You will also gain a holistic understanding of Apache Airflow, its key features, components of Airflow Architecture, Airflow Webserver, and different ways of configuring Airflow Webserver UI. In this article, you will gain information about Airflow Webserver.

Furthermore, Apache Airflow is used to schedule and orchestrate data pipelines or workflows. When using Airflow, you will want to access it and perform some tasks from other tools.

This relieves the employees from doing tasks repetitively. It helps organizations to schedule their tasks so that they are executed when the right time comes. Flask-Login depends upon a function designated as the user_loader to get a User instance given a certain user_id.Ġ2:26 In the next lesson, you’ll define the endpoints for the app and code up the OAuth dance.Airflow is a Task Automation tool. Initialize the client with the client ID. Catch a sqlite3.OperationalError in case the database already exists, in which case you should do nothing. An instance of login_manager will add the session tracking features from Flask-Login.Ġ2:03 Attempt to create the database. Either use one stored in an environment variable or generate a new one. For a simple app, the _name_ dunder value will be fine.Ġ1:46 Also, Flask-Login requires a secret key for encryption. The parameter to the Flask() initializer is the name of the application module. Create setup_env.sh…Ġ1:31 and then execute it. At this point, you should also create a shell script to store the client ID and secret in environment variables. well-known/ endpoint to retrieve the OIDC provider configuration. Finally, import the method to create the database and the User class.Ġ1:01 Retrieve the client ID and secret from environment variables and store them in constants. requests will handle HTTP traffic independent of Flask. And sqlite3 is again needed to communicate with the database.Ġ0:36 A number of imports are needed from flask and flask_login, but we’ll explain them in the code.Ġ0:44 The WebApplicationClient is the class that implements the OAuth 2 flow. This app will use an environment variable instead. Since the client secret is a sensitive value you should not store it with the app.

Create a new file app.py.Ġ0:11 The responses from Google will use JSON, and the json package in the Python standard library translates between JSON objects and Python dictionaries.Ġ0:20 The os module is used to manage environment variables.
