armel/php repository overview

⁠DEPRECATED

The armel⁠ organization is deprecated in favor of the more-specific arm32v5⁠ organization, as per https://github.com/docker-library/official-images#architectures-other-than-amd64⁠. Please adjust your usages accordingly.

⁠Supported tags and respective Dockerfile links

** THESE IMAGES ARE VERY EXPERIMENTAL; THEY ARE PROVIDED ON A BEST-EFFORT BASIS WHILE docker-library/official-images#2289⁠ IS STILL IN-PROGRESS (which is the first step towards proper multiarch images) **

** PLEASE DO NOT USE THEM FOR IMPORTANT THINGS **

This image is built from the source of the official image of the same name (php)⁠. Please see that image's description for links to the relevant Dockerfiles.

If you are curious about specifically how this image differs, see the Jenkins Groovy DSL scripts in the tianon/jenkins-groovy GitHub repository⁠, which are responsible for creating the Jenkins jobs which build them.

⁠What is PHP?

PHP is a server-side scripting language designed for web development, but which can also be used as a general-purpose programming language. PHP can be added to straight HTML or it can be used with a variety of templating engines and web frameworks. PHP code is usually processed by an interpreter, which is either implemented as a native module on the web-server or as a common gateway interface (CGI).

⁠How to use this image.

⁠With Command Line

For PHP projects run through the command line interface (CLI), you can do the following.

⁠Create a Dockerfile in your PHP project

FROM php:7.0-cli
COPY . /usr/src/myapp
WORKDIR /usr/src/myapp
CMD [ "php", "./your-script.php" ]

Then, run the commands to build and run the Docker image:

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

⁠Run a single PHP script

For many simple, single file projects, you may find it inconvenient to write a complete Dockerfile. In such cases, you can run a PHP script by using the PHP Docker image directly:

$ docker run -it --rm --name my-running-script -v "$PWD":/usr/src/myapp -w /usr/src/myapp php:7.0-cli php your-script.php

⁠With Apache

More commonly, you will probably want to run PHP in conjunction with Apache httpd. Conveniently, there's a version of the PHP container that's packaged with the Apache web server.

⁠Create a Dockerfile in your PHP project

FROM php:7.0-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 custom php.ini configuration. COPY it into /usr/local/etc/php by adding one more line to the Dockerfile above and running the same commands to build and run:

FROM php:7.0-apache
COPY config/php.ini /usr/local/etc/php/
COPY src/ /var/www/html/

Where src/ is the directory containing all your PHP code and config/ contains your php.ini file.

⁠How to install more PHP extensions

We provide the helper scripts docker-php-ext-configure, docker-php-ext-install, and docker-php-ext-enable to more easily install PHP extensions.

In order to keep the images smaller, PHP's source is kept in a compressed tar file. To facilitate linking of PHP's source with any extension, we also provide the helper script docker-php-source to easily extract the tar or delete the extracted source. Note: if you do use docker-php-source to extract the source, be sure to delete it in the same layer of the docker image.

FROM php:7.0-apache
RUN docker-php-source extract \
	# do important things \
	&& docker-php-source delete

⁠PHP Core Extensions

For example, if you want to have a PHP-FPM image with iconv, mcrypt and gd extensions, you can inherit the base image that you like, and write your own Dockerfile like this:

FROM php:7.0-fpm
RUN apt-get update && apt-get install -y \
		libfreetype6-dev \
		libjpeg62-turbo-dev \
		libmcrypt-dev \
		libpng12-dev \
	&& docker-php-ext-install -j$(nproc) iconv mcrypt \
	&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
	&& docker-php-ext-install -j$(nproc) gd

Remember, you must install dependencies for your extensions manually. If an extension needs custom configure arguments, you can use the docker-php-ext-configure script like this example. There is no need to run docker-php-source manually in this case, since that is handled by the configure and install scripts.

⁠PECL extensions

Some extensions are not provided with the PHP source, but are instead available through PECL⁠. To install a PECL extension, use pecl install to download and compile it, then use docker-php-ext-enable to enable it:

FROM php:7.1-fpm
RUN pecl install redis-3.1.0 \
	&& pecl install xdebug-2.5.0 \
	&& docker-php-ext-enable redis xdebug

FROM php:5.6-fpm
RUN apt-get update && apt-get install -y libmemcached-dev zlib1g-dev \
	&& pecl install memcached-2.2.0 \
	&& docker-php-ext-enable memcached

⁠Other extensions

Some extensions are not provided via either Core or PECL; these can be installed too, although the process is less automated:

FROM php:5.6-apache
RUN curl -fsSL 'https://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.gz' -o xcache.tar.gz \
	&& mkdir -p xcache \
	&& tar -xf xcache.tar.gz -C xcache --strip-components=1 \
	&& rm xcache.tar.gz \
	&& ( \
		cd xcache \
		&& phpize \
		&& ./configure --enable-xcache \
		&& make -j$(nproc) \
		&& make install \
	) \
	&& rm -r xcache \
	&& docker-php-ext-enable xcache

The docker-php-ext-* scripts can accept an arbitrary path, but it must be absolute (to disambiguate from built-in extension names), so the above example could also be written as the following:

FROM php:5.6-apache
RUN curl -fsSL 'https://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.gz' -o xcache.tar.gz \
	&& mkdir -p /tmp/xcache \
	&& tar -xf xcache.tar.gz -C /tmp/xcache --strip-components=1 \
	&& rm xcache.tar.gz \
	&& docker-php-ext-configure /tmp/xcache --enable-xcache \
	&& docker-php-ext-install /tmp/xcache \
	&& rm -r /tmp/xcache

⁠Without a Dockerfile

If you don't want to include a Dockerfile in your project, it is sufficient to do the following:

$ docker run -d -p 80:80 --name my-apache-php-app -v "$PWD":/var/www/html php:7.0-apache
