chrony_conf resource

[edit on GitHub]

Use the chrony_conf Chef InSpec audit resource to test the synchronization settings defined in the chrony.conf file. This file is typically located at /etc/chrony.conf.

Availability

Installation

This resource is distributed along with Chef InSpec itself. You can use it automatically.

Syntax

An chrony_conf resource block declares the synchronization settings that should be tested:

describe chrony_conf('PATH') do
  its('setting_name') { should eq 'VALUE' }
end

where:

  • 'setting_name' is a synchronization setting defined in the chrony.conf file.
  • ('path') is the non-default path to the chrony.conf file (default path is /etc/chrony.conf).
  • { should eq 'value' } is the value that is expected.

Examples

The following examples show how to use this Chef InSpec audit resource.

This resource matches any service listed in the chrony.conf file.

Test for clock drift against named servers

describe chrony_conf do
  its('driftfile') { should cmp '/var/lib/chrony/drift' }
  its('server') do
    should cmp [
      '0.ubuntu.pool.ntp.org',
      '1.ubuntu.pool.ntp.org',
      '2.ubuntu.pool.ntp.org'
      ]
    end
end

Test that an NTP server exists and a specific subnet is specified from which NTP clients are accessible

describe chrony_conf do
  its('server') { should_not eq nil }
  its('allow') { should include '192.168.0.0/16'}
end
