## Synopsis

- This module allows the management of AWS Lambda policy statements. It is idempotent and supports “Check” mode. Use module lambda to manage the lambda function itself, lambda_alias to manage function aliases, lambda_event to manage event source mappings such as Kinesis streams, execute_lambda to execute a lambda function and lambda_info to gather information relating to one or more lambda functions.

## Requirements

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

- boto
- boto3
- python >= 2.6

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
action - / required |  | The AWS Lambda action you want to allow in this statement. Each Lambda action is a string starting with lambda: followed by the API name (see Operations ). For example, lambda:CreateFunction . You can use wildcard (lambda:* ) to grant permission for all AWS Lambda actions.
alias - |  | Name of the function alias. Mutually exclusive with `version`.
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
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_source_token - |  | Token string representing source ARN or account. Mutually exclusive with `source_arn` or `source_account`.
function_name - / required |  | Name of the Lambda function whose resource policy you are updating by adding a new permission. You can specify a function name (for example, Thumbnail ) or you can specify Amazon Resource Name (ARN) of the function (for example, arn:aws:lambda:us-west-2:account-id:function:ThumbNail ). AWS Lambda also allows you to specify partial ARN (for example, account-id:Thumbnail ). Note that the length constraint applies only to the ARN. If you specify only the function name, it is limited to 64 character in length. aliases: lambda_function_arn, function_arn
principal - / required |  | The principal who is getting this permission. It can be Amazon S3 service Principal (s3.amazonaws.com ) if you want Amazon S3 to invoke the function, an AWS account ID if you are granting cross-account permission, or any valid AWS service principal such as sns.amazonaws.com . For example, you might want to allow a custom application in another AWS account to push events to AWS Lambda by invoking your function.
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
source_account - |  | The AWS account ID (without a hyphen) of the source owner. For example, if the SourceArn identifies a bucket, then this is the bucket owner's account ID. You can use this additional condition to ensure the bucket you specify is owned by a specific account (it is possible the bucket owner deleted the bucket and some other AWS account created the bucket). You can also use this condition to specify all sources (that is, you don't specify the SourceArn ) owned by a specific account.
source_arn - |  | This is optional; however, when granting Amazon S3 permission to invoke your function, you should specify this field with the bucket Amazon Resource Name (ARN) as its value. This ensures that only events generated from the specified bucket can invoke the function.
state - | Choices: present ← absent | Describes the desired state.
statement_id - / required |  | A unique statement identifier. aliases: sid
validate_certs boolean | Choices: no yes ← | When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
version - |  | Version of the Lambda function. Mutually exclusive with `alias`.

## 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_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

    ---
    - hosts: localhost
      gather_facts: no
      vars:
        state: present
      tasks:
      - name: Lambda S3 event notification
        lambda_policy:
          state: "{{ state | default('present') }}"
          function_name: functionName
          alias: Dev
          statement_id: lambda-s3-myBucket-create-data-log
          action: lambda:InvokeFunction
          principal: s3.amazonaws.com
          source_arn: arn:aws:s3:eu-central-1:123456789012:bucketName
          source_account: 123456789012
        register: lambda_policy_action

      - name: show results
        debug:
          var: lambda_policy_action

## Return Values

Common return values are documented here, the following are the fields unique to this module:

Key | Returned | Description
--- | --- | ---
lambda_policy_action string | success | describes what action was taken

## Status

- This module is not guaranteed to have a backwards compatible interface. [preview]
- This module is maintained by the Ansible Community. [community]
