Services Framework for Command and Control

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

The services framework from nova is in the process of being moved into openstack-common. I'd like to propose the following additions to the services framework to make it more useful:
* Signal Handling
--HUP to reload configs
--TERM die as soon as threads are finished
* Command and Control over RPC:
Pause (stop consuming regular queue messages)
Resume (continue consuming regular queu messages)
Reload (reload configs and continue)
Restart (run a new copy of the daemon and terminate this one)
* Potential Command and Control:
ChangeConfigOption (does it change the on disk config or just the running one?)
StartPaused (start a new copy of the code Paused, requires running simultaneous code)
SoftTerminate (terminate the instance when threads are finished)
NOTE: The last two could be useful for the following strategy:
a) StartPaused
b) Pause (this one)
c) Resume (new one)
d) SoftTerminate(this one)
