Open Stack

I wanted to bring this up for awareness since we're getting close to 
feature freeze and want consensus before it gets too late.

Ken'ichi brought up a good question on my REST API change for the 2.37 
microversion:

https://review.openstack.org/#/c/316398/

The way I had written this was to just add special auto/none values for 
the networks 'uuid' field in the server create request schema.

The catch with using auto/none is that they can't be specified with any 
other values, like other networks, or a port, or really anything else. 
It's just a list with a single entry and that's either uuid=auto or 
uuid=none.

Ken'ichi's point was, why not just make "networks" in this case map to 
'auto' or 'none' or the list that exists today.

I like the idea, it's cleaner and it probably allows moving some of the 
validation from the REST API code into the json schema (I think, not 
totally sure about that yet).

It is a change for how networks are requested today so there would be 
some conditional logic change pushed on the client - my tempest test 
change and novaclient changes would have to be updated for sure.

So I'm looking for input on that idea before we get too late, is that 
difference worth the work and syntax change in how the client requests a 
network when creating a server?
