title: Ruby On Rails : DOcker : Is it feasible to build ROR project dependencies inside docker image
body: <p>I work on a project built on ROR. This projects has dependent gems and packages such as <code>Fog</code>, <code>rmagick</code>, <code>sidekiq</code>, <code>elasticsearch</code>, <code>carrierwave</code>, <code>imagemagic</code>, <code>engineyard</code>, <code>ruby</code>, <code>rails</code>, etc.   </p>
  
  <p><strong>Problems we faced:</strong><br>
  Frequently laptops of my fellow developers crash. It takes the whole working-day to install all the dependent gems and packages in linux <code>Ubuntu 14.04 / 15.04</code>.</p>
  
  <ul>
  <li>Is it possible to build everything I mentioned above inside a docker image and distribute among the developers?</li>
  <li>Can we run rails like <code>rails s</code>?</li>
  </ul>
