----------------

|

Fuel Master Node:
|
||||
**/etc/cobbler/dnsmasq.template**
|
||||
|
||||
The *dnsmasq.template* file defines the DHCP networks
|
||||
used for :ref:`Multiple Cluster Networks<mcn-arch>`.
|
||||
The networks listed here must match
|
||||
the `fuelweb_admin` networks that are defined in Fuel.
|
||||
|
||||
Usage
|
||||
~~~~~
|
||||
|
||||
#. Log into the cobbler :ref:`docker-term` container:
|
||||
::
|
||||
|
||||
dockerctl shell cobbler
|
||||
|
||||
#. Edit file.
|
||||
::
|
||||
|
||||
vi /etc/cobbler/dnsmasq.template
|
||||
|
||||
#. Rebuild the dnsmasq configuration and reload it:
|
||||
::
|
||||
|
||||
cobbler sync
|
||||
|
||||
|
||||
#. Exit the Cobbler docker container:
|
||||
::
|
||||
|
||||
exit
|
||||
|
||||
File Format
|
||||
~~~~~~~~~~~
|
||||
|
||||
Each `fuelweb_admin` network must be defined in this file:
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
dhcp-range=<name>,<start-IP-addr>,<end-IP-addr>,<netmask>,[<leasetime>]
|
||||
dhcp-option=net:<name>,option:router,<IP-addr-of-gateway>
|
||||
dhcp-boot=net:<name>,pxelinux.0,boothost,<Fuel-Master-IP-addr>
|
||||
|
||||
:env-name: Unique name of this network in **dnsmasq**
|
||||
|
||||
:start-IP-addr: Starting IP address of DHCP range
|
||||
|
||||
:end-IP-addr: Ending IP address of DHCP range
|
||||
|
||||
:netmask: Netmask for DHCP network
|
||||
|
||||
:leasetime: DHCP lease time; default value is 60 minutes
|
||||
|
||||
:IP-addr-of-gateway: IP address of gateway (router) in the network segment
|
||||
|
||||
:Fuel-Master-IP-addr: IP address of the Fuel Master node
|
||||
|
||||
For example:
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
dhcp-range=alpha,10.110.1.68,10.110.1.127,255.255.255.192,120m
|
||||
dhcp-option=net:alpha,option:router,10.110.1.65
|
||||
dhcp-boot=net:alpha,pxelinux.0,boothost,10.110.0.2
|
||||
|
||||
The network must forward the DHCP packets for the other logical
|
||||
networks that are defined in the
|
||||
:ref:`network_1.yaml<network-1-yaml-ref>` file.
|
||||
It is also possible to set up a proxy using
|
||||
the Linux **dhcp-helper** program
|
||||
so that the target nodes can boot.
|
||||
|
||||
Note that the *dnsmasq.template* file is managed
|
||||
by :ref:`Puppet<puppet-term>`
|
||||
so all changes are overwritten/removed when the Puppet container is restarted
|
||||
or the Fuel Master node is rebooted.
