puppet-resolvconf

Overview

Manage /etc/resolv.conf with puppet.

• resolvconf : Main class.
• resolvconf::file : Definition to manage extra files.

The idea is to be able to globally include the resolvconf class on all nodes. From there, hiera with puppet 3.x allows to start managing the /etc/resolv.conf file's content in a very flexible way.

Examples

In site.pp :

hiera_include('classes')

In hieradata somewhere :

---
classes:
  - '::resolvconf'
resolvconf::header: ''
resolvconf::nameserver:
  - '198.51.100.1'
  - '198.51.100.2'
resolvconf::search:
  - 'foo.example.com'
  - 'bar.example.com'
  - 'example.com'

This way, only nodes where the Hiera values apply get their /etc/resolv.conf file modified by Puppet.

Ubuntu allows for file snippets to be used :

resolvconf::file { '/etc/resolvconf/resolv.conf.d/tail':
  nameserver => [ '198.51.100.1', '198.51.100.2' ],
}
