OpenStack Floating IPs API (draft)

Launchpad Entry: NovaSpec:openstack-api-floating-ips
Created:
Contributors: Ilya Alekseyev, Eldar Nugaev, Kirill Shileev

Summary

Our goal is to add support for floating ips management in OpenStack API.

Release Note

Support for floating ips management in OpenStack API.

Rationale

User stories

Eldar wants to associate additional IP with instance. He should to have possibility to associate address. Then he wants to disassociate address. He also should have such possibility.

Assumptions

Design

At this moment we have implementation of floating IP in EC2 API. That contains next command

allocate_address
release_address
associate_address
disassociate_address

verb	URI	Request	Response
POST	/floating_ips/	n/a
GET	/floating_ips/	n/a
GET	/floating_ips/{ip}	n/a
GET	/floating_ips/{ip_id}	n/a
DELETE	ip_id}	n/a
POST	ip_id}/disassociate	n/a
POST	ip_id}/associate	fixed ip

List of floating IPs

Response XML

<floating_ips>
    <floating_ip>
        <id>1</id>
        <ip>10.0.0.3</ip>
    </floating_ip>
</floating_ips>

Response JSON

{
    "floating_ips" : [
        {
            "id" : 1,
            "ip" : "10.0.0.3"
        }
    ]
}

Floating IP details

Response XML

<floating_ip>
    <id>1</id>
    <ip>10.0.0.3</ip>
    <fixed_id>null</fixed_ip>
    <instance_id>null</instance_id>
</floating_ip>

Response JSON

{
    "floating_ip" : 
        {
            "id" : 1,
            "ip" : "10.0.0.3",
            "fixed_ip" : null,
            "instance_id" : null
        }
}

Associate address

Request XML

<?xml version="1.0" encoding="UTF-8"?>
<associate_address>
    <fixed_ip>10.0.0.3</fixed_ip>
</associate_address>

Request JSON

{
    "associate_address" : {
       "fixed_ip":"10.0.0.3"
    }
}

Implementation

Add such methods to OS API.

Code Changes

Implementation for autoassociation floating ip was added in http://bazaar.launchpad.net/~hudson-openstack/nova/trunk/revision/1025

BoF agenda and discussion

Add information about floating IP in server details.

-=== Migration ===
-Include:
-* data migration, if any
-* redirects from old URLs to new ones, if any
-* how users will be pointed to the new way of doing things, if necessary.
-== Test/Demo Plan ==
-This need not be added or completed until the specification is nearing beta.
-== Unresolved issues ==
-This should highlight any issues that should be addressed in further specifications, and not problems with the specification itself; since any specification with problems cannot be approved.
 == BoF agenda and discussion ==
-Use this section to take notes during the BoF; if you keep it in the approved spec, use it for summarising what was discussed and note any options that were rejected.
