Deploying Python Applications on Heroku

1. Add control / metadata files
   • app.json

     {
      "name": "NAME",
      "description": "DESCRIPTION",
      "repository": "HTTP_PATH_TO_REPO",
      "logo": "HTTP_PATH_TO_LOGO",
      "keywords": [ "KEYWORD1", "KEYWORD2"]
     }
     

   • Profile

     web: gunicorn WSGI_CLASS_TO_LOAD:app
     

   • update requirements.txt to add

     gunicorn
     

   • runtime.txt

     python-3.8.3
     

     git commit -am 'add Heroku files'
     

2. Log into Heroku

   heroku login
   

3. Create your Heroku application

   heroku create APP_NAME
   

4. Push your branch (if master you can just use ‘heroku master’) for deployment

   git push heroku BRANCH:master
