Docker-compose permission error, chown not working - php

Question

Trying to set a laravel project with redis, mysql and mongodb. Using docker-compose to set docker containers, but 127.0.0.1 throws The stream or file "/var/www/html/storage/logs/laravel.log" could not be opened: failed to open stream: Permission denied. Chown'ing directory but owner of /var/www/html inside 'app' container is root, not www-data. How can I fix it?
