Certainly. Please add a blueprint for that and I'll mark itup appropriately. Related to that we had a long chat in IRC that I was to follow up here, so - ... Tuskar is refocusing on getting the basics really right - slick basic install, and then work up. At the same time, just about every nova person I've spoken too (a /huge/ sample of three, but meh :)) has expressed horror that Tuskar is doing it's own scheduling, and confusion about the need to manage flavors in such detail. So the discussion on IRC was about getting back to basics - a clean core design and something that we aren't left with technical debt that we need to eliminate in order to move forward - which the scheduler stuff would be. So: my question/proposal was this: lets set a couple of MVPs. 0: slick install homogeneous nodes: - ask about nodes and register them with nova baremetal / Ironic (can use those APIs directly) - apply some very simple heuristics to turn that into a cloud: - 1 machine - all in one - 2 machines - separate hypervisor and the rest - 3 machines - two hypervisors and the rest - 4 machines - two hypervisors, HA the rest - 5 + scale out hypervisors - so total forms needed = 1 gather hw details - internals: heat template with one machine flavor used 1: add support for heterogeneous nodes: - for each service (storage compute etc) supply a list of flavors we're willing to have that run on - pass that into the heat template - teach heat to deal with flavor specific resource exhaustion by asking for a different flavor (or perhaps have nova accept multiple flavors and 'choose one that works'): details to be discussed with heat // nova at the right time. 2: add support for anti-affinity for HA setups: - here we get into the question about short term deliverables vs long term desire, but at least we'll have a polished installer already. -Rob -- Robert Collins <rbtcoll...@hp.com> Distinguished Technologist HP Converged Cloud _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
