Define: sysctl::parameters

This custom resource lets you specify sysctl parameters using a Puppet hash, set as the 'values' parameter.

Parameters

values

A hash that maps kernel parameter names to their desire value.

priority

A numeric value in range 60 - 99. In case of conflict, files with a higher priority override files with a lower priority. Debian reserves 0 - 59 for sysctl settings that are bundled with individual packages. The default is 70. Values in 60 - 69 should be reserved for cluster-wide defaults that should always have a lower priority than role-specific customizations.

If you're not sure, leave this unspecified. The default value of 60 should suit most cases.

Examples

sysctl::parameters { 'swift_performance':
  values   => {
    'net.ipv4.tcp_tw_recycle' => '1',  # disable TIME_WAIT
    'net.ipv4.tcp_tw_reuse'   => '1',
  },
  priority => 90,
}

Parameters:

  • values (Any)
  • ensure (Any) (defaults to: present)
  • priority (Any) (defaults to: 70)
