Example

Use values for string values and values_yaml for non-string values.

data "carvel_ytt" "tpl1" {
  files = ["ytt-k8s"]

  values = {
    prop1 = "val1"
  }

  values_yaml = {
    prop2 = true
    prop3 = 156
  }
}

output "result" {
  value = "${data.carvel_ytt.tpl1.result}"
}

Use config_yaml to provide more complex data values

data "carvel_ytt" "tpl1" {
  files = ["ytt-k8s"]

  config_yaml = <<EOF
    #@data/values
    ---
    cm1: "cm1"
    cm2: "cm3"
  EOF

  values = {
    cm1 = "cm1-updated"
    "cm3.nested" = "cm3-updated"
  }
}

output "result" {
  value = "${data.carvel_ytt.tpl1.result}"
}
