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.
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
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.
Dockerfile in your PHP project
FROM php:7.0-apache COPY src/ /var/www/html/
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
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/
src/ is the directory containing all your PHP code and
config/ contains your
How to install more PHP extensions
We provide the helper scripts
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
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
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
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
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
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
php images come in many flavors, each designed for a specific use case.
This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.
This image is based on the popular Alpine Linux project, available in the
alpine official image. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.
This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use musl libc instead of glibc and friends, so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See this Hacker News comment thread for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.
To minimize image size, it's uncommon for additional related tools (such as
bash) to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile (see the
alpine image description for examples of how to install packages if you are unfamiliar).

I'm trying to install yaml extension from php 7.1.5 alpine:
This is my docker file
RUN apk add --update yaml yaml-dev
RUN pecl channel-update pecl.php.net
RUN pecl install yaml-2.0.0 && docker-php-ext-enable yaml
But it gives me this error:
annot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.
ERROR: `phpize' failed
ERROR: Service 'php_env' failed to build: The command '/bin/sh -c pecl install yaml-2.0.0 && docker-php-ext-enable yaml' returned a non-zero code: 1
Any idea why when i launch the php7.1-apache image via :
docker run -d --name apache -p 8080:80 php:7.1-apache
It is normal that I receive a Forbidden access on my browser?
Is there possibility to run cron inside this image?
Due to Microsoft's announcement for support PHP7.0 with pdo_sqlsrv already (Ref:https://www.microsoft.com/en-us/sql-server/developer-get-started/php-ubuntu). Could you please suggest how can we install this module on image: php:7.0-apache ?
Could you please make Alpine image with Apache?
When can we expect the 7.1.2 release. Should this not be automated as its an official channel?
just put this code in your docker-compose.yml file
volumes: - ./your/php/ini/path:/etc/php5/apache2/conf.d/php.ini - ./your/php/ini/path:/usr/local/etc/php/php.ini
I figured out at last!
php.ini for apache2
php.ini for command-line php
How can I add common php.ini for both?
