phpfarm for docker

This is a build file to create a phpfarm setup. The resulting docker image will run Apache on different ports with different PHP versions accessed via FCGI. The different PHP CLI binaries are accessible as well.

CircleCI

Port PHP Version Binary
8051 5.1.6 php-5.1 (wheezy only)
8052 5.2.17 php-5.2 (wheezy only)
8053 5.3.29 php-5.3
8054 5.4.45 php-5.4
8055 5.5.38 php-5.5
8056 5.6.32 php-5.6
8070 7.0.25 php-7.0
8071 7.1.11 php-7.1
8072 7.2.0RC5 php-7.2

There are two tags for this image: wheezy and jessie, referring to the underlying Debian base system releases. If you need PHP 5.1 or 5.2 you have to use the wheezy tag, otherwise the jessie image provides a more modern environment.

Building the image

After checkout, simply run the following command:

docker build -t eugenesia/phpfarm:jessie -f Dockerfile-Jessie .
docker build -t eugenesia/phpfarm:wheezy -f Dockerfile-Wheezy .

This will setup a Debian base system, install phpfarm, download and compile the different PHP versions, extensions and setup Apache. So, yes this will take a while. See the next section for a faster alternative.

Downloading the image

Simply downloading the ready made image from Docker Hub is probably the fastest way. Just run one of these:

docker pull eugenesia/phpfarm:wheezy
docker pull eugenesia/phpfarm:jessie

Running the container

The following will run the container and map all ports to their respective ports on the local machine. The current working directory will be used as the document root for the Apache server and the server itself will run with the same user id as your current user.

docker run --rm -t -i -e APACHE_UID=$UID -v $PWD:/var/www:rw \
  -p 8051:8051 -p 8052:8052 -p 8053:8053 -p 8054:8054 -p 8055:8055 \
  -p 8056:8056 -p 8070:8070 -p 8071:8071 -p 8072:8072 \
  eugenesia/phpfarm:jessie

Above command will also remove the container again when the process is aborted with CTRL-C. While running, the Apache and PHP error log is shown on STDOUT.

You can also access the PHP binaries within the container directly. Refer to the table above for the correct names. The following command will run PHP 5.3 on your current working directory.

docker run --rm -t -i -v $PWD:/var/www:rw eugenesia/phpfarm:jessie php-5.3 --version

Alternatively you can also run an interactive shell inside the container with your current working directory mounted.

docker run --rm -t -i -v $PWD:/var/www:rw eugenesia/phpfarm:jessie /bin/bash

Loading custom php.ini settings

All PHP versions are compiled with the config-file-scan-dir pointing to /var/www/.php/. When mounting your own project as a volume to /var/www/ you can easily place custom .ini files in your project's .php directory and they should be automatically be picked up by PHP.

Using the image for Testing in Gitlab-CI

Gitlab-CI users can use this image to automate testing against different PHP versions. For detailed info refer to the gitlab-ci documentation.

Here's a simple .gitlab-ci.yml example using phpunit.

stages:
  - test

image: eugenesia/phpfarm:jessie

php-5.3:
  stage: test
  script:
    - wget https://phar.phpunit.de/phpunit-old.phar -O phpunit
    - php-5.3 phpunit --coverage-text --colors=never

php-5.4:
  stage: test
  script:
    - wget https://phar.phpunit.de/phpunit-old.phar -O phpunit
    - php-5.4 phpunit --coverage-text --colors=never

php-5.6:
  stage: test
  script:
    - wget https://phar.phpunit.de/phpunit.phar -O phpunit
    - php-5.6 phpunit --coverage-text --colors=never

php-7.0:
  stage: test
  script:
    - wget https://phar.phpunit.de/phpunit.phar -O phpunit
    - php-7.0 phpunit --coverage-text --colors=never

Supported PHP extensions

Here's a list of the extensions available in each of the PHP versions. It should cover all the default extensions plus a few popular ones and xdebug for debugging.
