public class LayerVersion
extends com.pulumi.resources.CustomResource

Manages an AWS Lambda Layer Version. Use this resource to share code and dependencies across multiple Lambda functions. For information about Lambda Layers and how to use them, see [AWS Lambda Layers](https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html). > **Note:** Setting `skipDestroy` to `true` means that the AWS Provider will not destroy any layer version, even when running `pulumi destroy`. Layer versions are thus intentional dangling resources that are not managed by Pulumi and may incur extra expense in your AWS account. ## Example Usage ### Basic Layer

AWS Lambda Layers expect source code to be provided as a deployment package whose structure varies depending on which `compatibleRuntimes` this layer specifies. See [Runtimes](https://docs.aws.amazon.com/lambda/latest/dg/API_PublishLayerVersion.html#SSS-PublishLayerVersion-request-CompatibleRuntimes) for the valid values of `compatibleRuntimes`. Once you have created your deployment package you can specify it either directly as a local file (using the `filename` argument) or indirectly via Amazon S3 (using the `s3Bucket`, `s3Key` and `s3ObjectVersion` arguments). When providing the deployment package via S3 it may be useful to use the `aws.s3.BucketObjectv2` resource to upload it. For larger deployment packages it is recommended by Amazon to upload via S3, since the S3 API has better support for uploading large files efficiently. ## Import ### Identity Schema #### Required * `layerName` (String) Unique name for the Lambda Layer. * `version` (String) Lambda Layer version number. #### Optional * `accountId` (String) AWS Account where this resource is managed. * `region` (String) Region where this resource is managed. Using `pulumi import`, import Lambda Layer Versions using the `arn`. For example: ```sh $ pulumi import aws:lambda/layerVersion:LayerVersion example arn:aws:lambda:us-west-2:123456789012:layer:example:1 ```
