问如何将cdk映像资产部署到ecs集群

EN

    const vpc = new ec2.VpcNetwork(this, "MyVPC", { maxAZs: 3 });

    const cluster: ecs.Cluster = new ecs.Cluster(this, "ecs-cluster", {
      clusterName: "demo",
      vpc: vpc
    });

    cluster.addCapacity("MyEC2Capacity", {
      instanceType: new ec2.InstanceType("t2.micro"),
      desiredCapacity: 1
    });
    const image = new ecs.AssetImage(this, "image", {directory: "client"})

    const nameService = new ecs.LoadBalancedEc2Service (this, 'name-service', {
      cluster: cluster,
      desiredCount: 1,
      image: image,
      memoryLimitMiB: 128,
      containerPort: 3000
   });

Stack cdkTest
The cdkTest stack uses assets, which are currently not accounted for in the diff output! See https://github.com/awslabs/aws-cdk/issues/395
