I'm trying to do a local build from the production Dockerfile, but I keep getting a weird problem.  The build seems to go okay, but the files in the www folder never get created (except for the folder created in the entrypoint.sh).  For what its worth, the relevant portion of my compose file is   www:
    depends_on:
      - db
    #image: farmos/farmos:7.x-1.5
    build: .
    volumes:
      - './www:/var/www/html:delegated'
      - './farmdata2files:/farmdata2files:delegated'
    ports:
      - '80:80'
    environment:
      XDEBUG_CONFIG: remote_host=172.17.0.1
