Description James Slagle 2018-08-29 21:05:30 UTC
This feature will allow for deploying separate stacks in Director with the stacks split between control plane services and compute/storage services.

We'll need to be more specific at a later date around which services are exactly part of which stack. The initial thinking is that any non-API tenant consumed resource such as compute or storage resources would be separated in the compute stack.

This feature is commonly referred to as "split-controlplane".

There exists an initial upstream blueprint:


As well as several existing patches that make this possible within tripleo-heat-templates today:


My initial notes on how to use the above 3 patches are at:

Remaining work items would include any API support via workflows and any CLI/UI support.

Additionally, there are upgrade impacts to consider as there are dependencies between the stacks.
