class aws_cdk.aws_stepfunctions_tasks.EcsRunTaskProps(*, comment=None, heartbeat=None, input_path=None, integration_pattern=None, output_path=None, result_path=None, result_selector=None, timeout=None, cluster, launch_target, task_definition, assign_public_ip=None, container_overrides=None, security_groups=None, subnets=None)¶

Bases: aws_cdk.aws_stepfunctions.TaskStateBaseProps

Properties for ECS Tasks.

Parameters

comment (Optional[str]) – An optional description for this state. Default: - No comment
heartbeat (Optional[Duration]) – Timeout for the heartbeat. Default: - None
input_path (Optional[str]) – JSONPath expression to select part of the state to be the input to this state. May also be the special value JsonPath.DISCARD, which will cause the effective input to be the empty object {}. Default: - The entire task input (JSON path ‘$’)
integration_pattern (Optional[IntegrationPattern]) – AWS Step Functions integrates with services directly in the Amazon States Language. You can control these AWS services using service integration patterns Default: IntegrationPattern.REQUEST_RESPONSE
output_path (Optional[str]) – JSONPath expression to select select a portion of the state output to pass to the next state. May also be the special value JsonPath.DISCARD, which will cause the effective output to be the empty object {}. Default: - The entire JSON node determined by the state input, the task result, and resultPath is passed to the next state (JSON path ‘$’)
result_path (Optional[str]) – JSONPath expression to indicate where to inject the state’s output. May also be the special value JsonPath.DISCARD, which will cause the state’s input to become its output. Default: - Replaces the entire input with the result (JSON path ‘$’)
result_selector (Optional[Mapping[str, Any]]) – The JSON that will replace the state’s raw result and become the effective result before ResultPath is applied. You can use ResultSelector to create a payload with values that are static or selected from the state’s raw result. Default: - None
timeout (Optional[Duration]) – Timeout for the state machine. Default: - None
cluster (ICluster) – The ECS cluster to run the task on.
launch_target (IEcsLaunchTarget) – An Amazon ECS launch type determines the type of infrastructure on which your tasks and services are hosted.
task_definition (TaskDefinition) – [disable-awslint:ref-via-interface] Task Definition used for running tasks in the service. Note: this must be TaskDefinition, and not ITaskDefinition, as it requires properties that are not known for imported task definitions
assign_public_ip (Optional[bool]) – Assign public IP addresses to each task. Default: false
container_overrides (Optional[Sequence[ContainerOverride]]) – Container setting overrides. Specify the container to use and the overrides to apply. Default: - No overrides
security_groups (Optional[Sequence[ISecurityGroup]]) – Existing security groups to use for the tasks. Default: - A new security group is created
subnets (Optional[SubnetSelection]) – Subnets to place the task’s ENIs. Default: - Public subnets if assignPublicIp is set. Private subnets otherwise.

Example:

vpc = ec2.Vpc.from_lookup(self, "Vpc",
    is_default=True
)

cluster = ecs.Cluster(self, "Ec2Cluster", vpc=vpc)
cluster.add_capacity("DefaultAutoScalingGroup",
    instance_type=ec2.InstanceType("t2.micro"),
    vpc_subnets=ec2.SubnetSelection(subnet_type=ec2.SubnetType.PUBLIC)
)

task_definition = ecs.TaskDefinition(self, "TD",
    compatibility=ecs.Compatibility.EC2
)

task_definition.add_container("TheContainer",
    image=ecs.ContainerImage.from_registry("foo/bar"),
    memory_limit_mi_b=256
)

run_task = tasks.EcsRunTask(self, "Run",
    integration_pattern=sfn.IntegrationPattern.RUN_JOB,
    cluster=cluster,
    task_definition=task_definition,
    launch_target=tasks.EcsEc2LaunchTarget(
        placement_strategies=[
            ecs.PlacementStrategy.spread_across_instances(),
            ecs.PlacementStrategy.packed_by_cpu(),
            ecs.PlacementStrategy.randomly()
        ],
        placement_constraints=[
            ecs.PlacementConstraint.member_of("blieptuut")
        ]
    )
