Notes
|
|
-----
|
|
|
|
.. note::
|
|
- Async invocation will always return an empty ``output`` key.
|
|
- Synchronous invocation may result in a function timeout, resulting in an empty ``output`` key.
|
|
- 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``
|
|
- When no credentials are explicitly provided the AWS SDK (boto3) that Ansible uses will fall back to its configuration files (typically ``~/.aws/credentials``). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.
|
|
- Modules based on the original AWS SDK (boto) may read their default configuration from different files. See https://boto.readthedocs.io/en/latest/boto_config_tut.html for more information.
|
|
- ``AWS_REGION`` or ``EC2_REGION`` can be typically be used to specify the AWS region, when required, but this can also be defined in the configuration files.
|
|
|
|
|
|
