[ aws . lambda ]



Returns the specified alias information such as the alias ARN, description, and function version it is pointing to. For more information, see Introduction to AWS Lambda Aliases .

This requires permission for the lambda:GetAlias action.

See 'aws help' for descriptions of global parameters.


--function-name <value>
--name <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--function-name (string)

Function name for which the alias is created. An alias is a subresource that exists only in the context of an existing Lambda function so you must specify the function name. 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 of the alias for which you want to retrieve information.

--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.


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. 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.
