sample

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
app = cdk.App()

env = {
    "account": process.env.CDK_DEFAULT_ACCOUNT,
    "region": process.env.CDK_DEFAULT_REGION
}

stack = cdk.Stack(app, "run-task-demo-stack", env=env)

# define your task
task = ecs.FargateTaskDefinition(stack, "Task", cpu=256, memory_limit_mi_b=512)

# add contianer into the task
task.add_container("Ping",
    image=ecs.ContainerImage.from_registry("busybox"),
    command=["sh", "-c", "ping -c 3 google.com"
    ],
    logging=ecs.AwsLogDriver(
        stream_prefix="Ping",
        log_group=LogGroup(stack, "LogGroup",
            log_group_name=f"{stack.stackName}LogGroup",
            retention=RetentionDays.ONE_DAY
        )
    )
)

# deploy and run this task once
run_task_at_once = RunTask(stack, "RunDemoTaskOnce", task=task)

# or run it with schedule(every hour 0min)
RunTask(stack, "RunDemoTaskEveryHour",
    task=task,
    cluster=run_task_at_once.cluster,
    run_once=False,
    schedule=Schedule.cron(minute="0")
)

ECS Anywhere

Amazon ECS Anywhere allows you to run ECS tasks on external instances. To run external task once or on schedule:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
external_task = ecs.TaskDefinition(stack, "ExternalTask",
    cpu="256",
    memory_mi_b="512",
    compatibility=ecs.Compatibility.EXTERNAL
)

external_task.add_container("ExternalPing",
    image=ecs.ContainerImage.from_registry("busybox"),
    command=["sh", "-c", "ping -c 3 google.com"
    ],
    logging=ecs.AwsLogDriver(
        stream_prefix="Ping",
        log_group=LogGroup(stack, "ExternalLogGroup",
            retention=RetentionDays.ONE_DAY,
            removal_policy=cdk.RemovalPolicy.DESTROY
        )
    )
)

# run it once on external instance
RunTask(stack, "RunDemoTaskFromExternal",
    task=external_task,
    cluster=existing_cluster,
    launch_type=LaunchType.EXTERNAL
)

# run it by schedule  on external instance
RunTask(stack, "RunDemoTaskFromExternalSchedule",
    task=external_task,
    cluster=existing_cluster,
    launch_type=LaunchType.EXTERNAL,
    run_at_once=False,
    schedule=Schedule.cron(minute="0")
)

Please note when you run task in EXTERNAL launch type, no fargate tasks will be scheduled. You will be responsible to register the external instances to your ECS cluster. See Registering an external instance to a cluster for more details.
