create-listener¶

Description¶

Creates a listener for a service. Before you start using your Amazon VPC Lattice service, you must add one or more listeners. A listener is a process that checks for connection requests to your services. For more information, see Listeners in the Amazon VPC Lattice User Guide .

Options¶

--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.

--default-action (tagged union structure)

The action for the default rule. Each listener has a default rule. Each rule consists of a priority, one or more actions, and one or more conditions. The default rule is the rule that’s used if no other rules match. Each rule must include exactly one of the following types of actions: forward or fixed-response , and it must be the last action to be performed.

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
      }
      ...
    ]
  }
}

--name (string)

The name of the listener. A listener name must be unique within a service. 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.

--port (integer)

The listener port. You can specify a value from 1 to 65535 . For HTTP, the default is 80 . For HTTPS, the default is 443 .

--protocol (string)

The listener protocol HTTP or HTTPS.

Possible values:

HTTP

HTTPS

--service-identifier (string)

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

--tags (map)

The tags for the listener.

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 | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

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
yaml
yaml-stream

--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.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

base64
raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To create a listener

The following create-listener example creates an HTTPS listener with a default rule that forwards traffic to the specified VPC Lattice target group.

aws vpc-lattice create-listener \
    --name my-service-listener \
    --protocol HTTPS \
    --port 443 \
    --service-identifier svc-0285b53b2eEXAMPLE \
    --default-action file://listener-config.json

Contents of listener-config.json:

{
    "forward": {
        "targetGroups": [
            {
                "targetGroupIdentifier": "tg-0eaa4b9ab4EXAMPLE"
            }
        ]
    }
}

Output:

{
    "arn": "arn:aws:vpc-lattice:us-east-2:123456789012:service/svc-0285b53b2eEXAMPLE/listener/listener-07cc7fb0abEXAMPLE",

                    "weight": 100
                }
            ]
        }
    },
    "id": "listener-07cc7fb0abEXAMPLE",
    "name": "my-service-listener",
    "port": 443,
    "protocol": "HTTPS",
