hi all,

I just installed odoo 12 on ubuntu 18 under docker container using the docker-compose.yml file below,

and I want to install extra module addons, I executed some commands to mount extra addons folder but always I have errors

docker-compose.yml

services:

  db:

    image: postgres:10.0

    environment:

      - POSTGRES_PASSWORD=odoo

      - POSTGRES_USER=odoo

      - POSTGRES_DB=postgres

    restart: always             # run as a service
