgres:15

    ports:

      - "6432:5432"

    environment:

      - POSTGRES_DB=postgres

      - POSTGRES_PASSWORD=my_password

      - POSTGRES_USER=user

      - PGDATA=/var/lib/postgresql/data/pgdata

    volumes:

      - odoo-db:/var/lib/postgresql/data/pgdata

    networks:

      - webnet

volumes:

  odoo-db:

    external: true

  filestore:

    external: true

  odoo-config:

    external: true

networks:

  webnet:

Please note that the volumes (odoo-db, filestore, odoo-config) are external storage that reside on Azure File Share and Blob container. 

Could you please help out here ? I'd most grateful. I'd happy to provide more details. 
Or maybe, you could give a link to an article for deploying odoo properly on Azure using docker and postgres. 

Thanks.
