Notes
-----

.. note::
   - This module heavily depends on :ref:`community.aws.lambda_policy <community.aws.lambda_policy_module>` as you need to allow ``lambda:InvokeFunction`` permission for your lambda function.
   - If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence ``AWS_URL`` or ``EC2_URL``, ``AWS_ACCESS_KEY_ID`` or ``AWS_ACCESS_KEY`` or ``EC2_ACCESS_KEY``, ``AWS_SECRET_ACCESS_KEY`` or ``AWS_SECRET_KEY`` or ``EC2_SECRET_KEY``, ``AWS_SECURITY_TOKEN`` or ``EC2_SECURITY_TOKEN``, ``AWS_REGION`` or ``EC2_REGION``
   - Ansible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html
   - ``AWS_REGION`` or ``EC2_REGION`` can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file



Examples
--------

.. code-block:: yaml+jinja

    
    ---
    # Example that creates a lambda event notification for a bucket
    - name: Process jpg image
      community.aws.s3_bucket_notification:
        state: present
        event_name: on_file_add_or_remove
        bucket_name: test-bucket
        function_name: arn:aws:lambda:us-east-2:526810320200:function:test-lambda
        events: ["s3:ObjectCreated:*", "s3:ObjectRemoved:*"]
        prefix: images/
        suffix: .jpg




Return Values
-------------
Common return values are documented `here <https://docs.ansible.com/ansible/latest/reference_appendices/common_return_values.html#common-return-values>`_, the following are the fields unique to this module:

.. raw:: html
