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"
}
