title: How to create stack in tutum with docker-compose.yml file?
body: <p>I am trying to build a Stack as follows:</p>
  
  <pre><code>redis:
    image: redis
    ports:
      - '6379'
  app:
    build: .
    links:
      - redis
  </code></pre>
  
  <p>when I push "Create Stack" button, I get this error:</p>
  
  <pre><code>Oops!
  
  Service 'app': Value {u'build': u'.', u'links': [u'redis'], u'name': u'app'} for field '&lt;obj&gt;' contains additional property 'build' not defined by 'properties' or 'patternProperties' and additionalProperties is False. See 'https://support.tutum.co/support/solutions/articles/5000583471' for more details
  </code></pre>
  
  <p>Can someone help me with this please?</p>
