title: Cloudformation: Outputs - Can you return a value from a file
body: <p>Cloudformation appears to have an "Outputs" section where you can have a value referenced for other stacks, or to display back to the user, etc.</p>
  
  <p><a href="http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/outputs-section-structure.html" rel="nofollow noreferrer">The limited doc is here</a>.</p>
  
  <p>Is it possible to use this to make the contents of a file available?</p>
  
  <p>e.g. I've got a Jenkins install where the initial admin password is stored within:</p>
  
  <pre><code>/var/lib/jenkins/secrets/initialAdminPassword
  </code></pre>
  
  <p>I'd love to have that value available after deploying our Jenkins Cloudformation stack without having to then SSH into the server.</p>
  
  <p>Is this possible with the outputs section, or any other way with cloudformation templates?</p>
