DHCP module for Puppet

Installs and manages a DHCP server.

Features

• Multiple subnet support
• Host reservations
• Secure dynamic DNS updates when combined with Bind
• Can create a dummy (ignored) subnet so that the server can be used only as a helper-address target

Usage

Define the server and the zones it will be responsible for.

class { 'dhcp':
  dnsdomain    => [
    'dc1.example.net',
    '1.0.10.in-addr.arpa',
    ],
  nameservers  => ['10.0.1.20'],
  ntpservers   => ['us.pool.ntp.org'],
  interfaces   => ['eth0'],
  dnsupdatekey => "/etc/bind/keys.d/$ddnskeyname",
  require      => Bind::Key[ $ddnskeyname ],
  pxeserver    => '10.0.1.50',
  pxefilename  => 'pxelinux.0',
}

dhcp::pool

Define the pool attributes

dhcp::pool{ 'ops.dc1.example.net':
  network => '10.0.1.0',
  mask    => '255.255.255.0',
  range   => '10.0.1.100 10.0.1.200',
  gateway => '10.0.1.1',
}

dhcp::ignoredsubnet

Define a subnet that will be ignored - useful for making the DHCP server only respond to requests forwarded by switches etc.

dhcp::pool{ 'eth0':
  network => '10.0.0.0',
  mask    => '255.255.255.0',
}

dhcp::host

Create host reservations.

dhcp::host {
  'server1': mac => "00:50:56:00:00:01", ip => "10.0.1.51";
  'server2': mac => "00:50:56:00:00:02", ip => "10.0.1.52";
  'server3': mac => "00:50:56:00:00:03", ip => "10.0.1.53";
}
