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
platform_version (Optional[FargatePlatformVersion]) – The platform version on which to run your service. If one is not specified, the LATEST platform version is used by default. For more information, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide. Default: Latest
task_definition (Optional[FargateTaskDefinition]) – 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
task_subnets (Union[SubnetSelection, Dict[str, Any], None]) – The subnets to associate with the service. Default: - Public subnets if assignPublicIp is set, otherwise the first available one of Private, Isolated, Public, in that order.
circuit_breaker (Union[DeploymentCircuitBreaker, Dict[str, Any], None]) – Whether to enable the deployment circuit breaker. If this property is defined, circuit breaker will be implicitly enabled. Default: - disabled
cloud_map_options (Union[CloudMapOptions, Dict[str, Any], None]) – 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.
deployment_controller (Union[DeploymentController, Dict[str, Any], None]) – Specifies which deployment controller to use for the service. For more information, see Amazon ECS Deployment Types Default: - Rolling update (ECS)
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: - If the feature flag, ECS_REMOVE_DEFAULT_DESIRED_COUNT is false, the default is 1; if true, the default is 1 for all new services and uses the existing services desired count when updating an existing service.
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[INetworkLoadBalancer]) – The network load balancer that will serve traffic to the service. If the load balancer has been imported, the vpc attribute must be specified in the call to fromNetworkLoadBalancerAttributes(). [disable-awslint:ref-via-interface] Default: - a new load balancer will be created.
max_healthy_percent (Union[int, float, None]) – The maximum number of tasks, specified as a percentage of the Amazon ECS service’s DesiredCount value, that can run in a service during a deployment. Default: - 100 if daemon, otherwise 200
min_healthy_percent (Union[int, float, None]) – The minimum number of tasks, specified as a percentage of the Amazon ECS service’s DesiredCount value, that must continue to run and remain healthy during a deployment. Default: - 0 if daemon, otherwise 50
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
record_type (Optional[NetworkLoadBalancedServiceRecordType]) – Specifies whether the Route53 record should be a CNAME, an A record using the Alias feature or no record at all. This is useful if you need to work with DNS systems that do not support alias records. Default: NetworkLoadBalancedServiceRecordType.ALIAS
service_name (Optional[str]) – The name of the service. Default: - CloudFormation-generated name.
task_image_options (Union[NetworkLoadBalancedTaskImageOptions, Dict[str, Any], None]) – 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.
