Description

Get and set parameters of NetworkManager controlled connections.

In the first iteration this module supports management of two aspects of the NetworkManager:

• Management of the NetworkManager daemon - whther it is running and enabled or not
• Management of DNS information of particular NetworkManager connections. This could be done on three different ways:
  • Either by configurig a global Configuration file below /etc/NetworkManager/conf.d,
  • or by setting the DNS parameters of the primary NetworkManager connection (whichever it is),
  • or by setting the DNS parameters of one or more named NetworkManager connections.

Setup

Setup Requirements

This module requires following:

• Puppet >= 6.0
• the module puppetlabs-stdlib >= 7.0.0

This module ist supported only for operating systems using NetworkManager. If the NetworkManager command line tool nmcli could not be found, the module fails immediately.

This module was currently tested on:

• CentOS-7 and CentOS-8
• Oracle Enterprise Linux 7

Usage

Simple Including the module

The following two examples are simply including the networkmanager module. The further configuration must be done via hieradata.

include networkmanager

or

contain networkmanager

Instantiation as a class

The following example is instatiating this module class with nearly all parameters:

class {'networkmanager':
    enable_global_dns     => false,
    manage_dns            => true,
    nameservers           => ['8.8.8.8', '8.8.4.4', '1.1.1.1'].
    dns_searchdomains     => ['example.com', 'uhu-banane.de', 'uhu-banane.net'],
    dns_options           => ['timeout:1', 'attempts:2', 'use-vc'],
    manage_service        => true.
    ensure_service        => running,
    enable_service        => true,
    dns_notify_daemon     => false,
    connection_dnsoptions => {
      wifi1               => {
        nameservers       => ['172.28.1.2', '172.30.1.2'],
        searchdomains     => ['home.example.com'],
        dns_options       => ['timeout:3, 'attempts:3', 'use-vc'],
        notify_daemon     => true,
      },
    },
}

Setup of hieradata

All parameters of the networkmanager module could be configured as hieradata. But be aware, that all parameters are looked up with a first lookup. If you want to make a deep lookup, yu have to set the lookup options by yourself.

---
networkmanager::enable_global_dns: false
networkmanager::manage_dns: true
networkmanager::nameservers:
  - '8.8.8.8'
  - '8.8.4.4'
  - '1.1.1.1'
networkmanager::dns_searchdomains:
  - 'example.com'
  - 'uhu-banane.de'
  - 'uhu-banane.net'
networkmanager::dns_options:
  - 'timeout:1'
  - 'attempts:2'
  - 'use-vc'
networkmanager::manage_service: true
networkmanager::ensure_service: running
networkmanager::enable_service: true
networkmanager::dns_notify_daemon: false
networkmanager::connection_dnsoptions:
  wifi1:
    nameservers:
      - '172.28.1.2'
      - '172.30.1.2'
    searchdomains:
      - 'home.example.com'
    dns_options:
      - 'timeout:3'
      - 'attempts:3'
      - 'use-vc'
    notify_daemon: true

Parameters

Limitations

The development of this module has even started, so the amount on functionality is not so giant.
