GCE terraform refresh google_compute_instance does not refresh machine_type

[leighmhart]

Terraform Version 0.8.2 but issue is also present in 0.8.5

Affected Resource(s)

Please list the resources as a list, for example:

• google_compute_instance

Terraform Configuration Files

resource "google_compute_instance" "testInstance" {
  name = "testInstance"
  description = "testInstance"
  machine_type = "custom-1-6144"
  zone = "europe-west1-b"

  lifecycle {
    ignore_changes = [
      "create_timeout"
    ]
  }

  disk {
    disk = "disk-1"
    device_name = "disk1"
    auto_delete = "false"
  }

  network_interface {
    subnetwork = "somewhere-europe-west"
  }

  can_ip_forward = "false"
}

Debug Output

Please contact me privately for Gist link, but it is easily repeatable, see below.

Panic Output:

none

Expected Behavior

https://www.terraform.io/docs/commands/refresh.html

reconcile the state Terraform knows about (via its state file) with the real-world infrastructure. This can be used to detect any drift from the last-known state, and to update the state file.

Actual Behavior

The state file is not updated from the real-world infrastructure.

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. deploy a google_compute_instance with terraform
2. edit the machine-type using GCP's console's sizing recommendations tool (https://cloud.google.com/compute/docs/instances/viewing-sizing-recommendations-for-instances)
3. terraform refresh - does not update state from GCP

Important Factoids

https://cloud.google.com/compute/docs/instances/viewing-sizing-recommendations-for-instances

is a new feature (currently listed as Beta, but widely adopted) - so there may have been an assumption in the Terraform code for google_compute_instance to not need to refresh normally un-editable resource attributes via the console.

Hi @mbfrahry,
