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

  • 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.

  • deployment_alarms (Union[DeploymentAlarmConfig, Dict[str, Any], None]) – 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: - No alarms will be monitored during deployment.

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

  • 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

  • enable_execute_command (Optional[bool]) – Whether to enable the ability to execute into a container. Default: - undefined

  • 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

  • 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. Valid values are: PropagatedTagSource.SERVICE, PropagatedTagSource.TASK_DEFINITION or PropagatedTagSource.NONE Default: PropagatedTagSource.NONE

  • service_connect_configuration (Union[ServiceConnectProps, Dict[str, Any], None]) – Configuration for Service Connect. Default: No ports are advertised via Service Connect on this service, and the service cannot make requests to other services via Service Connect.

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

  • task_definition (TaskDefinition) – The task definition to use for tasks in the service. [disable-awslint:ref-via-interface]

  • assign_public_ip (Optional[bool]) – 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. Default: false

  • daemon (Optional[bool]) – 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 orany task placement strategies. Default: false

  • placement_constraints (Optional[Sequence[PlacementConstraint]]) – The placement constraints to use for tasks in the service. For more information, see Amazon ECS Task Placement Constraints. Default: - No constraints.

  • placement_strategies (Optional[Sequence[PlacementStrategy]]) – The placement strategies to use for tasks in the service. For more information, see Amazon ECS Task Placement Strategies. Default: - No strategies.

  • security_groups (Optional[Sequence[ISecurityGroup]]) – The security groups to associate with the service. If you do not specify a security group, a new security group is created. This property is only used for tasks that use the awsvpc network mode. Default: - A new security group is created.

  • vpc_subnets (Union[SubnetSelection, Dict[str, Any], None]) – The subnets to associate with the service. This property is only used for tasks that use the awsvpc network mode. Default: - Public subnets if assignPublicIp is set, otherwise the first available one of Private, Isolated, Public, in that order.
