OpenStack Heat

API for adjusting the size of a scaling group

Registered by Christopher Armstrong

In order to factor out the autoscaling functionality into a separate service (and to potentially support other use cases such as manual scale-up/scale-down by an administrator), there needs to be an API exposed to add or remove instances from a scaling group (InstanceGroup).

PUT .../resources/<group>/adjust was proposed, but this may not be very ReSTy -- perhaps PUT .../resources/<group>/group-size would be more in the spirit of ReST?

The body could look like:

{
    "adjustment": <int>,
    "adjustment_type": <string>
}

where "adjustment_type" is one of "ChangeInCapacity", "ExactCapacity", or "PercentageChangeInCapacity".

closing this for now. I don't think we'll need this in the end. More discussion to be had.
