title: How to deploy GCP App Engine worker?
body: <p>I am trying to make personal apps on GCP- following the deploying a complex Python app to flexible Google Cloud environment tutorial [ <a href="https://cloud.google.com/python/getting-started/using-pub-sub" rel="nofollow noreferrer">https://cloud.google.com/python/getting-started/using-pub-sub</a> ].
  In the 6-pub/sub step- where we learn to use a worker in the backend to do parallel/background tasks: I'm unable to deploy the worker. </p>
  
  <p>I haven't changed the code from the tutorial repo.</p>
