# google\_compute\_instance

Get information about a VM instance resource within GCE. For more information see
[the official documentation](https://cloud.google.com/compute/docs/instances)
and
[API](https://cloud.google.com/compute/docs/reference/latest/instances).


## Example Usage

```hcl
data "google_compute_instance" "appserver" {
	name = "primary-application-server"
	zone = "us-central1-a"
}
```

## Argument Reference

The following arguments are supported:

* `self_link` - (Optional) The self link of the instance. One of `name` or `self_link` must be provided.

* `name` - (Optional) The name of the instance. One of `name` or `self_link` must be provided.

---

* `project` - (Optional) The ID of the project in which the resource belongs.
    If `self_link` is provided, this value is ignored.  If neither `self_link`
    nor `project` are provided, the provider project is used.

* `zone` - (Optional) The zone of the instance. If `self_link` is provided, this
    value is ignored.  If neither `self_link` nor `zone` are provided, the
    provider zone is used.
