Ec2ServiceProps Struct ​

The properties for defining a service using the EC2 launch type.

Example ​

ts
declare const vpc: ec2.Vpc;

// Create an ECS cluster
const cluster = new ecs.Cluster(this, 'Cluster', { vpc });

// Add capacity to it
cluster.addCapacity('DefaultAutoScalingGroupCapacity', {
  instanceType: new ec2.InstanceType("t2.xlarge"),
});

const taskDefinition = new ecs.Ec2TaskDefinition(this, 'TaskDef');

taskDefinition.addContainer('DefaultContainer', {
  image: ecs.ContainerImage.fromRegistry("amazon/amazon-ecs-sample"),
  memoryLimitMiB: 512,
});

// Instantiate an Amazon ECS Service
const ecsService = new ecs.Ec2Service(this, 'Service', {
  cluster,
  taskDefinition,
  minHealthyPercent: 100,
  circuitBreaker: {
    enable: true,
  },
});

Properties ​

assignPublicIpbooleanassign_public_ipboolassignPublicIpBooleanAssignPublicIpboolAssignPublicIp*bool= false#
Specifies whether the task's elastic network interface receives a public IP address.

If true, each task will receive a public IP address.

This property is only used for tasks that use the awsvpc network mode.

Whether to use Availability Zone rebalancing for the service.
notes · default

If enabled: maxHealthyPercent must be greater than 100; daemon must be false; if there are any placementStrategies, the first must be "spread across Availability Zones"; there must be no placementConstraints using attribute:ecs.availability-zone, and the service must not be a target of a Classic Load Balancer.

Default: AvailabilityZoneRebalancing.ENABLED

capacityProviderStrategiesCapacityProviderStrategy[]capacity_provider_strategiestyping.List[CapacityProviderStrategy]capacityProviderStrategiesList<CapacityProviderStrategy>CapacityProviderStrategiesCapacityProviderStrategy[]CapacityProviderStrategies*[]CapacityProviderStrategy= undefined#
A list of Capacity Provider strategies used to place a service.
circuitBreakerDeploymentCircuitBreakercircuit_breakerDeploymentCircuitBreakercircuitBreakerDeploymentCircuitBreakerCircuitBreakerDeploymentCircuitBreakerCircuitBreakerDeploymentCircuitBreaker= disabled#
Whether to enable the deployment circuit breaker.

If this property is defined, circuit breaker will be implicitly enabled.

cloudMapOptionsCloudMapOptionscloud_map_optionsCloudMapOptionscloudMapOptionsCloudMapOptionsCloudMapOptionsCloudMapOptionsCloudMapOptionsCloudMapOptions= AWS Cloud Map service discovery …#
The options for configuring an Amazon ECS service to use service discovery.
default

Default: AWS Cloud Map service discovery is not enabled.

clusterIClusterclusterIClusterclusterIClusterClusterIClusterClusterIClusterrequired#
The name of the cluster that hosts the service.
daemonbooleandaemonbooldaemonBooleanDaemonboolDaemon*bool= false#
Specifies whether the service will use the daemon scheduling strategy.

If true, the service scheduler deploys exactly one task on each container instance in your cluster.

When you are using this strategy, do not specify a desired number of tasks or any task placement strategies.

deploymentAlarmsDeploymentAlarmConfigdeployment_alarmsDeploymentAlarmConfigdeploymentAlarmsDeploymentAlarmConfigDeploymentAlarmsDeploymentAlarmConfigDeploymentAlarmsDeploymentAlarmConfig= No alarms will be monitored duri…#
The alarm(s) to monitor during deployment, and behavior to apply if at least one enters a state of alarm during the deployment or bake time.
default

Default: No alarms will be monitored during deployment.

deploymentControllerDeploymentControllerdeployment_controllerDeploymentControllerdeploymentControllerDeploymentControllerDeploymentControllerDeploymentControllerDeploymentControllerDeploymentController= Rolling update (ECS)#
Specifies which deployment controller to use for the service.

For more information, see Amazon ECS Deployment Types

deploymentStrategyDeploymentStrategydeployment_strategyDeploymentStrategydeploymentStrategyDeploymentStrategyDeploymentStrategyDeploymentStrategyDeploymentStrategyDeploymentStrategy= ROLLING#
The deployment strategy to use for the service.
desiredCountnumberdesired_countint | floatdesiredCountNumberDesiredCountdoubleDesiredCount*float64= When creating the service, defau…#
The desired number of instantiations of the task definition to keep running on the service.
default

Default: When creating the service, default is 1; when updating the service, default uses the current task number.

enableECSManagedTagsbooleanenable_ecs_managed_tagsboolenableECSManagedTagsBooleanEnableECSManagedTagsboolEnableECSManagedTags*bool= false#
Specifies whether to enable Amazon ECS managed tags for the tasks within the service.

For more information, see Tagging Your Amazon ECS Resources

enableExecuteCommandbooleanenable_execute_commandboolenableExecuteCommandBooleanEnableExecuteCommandboolEnableExecuteCommand*bool= undefined#
Whether to enable the ability to execute into a container.
forceNewDeploymentForceNewDeploymentforce_new_deploymentForceNewDeploymentforceNewDeploymentForceNewDeploymentForceNewDeploymentForceNewDeploymentForceNewDeploymentForceNewDeployment= no forced deployment#
Configuration for forcing a new deployment of the service.
notes

By default, deployments aren't forced. You can use this option to start a new deployment with no service definition changes. For example, you can update a service's tasks to use a newer Docker image with the same image/tag combination (my_image:latest) or to roll Fargate tasks onto a newer platform version.

This is equivalent to calling the forceNewDeployment() method, but allows you to configure it declaratively at construction time, including the ability to explicitly disable it with enabled: false.

healthCheckGracePeriodDurationhealth_check_grace_periodDurationhealthCheckGracePeriodDurationHealthCheckGracePeriodDurationHealthCheckGracePeriodDuration= defaults to 60 seconds if at lea…#
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.
