If all you want is a script, rather than an image-building-service, then
heat has a python utility which will build an image from an oz TDL then push
it to glance:

The Cloud plugins take the resulting OS images and manage whatever needs to be done to prepare them for and push them to the cloud. If all you want is Openstack, then only install the Openstack cloud plugin. This was done precisely to decouple different areas of the code and make it easier for developers focused on a specific OS or a specific cloud to work on supporting that OS or cloud. For the user it allows imagefactory to be as focused or as flexible as needed.

I met Martyn Taylor recently at the aeolus dev-conf and we ended up
discussing the possible use-case of imagefactory for openstack.

We worked up a PoC which demonstrates the existing imagefactory OpenstackCloud
plugin capability[1] integrated  with a modified version of horizon[2], so you
can do build the image via horizon and it automagically ends up in glance.

I made an initial screencast demo, but I know Martyn is working on an
improved screencast which will soon be sent out to the lists (Martyn, added
on Cc can provide more info)

As Ian has already mentioned, there are some scalablity and performance
issues to be addressed, but it does work :)
