[SOLVED] Why Apache container can't see PHP container?

Hello,
I have two YAML files as follows:

Code:

version: '3.9'
networks:
  phpnet:
    driver: bridge
    name: My_Network
services:
  web:
    image: nginx:latest
    ports:
      - '8080:80'
    volumes:
      - ./default.conf:/etc/nginx/conf.d/default.conf
      - /var/www/html:/usr/share/nginx/html
    networks:
      - phpnet
    depends_on:
       - php-fpm
  php-fpm:
    image: php:8-fpm
    volumes:
       - /var/www/html:/usr/share/nginx/html/
       - /var/www/html:/usr/local/apache2/htdocs/
    networks:
      - phpnet

And:

Code:

version: '3.9'
networks:
  apache:
    external: true
    name: My_Network
services:
    httpd:
        ports:
            - '80:80'
        volumes:
            - /var/www/html:/usr/local/apache2/htdocs/
            - ./httpd.conf:/usr/local/apache2/conf/httpd.conf
        image: 'httpd:latest'
        networks:
            - apache

The network is also built by Docker:

Code:

# docker network list
NETWORK ID     NAME               DRIVER    SCOPE
b36954410da3   My_Network         bridge    local
385e912fff96   bridge             bridge    local
7b3a9c0ec7dd   host               host      local
fb5635eda3c3   nginx-php_phpnet   bridge    local
d851ead577b7   none               null      local
b13678883aac   redis_default      bridge    local

But:

Code:

# curl http://172.20.2.58:8080/index.php
Testing PHP-FPM on Docker.
#
# curl http://172.20.2.58:80/index.php
<?php
echo "Testing PHP-FPM on Docker."
?>

As you can see, Apache cannot compile PHP file. What is wrong?

Thank you.

Hello,
This problem was solved by adding the following lines to the httpd.conf file:

Code:

LoadModule proxy_module modules/mod_proxy.so
LoadModule rewrite_module modules/mod_rewrite.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so

<IfModule dir_module>
    DirectoryIndex index.php index.html
</IfModule>


DocumentRoot "/usr/local/apache2/htdocs"
<Directory "/usr/local/apache2/htdocs">
    Options Indexes FollowSymLinks
    AllowOverride None
Require all granted
</Directory>

<IfModule proxy_module>
    <FilesMatch "\.php$">
        SetHandler  "proxy:fcgi://php-fpm:9000"
    </FilesMatch>
</IfModule>
