execute_lambda – Execute an AWS Lambda function

New in version 2.2.


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.

  • 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

debug_botocore_endpoint_logs

boolean

added in 2.8

  • 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.

dry_run

boolean

  • no

  • yes

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.

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.

function_arn

-

The name of the function to be invoked

name

-

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

-

Default:

{}

A dictionary in any form to be provided as input to the Lambda 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

tail_log

boolean

  • no

  • yes

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.

validate_certs

boolean

  • no
  • yes

When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

version_qualifier

-

Default:

"LATEST"

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

  • no
  • yes

Whether to wait for the function results or not. If wait is 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.



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_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

- execute_lambda:
    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
- execute_lambda:
    function_arn: arn:aws:lambda:us-east-1:123456789012:function/some-function
    dry_run: true

- execute_lambda:
    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.

- execute_lambda:
    name: test-function
    version_qualifier: PRODUCTION

Return Values

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

Key Returned Description

logs

string

if tail_log == true

The last 4KB of the function logs. Only provided if tail_log is true


output

dictionary

success

Function output if wait=true and the function returns a value


Sample:

{ 'output': 'something' }

status

integer

always

StatusCode of API call exit (200 for synchronous invokes, 202 for async)


Sample:

200
