Kmod Puppet module

Puppet Forge Version Puppet Forge Downloads Build Status Puppet Forge Endorsement Donated by Camptocamp

Description

This module provides definitions to manipulate modprobe.conf (5) stanzas:

  • kmod::alias
  • kmod::install
  • kmod::blacklist

It depends on Augeas with the modprobe lens.

Usage

This module has five main defined types:

  • kmod::load
  • kmod::alias
  • kmod::option
  • kmod::install
  • kmod::blacklist

kmod::load

Loads a module using modprobe and manages persistent modules in /etc/sysconfig/modules

  kmod::load { 'mymodule': }

kmod::alias

Adds an alias to modprobe.conf, by default /etc/modprobe.d/<name>.conf is assumed for a filename.

  kmod::alias { 'bond0':
    aliasname => 'bonding',
  }

Params:

  • modulename: Name of the module to alias
  • aliasname: Name of the alias (defaults to the resource title)
  • file: File to write to (see above default)

kmod::option

Adds an option to modprobe.conf

  kmod::option { 'bond0 mode':
    module  => 'bond0',
    option  => 'mode',
    value   => '1',
  }

  kmod::option { 'bond0':
    option => 'mode',
    value  => '1',
  }

Params:

  • option: Name of the parameter to add
  • value: Value of the parameter
  • module: Name of the module (if ommited, the resource title is used)
  • file: File to write to (defaults to /etc/modprobe.d/<module name>.conf)

kmod::blacklist

Manages modprobe blacklist entries. Blacklist entries prevents module aliases from being used, but would not prevent the module from being loaded. To prevent a module from being loaded use kmod::install

  kmod::blacklist { 'foo': }

Params:

  • file: File to write to, defaults to /etc/modprobe.d/blacklist.conf

kmod::install

Manage modprobe install entries

   kmod::install { 'pcspkr': }

If you want to ensure that module can't be loaded at all you can do the following:

   kmod::install { 'dccp': command => '/bin/false' }

Params:

  • file: File to write to (defaults to /etc/modprobe.d/<module name>.conf)
  • command: (optional) command associated with the install, defaults to /bin/true

Using the module with hiera

The module makes available lists for every defined type that will create those defined types if defined as class parameters. The parameters are:

  • kmod::list_of_blacklists:
  • kmod::list_of_aliases:
  • kmod::list_of_installs:
  • kmod::list_of_loads:
  • kmod::list_of_options:

Example usage:

---
kmod::list_of_blacklists:
  'foo01': {}
  'foo02': {}
  'foo03': {}
kmod::list_of_aliases:
  'foo01':
    source: 'squashfs'
    aliasname: 'squash01'
  'foo02':
    source: 'squashfs'
    aliasname: 'squash02'
kmod::list_of_installs:
  'dccp':
    command: '/bin/false'
  'blah':
    command: '/bin/true'
kmod::list_of_loads:
  'cramfs': {}
  'vfat': {}
kmod::list_of_options:
  'bond0 mode':
    module: 'bond0'
    option: 'mode'
    value: '1'
  'bond0':
    option: 'mode'
    value: '1'
