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? For information about function aliases, see CreateAlias and AliasRoutingConfiguration in the API docs.

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) Lambda Function name or ARN.function_version
- (Required) Lambda function version for which you are creating the alias. Pattern: (\$LATEST|[0-9]+)
.routing_config
- (Optional) The Lambda alias' route configuration settings. Fields documented belowrouting_config
supports the following arguments:
additional_version_weights
- (Optional) A map that defines the proportion of events that should be sent to different versions of a lambda function.This resource exports the following attributes in addition to the arguments above:
arn
- The Amazon Resource Name (ARN) identifying your Lambda function alias.invoke_arn
- The ARN to be used for invoking Lambda Function from API Gateway - to be used in aws_api_gateway_integration
's uri
In Terraform v1.5.0 and later, use an import
block to import Lambda Function Aliases using the function_name/alias
. For example:
import {
to = aws_lambda_alias.test_lambda_alias
id = "my_test_lambda_function/my_alias"
}
Using terraform import
, import Lambda Function Aliases using the function_name/alias
. For example:
% terraform import aws_lambda_alias.test_lambda_alias my_test_lambda_function/my_alias
