7.1. DHCP Management
Cobbler can optionally help you manage a DHCP server. This feature is disabled by default.
The following options are available for modules.dhcp.module
:
"managers.isc"
"managers.dnsmasq"
Set manage_dhcp: true
and manage_dhcp_v4
or manage_dhcp_v6
to true
for this setting to take effect.
This allows DHCP to be managed via “cobbler system add” commands, when you specify the MAC address and IP address for systems you add into Cobbler.
You must configure the templates for your networking environment. Read the file and understand how the particular app works before proceeding.
If you already have DHCP configuration data that you would like to preserve (such as DHCP that was manually configured earlier),
insert the relevant portions of it into the template file, as running cobbler sync
will overwrite your previous
configuration.
By default, Cobbler updates the DHCP configuration file each time you run cobbler sync
.
Remember to use cobbler sync
when you use this feature.
