Docker - How to disable PHP ext / modules

I am working on a PHP API and I would like to disable unused php Modules inside my PHP-FPM image, such as "sqlite3, pdo ..".

I am a docker beginner and I would like to know if is there anything similar to docker-php-ext-enable if not what is the best practice for disabling unused php modules.

Solution

  • Finally I found the key point.

    Inside docker php container, all the registered modules holds by a configuration file under the below path.

    /usr/local/etc/php/conf.d/*.ini

    bash into the container:

    docker exec -it php_container_name bash

    You can list all the enabled modules by php -m:

    And cd into that folder, you can see the relating config files:

    cd /usr/local/etc/php/conf.d/
ls

# output
docker-php-ext-mcrypt.ini  docker-php-ext-mysqli.ini    
docker-php-ext-opcache.ini  opcache-recommended.ini  
docker-php-ext-zip.ini

    To disable some extension module, make a dir disabled, and move that .ini file inside it, for example:

    mkdir disabled
mv docker-php-ext-opcache.ini disabled
mv opcache-recommended.ini

    Finally, press Ctrl+D to exit the container, and then restart the container to make changes work.

    docker restart php_container_name

    You can get into the container and run php -m to see, the relating extension is gone.
