In the `php` dockerhub image, we can do the following: ``` docker-php-ext-install -j$(nproc) iconv mcrypt \ && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \ && docker-php-ext-install -j$(nproc) gd ``` Is there a similar way in this base image to do the same as we need a zend application to have mcrypt installed.
