Bases: AddRuleProps

Properties for adding new targets to a listener.

Parameters:

  • conditions (Optional[Sequence[ListenerCondition]]) – Rule applies if matches the conditions. Default: - No conditions.

  • priority (Union[int, float, None]) – Priority of this target group. The rule with the lowest priority will be used for every request. If priority is not given, these target groups will be added as defaults, and must not have conditions. Priorities must be unique. Default: Target groups are used as defaults

  • 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: Duration.minutes(5)

  • enable_anomaly_mitigation (Optional[bool]) – Indicates whether anomaly mitigation is enabled. Only available when loadBalancingAlgorithmType is TargetGroupLoadBalancingAlgorithmType.WEIGHTED_RANDOM Default: false

  • 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.

  • load_balancing_algorithm_type (Optional[TargetGroupLoadBalancingAlgorithmType]) – The load balancing algorithm to select targets for routing requests. Default: round_robin.

  • port (Union[int, float, None]) – The port on which the listener listens for requests. Default: Determined from protocol if known

  • protocol (Optional[ApplicationProtocol]) – The protocol to use. Default: Determined from port if known

  • protocol_version (Optional[ApplicationProtocolVersion]) – The protocol version to use. Default: ApplicationProtocolVersion.HTTP1

  • slow_start (Optional[Duration]) – The time period during which the load balancer sends a newly registered target a linearly increasing share of the traffic to the target group. The range is 30-900 seconds (15 minutes). Default: 0

  • stickiness_cookie_duration (Optional[Duration]) – The stickiness cookie expiration period. Setting this value enables load balancer stickiness. After this period, the cookie is considered stale. The minimum value is 1 second and the maximum value is 7 days (604800 seconds). Default: Stickiness disabled

  • stickiness_cookie_name (Optional[str]) – The name of an application-based stickiness cookie. Names that start with the following prefixes are not allowed: AWSALB, AWSALBAPP, and AWSALBTG; they’re reserved for use by the load balancer. Note: stickinessCookieName parameter depends on the presence of stickinessCookieDuration parameter. If stickinessCookieDuration is not set, stickinessCookieName will be omitted. Default: - If stickinessCookieDuration is set, a load-balancer generated cookie is used. Otherwise, no stickiness is defined.

  • 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

  • targets (Optional[Sequence[IApplicationLoadBalancerTarget]]) – The targets to add to this target group. Can be Instance, IPAddress, or any self-registering load balancing target. All target must be of the same type.

infused

Example:

from aws_cdk.aws_autoscaling import AutoScalingGroup
# asg: AutoScalingGroup
# vpc: ec2.Vpc


# Create the load balancer in a VPC. 'internetFacing' is 'false'
# by default, which creates an internal load balancer.
lb = elbv2.ApplicationLoadBalancer(self, "LB",
    vpc=vpc,
    internet_facing=True
)

# Add a listener and open up the load balancer's security group
# to the world.
listener = lb.add_listener("Listener",
    port=80,

    # 'open: true' is the default, you can leave it out if you want. Set it
    # to 'false' and use `listener.connections` if you want to be selective
    # about who can access the load balancer.
    open=True
)

# Create an AutoScaling group and add it as a load balancing
# target to the listener.
listener.add_targets("ApplicationFleet",
    port=8080,
    targets=[asg]
)

Attributes

conditions

Rule applies if matches the conditions.

Default:

  • No conditions.

See:

https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-listeners.html

deregistration_delay

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

The range is 0-3600 seconds.

Default:

Duration.minutes(5)

enable_anomaly_mitigation

Indicates whether anomaly mitigation is enabled.

Only available when loadBalancingAlgorithmType is TargetGroupLoadBalancingAlgorithmType.WEIGHTED_RANDOM

Default:

false

See:

https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-target-groups.html#automatic-target-weights

health_check

Health check configuration.

Default:

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

See:

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-elasticloadbalancingv2-targetgroup.html#aws-resource-elasticloadbalancingv2-targetgroup-properties

load_balancing_algorithm_type

The load balancing algorithm to select targets for routing requests.

Default:

round_robin.

port

The port on which the listener listens for requests.

Default:

Determined from protocol if known

priority

Priority of this target group.

The rule with the lowest priority will be used for every request. If priority is not given, these target groups will be added as defaults, and must not have conditions.

Priorities must be unique.

Default:

Target groups are used as defaults

protocol

The protocol to use.

Default:

Determined from port if known

protocol_version

The protocol version to use.

Default:

ApplicationProtocolVersion.HTTP1

slow_start

The time period during which the load balancer sends a newly registered target a linearly increasing share of the traffic to the target group.

The range is 30-900 seconds (15 minutes).

Default:

0

The stickiness cookie expiration period.

Setting this value enables load balancer stickiness.

After this period, the cookie is considered stale. The minimum value is 1 second and the maximum value is 7 days (604800 seconds).

Default:

Stickiness disabled

The name of an application-based stickiness cookie.

Names that start with the following prefixes are not allowed: AWSALB, AWSALBAPP, and AWSALBTG; they’re reserved for use by the load balancer.

Note: stickinessCookieName parameter depends on the presence of stickinessCookieDuration parameter. If stickinessCookieDuration is not set, stickinessCookieName will be omitted.

Default:

  • If stickinessCookieDuration is set, a load-balancer generated cookie is used. Otherwise, no stickiness is defined.

See:

https://docs.aws.amazon.com/elasticloadbalancing/latest/application/sticky-sessions.html

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

targets

The targets to add to this target group.

Can be Instance, IPAddress, or any self-registering load balancing target. All target must be of the same type.
