Installing additional modules

Extension names should not include a php or release version and must be comma separated without trailing comma. Example: PHP_EXTENSIONS="sockets,yaml". See the links section for a list of extensions that can be installed from PHP.earth.

PHP configuration

The following php.ini directives are changed from their default values:

Name	Value
expose_php	off
date.timezone	UTC

Installer scripts

The installer scripts within this container are meant as a starting point for usage in local development images or with Docker multi builds. Usage within production images is not recommended.

Install Composer

Run /usr/local/bin/install_composer.sh to download the official Composer install script. It is stored in /etc/composer/ together with the installer's signature. The install_composer.sh script will check if the signature matches and executes the installer. The Composer executable is moved to /usr/local/bin/ and is ready to be used.

Make sure to add /root/.composer/vendor/bin to your PATH if you'd like to make use of binaries from global packages.

Install devkit tools

After installing Composer it is possible to install some default devkit tools. Run /usr/local/bin/install_devkit.sh to globally install phploc, phpstan and phpcs.

Install Xdebug

Run /usr/local/bin/install_xdebug.sh to compile xdebug and install the module. It will then copy a default xdebug.ini config file to /config/php/xdebug.ini where you can change the settings to your needs.
