The php-fpm process runs containerized. The php application always uses /var/www as it's work directory and home folder, and if /var/www is bind mounted it is necessary to adjust the path passed via FastCGI to php-fpm by changing the root directory to /var/www. This can achieved in nginx by setting the fastcgi_param SCRIPT_FILENAME to /var/www/$fastcgi_script_name;
