awslambda.CompatibleRuntimes

Query Syntax

<hook.data_key>

Dedicated lookup for use with AwsLambdaHook based hooks.

To use this hook, there must be a AwsLambdaHook based hook defined in the pre_deploy section of the CFNgin configuration file. This hook must also define a data_key that is unique within the CFNgin configuration file (it can be reused in other CFNgin configuration files). The data_key is then passed to the lookup as it’s input/query. This allows the lookup to function during a runway plan.

A list of strings or None is returned by this lookup. The returned value can be passed directly to AWS::Lambda::LayerVersion.CompatibleRuntimes.

New in version 2.5.0.

Arguments

This lookup only supports the transform argument which can be used to turn the list of strings into a comma delimited list.
