Creates a Lambda function alias.
---
# aws\_lambda\_alias
Creates a Lambda function alias. Creates an alias that points to the specified Lambda function version.
For information about Lambda and how to use it, see [What is AWS Lambda?][1]
For information about function aliases, see [CreateAlias][2] in the API docs.
## Example Usage
```
resource "aws_lambda_alias" "test_alias" {
name = "testalias"
description = "a sample description"
function_name = "${aws_lambda_function.lambda_function_test.arn}"
function_version = "$LATEST"
}
```
## Argument Reference
* `name` - (Required) Name for the alias you are creating. Pattern: `(?!^[0-9]+$)([a-zA-Z0-9-_]+)`
* `description` - (Optional) Description of the alias.
* `function_name` - (Required) The function ARN of the Lambda function for which you want to create an alias.
* `function_version` - (Required) Lambda function version for which you are creating the alias. Pattern: `(\$LATEST|[0-9]+)`.
