type ListenerArn

string

param ListenerArn

[REQUIRED]

The Amazon Resource Name (ARN) of the listener.

type EndpointGroupRegion

string

param EndpointGroupRegion

[REQUIRED]

The AWS Region where the endpoint group is located. A listener can have only one endpoint group in a specific Region.

type EndpointConfigurations

list

param EndpointConfigurations

The list of endpoint objects.

  • (dict) --

    A complex type for endpoints. A resource must be valid and active when you add it as an endpoint.

    • EndpointId (string) --

      An ID for the endpoint. If the endpoint is a Network Load Balancer or Application Load Balancer, this is the Amazon Resource Name (ARN) of the resource. If the endpoint is an Elastic IP address, this is the Elastic IP address allocation ID. For Amazon EC2 instances, this is the EC2 instance ID. A resource must be valid and active when you add it as an endpoint.

      An Application Load Balancer can be either internal or internet-facing.

    • Weight (integer) --

      The weight associated with the endpoint. When you add weights to endpoints, you configure AWS Global Accelerator to route traffic based on proportions that you specify. For example, you might specify endpoint weights of 4, 5, 5, and 6 (sum=20). The result is that 4/20 of your traffic, on average, is routed to the first endpoint, 5/20 is routed both to the second and third endpoints, and 6/20 is routed to the last endpoint. For more information, see Endpoint Weights in the AWS Global Accelerator Developer Guide .

    • ClientIPPreservationEnabled (boolean) --

      Indicates whether client IP address preservation is enabled for an Application Load Balancer endpoint. The value is true or false. The default value is true for new accelerators.

      If the value is set to true, the client's IP address is preserved in the X-Forwarded-For request header as traffic travels to applications on the Application Load Balancer endpoint fronted by the accelerator.

      For more information, see Preserve Client IP Addresses in AWS Global Accelerator in the AWS Global Accelerator Developer Guide .

type TrafficDialPercentage

float

param TrafficDialPercentage

The percentage of traffic to send to an AWS Region. Additional traffic is distributed to other endpoint groups for this listener.

Use this action to increase (dial up) or decrease (dial down) traffic to a specific Region. The percentage is applied to the traffic that would otherwise have been routed to the Region based on optimal routing.

The default value is 100.

type HealthCheckPort

integer

param HealthCheckPort

The port that AWS Global Accelerator uses to check the health of endpoints that are part of this endpoint group. The default port is the listener port that this endpoint group is associated with. If listener port is a list of ports, Global Accelerator uses the first port in the list.

type HealthCheckProtocol

string

param HealthCheckProtocol

The protocol that AWS Global Accelerator uses to check the health of endpoints that are part of this endpoint group. The default value is TCP.

type HealthCheckPath

string

param HealthCheckPath

If the protocol is HTTP/S, then this specifies the path that is the destination for health check targets. The default value is slash (/).

type HealthCheckIntervalSeconds

integer

param HealthCheckIntervalSeconds

The time—10 seconds or 30 seconds—between each health check for an endpoint. The default value is 30.

type ThresholdCount

integer

param ThresholdCount

The number of consecutive health checks required to set the state of a healthy endpoint to unhealthy, or to set an unhealthy endpoint to healthy. The default value is 3.

type IdempotencyToken

string

param IdempotencyToken

[REQUIRED]

A unique, case-sensitive identifier that you provide to ensure the idempotency—that is, the uniqueness—of the request.

This field is autopopulated if not provided.

type PortOverrides

list

param PortOverrides

Override specific listener ports used to route traffic to endpoints that are part of this endpoint group. For example, you can create a port override in which the listener receives user traffic on ports 80 and 443, but your accelerator routes that traffic to ports 1080 and 1443, respectively, on the endpoints.

For more information, see Port overrides in the AWS Global Accelerator Developer Guide .

  • (dict) --

    Override specific listener ports used to route traffic to endpoints that are part of an endpoint group. For example, you can create a port override in which the listener receives user traffic on ports 80 and 443, but your accelerator routes that traffic to ports 1080 and 1443, respectively, on the endpoints.

    For more information, see Port overrides in the AWS Global Accelerator Developer Guide .

    • ListenerPort (integer) --

      The listener port that you want to map to a specific endpoint port. This is the port that user traffic arrives to the Global Accelerator on.

