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 or any 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.
