powerdns-cloudstack-console-proxy-dns

PowerDNS Lua script to provide realhostip.com like feature for cloudstack and others

Installation

  1. First, make sure to have Lua enabled in your PowerDNS authorative server. If you are using a RHEL based distribution with EPEL you could probably do something like yum install pdns-backend-lua

  2. Place the cloudstack-dns.lua file somewhere where your powerdns can access and read it. Ie. in your /etc/pdns folder.

Configuration

  1. In your pdns.conf, add lua to launch after your existing backends.

  2. If this is a dedicated domain, you have to provide NS and SOA records as you normally would, as that's outside the scope of this script.

  3. If you are using the bind backend, your pdns.conf should look like this:

launch=bind,lua
lua-filename=/etc/pdns/cloudstack-dns.lua
  1. In cloudstack-dns.lua, specify the domain variable. This will be configurable from pdns.conf once that works, but is hard coded as a workaround

Testing

[vagrant@pdns ~]$ dig +short 1-2-3-4.realhostip.com @localhost
1.2.3.4
