    I had the same problem today and after lots of unsuccessful attempts, I think adding expose helped :

    db:
  image: mysql:5.7
  volumes:
    - db_data:/var/lib/mysql
  restart: always
  environment:
    MYSQL_ROOT_PASSWORD: somewordpress
    MYSQL_DATABASE: wordpress
    MYSQL_USER: wordpress
    MYSQL_PASSWORD: wordpress
  expose:
    -"3306"

    firstly, your title is "how to use wp with nginx" but in your docker compose file, you are clearly pulling a wordpress:apache image.
    secondly, you can delete the whole content related to nginx since that container runs alone and outside the scope of your wordpress.

    now, that you only have wordpress and db as services in your yml file (which is how it should be), you must add a ports directive to wordpress:

        ports:
        - 80:80

    And finally, for the containers to be able to resolve their ips within the same network, you need to add this at the end of your yml file:

    volumes:
  wordpress:
  db:

    Now this will ensure you’re running a wordpress with a db, and the wordpress image runs apache (which is httpd, not nginx).

    Thirdly, if you’re not satisfied with httpd and want an nginx container, you’ll need to look for a wordpress image on hub.docker.com that runs on nginx.
