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)

The name of the alias.

--function-version (string)

The function version that the alias invokes.

--description (string)

A description of the alias.

--routing-config (structure)

The routing configuration of the alias.

Shorthand Syntax:

AdditionalVersionWeights={KeyName1=double,KeyName2=double}

JSON Syntax:

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

--revision-id (string)

Only update the alias if the revision ID matches the ID that's specified. Use this option to avoid modifying an alias that has changed since you last read it.

--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.
