NetworkTargetGroupProps¶

class aws_cdk.aws_elasticloadbalancingv2.NetworkTargetGroupProps(*, deregistration_delay=None, health_check=None, target_group_name=None, target_type=None, vpc=None, port, preserve_client_ip=None, protocol=None, proxy_protocol_v2=None, targets=None)¶

Bases: aws_cdk.aws_elasticloadbalancingv2.BaseTargetGroupProps

Properties for a new Network Target Group.

Parameters

deregistration_delay (Optional[Duration]) – The amount of time for Elastic Load Balancing to wait before deregistering a target. The range is 0-3600 seconds. Default: 300
health_check (Union[HealthCheck, Dict[str, Any], None]) – Health check configuration. Default: - The default value for each property in this configuration varies depending on the target.
target_group_name (Optional[str]) – The name of the target group. This name must be unique per region per account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, and must not begin or end with a hyphen. Default: - Automatically generated.
target_type (Optional[TargetType]) – The type of targets registered to this TargetGroup, either IP or Instance. All targets registered into the group must be of this type. If you register targets to the TargetGroup in the CDK app, the TargetType is determined automatically. Default: - Determined automatically.
vpc (Optional[IVpc]) – The virtual private cloud (VPC). only if TargetType is Ip or InstanceId Default: - undefined
port (Union[int, float]) – The port on which the listener listens for requests.
preserve_client_ip (Optional[bool]) – Indicates whether client IP preservation is enabled. Default: false if the target group type is IP address and the target group protocol is TCP or TLS. Otherwise, true.
protocol (Optional[Protocol]) – Protocol for target group, expects TCP, TLS, UDP, or TCP_UDP. Default: - TCP
proxy_protocol_v2 (Optional[bool]) – Indicates whether Proxy Protocol version 2 is enabled. Default: false
targets (Optional[Sequence[INetworkLoadBalancerTarget]]) – The targets to add to this target group. Can be Instance, IPAddress, or any self-registering load balancing target. If you use either Instance or IPAddress as targets, all target must be of the same type. Default: - No targets.

Attributes

deregistration_delay¶

The amount of time for Elastic Load Balancing to wait before deregistering a target.

The range is 0-3600 seconds.

Default: 300
Return type: Optional[Duration]

health_check¶

Health check configuration.

Default

The default value for each property in this configuration varies depending on the target.

See

Return type

Optional[HealthCheck]

port¶

The port on which the listener listens for requests.

Return type: Union[int, float]

preserve_client_ip¶

Indicates whether client IP preservation is enabled.

Default

false if the target group type is IP address and the target group protocol is TCP or TLS. Otherwise, true.

Return type: Optional[bool]

protocol¶

Protocol for target group, expects TCP, TLS, UDP, or TCP_UDP.

Default

TCP

Return type
