Notes
-----

.. note::
   - 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_PROFILE`` or ``AWS_DEFAULT_PROFILE``, ``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``, ``AWS_CA_BUNDLE``
   - 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

    # basic pre_task and post_task example
    pre_tasks:
      - name: Instance De-register
        community.aws.elb_instance:
          instance_id: "{{ ansible_ec2_instance_id }}"
          state: absent
        delegate_to: localhost
    roles:
      - myrole
    post_tasks:
      - name: Instance Register
        community.aws.elb_instance:
          instance_id: "{{ ansible_ec2_instance_id }}"
          ec2_elbs: "{{ item }}"
          state: present
        delegate_to: localhost
        loop: "{{ ec2_elbs }}"
