Configuration Reference
.......................

This page contains the list of all the available Airflow configurations that you
can set in ``airflow.cfg`` file or using environment variables.

Use the same configuration across all the Airflow components. While each component
does not require all, some configurations need to be same otherwise they would not
work as expected. A good example for that is :ref:`secret_key<config:api__secret_key>` which
should be same on the Webserver and Worker to allow Webserver to fetch logs from Worker.

The webserver key is also used to authorize requests to Celery workers when logs are retrieved. The token
generated using the secret key has a short expiry time though - make sure that time on ALL the machines
that you run Airflow components on is synchronized (for example using ntpd) otherwise you might get
"forbidden" errors when the logs are accessed.

.. note::
    For more information see :doc:`/howto/set-config`.


Provider-specific configuration options
---------------------------------------

Some of the providers have their own configuration options, you will find details of their configuration
in the provider's documentation.

You can find all the provider configuration in
:doc:`configurations specific to providers <apache-airflow-providers:core-extensions/configurations>`
