Docker compose for odoo:14 and PostgreSQL:13

docker-compose.yml

version: '3'
services:
  db:
    image: postgres:13
    volumes:
      - db-data:/var/lib/postgresql/data/pgdata
    ports:
      - 5432:5432/tcp
    environment:
    - POSTGRES_PASSWORD=odoo
    - POSTGRES_USER=odoo
    - POSTGRES_DB=postgres
    - PGDATA=/var/lib/postgresql/data/pgdata
  web:
    image: odoo:14.0
    depends_on:
      - db
    ports:
      - "8069:8069/tcp"
    volumes:
      - web-data:/var/lib/odoo
      - ./config:/etc/odoo
      - ./addons:/mnt/extra-addons
volumes:
  db-data:
    driver: local
  web-data:
    driver: local

I use these containers the next way:

1. Create addons and config folders
2. Run sudo chmod -R 777 addons (We need it writable from inside the docker container, for example for an odoo_bin utility)
3. Run docker-compose up -d
4. Generate a module docker exec -d odoo-test_web_1 /usr/bin/odoo scaffold openacademy /mnt/extra-addons && sudo chown -R pavel:pavel addons/openacademy (pavel is a my user . If we don't change an owner we will not be able to edit a source code outside the container)
