Options

--default-action (tagged union structure)

The action for the default rule.

Note

This is a Tagged Union structure. Only one of the following top level keys can be set: fixedResponse, forward.

fixedResponse -> (structure)

Describes the rule action that returns a custom HTTP response.

statusCode -> (integer)

The HTTP response code.

forward -> (structure)

The forward action. Traffic that matches the rule is forwarded to the specified target groups.

targetGroups -> (list)

The target groups. Traffic matching the rule is forwarded to the specified target groups. With forward actions, you can assign a weight that controls the prioritization and selection of each target group. This means that requests are distributed to individual target groups based on their weights. For example, if two target groups have the same weight, each target group receives half of the traffic.

The default value is 1. This means that if only one target group is provided, there is no need to set the weight; 100% of traffic will go to that target group.

(structure)

Describes the weight of a target group.

targetGroupIdentifier -> (string)

The ID or Amazon Resource Name (ARN) of the target group.

weight -> (integer)

Only required if you specify multiple target groups for a forward action. The "weight" determines how requests are distributed to the target group. For example, if you specify two target groups, each with a weight of 10, each target group receives half the requests. If you specify two target groups, one with a weight of 10 and the other with a weight of 20, the target group with a weight of 20 receives twice as many requests as the other target group. If there's only one target group specified, then the default value is 100.

JSON Syntax:

{
  "fixedResponse": {
    "statusCode": integer
  },
  "forward": {
    "targetGroups": [
      {
        "targetGroupIdentifier": "string",
        "weight": integer
      }
      ...
    ]
  }
}

--listener-identifier (string)

The ID or Amazon Resource Name (ARN) of the listener.

--service-identifier (string)

The ID or Amazon Resource Name (ARN) of the service.

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

• json
• text
• table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

• on
• off
• auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Output

arn -> (string)

The Amazon Resource Name (ARN) of the listener.

defaultAction -> (tagged union structure)
