docker fpm-alpine image with apache reverse proxy #350

Describe the bug

The default security.limit_extensions in php-fpm.d/www.conf doesn't allow the php-fpm to serve the other files.

To Reproduce

Use this docker-compose

# cat docker-compose.yml
version: "3.8"
services:
  mariadb:
    image: 'mariadb:10.5.13'
    restart: always
    hostname: 'mariadb'
    environment:
      MYSQL_ROOT_PASSWORD: 1234
    volumes:
      - './volumes/mariadb/varlibmysql:/var/lib/mysql'
    ports:
      - 192.168.1.2:3307:3306
    networks:
      mariadb:
  phpmyadmin:
    image: 'phpmyadmin:5.1.1-fpm-alpine'

    hostname: 'phpmyadmin'
    ports:

                ServerName phpmyadmin.local.lan

Additional context

The documentation doesn't say anything about the apache reverse proxy so... I think we also need an example for apache. For example the /var/www/html is needed to be appended to the proxypass took me a little bit to figure out.
Maybe also something to redirect / to index.php? in my solution / still says File not found.
Chrome refuses to show everything probably because of X-Content-Type-Options which if forcely removed will still cause it to render weirdly.
