Then when I read the docs there is a `aws.ecs.Cluster.get('cluster_name', 'arn:...')` But then I get the `error reading ECS Cluster: InvalidParameterException: Unsupported resource type: cluster`

it's not the arn you need for this, it's the cluster name. You want something like:

`const cluster = aws.ecs.Cluster.get("name", "cluster_name");`

Ok, it does work. But when I do it, I get an `aws.ecs.Cluster` when I need a `awsx.ecs.Cluster`

I want to get the cluster to create another FargateService

you shouldn't need a specific object to create the service, you could just use the `ClusterArn` on either object

when I try
```new awsx.ecs.FargateService('name', {
  cluster: awsx.ecs.Cluster.getDefault({id: 'arn:...', urn: 'urn:...'}),
  ...
});```

Do you actually want _the_ default cluster or do you want the cluster specified by the ID?

But I have no idea how to get a `awsx.ecs.Cluster` by the id and `aws.ecs.Cluster` wont work

and the reason is because the type is  `FargateServiceArgs.cluster: awsx.ecs.Cluster`

shouldn't it be:
```var cluster = ...;
new awsx.ecs.FargateService('name', {
   cluster: cluster.Arn,
   ...
});```
or am I not understanding that fargate service parameter? I'm surprised that it needs the entire object that's silly. You can always make you fargate service using the core API and not `awsx` .

It does need the entire object. Reason being is that awsx is supposed to create clusters and services etc with best practices. If you want to do more complicated you're going to need to use the base provider

the solution is a little strange for me, but is the follow:

```const cluster = aws.ecs.Cluster.get(...)
new awsx.ecs.FargateService('name', {
   cluster: new aws.ecs.Cluster('clustar_name', {cluster: cluster}),
   ...
});```
