Where possible we use the upstream ntp templates so that the +results closely match what you'd get if you modified the package default conf +files. + +##Setup + +###What ntp affects + +* ntp package. +* ntp configuration file. +* ntp service. + +###Beginning with ntp + +include '::ntp' is enough to get you up and running. If you wish to pass in +parameters like which servers to use then you can use: + +```puppet +class { '::ntp': + servers => [ 'ntp1.corp.com', 'ntp2.corp.com' ], +} +``` + +##Usage + +All interaction with the ntp module can do be done through the main ntp class. +This means you can simply toggle the options in the ntp class to get at the +full functionality. + +###I just want NTP, what's the minimum I need? + +```puppet +include '::ntp' +``` + +###I just want to tweak the servers, nothing else. + +```puppet +class { '::ntp': + servers => [ 'ntp1.corp.com', 'ntp2.corp.com' ], +} +``` + +###I'd like to make sure I restrict who can connect as well. + +```puppet +class { '::ntp': + servers => [ 'ntp1.corp.com', 'ntp2.corp.com' ], + restrict => 'restrict 127.0.0.1', +} +``` + +###I'd like to opt out of having the service controlled, we use another tool for that. + +```puppet +class { '::ntp': + servers => [ 'ntp1.corp.com', 'ntp2.corp.com' ], + restrict => 'restrict 127.0.0.1', + manage_service => false, +} +``` + +###Looks great! But I'd like a different template, we need to do something unique here. + +```puppet +class { '::ntp': + servers => [ 'ntp1.corp.com', 'ntp2.corp.com' ], + restrict => 'restrict 127.0.0.1', + manage_service => false, + config_template => 'different/module/custom.template.erb', +} +``` + +##Reference + +###Classes + +* ntp: Main class, includes all the rest. +* ntp::install: Handles the packages. +* ntp::config: Handles the configuration file. +* ntp::service: Handles the service. + +###Parameters + +The following parameters are available in the ntp module + +####`autoupdate` + +Deprecated: This parameter previously determined if the ntp module should be +automatically updated to the latest version available. Replaced by package\_ +ensure. + +####`config` + +This sets the file to write ntp configuration into. + +####`config_template` + +This determines which template puppet should use for the ntp configuration. + +####`driftfile` + +This sets the location of the driftfile for ntp. + +####`keys_controlkey` + +Which of the keys is used as the control key. + +####`keys_enable` + +Should the ntp keys functionality be enabled. + +####`keys_file` + +Location of the keys file. + +####`keys_requestkey` + +Which of the keys is used as the request key. + +####`package_ensure` + +This can be set to 'present' or 'latest' or a specific version to choose the +ntp package to be installed. + +####`package_name` + +This determines the name of the package to install. + +####`panic` + +This determines if ntp should 'panic' in the event of a very large clock skew. +We set this to false if you're on a virtual machine by default as they don't +do a great job with keeping time. + +####`preferred_servers` + +List of ntp servers to prefer. Will append prefer for any server in this list +that also appears in the servers list. + +####`restrict` + +This sets the restrict options in the ntp configuration. + +####`servers` + +This selects the servers to use for ntp peers. + +####`service_enable` + +This determines if the service should be enabled at boot. + +####`service_ensure` + +This determines if the service should be running or not. + +####`service_manage` + +This selects if puppet should manage the service in the first place. + +####`service_name` + +This selects the name of the ntp service for puppet to manage. + + +##Limitations + +This module has been built on and tested against Puppet 2.7 and higher. + +The module has been tested on: + +* RedHat Enterprise Linux 5/6 +* Debian 6/7 +* CentOS 5/6 +* Ubuntu 12.04 +* Gentoo +* Arch Linux +* FreeBSD + +Testing on other platforms has been light and cannot be guaranteed. + +##Development + +Puppet Labs modules on the Puppet Forge are open projects, and community +contributions are essential for keeping them great. We can’t access the +huge number of platforms and myriad of hardware, software, and deployment +configurations that Puppet is intended to serve. + +We want to keep it as easy as possible to contribute changes so that our +modules work in your environment. There are a few guidelines that we need +contributors to follow so that we can have a chance of keeping on top of things. + +You can read the complete module contribution guide [on the Puppet Labs wiki.](http://projects.puppetlabs.com/projects/module-site/wiki/Module_contributing) -- cgit v1.2.3
