  2. Files [ '/etc/powerdns/bindbackend.conf', '/etc/powerdns/pdns.d/pdns.simplebind.conf', '/etc/powerdns/pdns.d/pdns.local.conf', ]

• Is very important to know about PowerDNS to use this Puppet module.

Beginning with ::powerdns

You can use

node 'dns.mynetwork.local' {
  include ::powerdns
  include ::powerdns::backend
}

or

node 'dns.mynetwork.local' {
  class { '::powerdns': }
  class { '::powerdns::backend': }
}

to install and configure PowerDNS with Default module parameters.

additional you could use

node 'dns.mynetwork.local' {
  include ::powerdns::recursor
}

or

node 'dns.mynetwork.local' {
  class { '::powerdns::recursor': }
}

if you want to configure PowerDNS Recursor service.

Usage

For more specific configuration of powerdns class you can use:

node 'dns.mynetwork.local' {
  class { '::powerdns':
    package_ensure     => 'present',
    service_enable     => true,
    service_ensure     => 'running',
    service_status     => true,
    service_status_cmd => '/usr/bin/pdns_control ping 2>/dev/null 1>/dev/null',
    config => {
      'allow-from'      => '192.168.1.0/24',
      'local-port'      => 53,
      'query-cache-ttl' => 20,
    }
  }
}

To configure PostgreSQL as backend, you can do: NOTE: See valid backend name in param file before to set variable backend_name this depend of the Operating System type

node 'dns.mynetwork.local' {
  class { '::powerdns::backend':
    backend_name => 'pgsql',
    ensure       => 'present',
    config       => {
      'launch'          => 'gpgsql',
      'gpgsql-host'     => 'localhost',
      'gpgsql-port'     => '3306',
      'gpgsql-dbname'   => 'mypdnsdb',
      'gpgsql-user'     => 'mypdnsuser',
      'gpgsql-password' => 'mypassword',
    }
  }
}

For more specific configuration of PowerDNS Recursor class you can use:

node 'dns.mynetwork.local' {
  class { '::powerdns::recursor':
    package_ensure     => 'present',
    service_enable     => true,
    service_ensure     => 'running',
    service_status     => true,
    service_status_cmd => '/usr/bin/rec_control ping 2>/dev/null 1>/dev/null',
    config => {
      'allow-from'                 => '192.168.1.0/24',
      'local-port'                 => 53,
      'etc-hosts-file'             => '/etc/hosts',
    }
  }
}

Limitations

• This module could not manage DNS records, this only can be used as configuration of PowerDNS.
• If you change backend type, it doesn't remove your old backend file config from the /etc/[pdns|powerdns]/pdns.d/pdns.local.[backend type].conf, so is neccesay that you remove it after change the backend type to use the new backend.
