The original intention was to propose the Heater functionality as part of Heat. I would just like to clarify that having Heater as a separate project is not because of the impact of the gerrit reviews. The proposal for a separate Core team or sub-project team was to solve the impact on reviews. Heater is now being proposed as a separate project from Heat because previous conversations with the Heat Core team has lead us to believe that Heat is not in the business of managing templates.

I’d also suggest the Heater guys talk to the Murano guys since my ideal scenario is for a simple user kiosk where I can ask for an app, be asked for some configuration details and then deploy. The two projects appear to be heading towards a converged solution.

One thing I would like to point out is that we get feedback that OpenStack has too many projects as it is and customers get confused on how much of OpenStack they need to install. So in the spirit of trying to help insure OpenStack does not continue to reinforce this perception, I am hoping that Heater functionality finds a home in either Glance or Heat. I don't have a preference of which. Either of these is superior to starting a new project if it can be avoided.

Fitting is one thing, optimizations around particular assumptions about the size of data and the frequency of reads/writes might be an issue, but I admit to ignorance about those details in Glance. > 2: The swift API supports versions.

Agreed, though one could argue that using image names and looking up ID's or just using ID's as appropriate "sort of" handle this use case, but I agree that having image versioning seems a reasonable feature for Glance to have as well. > 3: I'm sure glance image users would love to have those too.

I'd been thinking of adding the tenancy/public/private templates use case to the HeatR spec and realized that this was a good argument for Glance since it already has this feature. > It strikes me that this might be a silo problem instead of an > actual design problem.

(adding glance tag to the subject) Perhaps, and if these use cases make sense for the Glance users in general, I wouldn't want to re-invent all those wheels either. I admit there's some appeal to being able to pass a template ID to stack-create or as the type of a provider resource and have an actual API to call that's already got a known, tested client that's already part of the OpenStack ecosystem In the end, though, even if some and not all of our use cases make sense for the Glance folks, we still have the option of creating the HeatR service and having Glance as a possible back-end data store. > _______________________________________________ > OpenStack-dev mailing list > OpenStack-dev@lists.openstack.org<mailto:OpenStack-dev@lists.openstack.org> > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org<mailto:OpenStack-dev@lists.openstack.org> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
