lambda_event - Creates, updates or deletes AWS Lambda function event mappings.
New in version 2.2.
Synopsis
- 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.
Requirements
The below requirements are needed on the host that executes this module.
- boto
- boto3
- python >= 2.6
Parameters
Parameter | Choices/Defaults | Comments |
---|---|---|
alias required | Name of the function alias. Mutually exclusive with version . | |
aws_access_key | Default: None | 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 | Default: None | 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 | Default: None | 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) | Default: None | Uses a boto profile. Only works with boto >= 2.24.0. |
region | 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 (added in 1.6) | Default: None | 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 |
| Describes the desired state. |
validate_certs (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 . |
Notes
Note
- 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 http://boto.readthedocs.org/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
--- # Example that creates a lambda event notification for a DynamoDB stream - hosts: localhost gather_facts: no vars: state: present tasks: - name: DynamoDB stream event mapping lambda_event: state: "{{ state | default('present') }}" event_source: stream function_name: "{{ function_name }}" alias: Dev source_params: source_arn: arn:aws:dynamodb:us-east-1:123456789012:table/tableName/stream/2016-03-19T19:51:37.457 enabled: True batch_size: 100 starting_position: TRIM_HORIZON - name: Show source event debug: var: lambda_stream_events
Return Values
Common return values are documented here, the following are the fields unique to this module:
Key | Returned | Description |
---|---|---|
lambda_stream_events list | success | list of dictionaries returned by the API describing stream event mappings |
Status
This module is flagged as preview which means that it is not guaranteed to have a backwards compatible interface.
