How can a Flask application be executed?1 pointpython app.jsruby app.rbphp app.phpflask run
Solution
To execute a Flask application, you can follow these steps:
-
First, you need to set the FLASK_APP environment variable to the name of your Flask application file. For example, if your Flask application file is named
app.py, you would set the FLASK_APP environment variable like this:On Unix/Linux:
export FLASK_APP=app.pyOn Windows:
set FLASK_APP=app.py -
Once the FLASK_APP environment variable is set, you can run your Flask application using the
flask runcommand:flask run

Now that you have your development environment set up, let’s get your production application server set up with Gunicorn on web-01, port 5000. You’ll need to install Gunicorn and any libraries required by your application. Your Flask application object will serve as a WSGI entry point into your application. This will be your production environment. As you can see we want the production and development of your application to use the same port, so the conditions for serving your dynamic content are the same in both environments.Requirements:Install Gunicorn and any other libraries required by your application.The Flask application object should be called app. (This will allow us to run and check your code)You will serve the same content from the same route as in the previous task. You can verify that it’s working by binding a Gunicorn instance to localhost listening on port 5000 with your application object as the entry point.In order to check your code, the checker will bind a Gunicorn instance to port 6000, so make sure nothing is listening on that port.Example:Terminal 1:ubuntu@229-web-01:~/AirBnB_clone_v2$ gunicorn --bind 0.0.0.0:5000 web_flask.0-hello_route:app[2019-05-03 20:47:20 +0000] [3595] [INFO] Starting gunicorn 19.9.0[2019-05-03 20:47:20 +0000] [3595] [INFO] Listening at: http://0.0.0.0:5000 (3595)[2019-05-03 20:47:20 +0000] [3595] [INFO] Using worker: sync[2019-05-03 20:47:20 +0000] [3598] [INFO] Booting worker with pid: 3598Terminal 2:ubuntu@229-web-01:~$ curl 127.0.0.1:5000/airbnb-onepage/Hello HBNB!ubuntu@229-web-01:~$
