Documentation

For default types (users, groups, mounts, yumrepos, packages, cron, exec) see the documentation at http://docs.puppetlabs.com/references/latest/type.html for the parameters that can be passed to each of the resources.

For augeasproviders types (sysctl, sshd) see http://forge.puppetlabs.com/domcleal/augeasproviders.

For limits see http://forge.puppetlabs.com/erwbgy/limits.

Usage

Include the system module in your puppet configuration:

include system

and add required hiera configuration.

Note: To exclude certain system classes when doing 'include system' you can set their schedule parameter to 'never'. This may be useful when testing or debugging issues or just to prevent config lower in the hierarchy being applied.

For example:

system::packages::schedule:  'never'
system::yumgroups::schedule: 'never'

will ignore any configuration for system::packages and system::yumgroups.

augeas

Apply changes to files using the augeas tool. This enables simple configuration file changes to be made without writing new classes.

Example 1:

system::augeas:
  'ntp':
    context: '/files/etc/ntp.conf'
    changes:
      - 'set server[1] 0.uk.pool.ntp.org'
      - 'set server[2] 1.uk.pool.ntp.org'
      - 'set server[3] 2.uk.pool.ntp.org'

Example 2:

system::augeas:
  'test1':
    context: '/files/etc/sysconfig/firstboot'
    changes:
      - 'set RUN_FIRSTBOOT YES'
    onlyif:  'match other_value size > 0'

Example 3:

system::augeas:
  'jboss_conf':
    context: '/files'
    changes:
      - 'set etc/jbossas/jbossas.conf/JBOSS_IP $ipaddress'
      - 'set etc/jbossas/jbossas.conf/JAVA_HOME /usr'
    load_path: '/usr/share/jbossas/lenses'

Defaults:

• ensure: present
• user: root

crontabs

Set user crontab entries

Example configuration:

system::crontabs:
  'root-logrotate':
    command: '/usr/sbin/logrotate'
    user:    'root'
    hour:    '2'
    minute:  '0'

Defaults:

• ensure: present
• user: root

execs

Run idempotent external commands

Example configuration:

system::execs:
  '/bin/mkdir -p /apps/tomcat1/deploy':
    unless:  '/usr/bin/test -d /apps/tomcat1/deploy'
  "/usr/bin/perl -pi -e 's: grep 1.6: egrep \"1.6/1.7\":' /apps/wso2esb1/product/wso2esb/bin/wso2server.sh":
    onlyif: '/bin/grep -w "grep 1.6" /apps/wso2esb1/product/wso2esb/bin/wso2server.sh'

Note: The commands will be run on every Puppet run unless you specify 'onlyif', 'unless' or 'refreshonly' parameters.

facts

Set custom facts using the facter_dot_d Facter plugin that loads facts from /etc/facter/facts.d (https://github.com/ripienaar/facter-facts/tree/master/facts-dot-d)

Example configuration:

system::facts:
  location:
    value: 'London'
  ntpq:
    type:  'script'
    value: "#!/bin/bash\nprintf ntpq=\n/usr/sbin/ntpq -p | /usr/bin/tail -1\n"

These facts can be queried on a host using 'facter -p':

$ facter -p location
London
$ facter -p ntpq
*10.43.4.8       158.43.128.33    2 u  820 1024  377    0.538    0.155   0.048

Set:

system::facts::cleanold: true

to remove facts from the old locations under /etc/profile.d and in /etc/sysconfig/puppet.

files

Create or update files or directories

Example 1 - create a mount point for an NFS mounted directory:

system::files:
  /apps:
    ensure:  'directory'
    owner:   'root'
    group:   'root'
    mode:    '0755'

Example 2 - create a file with the given content:

system::files:
  /etc/motd:
    ensure:  'present'
    owner:   'root'
    group:   'root'
    mode:    '0644'
    content: "Authorised access only\nIf unauthorised log off now or face prosecution\n"

Note: Use double-quotes if your content contains embedded newlines (\n) or tabs (\t). Normally you will also want a terminating newline.

groups

Manage entries in /etc/group

Example configuration:

system::groups:
  'sysadmins':
    ensure: 'present'
    gid:    '1500'
  'ops':
    gid:    '1503'
system::groups::realize:
  - 'keith'

Defaults:

• ensure: present

By default virtual group resources are created that must then be realized. To create real resources instead (as with earlier versions of this module) use:

system::groups::real: 'true'

hosts

Manage entries in /etc/hosts

Example configuration:

system::hosts:
  puppet:
    ensure:       'present'
    ip:           '10.5.11.19'
    host_aliases: [ 'puppet.local' ]

