Amazon VPC Lattice

{'protocol': {'TLS_PASSTHROUGH'}}

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.

type clientToken:

string

param clientToken:

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.

This field is autopopulated if not provided.

type defaultAction:

dict

param defaultAction:

[REQUIRED]

The action for the default rule. Each listener has a default rule. The default rule is used if no other rules match.

• fixedResponse (dict) --

  The fixed response action. The rule returns a custom HTTP response.

  • statusCode (integer) -- [REQUIRED]

    The HTTP response code.

• forward (dict) --

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

  • targetGroups (list) -- [REQUIRED]

    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 the traffic goes to that target group.

    • (dict) --

      Describes the weight of a target group.

      • targetGroupIdentifier (string) -- [REQUIRED]

        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.

type name:

string

param name:

[REQUIRED]

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.

type port:

integer

param port:

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

type protocol:

string

param protocol:

[REQUIRED]

The listener protocol.

type serviceIdentifier:

string

param serviceIdentifier:

[REQUIRED]

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

type tags:

dict

param tags:

The tags for the listener.

• (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:.

  • (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: _ . : / = + - @

Creates a target group. A target group is a collection of targets, or compute resources, that run your application or service. A target group can only be used by a single service.

The action for the default rule.

    The HTTP response code.

• forward (dict) --

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

  • targetGroups (list) -- [REQUIRED]

    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 the traffic goes to that target group.

    • (dict) --

      Describes the weight of a target group.

      • targetGroupIdentifier (string) -- [REQUIRED]

        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.
