The OS::Glance::Image resource is missing the following properties (all supported by python-glanceclient as of version 2.0.0 (that's the one I used for comparison):
--architecture <ARCHITECTURE>
Operating system architecture as specified in
http://docs.openstack.org/trunk/openstack-
compute/admin/content/adding-images.html
--visibility <VISIBILITY>
Scope of image accessibility Valid values: public,
private
--kernel-id <KERNEL_ID>
ID of image stored in Glance that should be used as
the kernel when booting an AMI-style image.
--os-distro <OS_DISTRO>
Common name of operating system distribution as
specified in http://docs.openstack.org/trunk
/openstack-compute/admin/content/adding-images.html
--owner <OWNER> Owner of the image
--ramdisk-id <RAMDISK_ID>
ID of image stored in Glance that should be used as
the ramdisk when booting an AMI-style image.
Apart from these there are two special cases:
--property <key=value>
Arbitrary property to associate with image. May be
used multiple times.
It's probably sensible to have a map attribute named `properties` or something along these lines.
--instance-uuid <INSTANCE_UUID>
Metadata which can be used to record which instance
this image is associated with. (Informational only,
does not create an instance snapshot.)
I don't think this needs to be supported in Heat, since it presents a bit of a chicken-egg problem: once you have an instance UUID to populate this property with, there already is an instance running this image.
Note: I used Heat's master branch to determine the properties missing from heat.
