[Puppet Users] Re: name resolver

[Peter Faller]

Hi Albert

Here's a custom parser function that can resolve names:

require "resolv"

module Puppet::Parser::Functions

  newfunction(
  :name2ip,
  :type => :rvalue,
  :doc => "name2ip( hostname ) => ip_address"
  ) do |arguments|
    raise(Puppet::ParseError, "name2ip(): Wrong number of arguments given 
(#{arguments.size} for 1)") if arguments.size < 1

    name = arguments[0]

    begin
      return Resolv.getaddress(name)
    rescue
      begin
        return Resolv::Hosts.new.getaddress(name)
      rescue
        raise(Puppet::Error, "Can't resolve host name '#{name}' to an IP 
address")
      end
    end
  end
end
