AWS SSM Parameter Store Secrets Backend
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

To enable SSM parameter store, specify :py:class:`~airflow.providers.amazon.aws.secrets.systems_manager.SystemsManagerParameterStoreBackend`
as the ``backend`` in  ``[secrets]`` section of ``airflow.cfg``.

Here is a sample configuration:

.. code-block:: ini

    [secrets]
    backend = airflow.providers.amazon.aws.secrets.systems_manager.SystemsManagerParameterStoreBackend
    backend_kwargs = {"connections_prefix": "/airflow/connections", "variables_prefix": "/airflow/variables", "profile_name": "default"}

Optional lookup
"""""""""""""""

Optionally connections, variables, or config may be looked up exclusive of each other or in any combination.
This will prevent requests being sent to AWS SSM Parameter Store for the excluded type.

If you want to look up some and not others in AWS SSM Parameter Store you may do so by setting the relevant ``*_prefix`` parameter of the ones to be excluded as ``null``.

For example, if you want to set parameter ``connections_prefix`` to ``"/airflow/connections"`` and not look up variables, your configuration file should look like this:

.. code-block:: ini

    [secrets]
    backend = airflow.providers.amazon.aws.secrets.systems_manager.SystemsManagerParameterStoreBackend
    backend_kwargs = {"connections_prefix": "/airflow/connections", "variables_prefix": null, "profile_name": "default"}

Storing and Retrieving Connections
""""""""""""""""""""""""""""""""""

If you have set ``connections_prefix`` as ``/airflow/connections``, then for a connection id of ``smtp_default``,
you would want to store your connection at ``/airflow/connections/smtp_default``.

Optionally you can supply a profile name to reference aws profile, e.g. defined in ``~/.aws/config``.

The value of the SSM parameter must be the :ref:`connection URI representation <generating_connection_uri>`
of the connection object.

Storing and Retrieving Variables
""""""""""""""""""""""""""""""""

If you have set ``variables_prefix`` as ``/airflow/variables``, then for an Variable key of ``hello``,
you would want to store your Variable at ``/airflow/variables/hello``.

Optionally you can supply a profile name to reference aws profile, e.g. defined in ``~/.aws/config``.
