## Synopsis

- This module allows the management of AWS Lambda function bucket event mappings via the Ansible framework. Use module lambda to manage the lambda function itself, lambda_alias to manage function aliases and lambda_policy to modify lambda permissions.

## Requirements

The below requirements are needed on the host that executes this module.

- boto

- boto3

- python >= 2.6

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
aws_access_key string |  | AWS access key. If not set then the value of the AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variable is used. aliases: ec2_access_key, access_key
aws_secret_key string |  | AWS secret key. If not set then the value of the AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variable is used. aliases: ec2_secret_key, secret_key
bucket_name string / required |  | S3 bucket name
debug_botocore_endpoint_logs boolean added in 2.8 | Choices: no ← yes | Use a botocore.endpoint logger to parse the unique (rather than total) "resource:action" API calls made during a task, outputing the set to the resource_actions key in the task results. Use the aws_resource_action callback to output to total list made during a playbook. The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used.
ec2_url string |  | Url to use to connect to EC2 or your Eucalyptus cloud (by default the module will use EC2 endpoints). Ignored for modules where region is required. Must be specified for all other modules if region is not used. If not set then the value of the EC2_URL environment variable, if any, is used.
event_name string / required |  | unique name for event notification on bucket
events list / required | Choices: s3:ObjectCreated:* s3:ObjectCreated:Put s3:ObjectCreated:Post s3:ObjectCreated:Copy s3:ObjectCreated:CompleteMultipartUpload s3:ObjectRemoved:* s3:ObjectRemoved:Delete s3:ObjectRemoved:DeleteMarkerCreated s3:ObjectRestore:Post s3:ObjectRestore:Completed s3:ReducedRedundancyLostObject | Events that you want to be triggering notifications. You can select multiple events to send to the same destination, you can set up different events to send to different destinations, and you can set up a prefix or suffix for an event. However, for each bucket, individual events cannot have multiple configurations with overlapping prefixes or suffixes that could match the same object key.
lambda_alias string |  | Name of the Lambda function alias. Mutually exclusive with `lambda_version`.
lambda_function_arn string |  | The ARN of the lambda function. aliases: function_arn
lambda_version integer |  | Version of the Lambda function. Mutually exclusive with `lambda_alias`.
prefix string |  | Optional prefix to limit the notifications to objects with keys that start with matching characters.
profile string |  | Uses a boto profile. Only works with boto >= 2.24.0.
region string |  | The AWS region to use. If not specified then the value of the AWS_REGION or EC2_REGION environment variable, if any, is used. See http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region aliases: aws_region, ec2_region
security_token string |  | AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used. aliases: access_token
state string / required | Choices: present ← absent | Describes the desired state.
suffix string |  | Optional suffix to limit the notifications to objects with keys that end with matching characters.
validate_certs boolean | Choices: no yes ← | When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

## Notes

Note

- This module heavily depends on lambda_policy 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

    ---
    # Example that creates a lambda event notification for a bucket
    - hosts: localhost
      gather_facts: no
      tasks:
      - name: Process jpg image
        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

Key | Returned | Description
