Properties

NameTypeDescription
envResourceEnvironmentThe environment this resource belongs to.
layerVersionArnstringThe ARN of the Lambda Layer version that this Layer defines.
nodeNodeThe tree node.
stackStackThe stack in which this resource is defined.
compatibleRuntimes?Runtime[]The runtimes compatible with this Layer.

env

Type: ResourceEnvironment

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.


layerVersionArn

Type: string

The ARN of the Lambda Layer version that this Layer defines.


node

Type: Node

The tree node.


stack

Type: Stack

The stack in which this resource is defined.


compatibleRuntimes?

Type: Runtime[] (optional, default: Runtime.All)

The runtimes compatible with this Layer.

Methods

NameDescription
addPermission(id, permission)Add permission for this layer version to specific entities.
applyRemovalPolicy(policy)Apply the given removal policy to this resource.

addPermission(id, permission)

public addPermission(id: string, permission: LayerVersionPermission): void

Parameters

  • id string — the ID of the grant in the construct tree.
  • permission LayerVersionPermission — the identification of the grantee.

Add permission for this layer version to specific entities.

Usage within the same account where the layer is defined is always allowed and does not require calling this method. Note that the principal that creates the Lambda function using the layer (for example, a CloudFormation changeset execution role) also needs to have the lambda:GetLayerVersion permission on the layer version.


applyRemovalPolicy(policy)

public applyRemovalPolicy(policy: RemovalPolicy): void

Parameters

  • policy RemovalPolicy

Apply the given removal policy to this resource.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).
