Google Compute Image Import Post-Processor

Type: googlecompute-import

The Google Compute Image Import post-processor takes a compressed raw disk image and imports it to a GCE image available to Google Compute Engine.

~> This post-processor is for advanced users. Please ensure you read the GCE import documentation before using this post-processor.

How Does it Work?

The import process operates by uploading a temporary copy of the compressed raw disk image to a GCS bucket, and calling an import task in GCP on the raw disk file. Once completed, a GCE image is created containing the converted virtual machine. The temporary raw disk image copy in GCS can be discarded after the import is complete.

Google Cloud has very specific requirements for images being imported. Please see the GCE import documentation for details.

Configuration

Required

account_file (string) - The JSON file containing your account credentials.
bucket (string) - The name of the GCS bucket where the raw disk image will be uploaded.
image_name (string) - The unique name of the resulting image.
project_id (string) - The project ID where the GCS bucket exists and where the GCE image is stored.

Optional

gcs_object_name (string) - The name of the GCS object in bucket where the RAW disk image will be copied for import. Defaults to "packer-import-{{timestamp}}.tar.gz".
image_description (string) - The description of the resulting image.
image_family (string) - The name of the image family to which the resulting image belongs.
image_labels (object of key/value strings) - Key/value pair labels to apply to the created image.
keep_input_artifact (boolean) - if true, do not delete the compressed RAW disk image. Defaults to false.
skip_clean (boolean) - Skip removing the TAR file uploaded to the GCS bucket after the import process has completed. "true" means that we should leave it in the GCS bucket, "false" means to clean it out. Defaults to false.

Basic Example

Here is a basic example. This assumes that the builder has produced an compressed raw disk image artifact for us to work with, and that the GCS bucket has been created.

{
  "type": "googlecompute-import",
  "account_file": "account.json",
  "project_id": "my-project",
  "bucket": "my-bucket",
  "image_name": "my-gce-image"
}

QEMU Builder Example

Here is a complete example for building a Fedora 28 server GCE image. For this example packer was run from a CentOS 7 server with KVM installed. The CentOS 7 server was running in GCE with the nested hypervisor feature enabled.

$ packer build -var serial=$(tty) build.json
