title: Docker: Sharing a volume on Windows with Docker Toolbox
body: <p>I'm trying to setup a developer environment through a Docker container on my Windows&nbsp;7 computer.</p>
  
  <p>I've installed Docker toolbox for Windows.</p>
  
  <p>I have an image with Apache and PHP 5.6 within, and here it is:</p>
  
  <pre><code>FROM php:5.6.15-apache
  
  RUN apt-get update &amp;&amp; apt-get install -y \
  apt-utils vim git php5-mysql php5-memcache php5-memcached php5-intl \
  wget
  RUN apt-get install libapache2-mod-php5 -y -o Dpkg::Options::="--force-confdef"
  RUN docker-php-ext-install mbstring
  RUN docker-php-ext-install pdo pdo_mysql
  RUN apt-get install libcurl4-gnutls-dev -y
  RUN docker-php-ext-install curl
  RUN a2enmod rewrite
  
  ENV APACHE_RUN_USER myname
  ENV APACHE_RUN_GROUP www-data
  ENV APACHE_LOG_DIR /var/log/apache2
  ENV APACHE_LOCK_DIR /var/lock/apache2
  ENV APACHE_PID_FILE /var/run/apache2.pid
  
  EXPOSE 80
  
  COPY php.ini /usr/local/etc/php/php.ini
  COPY apache-config.conf /etc/apache2/sites-enabled/000-default.conf
  RUN echo "ServerName 127.0.1.1" &gt;&gt; /etc/apache2/apache2.conf
  </code></pre>
  
  <p>This image is created, and I can see it when I run "docker images" in the Docker quickstart terminal.</p>
  
  <p>In my apache-config.conf, I just have a tiny virtual host to access a test website with just an index.php file.</p>
  
  <p>Then I try to create the container in the Docker quickstart terminal:</p>
  
  <pre><code>docker run --name=php5.6_container --rm -v "//c/sites:/var/www/html" -p 80:80 -p 8080:8080 php5.6
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>AH00112: Warning: DocumentRoot [/var/www/html/test] does not exist
  AH00112: Warning: DocumentRoot [/var/www/html/test] does not exist
  [Tue Dec 08 16:36:37.703143 2015] [mpm_prefork:notice] [pid 1] AH00163: Apache/2.4.10 (Debian) configured -- resuming normal operations
  [Tue Dec 08 16:36:37.703733 2015] [core:notice] [pid 1] AH00094: Command line: '
  apache2 -D FOREGROUND'
  </code></pre>
  
  <p>It seems like my volume option is not taken into account. And the container is not created.</p>
  
  <p>What could I be doing wrong?</p>
