Designate/Blueprints/ReverseFixedIP

Overview

Gerrit Patch	[]
Launchpad Blueprint	[1]

Summary

This blueprint proposes to provide an interface for a VM instance's PTR record based on the allocated Fixed IP.

This blueprint is based on the blueprint for floating IP PTR records:

   Designate/Blueprints/Reverse

API Resource - Private / Fixed IPs

Using the general endpoint call "/reverse" add the fixed IP resource called "fixedips".

API Details

Verb	Resource	Description
GET	/reverse/fixedips	Return the list of PTR records for all fixed IP addresses.
GET	/reverse/fixedips/{region}:{IP address}	Return the PTR record for the given fixed IP address.
PATCH	/reverse/fixedips/{region}:{IP address}	Create or delete the PTR record for the given fixed IP address.

Get the PTR Record (GET)

Return the PTR record for the given IP address.

There is no request message body.

Response

   {
       “fixedip”: {
           "ptrdname": "server.mydomain.com.",
           "address": "<region>:<ipv4 or ipv6 compliant address>",
           "ttl": 3600,
           "description": null,
           "links": {
               "self": "http://endpoint/v2/reverse/fixedips/<region>:<ipv4 or ipv6 compliant address>"
           }
       }
   }

Create the PTR Record (PATCH)

Create the PTR record for the given IP address.

Request

   {
       "fixedip": {
           "ptrdname": "server.mydomain.com.",
           "ttl": 3600
       }
   }

Response

   {
       “fixedip”: {
           "ptrdname": "server.mydomain.com.",
           "address": "<region>:<ipv4 or ipv6 compliant address>",
           "ttl": 3600,
           "description": null,
           "links": {
               "self": "http://endpoint/v2/reverse/fixedips/<region>:<ipv4 or ipv6 compliant address>"
           }
       }
   }

Delete the PTR Record (PATCH)

Delete the PTR record for the given IP address.

Request

   {
       "fixedip": {
           "ptrdname": null
       }
   }

The return body is empty.

Database Changes

There are no changes to the database schema.

Implementation Notes

The Neutron API list ports call will be used.

To determine which reverse domain the IP address is use the same logic as floating IPs.
