execute_lambda – Execute an AWS Lambda function¶
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 |
|
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
|
|
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
|
|
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
|
|
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
|
|
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
orEC2_URL
,AWS_ACCESS_KEY_ID
orAWS_ACCESS_KEY
orEC2_ACCESS_KEY
,AWS_SECRET_ACCESS_KEY
orAWS_SECRET_KEY
orEC2_SECRET_KEY
,AWS_SECURITY_TOKEN
orEC2_SECURITY_TOKEN
,AWS_REGION
orEC2_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
orEC2_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
# Pass the Lambda event payload as a json file.
- execute_lambda:
name: test-function
payload: "{{ lookup('file','lambda_event.json') }}"
register: response
- execute_lambda:
name: test-function
version_qualifier: PRODUCTION
