   • Actions supported by this task:

     Create Function
     Function Name	Specify a function name.
     Description	(Optional) Specify a function description.
     Runtime	Select a runtime environment for the function.
     S3 Bucket	Specify the name of the S3 bucket where the deployment package is stored.
     S3 Key	Specify the deployment package's S3 object key. Maximum compressed size allowed is 50 MB. Maximum uncompressed size allowed is 250 MB.
     S3 Object Version	(Optional) Specify the deployment package's S3 object version.
     Handler	Specify the function within the code that Lambda calls to begin execution.
     Role ARN	Specify the Amazon Resource Name (ARN) of the IAM role that Lambda assumes when it executes the function to access any other Amazon Web Services (AWS) resources.
     Memory Size (MB)	Select the amount of memory, in MB, that Lambda allocates to the function. Info title Correlation between memory allocation and amount of CPU Lambda uses this memory size to infer the amount of CPU and memory allocated to the function. Your use-case determines your CPU and memory requirements. For example, a database operation might need less memory compared to an image processing function.
     Timeout (s)	Select the execution time, in seconds, at which Lambda should terminate the function.

     Role	see Create Function above
     Memory (MB)	see Create Function above
     Timeout (s)	see Create Function above
     Delete Function
     Don't fail for non existing function	Check to not fail the build, if the function does not exist (anymore). Clear to trigger a build failure otherwise.
     Function Name	see Create Function above
     Invoke Function
     Function Name	see Create Function above
     Payload	(Optional) Specify a JSON payload to provide to the Lambda function as input.
     Client Context	(Optional) Specify client-specific JSON information to pass to the Lambda function in the context variable.
     Invocation Type	Select the function invocation type. Info By default, the Invoke API assumes "RequestResponse" invocation type. You can optionally request asynchronous execution by specifying "Event" as the InvocationType. You can also use this parameter to request AWS Lambda to not execute the function but do some verification, such as if the caller is authorized to invoke the function and if the inputs are valid
     Log Type	(Optional) Select "Tail" to return the last 4 KB of log data produced by your Lambda function.
     Don't fail on handled function errors	Check to not fail the build, if an error has been handled by the function. Clear to trigger a build failure otherwise.
     Add Permission
     Function Name	see Create Function above
     Statement ID	Specify a unique statement identifier.
     Lambda Action	Specify the Lambda action to allow in this statement.
     Principal	Specify the principal who is granted this permission.
     Source Account	(Optional) Specify the AWS account ID (without a hyphen) of the source owner.
     Source ARN	(Optional) Specify the S3 bucket's Amazon Resource Name (ARN) to ensure that only events generated from the specified bucket can invoke the function. Note title Important If you add a permission for the Amazon S3 principal without providing the source ARN, any AWS account that creates a mapping to your function ARN can send events to invoke your Lambda function from Amazon S3.
