You can think “yes” because although we keep adding new features we do it in a backwards compatible manner. I personally try to be very cautious about this. > - What's the roadmap re incubation (there are a lot of TBD's here: > https://wiki.openstack.org/wiki/Mistral/Incubation) Ooh yeah, this page is very very obsolete which is actually my fault because I didn’t pay a lot of attention to this after I heard all these rumors about TC changing the whole approach around getting projects incubated/integrated. I think incubation readiness from a technical perspective is good (various style checks, procedures etc.), even if there’s still something that we need to adjust it must not be difficult and time consuming. The main question for the last half a year has been “What OpenStack program best fits Mistral?”. So far we’ve had two candidates: Orchestration and some new program (e.g. Workflow Service). However, nothing is decided yet on that. > - How does deferred authentication work for alarm triggered workflows, e.g > if a ceilometer alarm (which authenticates as a stack domain user) needs > to signal Mistral to start a workflow? It works via Keystone trusts. It works but there’s still an issue that we are to fix. If we authenticate by a previously created trust and try to call Nova then it fails with an authentication error. I know it’s been solved in other projects (e.g. Heat) so we need to look at it. > I guess a first step is creating a contrib Mistral resource and > investigating it, but it would be great if anyone has first-hand > experiences they can share before we burn too much time digging into it. Yes, we already started discussing how we can create Mistral resource for Heat. Looks like there’s a couple of volunteers who can do that. Anyway, I’m totally for it and any help from our side can be provided (including implementation itself) Renat Akhmerov @ Mirantis Inc. _______________________________________________ OpenStack-dev mailing list OpenStackemail@example.com http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
