[Fuel] [Nailgun] Rolling Fuel upgrades

 

Hi, fuelers.

We are started evaluating the PoC implementation for Fuel upgrading
https://blueprints.launchpad.net/fuel/+spec/fuel-upgrade.

Please don't hesitate to give us any feedback on the following
architectural considerations
https://etherpad.openstack.org/p/nailgun-unified-object-model

Basically, the idea is to design the "unified object model" for Fuel as
well (see
https://blueprints.launchpad.net/nova/+spec/unified-object-model as Nova
example). That would allow us to introduce the versioned objects in
Nailgun and to simplify the upgrading process for Fuel master node as
well as for deployed Mirantis Openstack environments.

If there are any similar blueprints already exist, please let me know to
update them appropriately. If not, the first action I suggest to do is
to link this blueprint as a dependency for
https://blueprints.launchpad.net/fuel/+spec/fuel-upgrade.