Defaults:

• ensure: present

See: http://docs.puppetlabs.com/references/latest/type.html#host

limits

Manage entries in /etc/security/limits.conf

Example configuration:

system::limits:
  '*':
    nofile:
      soft: 1024
      hard: 2048
  '@weblogic':
    nofile:
      soft: 16384
      hard: 16384
    nproc:
      soft: 2048
      hard: 2048

No defaults.

mail

Manage entries in /etc/aliases or set a relay host

Example configuration:

system::mail:
  aliases:
    postmaster:
      recipient: 'root'
    webmaster:
      recipient: 'fred@domain.com'
  relayhost:     'mail.domain.com'
  type:          'postfix'

No defaults.

See: http://docs.puppetlabs.com/references/latest/type.html#mailalias

Currently only 'postfix' is supported for setting a relay host.

mounts

Manage entries in /etc/fstab

Example configuration:

system::mounts:
  '/home':
    ensure:  'mounted'
    device:  '/dev/mapper/vg_x120-lv_home'
    atboot:  'true'
    fstype:  'ext4'
    options: 'defaults'

Defaults:

• atboot: true
• ensure: mounted

Note: These resources are created last so any required users, groups or mount point directories have a chance to be created first.

network

Configure basic networking: set hostname, enable/disable zeroconf/IPv6, set the default route, configure interfaces and their static routes, configure nameserver resolvers and domains

Example configuration:

system::network::hostname: 'puppet.domain.com'
system::network::gateway:  '10.7.0.1'
system::network::ipv6:     'false'
system::network::zeroconf: 'false'
system::network::dns:
  nameservers: [ '10.7.96.2', '10.7.96.2' ]
  domains:     [ 'domain.com', 'sub.domain.com' ]
system::network::interfaces:
  eth0:
    ipaddress: '10.7.96.21'
    netmask:   '255.255.240.0'
    routes:
      '10.0.0.0/8':
        via: '10.16.0.250'

ntp

Manage NTP servers in /etc/ntp.conf

Example 1:

system::ntp::iburst:  'true'
system::ntp::servers: [ 'ntp1.example.com' ]

Example 2:

system::ntp::iburst:  'true'
system::ntp::country: 'uk'

See https://github.com/erwbgy/puppet-ntp for more details

Note: The NTP algorithm does not work properly with two NTP servers.

packages

Manage system packages

Example configuration:

system::packages:
  AdobeReader_enu:
    ensure: '9.5.1-1'
  ConsoleKit:
    ensure: '0.4.5-2.fc17'

Defaults:

• ensure: installed

schedules

Create schedules that determine when a resource should not be applied and the number times it should be applied within a specified time period.

Example configuration:

system::schedules:
  'maintenance':
    range:  '2 - 4'
    period: 'daily'
    repeat: 1
  'half-hourly':
    period: 'hourly'
    repeat: 2

The defined schedules can then be passed using the 'schedule' parameter to other types.

Example 1:

system::schedule: 'maintenance'

sets the default schedule for all system resources so that they are only run during the maintenance window of 2:00 to 04:59.

Example 2:

system::services::schedule: 'daily'

sets the default schedule for all system::services resources to be once a day.

Example 3:

system::services:
  httpd:
    ensure: 'running'
    enable: 'true'
    schedule: 'half-hourly'

overrides the services schedule for the httpd resource using a custom schedule we defined above.

The default Puppet schedules are:

• daily
• hourly
• monthly
• never
• weekly

and the system::schedule class defines another called always that schedules the resource on every Puppet run.

selbooleans

Manages SELinux booleans

Example configuration:

system::selbooleans:
  'httpd_can_network_connect':
    value: 'on'
    persistent: 'true'

Defaults:

• persistent: false

services

Manage system services

Example configuration:

system::services:
  cups:
    ensure: 'stopped'
    enable: 'false'
  sshd:
    ensure: 'running'
    enable: 'true'
  ntpd:
    ensure: 'running'
    enable: 'true'

Defaults:

• ensure: running

Note:

• Do not specify any services that are managed by other Puppet modules (eg. ntpd or network) otherwise you may get conflicts

sshd

Manage settings in /etc/ssh/sshd.conf

Synchronize host keys file entries across all puppet-managed hosts.

Example configuration:

system::sshd:
  AllowGroups:
    value:     [ 'sshusers', 'admin' ]
  PermitRootLogin:
    value:     'without-password'
    condition: 'Host example.net'

system::sshd::subsystem:
  sftp:
    command: '/usr/libexec/openssh/sftp-server -u 0002'

system::sshd::sync_host_keys: 'true'

No defaults.

