Permission local folder

I’m using the official WordPress image, I’ve put my local wp-content folder into the container (/ usr / www / html / wp-content) but when I try to copy some files to that folder (local) and reflect on the container Theme for example) I am not allowed to write to my local folder because the permission is set for the apache www-data user.

my docker-compose

version: '2'

services:

  wordpress:
    image: wordpress
    volumes:
     - ./wp-content/:/var/www/html/wp-content
    ports:
      - 8080:80
    environment:
      WORDPRESS_DB_PASSWORD: wpdocker

  mysql:
    image: mariadb
    environment:
      MYSQL_ROOT_PASSWORD: wpdocker
