Answer 1

In your DB section in the docker compose file

Change this:

• ./data-db:/var/lib/mysql

For this:

• data-db:/var/lib/mysql

Is not a bind to a folder what you have, data-db is a volume like the media one

Answer 2

You can try to edit the db service in docker-compose.yml with the following changes:

volumes:
  # - ./init-db:/docker-entrypoint-initdb.d
  - ./data-db:/var/lib/mysql:rw # <- permissions
user: mysql # <- user
