amazon.aws.lambda_event module – Creates, updates or deletes AWS Lambda function event mappings
Note
This module is part of the amazon.aws collection (version 9.1.0).
You might already have this collection installed if you are using the ansible package.
It is not included in ansible-core.
To check whether it is installed, run ansible-galaxy collection list.
To install it, use: ansible-galaxy collection install amazon.aws.
You need further requirements to be able to use this module,
see Requirements for details.
To use it in a playbook, specify: amazon.aws.lambda_event.
New in amazon.aws 5.0.0
Synopsis
This module allows the management of AWS Lambda function event source mappings such as DynamoDB and Kinesis stream events via the Ansible framework. These event source mappings are relevant only in the AWS Lambda pull model, where AWS Lambda invokes the function. It is idempotent and supports “Check” mode. Use module amazon.aws.lambda to manage the lambda function itself and amazon.aws.lambda_alias to manage function aliases.
This module was originally added to
community.awsin release 1.0.0.
Requirements
The below requirements are needed on the host that executes this module.
python >= 3.6
boto3 >= 1.28.0
botocore >= 1.31.0

Notes
Note
Caution: For modules, environment variables and configuration files are read from the Ansible ‘host’ context and not the ‘controller’ context. As such, files may need to be explicitly copied to the ‘host’. For lookup and connection plugins, environment variables and configuration files are read from the Ansible ‘controller’ context and not the ‘host’ context.
The AWS SDK (boto3) that Ansible uses may also read defaults for credentials and other settings, such as the region, from its configuration files in the Ansible ‘host’ context (typically
~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.
