Please note: This schedule is for OpenStack Active Technical Contributors participating in the Icehouse Design Summit sessions in Hong Kong. These are working sessions to determine the roadmap of the Icehouse release and make decisions across the project. To see the full OpenStack Summit schedule, including presentations, panels and workshops, go to http://openstacksummitnovember2013.sched.org.
This session will include the following subject(s):
Healing and convergence:
It may be useful for Heat to have a mechanism for self-healing and/or convergence. i.e., if an underlying resource disappears or goes into an error state for whatever reason, it would be nice for Heat to have a mechanism to fix or delete/recreate the underlying resource, either explicitly through user action ("heat converge") or implicitly (based on a schedule?)
(Session proposed by Christopher Armstrong)
Support API retry function with Idempotency:
I suggest the implementation of retry function as a countermeasure for the failures of API calls to nova, cinder, etc.. when creating/updating a stack in Heat. In order to avoid the overlapped resource allocations, the proposed retry function supports Idempotency in API calls. By adding this function, the likelihood of success in creating/updating of the entire stack by one call will be increased. Please see the following Blue print for more information.
