Bug Description
When managing large groups of OS::Nova::Server resources inside e.g a ResourceGroup, you may want to change a property such that it only affects new instances of the resource.
Examples:
- adding node-specific data to a mapping written via user_data
- Changing the image to point to a new version, existing nodes are updated in-place
Currently we have image_update_
For the first example, we need a user_data_
The use-case for this is allowing non-destructive stack updates for TripleO, but it's a general problem for maintaining large groups of servers over a long period of time, where a forced replacement or even rolling update are not desired.