    • EndpointPort (integer) --

      The endpoint port that you want a listener port to be mapped to. This is the port on the endpoint, such as the Application Load Balancer or Amazon EC2 instance.

          The percentage of traffic to send to an AWS Region. Additional traffic is distributed to other endpoint groups for this listener.

          Use this action to increase (dial up) or decrease (dial down) traffic to a specific Region. The percentage is applied to the traffic that would otherwise have been routed to the Region based on optimal routing.

          The default value is 100.

        • HealthCheckPort (integer) --

          The port that Global Accelerator uses to perform health checks on endpoints that are part of this endpoint group.

          The default port is the port for the listener that this endpoint group is associated with. If the listener port is a list, Global Accelerator uses the first specified port in the list of ports.

        • HealthCheckProtocol (string) --

          The protocol that Global Accelerator uses to perform health checks on endpoints that are part of this endpoint group. The default value is TCP.

        • HealthCheckPath (string) --

          If the protocol is HTTP/S, then this value provides the ping path that Global Accelerator uses for the destination on the endpoints for health checks. The default is slash (/).

        • HealthCheckIntervalSeconds (integer) --

          The time—10 seconds or 30 seconds—between health checks for each endpoint. The default value is 30.

        • ThresholdCount (integer) --

          The number of consecutive health checks required to set the state of a healthy endpoint to unhealthy, or to set an unhealthy endpoint to healthy. The default value is 3.

        • PortOverrides (list) --

          Allows you to override the destination ports used to route traffic to an endpoint. Using a port override lets you to map a list of external destination ports (that your users send traffic to) to a list of internal destination ports that you want an application endpoint to receive traffic on.

          • (dict) --

            Override specific listener ports used to route traffic to endpoints that are part of an endpoint group. For example, you can create a port override in which the listener receives user traffic on ports 80 and 443, but your accelerator routes that traffic to ports 1080 and 1443, respectively, on the endpoints.

            For more information, see Port overrides in the AWS Global Accelerator Developer Guide .

            • ListenerPort (integer) --

              The listener port that you want to map to a specific endpoint port. This is the port that user traffic arrives to the Global Accelerator on.

            • EndpointPort (integer) --

              The endpoint port that you want a listener port to be mapped to. This is the port on the endpoint, such as the Application Load Balancer or Amazon EC2 instance.

    • NextToken (string) --

      The token for the next set of results. You receive this token from a previous call.

type EndpointGroupArn

string

param EndpointGroupArn

[REQUIRED]

The Amazon Resource Name (ARN) of the endpoint group.

type EndpointConfigurations

list

param EndpointConfigurations

The list of endpoint objects. A resource must be valid and active when you add it as an endpoint.

  • (dict) --

    A complex type for endpoints. A resource must be valid and active when you add it as an endpoint.

    • EndpointId (string) --

      An ID for the endpoint. If the endpoint is a Network Load Balancer or Application Load Balancer, this is the Amazon Resource Name (ARN) of the resource. If the endpoint is an Elastic IP address, this is the Elastic IP address allocation ID. For Amazon EC2 instances, this is the EC2 instance ID. A resource must be valid and active when you add it as an endpoint.

      An Application Load Balancer can be either internal or internet-facing.

    • Weight (integer) --

      The weight associated with the endpoint. When you add weights to endpoints, you configure AWS Global Accelerator to route traffic based on proportions that you specify. For example, you might specify endpoint weights of 4, 5, 5, and 6 (sum=20). The result is that 4/20 of your traffic, on average, is routed to the first endpoint, 5/20 is routed both to the second and third endpoints, and 6/20 is routed to the last endpoint. For more information, see Endpoint Weights in the AWS Global Accelerator Developer Guide .

    • ClientIPPreservationEnabled (boolean) --

      Indicates whether client IP address preservation is enabled for an Application Load Balancer endpoint. The value is true or false. The default value is true for new accelerators.

      If the value is set to true, the client's IP address is preserved in the X-Forwarded-For request header as traffic travels to applications on the Application Load Balancer endpoint fronted by the accelerator.

      For more information, see Preserve Client IP Addresses in AWS Global Accelerator in the AWS Global Accelerator Developer Guide .
