Seeking assistance with TypeScript promises

Just starting out with typescript and nodejs, but I've got to tackle some issues in the typescript code.

I'm looking to execute an ECS one-off task using Pulumi. I have the documentation on how to run the task from the taskDefinition, which can be found here.

However, without a detailed explanation, I'm struggling to understand how to invoke the `run` action mentioned here: 

public run: (params: RunTaskRequest) => Promise<awssdk.ECS.Types.RunTaskResponse>;

There's an example provided for running this with api-gateway, but it doesn't clarify how to call the `run` function as a stand-alone action. You can check it out here.

Any advice or assistance would be greatly appreciated!

UPD: Here is the more detailed block of code that I'm working with:

const kafkaTask = new awsx.ecs.FargateTaskDefinition("kafka1-task-efs", {
    vpc: vpcSelected,
    containers: {
        kafkaTask: {
            image: imageKafkaTaskEfs,
            logConfiguration: {
                logDriver: "awslogs",
                options: {
                    "awslogs-group": "ecs-kafka1",
                    "awslogs-region": "eu-central-1",
                    "awslogs-stream-prefix": "kafka1-task-efs"
                }
            },
            mountPoints: [
                {containerPath: "/mnt/kafka/data", sourceVolume: "kafka-data"},
                {containerPath: "/mnt/kafka/secrets", sourceVolume: "kafka-secrets"},
                {containerPath: "/mnt/zookeeper/log", sourceVolume: "zookeeper-log"},
                {containerPath: "/mnt/zookeeper/data", sourceVolume: "zookeeper-data"}
            ]
        }
    },
    volumes: [
        {name: "kafka-data", efsVolumeConfiguration: {rootDirectory: "/kafka-data", fileSystemId: fsKafka.id}},
        {
            name: "kafka-secrets",
            efsVolumeConfiguration: {rootDirectory: "/kafka-secrets", fileSystemId: fsKafka.id}
        },
        {
            name: "zookeeper-log",
            efsVolumeConfiguration: {rootDirectory: "/zookeeper-log", fileSystemId: fsKafka.id}
        },
        {
            name: "zookeeper-data",
            efsVolumeConfiguration: {rootDirectory: "/zookeeper-data", fileSystemId: fsKafka.id}
        }
    ]
});

kafkaTask.run({ cluster }).then(res => console.log(res));

UPD2: I encountered the following error, not sure if it provides any helpful insights:

error: Running program '/pulumi/main-infrastructure' failed with an unhandled exception:
Error: Cannot call '.get' during update or preview.
To manipulate the value of this Output, use '.apply' instead.

Answer №1

If you're struggling with where the issue lies, it seems like you need to instantiate an object of type EC2TaskDefinition. Here's a basic framework to get you started:

const taskDef = new EC2TaskDefinition('', {}, {})

taskDef.execute({})
.then(response => console.log(response))

It looks like there are some parameters that need to be filled in, and if creating an instance is the problem, please let me know so I can provide more guidance on that aspect.
