create-rule¶

Description¶

Creates a listener rule. Each listener has a default rule for checking connection requests, but you can define additional rules. Each rule consists of a priority, one or more actions, and one or more conditions. For more information, see Listener rules in the Amazon VPC Lattice User Guide .

Options¶

--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
      }
      ...
    ]
  }
}

--client-token (string)

A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. If you retry a request that completed successfully using the same client token and parameters, the retry succeeds without performing any actions. If the parameters aren't identical, the retry fails.

--listener-identifier (string)

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

--match (tagged union structure)

The rule match.

Note
This is a Tagged Union structure. Only one of the following top level keys can be set: httpMatch.

httpMatch -> (structure)

The HTTP criteria that a rule must match.

headerMatches -> (list)

The header matches. Matches incoming requests with rule based on request header value before applying rule action.

(structure)

Describes the constraints for a header match. Matches incoming requests with rule based on request header value before applying rule action.

caseSensitive -> (boolean)

Indicates whether the match is case sensitive. Defaults to false.

match -> (tagged union structure)

The header match type.

Note
This is a Tagged Union structure. Only one of the following top level keys can be set: contains, exact, prefix.

contains -> (string)

Specifies a contains type match.

exact -> (string)

Specifies an exact type match.

prefix -> (string)

Specifies a prefix type match. Matches the value with the prefix.

name -> (string)

The name of the header.

method -> (string)

The HTTP method type.

pathMatch -> (structure)

The path match.

caseSensitive -> (boolean)

Indicates whether the match is case sensitive. Defaults to false.

match -> (tagged union structure)

The type of path match.

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

exact -> (string)

An exact match of the path.

prefix -> (string)

A prefix match of the path.

JSON Syntax:

{
  "httpMatch": {
    "headerMatches": [
      {
        "caseSensitive": true|false,
        "match": {
          "contains": "string",
          "exact": "string",
          "prefix": "string"
        },
        "name": "string"
      }
      ...
    ],
    "method": "string",
    "pathMatch": {
      "caseSensitive": true|false,
      "match": {
        "exact": "string",
        "prefix": "string"
      }
    }
  }
}

--name (string)

The name of the rule. The name must be unique within the listener. The valid characters are a-z, 0-9, and hyphens (-). You can't use a hyphen as the first or last character, or immediately after another hyphen.

--priority (integer)

The priority assigned to the rule. Each rule for a specific listener must have a unique priority. The lower the priority number the higher the priority.

--service-identifier (string)

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

--tags (map)

The tags for the rule.

key -> (string)

The key of the tag.

Constraints: Tag keys are case-sensitive and accept a maximum of 128 Unicode characters. Valid characters are Unicode letters, digits, white space, and any of the following symbols: _ . : / = + - @ May not begin with aws: .

value -> (string)

The value of the tag.

Constraints: Tag values are case-sensitive and accept a maximum of 256 Unicode characters. Valid characters are Unicode letters, digits, white space, and any of the following symbols: _ . : / = + - @

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

{"string": "string"
  ...}

--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.

text
table

--query (string)

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.
