Create Alias

lambda_create_alias R Documentation

Creates an alias for a Lambda function version

Description

Creates an alias for a Lambda function version. Use aliases to provide clients with a function identifier that you can update to invoke a different version.

You can also map an alias to split invocation requests between two versions. Use the RoutingConfig parameter to specify a second version and the percentage of invocation requests that it receives.

Usage

lambda_create_alias(FunctionName, Name, FunctionVersion, Description,
  RoutingConfig)

FunctionName

[required] The name or ARN of the Lambda function.
