Description

I am trying to use Template Provider (https://www.terraform.io/docs/providers/template/index.html) on GCP but getting the error below:

Error: google_compute_instance_template.poc: : invalid or unknown key: user_data

Does Terraform support template_file Data source on Google Cloud Platform?

New or Affected Resource(s)

google_compute_instance_template

• google_XXXXX

Potential Terraform Configuration

data "google_compute_image" "coreos" {
    family  = "coreos-stable"
    project = "coreos-cloud"
}

data "template_file" "ct" {
  count = "${var.count}"
  depends_on  = ["data.template_file.etcd_discovery_url"]
  template = "${file("xxx.tpl")}"
  vars {
    hostname = "${var.xxx}"
    shortname = "${var.xxx}"
    docker_repo = "${var.xxx}"
    gcp_region = "${var.xxx}"
    etcd_discovery_url = "${file("${var.etcd_discovery_token_file_path}")}",
  }
}

data "ct_config" "service" {
  pretty_print = true
  platform = "gcs"
  content      = "${data.template_file.ct.rendered}"
}

data "template_file" "etcd_discovery_url" {
    template = "${file("/dev/null")}"
}

resource "google_compute_instance_template" "xx" {
  count = "${var.xxx}"
  name           = "${var.xxx}template"
  machine_type   = "${var.xxx}"
  can_ip_forward = false
  **user_data = "${element(data.ct_config.service.*.rendered, count.index)}"**

  tags = ["xx", "xxx"]

  disk {
    source_image = "xxx"
  }

  network_interface {
    #network = "default"
    subnetwork = "xxxx"
    access_config = {
    #The presence of this property assigns a public IP address to each Compute Instance. 
    #We intentionally leave it blank so that external IP is selected automatically.
      nat_ip = ""
    }
  }
}

I am getting the error below during the terraform run:

Error: google_compute_instance_template.poc: : invalid or unknown key: user_data

I changed user_data with metadata and got past the error for now.

metadata = "${element(data.ct_config.service.*.rendered, count.index)}"

In hashicorp/terraform#20514, that I had opened few weeks ago, following was mentioned:

"The user_data attribute is provider-specific, and not available for google_compute_instance: https://www.terraform.io/docs/providers/google/r/compute_instance.html"
