How to change the default installation path [/var/www/html] ?

I use docker compose and prestashop PHP-FPM image, however we need a HTTP server.

But the default image httpd (apache), uses as default path : /usr/local/apache2/htdocs

Prestashop image is configured by default to : /var/www/html

Is it possible to modify this ?

I looked in the environment variables but I didn't find anything.

Here is my problem :

services:

  apache:
    image: httpd:2.4
    restart: always
    ports:
      - 8080:80
    volumes:
      - ./:/usr/local/apache2/htdocs # volume not shared <------
      - php-socket:/run/php
    networks:
      - front

  ...
  here mariadb ...
  ...

  php-fpm:
    image: prestashop/prestashop:1.7.8.6-7.4-fpm
    restart: always
    ports:
      - 9000:9000
    volumes:
      - ./:/var/www/html # volume not shared <------
      - ./.docker/zz-docker.conf:/usr/local/etc/php-fpm.d/zz-docker.conf
      - php-socket:/run/php
    networks:
      - front

volumes:
  php-socket:

networks:
  front:

But as there are two different paths, the volumes are not sharing and will return an error : File not found.

Do I have to modify the default HTTPD image Apache DocumentRoot (and create/var/www/html to copy files) ?
Or is there another solution ?

Start with the Docker Compose example in the issue and compare the mounted paths /usr/local/apache2/htdocs and /var/www/html used by the Apache and PrestaShop PHP-FPM containers. Determine whether the project documents a supported way to align these paths or configure Apache's DocumentRoot; done means the documented setup shares the application files without the reported File not found error.
