How do I attach EBS volume to ECS scheduled task

[mikeyangyo]

Hi all,
I have found ECS.ServiceManagedVolume for ECS service to launch an EBS volume as service volume.
But it seems like EBS volume cannot attach to scheduled task because there is no volumeConfigurations parameter in AWS::Events::Rule EcsParameters

following is my code snippet.

import {
  aws_applicationautoscaling as appscaling,
  aws_ec2 as ec2,
  aws_ecs as ecs,
} from "aws-cdk-lib";
import { ScheduledFargateTask } from "aws-cdk-lib/aws-ecs-patterns";
import { Construct } from "constructs";

export class Compute extends Construct {
  constructor(scope: Construct, id: string) {
    super(scope, id);

    let vpc: ec2.IVpc;
    let serviceSubnets: ec2.SubnetSelection;
    const cluster = new ecs.Cluster(this, "cluster", { vpc });
    const volume = new ecs.ServiceManagedVolume(this, "volume", {
      name: "ebs",
      managedEBSVolume: {
        snapShotId: "snap-REDACTED",
        volumeType: ec2.EbsDeviceVolumeType.GP3,
        fileSystemType: ecs.FileSystemType.XFS,
        tagSpecifications: [
          {
            propagateTags: ecs.EbsPropagatedTagSource.TASK_DEFINITION,
          },
        ],
      },
    });
    const taskDefinition = new ecs.FargateTaskDefinition(
      this,
      "task-definition",
      {
        cpu: 256,
        memoryLimitMiB: 512,
      },
    );
    const container = taskDefinition.addContainer("cron-container", {
      image: ecs.ContainerImage.fromEcrRepository(imageRegistry, imageTag),
      logging: new ecs.AwsLogDriver({ streamPrefix: this.node.id }),
    });

    volume.mountIn(container, {
      readOnly: false,
      containerPath: "/secrets",
    });
    taskDefinition.addVolume({
      name: volume.name,
    });

    new ScheduledFargateTask(this, "cron", {
      cluster,
      scheduledFargateTaskDefinitionOptions: {
        taskDefinition,
      },
      // UTC+0
      schedule: appscaling.Schedule.cron({ minute: "0" }),
      desiredTaskCount: 1,
      vpc,
      subnetSelection: serviceSubnets,
      propagateTags: ecs.PropagatedTagSource.TASK_DEFINITION,
    });
  }
}

after task was invoked, and I attach into container. I cannot find any attached volume in it.
