.. _datasource_gce: Google Compute Engine ===================== The GCE datasource gets its data from the internal compute metadata server. Metadata can be queried at the URL '``http://metadata.google.internal/computeMetadata/v1/``' from within an instance. For more information see the `GCE metadata docs`_. Currently the default project and instance level metadatakeys keys ``project/attributes/sshKeys`` and ``instance/attributes/ssh-keys`` are merged to provide ``public-keys``. ``user-data`` and ``user-data-encoding`` can be provided to cloud-init by setting those custom metadata keys for an *instance*. .. _GCE metadata docs: https://cloud.google.com/compute/docs/storing-retrieving-metadata#querying .. vi: textwidth=78
