Parameters

load_balancer (LoadBalancer) –

Return type

None

attach_to_network_target_group(target_group)

This method is called to attach this service to a Network Load Balancer.

Don’t call this function directly. Instead, call listener.addTargets() to add this service to a load balancer.

enable_cloud_map(*, cloud_map_namespace=None, dns_record_type=None, dns_ttl=None, failure_threshold=None, name=None)

Enable CloudMap service discovery for the service.

Parameters

  • cloud_map_namespace (Optional[INamespace]) – The service discovery namespace for the Cloud Map service to attach to the ECS service. Default: - the defaultCloudMapNamespace associated to the cluster

  • dns_record_type (Optional[DnsRecordType]) – The DNS record type that you want AWS Cloud Map to create. The supported record types are A or SRV. Default: DnsRecordType.A

  • dns_ttl (Optional[Duration]) – The amount of time that you want DNS resolvers to cache the settings for this record. Default: 60

  • failure_threshold (Union[int, float, None]) – The number of 30-second intervals that you want Cloud Map to wait after receiving an UpdateInstanceCustomHealthStatus request before it changes the health status of a service instance. NOTE: This is used for HealthCheckCustomConfig

return :rtype: Service :return: The created CloudMap service

load_balancer_target(*, container_name, container_port=None, protocol=None)

Return a load balancing target for a specific container and port.

Use this function to create a load balancer target if you want to load balance to another container than the first essential container or the first mapped port on the container.

Use the return value of this function where you would normally use a load balancer target, instead of the Service object itself.

Parameters
  • options

  • container_name (str) – The name of the container.

  • container_port (Union[int, float, None]) – The port number of the container. Only applicable when using application/network load balancers. Default: - Container port of the first added port mapping.

  • protocol (Optional[Protocol]) – The protocol used for the port mapping. Only applicable when using application load balancers. Default: Protocol.TCP

Example::

# Example automatically generated. See https://github.com/aws/jsii/issues/826 listener.add_targets(service.load_balancer_target(

container_name=”MyContainer”, container_port=1234

))

Return type

IEcsLoadBalancerTarget
