How to properly set up chmod for laravel?

Question

Access rights

It is not possible to properly configure chmod folder permissions for laravel.
Found a topic on stackoverflow

Did everything as written there

sudo chown -R $USER:www-data .
sudo find . -type f -exec chmod 664 {} \;   
sudo find . -type d -exec chmod 775 {} \;
sudo chgrp -R www-data storage bootstrap/cache
sudo chmod -R ug+rwx storage bootstrap/cache

But there is a problem, the cache is not cleared.
php artisan cache:clear gives error (works with sudo)

Failed to clear cache. Make sure you have the appropriate permissions.

The most interesting thing is that immediately after executing
sudo chmod -R ug + rwx storage bootstrap/cache
php artisan cache: clear works fine, it clears everything, but if you go to the site, as I understand it, a new cache file is created with rights that do not allow you to delete this file, why is this happening and how can I deal with it?
For the first time such a problem, past sites were loaded without problems, but here, apparently, something was written wrong.

This means that your web server is most likely running as root.
Wait until the file is created again and execute ls -l bootstrap/cache- you will see which user the web server is running under.
