Full Description

PHP Base Image

This is a minimal php 5.5 base image with apache2 configured. It has friendly settings for form handling and supports both access and error logging to stdout.

Extending this image

This image can be used as a standard web server for most PHP apps. It is sufficient to add a .htaccess file to
the server root to set up redirects, etc. If you need composer, see the deardooley/php-composer image.

Developing with this image

If you are developing with this image, mount your code into the /var/www/html directory in the container. Your local changes will be reflected instantly when you refresh your page.

docker run -h docker.example.com
           -p 80:80 \
           --name apache \
           -v `pwd`:/var/www/html \
           --link mysql:mysql
           -e DOCUMENT_ROOT=/var/www/html
           deardooley/php:5.6

Alternatively, you can specify a different web root if needed by your application. For example, if you had a Laravel project where the project composer.json file was located at /usr/local/src/laravel/composer.json, the following would start the container with the proper web root for the project.

docker run -h docker.example.com
           -p 80:80 \
           --name apache \
           -v /usr/local/src/laravel:/var/www \
           --link mysql:mysql
           -e DOCUMENT_ROOT=/var/www/public
           deardooley/php:5.6

Running in production

When running in production, both the access and error logs will stream to standard out so they can be access via the Docker logs facility by default.

docker run -h docker.example.com \
           -p 80:80 \
           -p 443:443 \
           --name apache \
           deardooley/php:5.6

docker logs apache

SSL Support

To add ssl support, volume mount your ssl cert, key, ca cert file, and ca chain file as needed. In the following example, a folder containing the necessary files is volume mounted to /ssl in the container.

docker run -h docker.example.com \
           -p 80:80 \
           -p 443:443 \
           --name apache \
           -v `pwd`/ssl:/ssl:ro \
           -e SSL_CERT=/ssl/docker_example_com_cert.cer \
           -e SSL_KEY=/ssl/docker.example.com.key \
           -e SSL_CA_CERT=/ssl/docker_example_com.cer \
           deardooley/php:5.6

Email Server

There is no embedded mail server in this image. In order to use the PHP mail() command, you will need to configure a SMTP relay server through your environment.

Variable Description
SMTP_HUB Hostname and port of the SMTP relay server. ex. "smtp.sendgrid.net:587"
SMTP_USER Account username used to authenticate to the SMTP relay
SMTP_PASSWORD Account password used to authenticate to the SMTP relay
SMTP_FROM_ADDRESS Email address used in the from field ex. noreply@example.com
SMTP_TLS 1 if TLS should be used, 0 otherwise. Default is 1
docker run -h docker.example.com \
           -p 80:80 \
           -p 443:443 \
           --name apache \
           -v `pwd`/ssl:/ssl:ro \
           -e SMTP_HUB="smtp.sendgrid.net:587" \
           -e SMTP_USER=username \
           -e SMTP_PASSWORD=password \
           -e SMTP_FROM_ADDRESS="noreply@example.com" \
           -e SMTP_TLS=1 \
           -e SSL_CERT=/ssl/docker_example_com_cert.cer \
           -e SSL_KEY=/ssl/docker.example.com.key \
           -e SSL_CA_CERT=/ssl/docker_example_com.cer \
