## Overview
Manage the `/etc/resolv.conf` on Linux and FreeBSD.
## Module Description
The module manages the DNS resolver configuration file. It allows setting the values for the `nameserver`, `search`, `sortlist` and `options` configuration settings. The following restrictions are enforced by the module:
* Up to 3 name servers may be listed.
* Up to 6 items may be included in the search list.
* Up to 10 items may be included in the sortlist.
## Setup
### What resolv_conf affects
The module creates and manages the content of the `/etc/resolv.conf` file. This affects the way the host is able to map hostname to IP addresses and vice versa.
### Setup Requirements
The module uses the Puppet `stdlib` module.
### Beginning with resolv_conf
Declare the class to create a configuration that uses only a local name server on `127.0.0.1`.
```puppet
class { 'resolv_conf': }
```
## Usage
You can use class parameters to use a customized configuration.
```puppet
class { 'resolv_conf':
nameservers => [ '9.9.9.9', ],
}
```
You can also use Hiera to create this configuration.
```
resolv_conf::nameservers:
- '9.9.9.9'
```
### Specify a remote name server and use local domain for unqualified hostnames
The following configuration will configure a remote name server and use the name of the local domain when unqualified hostnames are queried.
```puppet
class { 'resolv_conf':
nameservers => [ '9.9.9.9', ],
searchlist => [ $facts['networking']['domain'] ],
}
```
If your host is based in the `example.net` domain, then a lookup for the hostname `server` will query the name server for `server.example.net`.
### Specify name servers & options
This setup creates a configuration file with the given name servers and will also set additional options to enable name server rotation and set a specific timeout.
```puppet
class { 'resolv_conf':
nameservers => [ '8.8.8.8', '8.8.4.4', ],
options => [ 'rotate', 'timeout:2', ],
}
```
### Prefer a local name server
The following setup will create a configuration where the name server at `127.0.0.1 ` is queried first and only then the additional name servers are used.
```puppet
class { 'resolv_conf':
nameservers => [ '8.8.8.8', '8.8.4.4', ],
prepend_local_nameserver => true,
}
```
**Note**: This module does not configure a local name server that will answer queries on `127.0.0.1`. You will have to use a different Puppet module to manage the name server.
