Use dhcp and foreman proxy classes

Bardos_Matyas · September 27, 2016, 10:07am

Hello,

is it possible to use the puppets "theforeman-dhcp" and "theforeman-proxy"
on the same agent? My goal is to install and configure my dhcp server via
"theforeman-dhcp" and install/configure foreman-proxy on the same agent.
The problem is only, that class dhcp is configured in both puppets. If i
deploy both puppets on the target system, I get an error in foreman, that
class is already defined. Do you have an idea how to solve this?

Thank you!

Regards:
Matyas

Disable management of the dhcp class in foreman_proxy. See

github.com

theforeman/puppet-foreman_proxy/blob/master/manifests/config.pp#L20




# Ensure 'puppet' user group is present before managing proxy user
# Relationship is duplicated there as defined() is parse-order dependent
if defined(Class['puppet::server::install']) {
  Class['puppet::server::install'] -> Class['foreman_proxy::config']
}


if $foreman_proxy::tftp and $foreman_proxy::tftp_managed { include ::foreman_proxy::tftp }


# Somehow, calling these DHCP and DNS seems to conflict. So, they get a prefix...
if $foreman_proxy::dhcp and $foreman_proxy::dhcp_managed { include ::foreman_proxy::proxydhcp }


if $foreman_proxy::dns and $foreman_proxy::dns_managed {
  include ::foreman_proxy::proxydns
  include ::dns::params
  $groups = [$dns::params::group, $foreman_proxy::puppet_group]
} else {
  $groups = concat($foreman_proxy::groups, $foreman_proxy::puppet_group)
}


user { $foreman_proxy::user:

set foreman_proxy::dhcp_managed to false.

Dear Dominic,

thank you for your help. I have two new questions. If I would do this, does
it mean, that after the modifications, I cannot manage my dhcp server via
foreman -> foreman-proxy anymore? And the other question, where do I must
to modify this file? On the foreman server? Where is the file located on an
ubuntu server, and the modification, do I need to deploy it to the
foreman-proxy, or everything will be done automatically? Sorry, I am new in
foreman.

Thank you!

No, it just disables the foreman_proxy class including the dhcp class,
preventing the duplicate definition. You then add the dhcp class as you
did before, avoiding the duplicate.

It's a parameter of the class, you don't need to edit the module. If you
are adding the class via Foreman, edit the class under Configure >
Puppet classes, then tick Override on the dhcp_manage parameter and set
the default value to false (or set it on the host's parameters tab after
ticking Override).
