ExampleMetadata:: infused

Example:

import aws_cdk.aws_elasticloadbalancingv2_targets as targets
import aws_cdk.aws_ecs as ecs
import aws_cdk.aws_ecs_patterns as patterns

# vpc: ec2.Vpc


task = ecs.FargateTaskDefinition(self, "Task", cpu=256, memory_limit_mi_b=512)
task.add_container("nginx",
    image=ecs.ContainerImage.from_registry("public.ecr.aws/nginx/nginx:latest"),
    port_mappings=[ecs.PortMapping(container_port=80)]
)

svc = patterns.ApplicationLoadBalancedFargateService(self, "Service",
    vpc=vpc,
    task_definition=task,
    public_load_balancer=False
)

nlb = elbv2.NetworkLoadBalancer(self, "Nlb",
    vpc=vpc,
    cross_zone_enabled=True,
    internet_facing=True
)

listener = nlb.add_listener("listener", port=80)

listener.add_targets("Targets",
    targets=[targets.AlbTarget(svc.load_balancer, 80)],
    port=80
)

CfnOutput(self, "NlbEndpoint", value=f"http://{nlb.loadBalancerDnsName}")

Parameters:

alb (ApplicationLoadBalancer) – The application load balancer to load balance to.
port (Union[int, float]) – The port on which the target is listening.

Methods

attach_to_network_target_group(target_group)
