Open Stack

Perhaps I misunderstood. I thought option #3 consisted of adding new http resources to the openstack api to expose the add/allocate/associate/etc floating ip functionality to the api consumer.
 
If that is the case, I believe it would be a break with the cloud servers 1.0 api, where a customer would expect to get a public ip for free when they create an instance.

I like the simple solution (#3) as well.
It gets parity for the APIs while leaving more advanced topics for the NaaS discussions.

Appears my response got lost somehow. I vote for #3 as it's the most configurable (and affects nothing contrariwise). In addition to believing we use flags too often, I don't think having a flag solves the problem very well. A couple of examples show why:
you want a few instances having floating IP(s) while others do not
you want multiple floating IPs for an instance

Mark,

approach #1 implementation is here: [https://code.launchpad.net/%7Eopenstack-gd/nova/auto-float-ip] https://code.launchpad.net/~openstack-gd/nova/auto-float-ip. I saw that you interested in approach #3 too. May be you have some ideas of specification of API for approach #3?
 
Erik,
there is implementation of floating ips in Nova. In implementation of approach #1 we just care about auto assigning/deassigning. As I know floating ip implemented like NAT from network nodes.

Eldar,

I'm having some trouble finding the diff for your implementation of approach #1. Any chance you can share it on the list?

Thanks
