Layer
Provides a Lambda Layer Version resource. Lambda Layers allow you to reuse shared bits of code across multiple lambda functions. For information about Lambda Layers and how to use them, see AWS Lambda Layers.
NOTE: Setting
skip_destroytotruemeans that the AWS Provider will not destroy any layer version, even when running destroy. Layer versions are thus intentional dangling resources that are not managed by the provider and may incur extra expense in your AWS account.
Example Usage
package generated_program;
import com.pulumi.Context;
import com.pulumi.Pulumi;
import com.pulumi.core.Output;
import com.pulumi.aws.lambda.LayerVersion;
import com.pulumi.aws.lambda.LayerVersionArgs;
import com.pulumi.asset.FileArchive;
import java.util.List;
import java.util.ArrayList;
import java.util.Map;
import java.io.File;
import java.nio.file.Files;
import java.nio.file.Paths;
public class App {
public static void main(String[] args) {
Pulumi.run(App::stack);
}
public static void stack(Context ctx) {
var lambdaLayer = new LayerVersion("lambdaLayer", LayerVersionArgs.builder()
.compatibleRuntimes("nodejs16.x")
.code(new FileArchive("lambda_layer_payload.zip"))
.layerName("lambda_layer_name")
.build());
}
}Specifying the Deployment Package
AWS Lambda Layers expect source code to be provided as a deployment package whose structure varies depending on which compatible_runtimes this layer specifies. See Runtimes for the valid values of compatible_runtimes. 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 s3_bucket, s3_key and s3_object_version 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
Lambda Layers can be imported using arn.
$ pulumi import aws:lambda/layerVersion:LayerVersion \aws_lambda_layer_version.test_layer
arn:aws:lambda:REGION:ACCOUNT_ID:layer:LAYER_NAME:LAYER_VERSION
Properties
List of Architectures this layer is compatible with. Currently x86_64 and arm64 can be specified.
List of Runtimes this layer is compatible with. Up to 5 runtimes can be specified.
Date this resource was created.
Description of what your Lambda Layer does.
License info for your Lambda Layer. See License Info.
Object version containing the function's deployment package. Conflicts with filename.
ARN of a signing job.
ARN for a signing profile version.
Whether to retain the old version of a previously deployed Lambda Layer. Default is false. When this is not set to true, changing any of compatible_architectures, compatible_runtimes, description, filename, layer_name, license_info, s3_bucket, s3_key, s3_object_version, or source_code_hash forces deletion of the existing layer version and creation of a new layer version.
Used to trigger updates. Must be set to a base64-encoded SHA256 hash of the package file specified with either filename or s3_key.
Size in bytes of the function .zip file.
