Docker volume wrong ownership

I'm trying to configure Odoo for Docker on Windows, but Docker keeps telling me that some of the shared volumes have wrong ownership.

It's the pgdata and modules that gives me errors.

Before initialising the containers I'm creating the folders on Windows.

version: '3.3'
services:
  odoo:
    build:
      context: https://github.com/EmilMoe/odoo10.git
    volumes:
      - ./odoo.conf:/etc/odoo/odoo.conf
      - ./addons:/mnt/addons
      - ./data:/var/lib/odoo
      - ./modules:/usr/lib/python2.7/dist-packages/odoo
    ports:
      - "8069:8069"

  db:
    image: postgres:9.6
    environment:
      - POSTGRES_PASSWORD=odoo
      - POSTGRES_USER=odoo
      - PGDATA=/var/lib/postgresql/data/pgdata
    volumes:
      - ./pgdata:/var/lib/postgresql/data/pgdata
    ports:
      - "5432:5432"
