Use CreateAlias with a CLI

To create an alias for a Lambda function

The following create-alias example creates an alias named LIVE that points to version 1 of the my-function Lambda function.

aws lambda create-alias \
    --function-name my-function \
    --description "alias for live version of function" \
    --function-version 1 \
    --name LIVE

Output:

{
    "FunctionVersion": "1",
    "Name": "LIVE",
    "AliasArn": "arn:aws:lambda:us-west-2:123456789012:function:my-function:LIVE",
    "RevisionId": "873282ed-4cd3-4dc8-a069-d0c647e470c6",
    "Description": "alias for live version of function"
}

Example 1: This example creates a New Lambda Alias for specified version and routing configuration to specify the percentage of invocation requests that it receives.

New-LMAlias -FunctionName "MylambdaFunction123" -RoutingConfig_AdditionalVersionWeight @{Name="1";Value="0.6} -Description "Alias for version 4" -FunctionVersion 4 -Name "PowershellAlias"
