Constructs a new instance of the ApplicationMultipleTargetGroupsFargateService class.

Parameters
  • scope (Construct) –

  • id (str) –

  • assign_public_ip (Optional[bool]) – Determines whether the service will be assigned a public IP address. Default: false

  • 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: 256

  • memory_limit_mib (Union[int, float, None]) – The amount (in MiB) of memory used by the task. This field is required and you must use one of the following values, which determines your range of valid values for the cpu parameter: 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) - Available cpu values: 256 (.25 vCPU) 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) - Available cpu values: 512 (.5 vCPU) 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) - Available cpu values: 1024 (1 vCPU) Between 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) - Available cpu values: 2048 (2 vCPU) Between 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) - Available cpu values: 4096 (4 vCPU) This default is set in the underlying FargateTaskDefinition construct. Default: 512

  • task_definition (Optional[FargateTaskDefinition]) – The task definition to use for tasks in the service. Only one of TaskDefinition or TaskImageOptions must be specified. [disable-awslint:ref-via-interface] Default: - none

  • 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. Default: 1

  • 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

  • load_balancers (Optional[List[ApplicationLoadBalancerProps]]) – The application load balancer that will serve traffic to the service. Default: - a new load balancer with a listener 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

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

  • target_groups (Optional[List[ApplicationTargetProps]]) – Properties to specify ALB target groups. Default: - default portMapping registered as target group and attached to the first defined listener

  • task_image_options (Optional[ApplicationLoadBalancedTaskImageProps]) – The properties required to create a new task definition. Only one of TaskDefinition or TaskImageOptions 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.
