Writing logs to Amazon S3
-------------------------

Remote logging to Amazon S3 uses an existing Airflow connection to read or write logs. If you
don't have a connection properly setup, this process will fail.


Enabling remote logging
'''''''''''''''''''''''

To enable this feature, ``airflow.cfg`` must be configured as follows:

.. code-block:: ini

    [logging]
    # Airflow can store logs remotely in AWS S3. Users must supply a remote
    # location URL (starting with either 's3://...') and an Airflow connection
    # id that provides access to the storage location.
    remote_logging = True
    remote_base_log_folder = s3://my-bucket/path/to/logs
    remote_log_conn_id = MyS3Conn
    # Use server-side encryption for logs stored in S3
    encrypt_s3_logs = False

In the above example, Airflow will try to use ``S3Hook('MyS3Conn')``.

You can also use `LocalStack <https://localstack.cloud/>`_ to emulate Amazon S3 locally.
To configure it, you must additionally set the endpoint url to point to your local stack.
You can do this via the Connection Extra ``host`` field.
For example, ``{"host": "http://localstack:4572"}``
