Event Target for AWS Lambda

This event Target receives CloudEvents over HTTP and invokes an AWS Lambda function.

Prerequisite(s)

• AWS API key and secret
• ARN for the Lambda to invoke

Consult the Secrets guide for more information about how to add the AWS API specific secrets.

Deploying an Instance of the Target

Open the Bridge creation screen and add a Target of type AWS Lambda.

In the Target creation form, provide a name for the event Target and add the following information:

• AWS Secret: Reference a TriggerMesh secret containing an AWS API key and Secret as discussed in the prerequisites.
• AWS ARN: The ARN that points to the AWS Lambda function to invoke

There is an optional toggle flag indicating if the full CloudEvent should be sent to the lambda function. By default, this is disabled which means only the event payload will be sent.

After clicking the Save button, the console will self-navigate to the Bridge editor. Proceed by adding the remaining components to the Bridge.

After submitting the Bridge, and allowing for some configuration time, a green check mark on the main Bridges page indicates that the Bridge with the AWS Lambda Target was successfully created.

For more information about using AWS Lambda, please refer to the AWS documentation.

Event Types

The AWS Lambda event Target leaves the CloudEvent type definition to the discretion of the implementer given the flexible nature of AWS Lambda.

However, the response CloudEvent would have the following payload:

Name	Value	Description
ce-type	io.triggermesh.targets.aws.lambda.result	Denotes a response payload from the Lambda function
ce-source	arn:aws:lambda:...	The Lambda's ARN value as configured by the target
body	JSON	A JSON response from the Target invocation
