This module configures the Resolv file.

Module Description

This module handles configuring Resolv across a range of operating systems and distributions.

Setup

What resolv affects

• resolv configuration file.

Setup Requirements

• Puppet >= 3.0
• Facter >= 1.6
• Extlib module
• Stdlib module

Beginning with resolv

Install resolv with the default parameters (No configuration files will be changed).

    class { 'resolv': }

Install resolv with the recommended parameters.

    class { 'resolv':
      config_file_template => 'resolv/common/etc/resolv.conf.erb',
    }

Usage

Update the resolv package.

    class { 'resolv':
      package_ensure => 'latest',
    }

Remove the resolv package.

    class { 'resolv':
      package_ensure => 'absent',
    }

Purge the resolv package (All configuration files will be removed).

    class { 'resolv':
      package_ensure => 'purged',
    }

Deploy the configuration files from source directory.

    class { 'resolv':
      config_dir_source => 'puppet:///modules/resolv/common/etc',
    }

Deploy the configuration files from source directory (Unmanaged configuration files will be removed).

    class { 'resolv':
      config_dir_purge  => true,
      config_dir_source => 'puppet:///modules/resolv/common/etc',
    }

Deploy the configuration file from source.

    class { 'resolv':
      config_file_source => 'puppet:///modules/resolv/common/etc/resolv.conf',
    }

Deploy the configuration file from string.

    class { 'resolv':
      config_file_string => '# THIS FILE IS MANAGED BY PUPPET',
    }

Deploy the configuration file from template.

    class { 'resolv':
      config_file_template => 'resolv/common/etc/resolv.conf.erb',
    }

Deploy the configuration file from custom template (Additional parameters can be defined).

    class { 'resolv':
      config_file_template     => 'resolv/common/etc/resolv.conf.erb',
      config_file_options_hash => {
        'key' => 'value',
      },
    }

Deploy additional configuration files from source, string or template.

    class { 'resolv':
      config_file_hash => {
        'resolv.2nd.conf' => {
          config_file_path   => '/etc/resolv.2nd.conf',
          config_file_source => 'puppet:///modules/resolv/common/etc/resolv.2nd.conf',
        },
        'resolv.3rd.conf' => {
          config_file_path   => '/etc/resolv.3rd.conf',
          config_file_string => '# THIS FILE IS MANAGED BY PUPPET',
        },
        'resolv.4th.conf' => {
          config_file_path     => '/etc/resolv.4th.conf',
          config_file_template => 'resolv/common/etc/resolv.4th.conf.erb',
        },
      },
