%%IMAGE%%:<version>-apache

This image contains Debian's Apache httpd in conjunction with PHP (as mod_php) and uses mpm_prefork by default.

Apache with a Dockerfile

FROM %%IMAGE%%:7.2-apache
COPY src/ /var/www/html/

Where src/ is the directory containing all your PHP code. Then, run the commands to build and run the Docker image:

$ docker build -t my-php-app .
$ docker run -d --name my-running-app my-php-app

We recommend that you add a php.ini configuration file; see the "Configuration" section for details.

Apache without a Dockerfile

$ docker run -d -p 80:80 --name my-apache-php-app -v "$PWD":/var/www/html %%IMAGE%%:7.2-apache

Changing DocumentRoot (or other Apache configuration)

Some applications may wish to change the default DocumentRoot in Apache (away from /var/www/html). The following demonstrates one way to do so using an environment variable (which can then be modified at container runtime as well):

FROM %%IMAGE%%:7.1-apache

ENV APACHE_DOCUMENT_ROOT /path/to/new/root

RUN sed -ri -e 's!/var/www/html!${APACHE_DOCUMENT_ROOT}!g' /etc/apache2/sites-available/*.conf
RUN sed -ri -e 's!/var/www/!${APACHE_DOCUMENT_ROOT}!g' /etc/apache2/apache2.conf /etc/apache2/conf-available/*.conf

A similar technique could be employed for other Apache configuration options.
