如何在 Docker Z2FEC392304A5C73AC138DA228C 容器中使用 Apache vhost URL

Question

I need to perform a cURL request from within PHP.

I don't know to access my project from inside the PHP container. myproject.local of course doesn't work as that configuration is set in the /etc/hosts file on my machine.

Apache and PHP-FPM are separate containers. Configuration below.

Apache virtualhosts

<VirtualHost *:80>
    ServerName myproject.local
    ServerAlias www.myproject.local
    
    ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://192.168.0.33:9000/usr/local/apache2/my/project$1
    SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1
    DocumentRoot /usr/local/apache2/my/project
    <Directory /usr/local/apache2/my/project>
        DirectoryIndex index.php
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

<VirtualHost *:443>
    ServerName myproject.local
    ServerAlias www.myproject.local

    SSLEngine on
    SSLCertificateFile /usr/local/apache2/conf/server.crt
    SSLCertificateKeyFile /usr/local/apache2/conf/server.key
    
    ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://192.168.0.33:9000/usr/local/apache2/my/project$1
    SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1
    DocumentRoot /usr/local/apache2/my/project
    <Directory /usr/local/apache2/my/project>
        DirectoryIndex index.php
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

docker-compose.yml

version: "3.7"
services:
    apache:
        container_name: my-project-web
        ports:
            - "80:80"
            - "443:443"
        networks:
            public_net:
                ipv4_address: 192.168.0.11
    php:
        container_name: my-project-php
        depends_on:
            - apache
        networks:
            public_net:
                ipv4_address: 192.168.0.33
networks:
    public_net:
        driver: bridge
        ipam:
            driver: default
            config:
                - subnet: 192.168.0.0/24

By default, you can connect between containers within one Docker-Compose-Environment by their names. No need to assign static IP addresses.

For your example from the PHP-Container to the Apache-Container with http://apache/ . Or from you Apache config to the PHP-FPM with fcgi://php:9000 .

But keep in mind, making requests on your own webserver is bad practise!
