Configuring Airflow
-------------------

The chart allows for setting arbitrary Airflow configuration in values under the ``config`` key.
Some of the defaults in the chart differ from those of core Airflow and can be found in
`values.yaml <https://github.com/apache/airflow/blob/main/chart/values.yaml>`__.

As an example of setting arbitrary configuration, the following yaml demonstrates how one would
allow webserver users to view the config from within the UI:

.. code-block:: yaml

   config:
     webserver:
       expose_config: 'True'  # by default this is 'False'

Generally speaking, it is useful to familiarize oneself with the Airflow
configuration prior to installing and deploying the service.

.. note::

  The recommended way to load example DAGs using the official Docker image and chart is to configure the ``AIRFLOW__CORE__LOAD_EXAMPLES`` environment variable
  in ``extraEnv`` (see :doc:`Parameters reference <parameters-ref>`). The official Docker image has ``AIRFLOW__CORE__LOAD_EXAMPLES=False``
  set within the image, so you need to override it with an environment variable when deploying the chart in order for the examples to be present.

.. note::

  The  ``AIRFLOW__CORE__LOAD_DEFAULT_CONNECTIONS`` variable is not used by the Chart. Airflow Helm Chart is
  intended to be used as production deployment and loading default connections is not supposed to be handled
  during Chart installation. The Chart is intended to install and configure the Apache Airflow software
  and create database structure, but not to fill-in the data which should be managed by the users.
  The default connections are only meaningful when you want to have a ``quick start`` with Airflow or
  do some development and adding the data via Helm Chart installation is not a good idea.
