talos_cluster_health times out when adding new nodes

[rmvangun]

When creating a basic Talos cluster with Terraform, I think there's a kind of logical problem that fails health checks in the plan phase when adding new nodes. The talos_cluster_health data source takes a list of all controlplane and workers. The first run, this is fine, the nodes are configured, and the health check passes. However, the second time, let's say you increase your worker node count. Now, the health check times out in the plan phase. The reason is that it now expects an additional worker node to be available. However, that node hasn't yet been given machine configuration in the apply step.

So, the health check runs during the plan phase, expects a new healthy worker node that has yet to be configured, and so fails the check.

Here's the cluster health config:

data "talos_cluster_health" "this" {
  depends_on = [talos_cluster_kubeconfig.this]

  client_configuration   = talos_machine_secrets.this.client_configuration
  control_plane_nodes    = module.controlplanes.*.node
  worker_nodes           = module.workers.*.node
  endpoints              = module.controlplanes.*.endpoint
}

Add a new node, and the plan times out with: data.talos_cluster_health.this: Still reading... [20s elapsed]

Not sure how to fix this, wish the health check just knew not to check on nodes that have yet to be configured in the planning phase.
