Synopsis

  create-alias
--function-name <value>
--name <value>
--function-version <value>
[--description <value>]
[--routing-config <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--function-name (string)

Name of the Lambda function for which you want to create an alias. Note that the length constraint applies only to the ARN. If you specify only the function name, it is limited to 64 characters in length.

--name (string)

Name for the alias you are creating.

--function-version (string)

Lambda function version for which you are creating the alias.

--description (string)

description of the alias.

--routing-config (structure)

Specifies an additional version your alias can point to, allowing you to dictate what percentage of traffic will invoke each version. For more information, see lambda-traffic-shifting-using-aliases .

Shorthand Syntax:

AdditionalVersionWeights={KeyName1=double,KeyName2=double}

JSON Syntax:

{
  "AdditionalVersionWeights": {"string": double
    ...}
}

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Output

AliasArn -> (string)

Lambda function ARN that is qualified using the alias name as the suffix. For example, if you create an alias called BETA that points to a helloworld function version, the ARN is arn:aws:lambda:aws-regions:acct-id:function:helloworld:BETA .

Name -> (string)

name name.

FunctionVersion -> (string)

Function version to which the alias points.

Description -> (string)

name description.

RoutingConfig -> (structure)

Specifies an additional function versions the alias points to, allowing you to dictate what percentage of traffic will invoke each version. For more information, see lambda-traffic-shifting-using-aliases .

AdditionalVersionWeights -> (map)

Set this value to dictate what percentage of traffic will invoke the updated function version. If set to an empty string, 100 percent of traffic will invoke function-version . For more information, see lambda-traffic-shifting-using-aliases .

key -> (string)

value -> (double)

RevisionId -> (string)

Represents the latest updated revision of the function or alias.
