title: Google App Engine: Ruby on Rails - Execute migrations automatically
body: <p>I was wondering if it was possible to run migrations automatically during deployment with Google App Engine. I have been using AWS Elasticbeanstalk for a while and they were ran automatically but now I am considering moving to the Google App Engine for my future projects.</p>
  
  <p>Right now, I must run this command manually: </p>
  
  <pre><code>bundle exec rake appengine:exec -- bundle exec rake db:migrate GAE_CONFIG=app.yml
  </code></pre>
  
  <p>Thank you</p>