See:

• https://github.com/domcleal/augeasproviders/blob/master/lib/puppet/type/sshd_config.rb
• https://github.com/domcleal/augeasproviders/blob/master/lib/puppet/type/sshd_config_subsystem.rb

sysconfig

Manage settings in files under /etc/sysconfig

Example configuration:

system::sysconfig::clock:
  timezone: 'Europe/London'

system::sysconfig::i18n:
  # Run 'locale -a' to see possible lang values
  lang: 'en_GB.utf8'

system::sysconfig::keyboard:
  keytable:     'uk'
  model:        'pc105'
  layout:       'gb'
  keyboardtype: 'pc'

system::sysconfig::puppet:
  server: 'puppet.sbet'

system::sysconfig::selinux:
  state: 'enforcing'

No defaults.

Note: Values must not contain whitespace

sysctl

Manage settings in /etc/sysctl.conf

Example configuration:

system::sysctl:
  kernel.msgmnb:
    value: '131072'
    comment: 'Controls the default maximum size of a message queue'
  kernel.msgmax:
    value: '131072'
    comment: ' Controls the maximum size of a message, in bytes'

No defaults.

See:

• https://github.com/domcleal/augeasproviders/blob/master/lib/puppet/type/sysctl.rb

Note: Quote numeric values to avoid "can't convert Fixnum into String" errors

templates

Create files from ERB templates

Example configuration:

system::templates:
  /etc/motd:
    owner:    'root'
    group:    'root'
    mode:     '0644'
    template: "/var/lib/puppet/templates/motd-%{osfamily}.erb"
  /etc/environment:
    owner:    'root'
    group:    'root'
    mode:     '0644'
    template: "environment.erb"

Default:

• owner: root
• group: root

If template is a relative path then Puppet will look for template file in template_dir (eg. /var/lib/puppet/templates).

Templates can use any facts set for the destination host.

users

Manage users entries in /etc/passwd and /etc/shadow

Example configuration:

system::users:
  'keith':
    ensure:    'present'
    comment:   'Keith Burdis'
    gid:       '500'
    groups:    ['wheel']
    home:      '/home/keith'
    shell:     '/bin/bash'
    uid:       '500'
  'fred':
    comment:   'Fred Bloggs'
    uid:       '503'
    gid:       '503'
    home:      '/home/fred'
    managehome: true
system::users::realize:
  - 'keith'

Defaults:

• ensure: present
• shell: /bin/bash

By default virtual user resources are created that must then be realized. To create real resources instead (as with earlier versions of this module) use:

system::users::real: 'true'

yumgroups

Manage system package groups

Example configuration:

system::yumgroups:
  'Base':
    ensure: 'present'
  'Console internet tools':
    ensure: 'present'
  'Perl Support':
    ensure: 'present'
    usecache: false
  'Ruby Support':
    ensure: 'present'
    optional: true
    usecache: false

Defaults:

• optional: false
• usecache: true
• schedule: daily

Note: Set 'usecache: false' if 'yum -C grouplist' does not work on your system and you are getting System::Yumgroup resources created on every Puppet run

Note: By default the yumgroup type has a 'daily' schedule to reduce the time Puppet runs take - package group changes are usually rare after the host is first set up. This means that it will run once every 24 hours. You override this by supplying your own schedule parameter - see system::schedules to create your own custom schedules.

yumrepos

Manage yum repository files under /etc/yum.repos.d

Example configuration:

system::yumrepos:
  'puppetlabs-deps':
    baseurl:  'http://yum.puppetlabs.com/fedora/f17/dependencies/$basearch'
    descr:    'Puppet Labs Dependencies Fedora 17 - $basearch'
    enabled:  '1'
    gpgcheck: '1'
    gpgkey:   'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-puppetlabs'
  'puppetlabs-products':
    baseurl:  'http://yum.puppetlabs.com/fedora/f17/products/$basearch'
    descr:    'Puppet Labs Products Fedora 17 - $basearch'
    enabled:  '1'
    gpgcheck: '1'
    gpgkey:   'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-puppetlabs'

Defaults:

• enabled: 1
• gpgcheck: 1

providers

The augeasproviders module can be an alternate provider for the host, mailalias and mounttab types.

Example configuration:

system::providers:
  host: 'augeas'
  mailalias: 'augeas'
  mounttab: 'augeas'

Notes

• Do not specify resources that are managed by other Puppet modules otherwise you will get conflict errors.

