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.
