How to run php-fpm in docker not as root?

Question

PHP

I use a ready-made assembly of phpdocker.io with nginx and php-fpm
But the question is also relevant for any independent assembly
When entering the php-fpm container, all files are created from root (in particular, in symfony via bin/console make)
I tried to prescribe in docker-compose in the environment section, php_fpm_user variables, files in the container have rights from the exposed user, but when created from the container, they are still created as root . Tried to
pass the user through the file /phpdocker/php-fpm/pool.d/www.conf user = www-data group = www-data but the situation is the same

In general, the phpdocker assembly is configured this way, I myself assembled the assembly from images, registered the user in the php-fpm dockerfile and everything is created from him in the container
