|_    dockerfile
|_    gitpush.sh
|_    Procfile
|_    requirements.txt

from swagger_server import encoder


def main():
    app = connexion.App(__name__, specification_dir='./swagger/')
    app.app.json_encoder = encoder.JSONEncoder
    app.add_api('swagger.yaml', arguments={'title': 'end point'}, pythonic_params=True)
    port = int(os.environ.get("PORT", 5000))
    app.run(host = '0.0.0.0', port=port )


if __name__ == '__main__':
    main()

I found the solution myself which you can use it to deploy in appengine too, change the main content of the file as below :

#!/usr/bin/env python3
import connexion
from swagger_server import encoder

app = connexion.App(__name__, specification_dir='./swagger/')
app.app.json_encoder = encoder.JSONEncoder
app.add_api('swagger.yaml', arguments={'title': 'Docuware end point'}, pythonic_params=True)

if __name__ == '__main__':
    app.run()

content in the Procfile:

web: gunicorn swagger_server.__main__:app

content in requirements.txt :

connexion == 2.6.0
python_dateutil == 2.6.0
setuptools >= 21.0.0
gunicorn

this solution works for deploying in heroku, I removed the main() function and written contents without a function approach.
