public class ResourcePolicy
extends com.pulumi.resources.CustomResource

Manages the complete IAM resource-based policy document for an AWS Lambda function, function version, or alias. > **Note:** `PutResourcePolicy` (used by this resource) replaces the *entire* resource-based policy on the Lambda resource, including any statements added with `aws.lambda.Permission`. Do not use `aws.lambda.ResourcePolicy` and `aws.lambda.Permission` on the same Lambda function, version, or alias — every apply of one will overwrite statements managed by the other. ## Example Usage ### Basic Usage

## Import ### Identity Schema #### Required - `resourceArn` (String) ARN of the Lambda function, function version, or function alias. Using `pulumi import`, import Lambda policies using the `resourceArn`. For example: ```sh $ pulumi import aws:lambda/resourcePolicy:ResourcePolicy example arn:aws:lambda:us-east-1:123456789012:function:example ```
