Hi. Is anyone able to point me in the direction of an example/documentation whereby autoscaling is attached to a fargate service? I've been unable to find anything

<https://www.pulumi.com/docs/guides/crosswalk/aws/ecs/#creating-an-auto-scaling-group-for-ecs-cluster-instances>

That's scaling the underlying cluster, not the service(s) on top. I need App auto scaling. I've found various pieces but not managed to get it all working yet. Trying to work backwards from cloudformation templates but only had moderate success

Hi <@UMRF75FAA> were you able to figure it out?

yeah i put something together after a fair amount of struggling

```
const cluster = new awsx.ecs.Cluster('cluster', { vpc }, { provider });
const nginx = new awsx.ecs.FargateService(
  'nginx',
  {...},
  { provider }
);

const ecsTarget = new aws.appautoscaling.Target(
  'ecs-target',
  {
    maxCapacity: 4,
    minCapacity: 1,
    resourceId: pulumi.interpolate`service/${cluster.cluster.name}/${nginx.service.name}`,
    scalableDimension: 'ecs:service:DesiredCount',
    serviceNamespace: 'ecs',
  },
  { provider }
);

const ecsPolicy = new aws.appautoscaling.Policy(
  'ecsPolicy',
  {
    policyType: 'TargetTrackingScaling',
    resourceId: ecsTarget.resourceId,
    scalableDimension: ecsTarget.scalableDimension,
    serviceNamespace: ecsTarget.serviceNamespace,
    targetTrackingScalingPolicyConfiguration: {
      predefinedMetricSpecification: {
        predefinedMetricType: 'ECSServiceAverageCPUUtilization',
      },
      targetValue: 70,
    },
  },
  { provider }
);
```

<@UMRF75FAA> can you also list the import for pulumi.interpolate

`import * as pulumi from '@pulumi/pulumi';`

Yes Thanks <@UMRF75FAA>, it's working well now.
