Just PHP 7 with Memcached-Client
This Docker-Image is based on php:7.2-fpm plus the memcached-client by installing libmemcached-dev as well as memcached-3.0.3.
docker run -P -v <local-store>:/var/www mheindl/php7-memcached-client <command, like "php --version">
If you are develop an application like an Laravel Lumen API and on deployment want to use commands like
php artisan cache:clear
you need PHP and the Class "Memcached", otherwise you will end up in an Error like
$ php artisan cache:clear [Symfony\Component\Debug\Exception\FatalThrowableError] Class 'Memcached' not found
