PHP-APC is not included to docker container

Copied from cachethq/cachet#1694

Hi I noticed that Cachet container does not has php-apcu package so if user choose APCu as cache module he would get 500 error.

Debian Sid has php-apcu deb package in official repository so we can just add this package name in Docker file.

Your setup

• I use Docker compose for version 2.2
• Cachet 2.2
• Database Postgres
• PHP 7

Actual behaviour

Cachet not wors and generate 500 error after docker container restart.

[2016-04-07 21:29:18] production.CRITICAL: Symfony\Component\Debug\Exception\FatalThrowableError: Fatal error: Call to undefined function Illuminate\Cache\apc_fetch() in /var/www/html/vendor/laravel/framework/src/Illuminate/Cache/ApcWrapper.php:32

Steps to reproduce

Follow docker-compose installation guide and chose APCu as cache module. Then restart docker container.

Looks like we missed this when we switched to php 7.

Taking a closer look, there is no official Debian sid package for a PHP 7 APCu module. The one linked above is for php5.

Ugh, APC with PHP 7 on Sid is painful. I am likely roll the base image back to Jessie so we can have a vendor package until PHP 7 and APC has better support.
