    And my docker compose file is

        build: ./.config/etc/nginx/
            - 7000:80
            - php
            - memcached:memcached            
            - app
      image: memcached:latest   
        build: ./.config/etc/php/
            - 9000
            - mysql
            - memcached:memcached            
            - app
        image: php:5.6-fpm
        #image: php:7.0-fpm
            - ./:/var/www/vhosts/
        command: "true"

    The error i am getting on the code is

    [36;1mnginx_1 | [0mPHP message: PHP Fatal error: Class ‘memcache’ not found in Unknown on line 0″ while reading response header from upstream, client:, server:, request: “GET /search HTTP/1.1”, upstream: “fastcgi://”, host: “”

    Any ideas on what is going wrong here ?

    The php images ship a custom-compiled PHP, but are based on a Debian Jessie image (and use Debian’s repositories). With apt-get install php5-memcached, you install the memcached extension for the distribution’s PHP package (which is installed along the way).

    You need to install the memcached extension via PECL (and its build dependencies via APT):

    RUN apt-get update
    RUN apt-get install -y libz-dev libmemcached-dev && \
        pecl install memcached && \
        docker-php-ext-enable memcached
    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
