# google\_compute\_disk

Creates a new persistent disk within GCE, based on another disk.

~> **Note:** All arguments including the disk encryption key will be stored in the raw state as plain-text.
[Read more about sensitive data in state](/docs/state/sensitive-data.html).

## Example Usage

```hcl
resource "google_compute_disk" "default" {
  name  = "test-disk"
  type  = "pd-ssd"
  zone  = "us-central1-a"
  image = "debian-cloud/debian-8"
}
```

## Argument Reference

The following arguments are supported:

* `name` - (Required) A unique name for the resource, required by GCE.
    Changing this forces a new resource to be created.

* `zone` - (Required) The zone where this disk will be available.

- - -

* `disk_encryption_key_raw` - (Optional) A 256-bit [customer-supplied encryption key]
    (https://cloud.google.com/compute/docs/disks/customer-supplied-encryption),
    encoded in [RFC 4648 base64](https://tools.ietf.org/html/rfc4648#section-4)
    to encrypt this disk.

* `image` - (Optional) The image from which to initialize this disk. This can be
    one of: the image's `self_link`, `projects/{project}/global/images/{image}`,
    `projects/{project}/global/images/family/{family}`, `global/images/{image}`,
    `global/images/family/{family}`, `family/{family}`, `{project}/{family}`,
    `{project}/{image}`, `{family}`, or `{image}`.

* `project` - (Optional) The project in which the resource belongs. If it
    is not provided, the provider project is used.

* `size` - (Optional) The size of the image in gigabytes. If not specified, it
    will inherit the size of its base image.

* `snapshot` - (Optional) Name of snapshot from which to initialize this disk.

* `type` - (Optional) The GCE disk type.

## Attributes Reference

In addition to the arguments listed above, the following computed attributes are
exported:

* `disk_encryption_key_sha256` - The [RFC 4648 base64]
    (https://tools.ietf.org/html/rfc4648#section-4) encoded SHA-256 hash of the
    [customer-supplied encryption key](https://cloud.google.com/compute/docs/disks/customer-supplied-encryption)
    that protects this resource.

* `self_link` - The URI of the created resource.
