akilli/php repository overview

⁠akilli/php

akilli/base⁠ based php image.

This images comes with a custom configuration file at /etc/php/conf.d/90_php.ini that is pre-configured for production, amongst others, with

• opcache.jit = 1255,
• opcache.preload = /app/preload.php,
• opcache.validate_timestamps = 0,
• opcache.revalidate_freq = 0 and
• strict sessions.

If you use these default settings, you must provide a preload script at /app/preload.php and be aware of the fact that changes in PHP scripts will only have effect after restarting the server which is perfect for containerized production environment.

Some of these settings are surely not suitable for development. If you set the environment variable DEV=1, the init/10-php⁠ script will enable the dev configuration file⁠ that will effectively disable the session.cookie_secure restriction and opcache and also auto-prepend the preload script at /app/preload.php instead.

Apart from that, there are several possibilities to adjust these default settings. You could p.e.

• completely replace /etc/php/conf.d/90_php.ini with your own ini file,
• append your own ini file p.e. at /etc/php/conf.d/99-zzz.ini to just override selected values,
• use a user ini file .user.ini for certain settings,
• use different fpm pools or
• do something completely different.

You can use the example compose.yml⁠ and compose.override.yml⁠ as a starting point for your configuration.
