lambda_event - Creates, updates or deletes AWS Lambda function event mappings.
- This module allows the management of AWS Lambda function event source mappings such as DynamoDB and Kinesis stream events via the Ansible framework. These event source mappings are relevant only in the AWS Lambda pull model, where AWS Lambda invokes the function. It is idempotent and supports “Check” mode. Use module lambda to manage the lambda function itself and lambda_alias to manage function aliases.
The below requirements are needed on the host that executes this module.
Parameter |
Choices/Defaults |
Comments |
alias
required |
|
Name of the function alias. Mutually exclusive with version .
|
aws_access_key
|
|
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
|
|
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
|
|
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
|
|
Source of the event that triggers the lambda function.
|
lambda_function_arn
required |
|
The name or ARN of the lambda function.
aliases: function_name, function_arn
|
profile
(added in 1.6) |
|
Uses a boto profile. Only works with boto >= 2.24.0.
|
region
|
|
aliases: aws_region, ec2_region
|
security_token
(added in 1.6) |
|
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_params
required |
|
Sub-parameters required for event source.
== stream event source ==
source_arn The Amazon Resource Name (ARN) of the Kinesis or DynamoDB stream that is the event source.
enabled Indicates whether AWS Lambda should begin polling the event source. Default is True.
batch_size The largest number of records that AWS Lambda will retrieve from your event source at the time of invoking your function. Default is 100.
starting_position The position in the stream where AWS Lambda should start reading. Choices are TRIM_HORIZON or LATEST.
|
state
required |
Choices:
present ←
- absent
|
Describes the desired state.
|
validate_certs
bool
(added in 1.5) |
|
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 .

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
