multiple sites on docker container – Apache

I am completely new to docker, php and apache, I am trying to run my sample website on apache server in a docker container. It works fine. And my dockerfile is following:

From php:7.2-apache
Copy Site/ /var/www/html/
Run echo "ServerName localhost" >> /etc/apache2/apache2.conf
RUN docker-php-ext-install pdo pdo_mysql
Expose 80

How can I have another website on the same apache sever in the docker container, for example "website1", in xampp I could change the httpd.conf file and add virtual host. but what should I do in docker container?

Update

============================================

I update the files as the following, This is docker-compose.yml

 version: '3.9'
services:
    apache:
        build: .
        container_name: php_cont
        volumes:
            - './apache2.conf:/etc/apache2/apache2.conf'
            - './Site1/site1.conf:/etc/apache2/sites-available/site1.conf'
            - './Site2/site2.conf:/etc/apache2/sites-available/site2.conf'
        ports:
            - '80:80'

This is the site.conf

 <VirtualHost *:80>
 DocumentRoot "d:TempSite1"
 ServerName site1Name
 <Directory "d:TempSite1">
 </Directory>
 </VirtualHost>

This is the site2.conf

 <VirtualHost *:80>
 DocumentRoot "d:TempSite2"
 ServerName site2Name
 <Directory "d:TempSite2">
 </Directory>
 </VirtualHost>

and I addded these two line to hosts file in windows=>system32=>driver=>etc

  127.0.0.1 site1Name
  127.0.0.1 site2Name

but when I surf to site1Name or site2Name on the browser, there is no success!

    The idea of Docker is that every application (website in you case) has its own environment. You can then upgrade the PHP version for one application without affecting the others. So you should have a Dockerfile per website.

    To answer your question “how to direct visitors to the correct container?”: please take a look into Reverse Proxies. There are plenty of Docker images available like Nginx and Traefik. These can also take care of SSL certificates for instance.

    I recommend you using Docker Compose, but you also can use Volume in both docker run command and docker-compose.

    docker-compose

    First of all let’s see docker-compose. Create a file called docker-compose.yml with the following contents:

    version: '3.9'

services:
    apache:
        build: .
        hostname: OPTIONAL
        container_name: OPTIONAL
        volumes:
            - './apache/apache2.conf:/etc/apache2/apache2.conf'
            - './apache/site1.conf:/etc/apache2/sites-available/site1.conf'
        ports:
            - '80:80'

    The two keywords hostname and container_name are optional and you can change their values or even remove these two lines.

    Regarding volumes, copy your apache2.conf to a path like ./apache and do your edits in this file.

    Then add another file called site1.conf. Here is my conf file as an example:

    <VirtualHost *:80>
        ServerName some_name.com

        ServerAdmin webmaster@name
        DocumentRoot /var/www/html


        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

    For each site you can create another file and add it to volumes.

    Now after everything is done, run this command:

    docker-compose up -d

    docker run command

    If you want to use docker run command, you can do like this (the above paths in ./apache in the below are the same):

    docker run IMAGE_NAME -v './apache/apache2.conf:/etc/apache2/apache2.conf' -v './apache/site1.conf:/etc/apache2/sites-available/site1.conf' -dp80:80

    Edit your Dockerfile:

    From php:7.2-apache
Copy Site/ /var/www/html/
Run echo "ServerName localhost" >> /etc/apache2/apache2.conf
COPY site1.conf /etc/apache2/apache2.conf
COPY site2.conf /etc/apache2/apache2.conf
COPY apache2.sh /root/
RUN bash /root/apache2.sh
RUN rm /root/apache2.sh
RUN docker-php-ext-install pdo pdo_mysql
Expose 80

    apache2.sh:

    service apache2 start
a2ensite site1
a2ensite site2
service apache2 restart
