title: Error deploying django website on docker through heroku - "Your app does not include a heroku.yml build manifest"
body: <p>I am in the final steps of deploying a django website. It uses docker to run it and I'm finally deploying it through heroku. I run into an error when running &quot;git push heroku master&quot;. I receive &quot;Your app does not include a heroku.yml build manifest. To deploy your app, either create a heroku.yml: <a href="https://devcenter.heroku.com/articles/build-docker-images-heroku-yml%22" rel="nofollow noreferrer">https://devcenter.heroku.com/articles/build-docker-images-heroku-yml&quot;</a>. This is odd as I do in fact have a heroku.yml app.</p>
  <p>heroku.yml</p>
  <pre><code>setup:
      addons:
      - plan: heroku-postgresql
  build:
      docker:
          web: Dockerfile
  release:
      image: web
      command:
          - python manage.py collectstatic --noinput
  run:
      web: gunicorn books.wsgi
  </code></pre>
  <p>The tutorial I am following is using &quot;gunicorn bookstore_project.wsgi&quot; but I used books.wsgi as that is the directory my website is in. Neither worked.</p>
