Is it possible to add Swift to a Microstack Installation?
I’m searching for a Swift-Installation with Keystone V3 Authentication for development and testing.
The zen of microstack is to be on rails, and unfortunately I don’t think the rails will go there 
By which I mean I don’t think it would make sense to add Swift to the Microstack snap directly. It might make sense to have a microswift snap which does just Swift, which you could lay down on machines alongside microstack, but I don’t know about integration of those two.
When it comes to mixing and matching services in an OpenStack architecture, you can’t beat charms, but there is a learning curve associated with that which is much greater than the micro-fu approach.
