The properties for the NetworkLoadBalancedEc2Service service.

Parameters
  • cloud_map_options (Optional[CloudMapOptions]) – The options for configuring an Amazon ECS service to use service discovery. Default: - AWS Cloud Map service discovery is not enabled.

  • cluster (Optional[ICluster]) – The name of the cluster that hosts the service. If a cluster is specified, the vpc construct should be omitted. Alternatively, you can omit both cluster and vpc. Default: - create a new cluster; if both cluster and vpc are omitted, a new VPC will be created for you.

  • desired_count (Union[int, float, None]) – The desired number of instantiations of the task definition to keep running on the service. The minimum value is 1. Default: 1

  • domain_name (Optional[str]) – The domain name for the service, e.g. “api.example.com.”. Default: - No domain name.

  • domain_zone (Optional[IHostedZone]) – The Route53 hosted zone for the domain, e.g. “example.com.”. Default: - No Route53 hosted domain zone.

  • enable_ecs_managed_tags (Optional[bool]) – Specifies whether to enable Amazon ECS managed tags for the tasks within the service. For more information, see Tagging Your Amazon ECS Resources Default: false

  • health_check_grace_period (Optional[Duration]) – The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started. Default: - defaults to 60 seconds if at least one load balancer is in-use and it is not already set

  • listener_port (Union[int, float, None]) – Listener port of the network load balancer that will serve traffic to the service. Default: 80

  • load_balancer (Optional[NetworkLoadBalancer]) – The network load balancer that will serve traffic to the service. [disable-awslint:ref-via-interface] Default: - a new load balancer will be created.

  • propagate_tags (Optional[PropagatedTagSource]) – Specifies whether to propagate the tags from the task definition or the service to the tasks in the service. Tags can only be propagated to the tasks within the service during service creation. Default: - none

  • public_load_balancer (Optional[bool]) – Determines whether the Load Balancer will be internet-facing. Default: true

  • service_name (Optional[str]) – The name of the service. Default: - CloudFormation-generated name.

  • task_image_options (Optional[NetworkLoadBalancedTaskImageOptions]) – The properties required to create a new task definition. One of taskImageOptions or taskDefinition must be specified. Default: - none

  • vpc (Optional[IVpc]) – The VPC where the container instances will be launched or the elastic network interfaces (ENIs) will be deployed. If a vpc is specified, the cluster construct should be omitted. Alternatively, you can omit both vpc and cluster. Default: - uses the VPC defined in the cluster or creates a new VPC.

  • cpu (Union[int, float, None]) – The number of cpu units used by the task. Valid values, which determines your range of valid values for the memory parameter: 256 (.25 vCPU) - Available memory values: 0.5GB, 1GB, 2GB 512 (.5 vCPU) - Available memory values: 1GB, 2GB, 3GB, 4GB 1024 (1 vCPU) - Available memory values: 2GB, 3GB, 4GB, 5GB, 6GB, 7GB, 8GB 2048 (2 vCPU) - Available memory values: Between 4GB and 16GB in 1GB increments 4096 (4 vCPU) - Available memory values: Between 8GB and 30GB in 1GB increments This default is set in the underlying FargateTaskDefinition construct. Default: none

  • memory_limit_mib (Union[int, float, None]) – The hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the allocated memory, the container is terminated. At least one of memoryLimitMiB and memoryReservationMiB is required. Default: - No memory limit.

  • memory_reservation_mib (Union[int, float, None]) – The soft limit (in MiB) of memory to reserve for the container. When system memory is under contention, Docker attempts to keep the container memory within the limit. If the container requires more memory, it can consume up to the value specified by the Memory property or all of the available memory on the container instance—whichever comes first. At least one of memoryLimitMiB and memoryReservationMiB is required. Default: - No memory reserved.

  • task_definition (Optional[Ec2TaskDefinition]) – The task definition to use for tasks in the service. TaskDefinition or TaskImageOptions must be specified, but not both.. [disable-awslint:ref-via-interface] Default: - none
