Complexity Analysis and Rating - Chart Parameters

airflowLocalSettings

airflow_local_settings file as a string (templated). You can bake an airflow_local_settings.py into your image instead. In that case, set this value to null.

See values.yaml

keep

airflowVersion

Airflow version (Used to make some decisions based on Airflow Version being deployed).

3.1.7

keep

apiSecretAnnotations

Annotations to add to the Api secret.

{}

Description remains from v2 terms. 

apiSecretKey

The Flask secret key for Airflow Api to encrypt browser session.

~

Description remains from v2 terms. 

apiServer.apiServerConfig

This string (templated) will be mounted into the Airflow API Server as a custom webserver_config.py. You can bake a webserver_config.py in to your image instead or specify a configmap containing the webserver_config.py.

~

Examples:

apiServerConfig: |-
  from airflow import configuration as conf

  # The SQLAlchemy connection string.
  SQLALCHEMY_DATABASE_URI = conf.get('database', 'SQL_ALCHEMY_CONN')

  # Flask-WTF flag for CSRF
  CSRF_ENABLED = True

This is still relevant if the user is using providers-fab and adding more fine-grained authentication integration through fab. That also generalised to BaseAuthManager and to providers that implement 3rd-party libraries and tools. I think the description should be updated.
