Easy installation of PHP extensions in official PHP Docker images

This repository contains a script that can be used to easily install a PHP extension inside the official PHP Docker images.

The script works both for Alpine and Debian Linux.

Usage

Here's a sample Dockerfile that installs the GD and xdedub extensions inside a docker image:

FROM php:7.2-cli

ADD https://raw.githubusercontent.com/mlocati/docker-php-extension-installer/master/install-php-extensions /usr/local/bin/

RUN chmod uga+x /usr/local/bin/install-php-extensions && sync && \
    install-php-extensions gd xdebug

Installation via COPY --from

FROM php:7.2-cli

COPY --from=mlocati/php-extension-installer /usr/bin/install-php-extensions /usr/bin/

RUN install-php-extensions gd xdebug

install-php-extensions will install all the required APT/APK packages; at the end of the script execution, the no-more needed packages will be removed.

PS: the pre-installed PHP extensions are excluded from this list. You can list them with the following command (change php:7.2-cli to reflect the PHP version you are interested in):

docker run --rm -it php:7.2-cli php -m

Special requirements

Some extension has special requirements:

Extension	Requirements
parallel	Requires images with PHP compiled with thread-safety enabled (zts).
pthreads	Requires images with PHP compiled with thread-safety enabled (zts).

How to contribute

• If you want to add support for a new PHP extension:
  1. change the install-php-extensions script
  2. update the data/supported-extensions file, adding a new line with the handle of the extension and the list of supported PHP versions
  3. if the extension requires ZTS images:
     add a new line to the data/special-requirements file, with the extension handle followed by a space and zts
• If you want to change the list of supported PHP versions for an already supported extension:
  1. change the install-php-extensions script
  2. update the data/supported-extensions file, adding the new PHP version to the existing line corresponding to the updated extension
• If you change some code that affects one or more extensions, please add a line with Test: extension1, extension2 to the message of one of the pull request commits. Here's an example of a commit message:

  Improve the GD and ZIP extensions
  
  Test: gd, zip
  

  If your pull request contains multiple commits, we'll check the "Test:" message of every commit. If you want to stop parsing next commits, add -STOP- in the "Test:" line, for example:

  Improve the GD and ZIP extensions
  
  Test: gd, zip, -STOP-
