preparation

Before deploying to Azure, az login is required.

$ az login

You have logged in. Now let us find all the subscriptions to which you have access...

Quickstart

In your project directory, type below. Directory {function_app_name} and example python scripts are created.

$ paten new-app {function_app_name}

Then, modify app.py, like below.

import azure.functions as func
from paten import Paten

app = Paten('{function_app_name}')


@app.http_trigger('req', methods=['GET'], route='/')
@app.out_http()
def example_http_function(req: func.HttpRequest) -> func.HttpResponse:
    name = req.params.get('name')
    
    # response
    return func.HttpResponse(name)

Before deploying to azure functions, you can test your functions on local with the command below.

$ paten local

Finally, to deploy to azure functions, type below in the directory {function_app_name}. The files are generated in ./{function_app_name}/.paten and your function app is deployed to azure.

$ paten deploy
