community.aws.execute_lambda module – Execute an AWS Lambda function

Note

This module is part of the community.aws collection (version 2.6.1).

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 community.aws.

To use it in a playbook, specify: community.aws.execute_lambda.

New in version 1.0.0: of community.aws

Synopsis 

This module executes AWS Lambda functions, allowing synchronous and asynchronous invocation.

Requirements 

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

python >= 3.6
boto3 >= 1.15.0
botocore >= 1.18.0

Parameters 

Parameter	Comments
aws_access_key aliases: ec2_access_key, 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. If profile is set this parameter is ignored. Passing the aws_access_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.
aws_ca_bundle path	The location of a CA Bundle to use when validating SSL certificates. Not used by boto 2 based modules. Note: The CA Bundle is read ‘module’ side and may need to be explicitly copied from the controller if not run locally.
aws_config dictionary	A dictionary to modify the botocore configuration. Parameters can be found at https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html#botocore.config.Config. Only the ‘user_agent’ key is used for boto modules. See http://boto.cloudhackers.com/en/latest/boto_config_tut.html#boto for more boto configuration.
aws_secret_key aliases: ec2_secret_key, 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. If profile is set this parameter is ignored. Passing the aws_secret_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.
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: no ← (default) yes
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: no ← (default) yes
ec2_url aliases: aws_endpoint_url, endpoint_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.
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	Using profile will override aws_access_key, aws_secret_key and security_token and support for passing them at the same time as profile has been deprecated. aws_access_key, aws_secret_key and security_token will be made mutually exclusive with profile after 2022-06-01.
region aliases: aws_region, ec2_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
security_token aliases: aws_security_token, access_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. If profile is set this parameter is ignored. Passing the security_token and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.
tail_log boolean	If tail_log=yes, 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=yes. This is usually used for development or testing Lambdas. Choices: no ← (default) yes
validate_certs boolean	When set to “no”, SSL certificates will not be validated for communication with the AWS APIs. Choices: no yes ← (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=yes and the result will be available in the output key. Choices: no yes ← (default)

Notes 

Note

Async invocation will always return an empty output key.
Synchronous invocation may result in a function timeout, resulting in an empty output key.
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_PROFILE or AWS_DEFAULT_PROFILE, 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, AWS_CA_BUNDLE
When no credentials are explicitly provided the AWS SDK (boto3) that Ansible uses will fall back to its configuration files (typically ~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.
Modules based on the original AWS SDK (boto) may read their default configuration from different files. See https://boto.readthedocs.io/en/latest/boto_config_tut.html for more information.
AWS_REGION or EC2_REGION can be typically be used to specify the AWS region, when required, but this can also be defined in the configuration files.

Return Values 

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

Key	Description
result dictionary	Resulting data structure from a successful task execution. Returned: success
logs string	The last 4KB of the function logs. Only provided if tail_log is `true` Returned: if tail_log == true
output dictionary	Function output if wait=true and the function returns a value Returned: success Sample: “{ \u0027output\u0027: \u0027something\u0027 }”
status integer	`StatusCode` of API call exit (200 for synchronous invokes, 202 for async) Returned: always Sample: 200
