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, lambda_invoke to execute a lambda function and lambda_facts to gather facts 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	Default: None	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	Default: None	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
ec2_url	Default: None	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 (added in 1.6)	Default: None	Uses a boto profile. Only works with boto >= 2.24.0.
region		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 (added in 1.6)	Default: None	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 required	Choices: present ← absent	Describes the desired state.
statement_id required		A unique statement identifier. aliases: sid
validate_certs (added in 1.5)	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 http://boto.readthedocs.org/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

Key	Returned	Description
lambda_policy_action string	success	describes what action was taken
