web:
  commands:
    start: flask run -p $PORT
  locations:
    "/":
      passthru: true

• Using gunicorn + PORT

web:
  commands:
    start: gunicorn -w 4 'app:app'
  locations:
    "/":
      passthru: true

• Using gunicorn + SOCKET (requires unix)

  • source env/bin/activate
  • pip install unix
  • pip freeze

web:
  commands:
    start: gunicorn -w 4 -b unix:$SOCKET 'app:app'
  upstream:
    socket_family: unix
  locations:
    "/":
      passthru: true
