awslambda.CodeSha256

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 string is returned by this lookup. The returned value can be passed directly to AWS::Lambda::Version.CodeSha256.

New in version 2.5.0.
