public class Alias
extends com.pulumi.resources.CustomResource

Manages an AWS Lambda Alias. Use this resource to create an alias that points to a specific Lambda function version for traffic management and deployment strategies. For information about Lambda and how to use it, see [What is AWS Lambda?](http://docs.aws.amazon.com/lambda/latest/dg/welcome.html). For information about function aliases, see [CreateAlias](http://docs.aws.amazon.com/lambda/latest/dg/API_CreateAlias.html) and [AliasRoutingConfiguration](https://docs.aws.amazon.com/lambda/latest/dg/API_AliasRoutingConfiguration.html) in the API docs. ## Example Usage ### Basic Alias

## Import ### Identity Schema #### Required * `functionName` (String) Name or ARN of the Lambda function. * `name` (String) Name of the alias. #### Optional * `accountId` (String) AWS Account where this resource is managed. * `region` (String) Region where this resource is managed. Using `pulumi import`, import Lambda Function Aliases using `function_name/alias`. For example: ```sh $ pulumi import aws:lambda/alias:Alias example example-function/production ```
