The way I (total n00b) got my Flask App Working with Heroku

• Set up a github repo
• Create a procfile
• Make sure that gunicorn and all your requirements are in a requirements.txt file

$ pip install gunicorn
$ pip freeze > requirements.txt

• Specify a Python version so that Heroku uses the right one to run our app by set runtime.txt for the version of python you're using

python-3.4.2

• Push everything to github when you're ready

$ heroku create YOUR_PRODUCTION_APP
$ heroku create YOUR_STAGING_APP

$ git remote add pro [email protected]:YOUR_PRODUCTION_APP.git
$ git remote add stage [email protected]:YOUR_STAGING_APP.git

Databases

$ heroku addons:create heroku-postgresql:hobby-dev --app YOUR_STAGING_APP
  Adding heroku-postgresql:dev on wordcount-stage... done, v8 (free)
  Attached as HEROKU_POSTGRESQL_AMBER_URL
  Database has been created and is available
   ! This database is empty. If upgrading, you can transfer
   ! data from another database with pgbackups:restore.
