The `GCE <https://cloud.google.com/products/compute-engine/>`__ provider
can creates image as expected by GCE - i.e. raw disk image in \*.tar.gz
file. It can upload created images to Google Storage Engine (to URI
provided in manifest by ``gcs_destination``) and can register image to
be used by Google Compute Engine to project provided in manifest by
file. It can upload created images to Google Cloud Storage (to a URI
provided in the manifest by ``gcs_destination``) and can register images to
be used by Google Compute Engine to a project provided in the manifest by
``gce_project``. Both of those functionalities are not fully tested yet.
Note that to register an image, it must first be uploaded to GCS, so you must
specify ``gcs_destination`` (upload to GCS) to use ``gce_project`` (register
with GCE)
