AWS::Lambda::LayerVersionPermission - AWS CloudFormation

AWS::Lambda::LayerVersionPermission

The AWS::Lambda::LayerVersionPermission resource adds permissions to the resource-based policy of a version of an Lambda layer. Use this action to grant layer usage permission to other accounts. You can grant permission to a single account, all AWS accounts, or all accounts in an organization.

Important

Since the release of the UpdateReplacePolicy both UpdateReplacePolicy and DeletionPolicy are required to protect your Resources/LayerPermissions from deletion.
