Edit:

cluster.eksCluster.name.apply

seems to work a bit differently than I thought. so basically using it like this seems to work:

cluster.eksCluster.name.apply((eksClusterName) => {
  const nodegroup = new eks.NodeGroup(`${name}-nodegroup`, {
    cluster,
    instanceProfile,
    labels: {
      role: 'managed-nodes',
    },
    instanceType: 't2.medium',
    desiredCapacity: 1,
    minSize: 1,
    maxSize: 3,
    autoScalingGroupTags: {
      ['<http://k8s.io/cluster-autoscaler/enabled|k8s.io/cluster-autoscaler/enabled>']: 'true',
      [`<http://k8s.io/cluster-autoscaler/${eksClusterName}`|k8s.io/cluster-autoscaler/${eksClusterName}`>]: 'owned',
    },
  });

------------ Original: Hi! Im trying to setup an eks cluster with k8s cluster autoscaler. To get this to work, I need to tag the nodegroup with:

autoScalingGroupTags: {
    ['<http://k8s.io/cluster-autoscaler/enabled|k8s.io/cluster-autoscaler/enabled>']: 'true',
    [`<http://k8s.io/cluster-autoscaler/${cluster.eksCluster.name}`|k8s.io/cluster-autoscaler/${cluster.eksCluster.name}`>]: 'owned',
  },

However, the operation fails since

Template format error: YAML not well-formed

Checking details shows that

cluster.eksCluster.name

is never expanded to the name, instead it becomes:

<http://k8s.io/cluster-autoscaler/Calling|k8s.io/cluster-autoscaler/Calling> [toString] on an [Output<T>] is not supported....

Im creating the cluster with

const cluster = new eks.Cluster(name, { options });

But the eks cluster dont just get the name

name

, but

${name}-eksCluster-1234567

The number seems to be generated on creation, so I would really need some way of extracting it so I can use it in my tag. I have tried `pulumi.interpolate`k8s.io/cluster-autoscaler/${cluster.eksCluster.name}`` and

cluster.eksCluster.name.apply(v => `<http://k8s.io/cluster-autoscaler/${v}`|k8s.io/cluster-autoscaler/${v}`>)

but they both fail with

error TS2464: A computed property name must be of type 'string', 'number', 'symbol', or 'any'.

Any ideas?
