Parameters

Parameter	Comments
access_key aliases: aws_access_key_id, aws_access_key, ec2_access_key string	AWS access key ID. See the AWS documentation for more information about access tokens https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys. The AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variables may also be used in decreasing order of preference. The aws_access_key and profile options are mutually exclusive. The aws_access_key_id alias was added in release 5.1.0 for consistency with the AWS botocore SDK. The ec2_access_key alias has been deprecated and will be removed in a release after 2024-12-01. Support for the EC2_ACCESS_KEY environment variable has been deprecated and will be removed in a release after 2024-12-01.
aws_ca_bundle path	The location of a CA Bundle to use when validating SSL certificates. The AWS_CA_BUNDLE environment variable may also be used.
aws_config dictionary	A dictionary to modify the botocore configuration. Parameters can be found in the AWS documentation https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html#botocore.config.Config.
debug_botocore_endpoint_logs boolean	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. Choices: false ← (default) true
dry_run boolean	Do not *actually* invoke the function. A DryRun call will check that the caller has permissions to call the function, especially for checking cross-account permissions. Choices: false ← (default) true
endpoint_url aliases: ec2_url, aws_endpoint_url, s3_url string	URL to connect to instead of the default AWS endpoints. While this can be used to connection to other AWS-compatible services the amazon.aws and community.aws collections are only tested against AWS. The AWS_URL or EC2_URL environment variables may also be used, in decreasing order of preference. The ec2_url and s3_url aliases have been deprecated and will be removed in a release after 2024-12-01. Support for the EC2_URL environment variable has been deprecated and will be removed in a release after 2024-12-01.
function_arn string	The name of the function to be invoked
name string	The name of the function to be invoked. This can only be used for invocations within the calling account. To invoke a function in another account, use function_arn to specify the full ARN.
payload dictionary	A dictionary in any form to be provided as input to the Lambda function. Default: {}
profile aliases: aws_profile string	A named AWS profile to use for authentication. See the AWS documentation for more information about named profiles https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-profiles.html. The AWS_PROFILE environment variable may also be used. The profile option is mutually exclusive with the aws_access_key, aws_secret_key and security_token options.
region aliases: aws_region, ec2_region string	The AWS region to use. For global services such as IAM, Route53 and CloudFront, region is ignored. The AWS_REGION or EC2_REGION environment variables may also be used. See the Amazon AWS documentation for more information http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region. The ec2_region alias has been deprecated and will be removed in a release after 2024-12-01 Support for the EC2_REGION environment variable has been deprecated and will be removed in a release after 2024-12-01.
secret_key aliases: aws_secret_access_key, aws_secret_key, ec2_secret_key string	AWS secret access key. See the AWS documentation for more information about access tokens https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys. The AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variables may also be used in decreasing order of preference. The secret_key and profile options are mutually exclusive. The aws_secret_access_key alias was added in release 5.1.0 for consistency with the AWS botocore SDK. The ec2_secret_key alias has been deprecated and will be removed in a release after 2024-12-01. Support for the EC2_SECRET_KEY environment variable has been deprecated and will be removed in a release after 2024-12-01.
session_token aliases: aws_session_token, security_token, aws_security_token, access_token string	AWS STS session token for use with temporary credentials. See the AWS documentation for more information about access tokens https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys. The AWS_SESSION_TOKEN, AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variables may also be used in decreasing order of preference. The security_token and profile options are mutually exclusive. Aliases aws_session_token and session_token were added in release 3.2.0, with the parameter being renamed from security_token to session_token in release 6.0.0. The security_token, aws_security_token, and access_token aliases have been deprecated and will be removed in a release after 2024-12-01. Support for the EC2_SECRET_KEY and AWS_SECURITY_TOKEN environment variables has been deprecated and will be removed in a release after 2024-12-01.
tail_log boolean	If tail_log=true, the result of the task will include the last 4 KB of the CloudWatch log for the function execution. Log tailing only works if you use synchronous invocation wait=true. This is usually used for development or testing Lambdas. Choices: false ← (default) true
validate_certs boolean	When set to false, SSL certificates will not be validated for communication with the AWS APIs. Setting validate_certs=false is strongly discouraged, as an alternative, consider setting aws_ca_bundle instead. Choices: false true ← (default)
version_qualifier string	Which version/alias of the function to run. This defaults to the LATEST revision, but can be set to any existing version or alias. See https://docs.aws.amazon.com/lambda/latest/dg/versioning-aliases.html for details.
wait boolean	Whether to wait for the function results or not. If wait=no the task will not return any results. To wait for the Lambda function to complete, set wait=true and the result will be available in the output key. Choices: false true ← (default)

Notes

Note

• Async invocation will always return an empty result.output key.

• Synchronous invocation may result in a function timeout, resulting in an empty result.output key.

• 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.

Examples

- amazon.aws.lambda_execute:
    name: test-function
    # the payload is automatically serialized and sent to the function
    payload:
      foo: bar
      value: 8
  register: response

# Test that you have sufficient permissions to execute a Lambda function in
# another account
- amazon.aws.lambda_execute:

    dry_run: true

- amazon.aws.lambda_execute:
    name: test-function
    payload:
      foo: bar
      value: 8
    wait: true
    tail_log: true
  register: response
  # the response will have a `logs` key that will contain a log (up to 4KB) of the function execution in Lambda

# Pass the Lambda event payload as a json file.
- amazon.aws.lambda_execute:
    name: test-function
    payload: "{{ lookup('file','lambda_event.json') }}"
  register: response
