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
# 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 <>`_ 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"}``
