DHCP module for theforeman. Based on original DHCP module by ZLeslie, thanks to him for the original work.
Installs and manages a DHCP server.
- Multiple subnet support
- Support for multiple pools within a subnet
- Host reservations
- Secure dynamic DNS updates when combined with Bind
- Failover support
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'],
interfaces => ['eth0'],
dnsupdatekey => "/etc/bind/keys.d/$ddnskeyname",
require => Bind::Key[ $ddnskeyname ],
pxeserver => '10.0.1.50',
pxefilename => 'pxelinux.0',
}
To create a subnet with a single pool, use 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',
}
Override global attributes with pool specific
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',
nameservers => ['10.0.1.2', '10.0.2.2'],
pxeserver => '10.0.1.2',
}
For the support of static routes (RFC3442):
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 => $gw,
static_routes => [ { 'mask' => '32', 'network' => '169.254.169.254', 'gateway' => $ip },
{ 'mask' => '0', 'gateway' => $gw } ],
}
To create a subnet with multiple pools, use dhcp::subnet.
dhcp::subnet{ 'ops.dc1.example.net':
network => '10.0.1.0',
mask => '255.255.255.0',
pools => [
{
range => '10.0.1.101 10.0.1.110',
parameters => [
'allow members of "group1"',
'next-server 10.1.1.1',
],
},
{
range => '10.0.1.111 10.0.1.120',
parameters => [
'allow members of "group2"',
'next-server 10.1.1.2',
],
},
],
gateway => '10.0.1.1',
}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";
}
