Google Cloud Storage Transfer Operator to SFTP
==============================================

Google has a service `Google Cloud Storage <https://cloud.google.com/storage/>`__.
This service is used to store large data from various applications.
SFTP (SSH File Transfer Protocol) is a secure file transfer protocol.
It runs over the SSH protocol. It supports the full security and authentication functionality of SSH.

Prerequisite Tasks

Operator
^^^^^^^^

Transfer files between SFTP and Google Storage is performed with the
:class:`~airflow.providers.google.cloud.transfers.gcs_to_sftp.GCSToSFTPOperator` operator.

Use :ref:`Jinja templating <concepts:jinja-templating>` with
:template-fields:`airflow.providers.google.cloud.transfers.gcs_to_sftp.GCSToSFTPOperator`
to define values dynamically.


Copying a single file
---------------------

The following Operator copies a single file.

.. exampleinclude:: /../../tests/system/providers/google/cloud/transfers/example_gcs_to_sftp.py
    :language: python
    :dedent: 4
    :start-after: [START howto_operator_gcs_to_sftp_copy_single_file]
    :end-before: [END howto_operator_gcs_to_sftp_copy_single_file]

Moving a single file
--------------------

To move the file use the ``move_object`` parameter. Once the file is copied to SFTP,
the original file from the Google Storage is deleted. The ``destination_path`` parameter defines the
full path of the file on the SFTP server.

.. exampleinclude:: /../../tests/system/providers/google/cloud/transfers/example_gcs_to_sftp.py
    :language: python
    :dedent: 4
    :start-after: [START howto_operator_gcs_to_sftp_move_single_file_destination]
    :end-before: [END howto_operator_gcs_to_sftp_move_single_file_destination]


Copying a directory
-------------------

Use the ``wildcard`` in ``source_path`` parameter to copy a directory.

.. exampleinclude:: /../../tests/system/providers/google/cloud/transfers/example_gcs_to_sftp.py
    :language: python
    :dedent: 4
    :start-after: [START howto_operator_gcs_to_sftp_copy_directory]
    :end-before: [END howto_operator_gcs_to_sftp_copy_directory]

Moving specific files
---------------------

Use the ``wildcard`` in ``source_path`` parameter to move the specific files.
The ``destination_path`` defines the path that is prefixed to all copied files.

.. exampleinclude:: /../../tests/system/providers/google/cloud/transfers/example_gcs_to_sftp.py
    :language: python
    :dedent: 4
    :start-after: [START howto_operator_gcs_to_sftp_move_specific_files]
    :end-before: [END howto_operator_gcs_to_sftp_move_specific_files]
