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).

wikipedia.org/wiki/PHP

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

FROM php:7.2-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

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:7.2-cli php your-script.php

Note that all variants of the php image contain the PHP cli.

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.

FROM php: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.

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:7.2-apache

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 php: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

Many extensions are already compiled into the image, so it's worth checking the output of php -m or php -i before going through the effort of compiling more.

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

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

FROM php:7.2-fpm
RUN apt-get update && apt-get install -y \
		libfreetype6-dev \
		libjpeg62-turbo-dev \
		libpng-dev \
	&& docker-php-ext-install -j$(nproc) iconv \
	&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
	&& docker-php-ext-install -j$(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.

See "Dockerizing Compiled Software" for a description of the technique Tianon uses for determining the necessary build-time dependencies for any bit of software (which applies directly to compiling PHP 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:7.2-fpm
RUN pecl install redis-4.0.1 \
	&& pecl install xdebug-2.6.0 \
	&& 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

It is strongly recommended that users use an explicit version number in their pecl install invocations to ensure proper PHP version compatibility (PECL does not check the PHP version compatiblity when choosing a version of the extension to install, but does when trying to install it).

For example, memcached-2.2.0 has no PHP version constraints (https://pecl.php.net/package/memcached/2.2.0), but memcached-3.0.4 requires PHP 7.0.0 or newer (https://pecl.php.net/package/memcached/3.0.4). When doing pecl install memcached (no specific version) on PHP 5.6, PECL will try to install the latest release and fail.

Beyond the compatibility issue, it's also a good practice to ensure you know when your dependencies receive updates and can control those updates directly.

Unlike PHP core extensions, PECL extensions should be installed in series to fail properly if something went wrong. Otherwise errors are just skipped by PECL.

For example, pecl install memcached-2.2.0 && pecl install redis-2.2.8 instead of pecl install memcached-2.2.0 redis-2.2.8. However, docker-php-ext-enable memcached redis is fine to be all in one command.

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

For running the FPM variants as an arbitrary user, the --user flag to docker run should be used (which can accept both a username/group in the container's /etc/passwd file like --user daemon or a specific UID/GID like --user 1000:1000).

For running the Apache variants as an arbitrary user, there are several choices:

• If your kernel is version 4.11 or newer, you can add --sysctl net.ipv4.ip_unprivileged_port_start=0 and then --user should work as it does for FPM.
• If you adjust the Apache configuration to use an "unprivileged" port (greater than 1024 by default), then --user should work as it does for FPM regardless of kernel version.
• Otherwise, setting APACHE_RUN_USER and/or APACHE_RUN_GROUP should have the desired effect (for example, -e APACHE_RUN_USER=daemon or -e APACHE_RUN_USER=#1000 -- see the Apache User directive documentation for details on the expected syntax).

As of docker-library/php#542, this image blocks the installation of Debian's PHP packages. There is some additional discussion of this change in docker-library/php#551 (comment), but the gist is that installing Debian's PHP packages in this image leads to two conflicting installations of PHP in a single image, which is almost certainly not the intended outcome.

For those broken by this change and looking for a workaround to apply in the meantime while a proper fix is developed, adding the following simple line to your Dockerfile should remove the block (with the strong caveat that this will allow the installation of a second installation of PHP, which is definitely not what you're looking for unless you really know what you're doing):

RUN rm /etc/apt/preferences.d/no-debian-php

The proper solution to this error is to either use FROM debian:XXX and install Debian's PHP packages directly, or to use docker-php-ext-install, pecl, and/or phpize to install the necessary additional extensions and utilities.

This image ships with the default php.ini-development and php.ini-production configuration files.

It is strongly recommended to use the production config for images used in production environments!

The default config can be customized by copying configuration files into the $PHP_INI_DIR/conf.d/ directory.

FROM php:7.2-fpm-alpine

# Use the default production configuration
RUN mv $PHP_INI_DIR/php.ini-production $PHP_INI_DIR/php.ini

# Override with custom opcache settings
COPY config/opcache.ini $PHP_INI_DIR/conf.d/

Where config/ contains your custom configuration files.

The 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.

Some of these tags may have names like jessie or stretch in them. These are the suite code names for releases of Debian and indicate which release the image is based on.

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 git or 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).

View license information for the software contained in this image.

As with all Docker images, these likely also contain other software which may be under other licenses (such as Bash, etc from the base distribution, along with any direct or indirect dependencies of the primary software being contained).

Some additional license information which was able to be auto-detected might be found in the repo-info repository's php/ directory.

As for any pre-built image usage, it is the image user's responsibility to ensure that any use of this image complies with any relevant licenses for all software contained within.
