Description

This module sets up the chrony NTP client/server on the system.

Module development has been based on chrony versions 3.2 - 3.5.

Setup

What chrony affects

  • Installs chrony package(s).
  • Sets up the chrony configuration file from provided data, or using OS default data bundled with module.
  • Sets up the chrony keyfile from provided data.
  • Manages the chrony service.

Setup Requirements

  • Supported OS with chrony package available in a configured package repository.
  • puppetlabs/stdlib module.

Beginning with chrony

To install and configure chrony as a client with OS default settings, simply define the class.

class { 'chrony': }

Usage

Installs and configures chrony as a client with default settings

class { 'chrony': }

Installs and configures chrony with customized source servers

class { 'chrony':
  servers => [
    { hostname => 'ntp1.mydomain.tld' },
    { hostname => 'ntp2.mydomain.tld' }
  ]
}

Installs and configures chrony to serve time to clients on the 192.168.1.0/24 network.

class { 'chrony':
  access_rules => [
    {
      access => 'allow',
      subnet => '192.168.1'
    }
  ]
}

Example using three pool.ntp.org servers as sources, while serving time to the 192.168.0.0/16 network - except for 192.168.2.0/24.

class { 'chrony':
  servers      => [
    {
      hostname => '0.pool.ntp.org',
      iburst   => true,
    },
    {
      hostname => '1.pool.ntp.org',
      iburst   => true,
    },
    {
      hostname => '2.pool.ntp.org',
      iburst   => true,
    },
  ],
  access_rules => [
    {
      access => 'deny',
      subnet => '192.168.2.',
    },
    {
      access => 'allow',
      subnet => '192.168.',
    }
  ],
}

Previous example repeated, but with data provided through hiera.

chrony::servers:
  - hostname: '0.pool.ntp.org'
    iburst:   true
  - hostname: '1.pool.ntp.org'
    iburst:   true
  - hostname: '2.pool.ntp.org'
    iburst:   true
chrony::access_rules:
  - access: 'deny'
    subnet: '192.168.2.'
  - access: 'allow'
    subnet: '192.168.'

include chrony

Example as a client but using a key for authentication

class { 'chrony':
  servers => [
    {
      hostname => 'ntp1.mydomain.tld',
      key      => 5,
    }
  ],
  keys    => [
    {
      id      => 5,
      hashalg => 'SHA1',
      hash    => 'HEX:EC56E6FC27CD0C9B5E6B867DD53F137985279B48',
    }
  ],
}
