DNSer

Ruby DSL for create DNS Zone file

demo.zone:

template :google_app  do |host, code, params|

  TXT host, ('google-site-verification=' + code), :comment => "Google verification code"

  MX host, 'ASPMX.L.GOOGLE.COM.', priority: 1, comment: "GMail"

  TXT host, 'v=spf1 include:_spf.google.com ~all', comment: "GMail SPF"

  %w(mail doc).each do |sub|
    CNAME [sub, host].join('.'), 'ghs.googlehosted.com.'
  end
end

zone 'domain.ltd' do
  ttl 3600
  ns = NS 'ns1', 'ns1.dnsimple.com.'

  SOA host do
    nameserver ns

  end

  A IPAddr.new('127.0.0.1'), alias: :www

  A :dev, IPAddr.new('127.0.0.2')