• As with many default types you can often specify a 'target' parameter to specify a different configuration filename to change.

v0.7.4 (2013-09-22)

• Documentation fixes

• Script to generate hiera network config on an existing host

• Change dependency from ripienaar/concat to puppetlabs/concat (thanks #eshkay)

v0.7.3 (2013-03-19)

• Enable files to be created from ERB templates

• Only apply SELinux boolean changes if SELinux is enabled

• Manage simple mail smart host configuration (initially just Postfix). Mail aliases are now set under 'mail' instead of a separate 'mailaliases'.

• Do not try to set a MAC address on a virtual interface. Instead make virtual interfaces dependent on their parents (#3 thanks eglis).

• Added basic IPv6 support (#2 thanks eglis)

v0.7.2 (2013-02-19)

• Realize groups before users so that user primary groups exist when the user is created.

• Make 'include system' work again (#1 thanks mkm85) by avoiding mandatory parameters in network and adding checks instead.

• Do not restart the network service when config file changes are made as this sometimes causes issues (like the default route going missing). This should be fixed in a later release but for now the network service must be manually restarted.

v0.7.1 (2013-02-13)

• Added ldif2users script to create user/group config from an LDAP export

• Fixed bugs in user and group realize preventing hiera data lookup from working and fixed silly typos in routes.pp

v0.7.0 (2013-02-11)

• By default virtual user and group resources are now created that must then be realized rather than real resources as before. This allows all of the user and group configuration to be added to a common part of the hiera hierarchy but only the relevent users and groups created on each host.

To create real resources instead (and make things work as they did with earlier versions of this module) use:

system::users::real:  'true'
system::groups::real: 'true'

• Added support for basic networking: set hostname, enable/disable zeroconf/IPv6, set the default route, configure interfaces and their static routes, configure nameserver resolvers and domains

• Manage NTP servers in /etc/ntp.conf

v0.6.3 (2013-02-11)

• Added support for managing SELinux booleans

v0.6.2 (Never released)

• Facts that have array values now create multiple facts with the array index as a suffix. For example:

  system::facts:
    software: [ 'jboss', 'httpd' ]
  

creates the facts:

software0: 'jboss'
software1: 'httpd'

v0.6.1 (2013-01-26)

Full Changelog

• Set custom facts using the facter_dot_d Facter plugin that loads facts from /etc/facter/facts.d. Set 'system::facts::cleanold: true' to remove facts from the old locations under /etc/profile.d and in /etc/sysconfig/puppet.

• Facts can now be set by running scripts - see example.yaml.

v0.6.0 (2013-01-25)

• Refactoring to make it easier to use without hiera (ie. just as parameterised classes).

• Added support for schedules so that configuration does not need to be applied with every Puppet run. All classes other than system::providers and system::schedules can be configured with a default schedule, including the system class itself. An 'always' schedule is provided in addition to the default schedules available (eg. hourly, daily, weekly).

• Changed the yumgroup type to have a default 'daily' schedule to reduce the time Puppet runs take - package group changes are usually rare after the host is first set up. Users can override this by supplying their own schedule.

• Documented that particular system classes can be excluded when doing 'include system' by setting their default schedule to 'never' which is useful when testing or debugging issues or just to prevent config lower in the hierarchy from being applied.

• Added support for the augeas type to enable simple configuration file changes to be made without writing new classes

• Use augeas to make sysconfig file changes as it is more reliable. One limitation is that all values are now unquoted so they can't have any whitespace. This only appears to potentially affect system::sysconfig::puppet puppet-extra_opts.

v0.5.3 (2013-01-06)

• Added 'crontabs' to create user crontab entries

• Added 'execs' to run idempotent external commands

v0.5.2 (2012-12-21)

• limits: Fixed examples to show changes due to multiple entry support

• Actually fix the typo in mounts.pp preventing it from working!

• mounts: Updated example to show an NFS share

• example.yaml: Added files examples

• sysctl: Added a note to quote numeric values to avoid "can't convert Fixnum into String" errors

• yumgroups: added a usecache option for when 'yum -C grouplist' does not work

v0.5.1 (2012-12-21)

Full Changelog

• Added 'files' to create directories and populate the content of files. The initial reason was to create mount points for NFS shares.

• Fixed typo in mounts.pp preventing it from working.

• Run 'mounts' in the last stage so that any required users, groups and mount points can be created first.

• Require augeasproviders > 0.5.1 to get bug fix for problems running under 'puppet apply'.

• Require limits > 0.3.1 as this allows more than one entry per user or group.
