# google\_compute\_image
|
||||
|
||||
Get information about a Google Compute Image. Check that your service account has the `compute.imageUser` role if you want to share [custom images](https://cloud.google.com/compute/docs/images/sharing-images-across-projects) from another project. If you want to use [public images](https://cloud.google.com/compute/docs/images#os-compute-support), do not forget to specify the dedicated project. For more information see
|
||||
[the official documentation](https://cloud.google.com/compute/docs/images) and its [API](https://cloud.google.com/compute/docs/reference/latest/images).
|
||||
|
||||
## Example Usage
|
||||
|
||||
```hcl
|
||||
data "google_compute_image" "my_image" {
|
||||
name = "image"
|
||||
# could also use family = "family-name"
|
||||
}
|
||||
|
||||
resource "google_compute_instance" "default" {
|
||||
name = "test"
|
||||
machine_type = "n1-standard-1"
|
||||
zone = "us-central1-a"
|
||||
|
||||
boot_disk {
|
||||
initialize_params {
|
||||
image = "${data.google_compute_image.my_image.self_link}"
|
||||
}
|
||||
}
|
||||
|
||||
network_interface {
|
||||
network = "default"
|
||||
|
||||
access_config {
|
||||
// Ephemeral IP
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Argument Reference
|
||||
|
||||
The following arguments are supported:
|
||||
|
||||
* `name` or `family` - (Required) The name of a specific image or a family.
|
||||
Exactly one of `name` of `family` must be specified. If `name` is specified, it will fetch
|
||||
the corresponding image. If `family` is specified, it will returns the latest image
|
||||
that is part of an image family and is not deprecated.
|
||||
|
||||
- - -
|
||||
|
||||
* `project` - (Optional) The project in which the resource belongs. If it
|
||||
is not provided, the provider project is used.
|
||||
|
||||
## Attributes Reference
|
||||
|
||||
In addition to the arguments listed above, the following computed attributes are
|
||||
exported:
|
||||
|
||||
* `self_link` - The URI of the image.
|
||||
* `name` - The name of the image.
|
||||
* `family` - The family name of the image.
|
||||
* `disk_size_gb` - The size of the image when restored onto a persistent disk in gigabytes.
|
||||
* `archive_size_bytes` - The size of the image tar.gz archive stored in Google Cloud Storage in bytes.
|
||||
* `image_id` - The unique identifier for the image.
|
||||
* `image_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 image.
|
||||
* `source_image_id` - The ID value of the image used to create this image.
|
||||
* `source_disk` - The URL of the source disk used to create this image.
|
||||
* `source_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 image.
|
||||
* `source_disk_id` - The ID value of the disk used to create this image.
|
||||
* `creation_timestamp` - The creation timestamp in RFC3339 text format.
|
||||
* `description` - An optional description of this image.
|
||||
* `labels` - A map of labels applied to this image.
|
||||
* `label_fingerprint` - A fingerprint for the labels being applied to this image.
|
||||
* `licenses` - A list of applicable license URI.
|
||||
* `status` - The status of the image. Possible values are **FAILED**, **PENDING**, or **READY**.
