Terraform Configuration Files

data "kubernetes_service" "this" {
  metadata {
    labels = {
      "release" = helm_release.this.name
    }
    namespace = var.namespace
  }
}

n.a.

Panic Output

n.a.

Steps to Reproduce

1. terraform plan

Expected Behavior

terraform plan should not error.

Actual Behavior

As stated in #854, terraform plan complains about the name field to be mandatory

Error: resource name may not be empty

Important Factoids

I would expect the data source to behave like kubectl get service therefor it should be possible to retrieve resources just by their labels. E.g. kubectl get service -l mylabel=myvalue
