Description

Creates an alias that points to the specified Lambda function version. For more information, see Introduction to AWS Lambda Aliases .

Alias names are unique for a given function. This requires permission for the lambda:CreateAlias action.

See 'aws help' for descriptions of global parameters.

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)

The name of the lambda function.

Name formats

• Function name - MyFunction .
• Function ARN - arn:aws:lambda:us-west-2:123456789012:function:MyFunction .
• Partial ARN - 123456789012:function:MyFunction .

The length constraint applies only to the full 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 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. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--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)

Alias name.

FunctionVersion -> (string)

Function version to which the alias points.

Description -> (string)

Alias description.

RoutingConfig -> (structure)

Specifies an additional function versions the alias points to, allowing you to dictate what percentage of traffic will invoke each version.

AdditionalVersionWeights -> (map)

The name of the second alias, and the percentage of traffic that is routed to it.

key -> (string)

value -> (double)

RevisionId -> (string)

Represents the latest updated revision of the function or alias.
