Requirements

Overview

This modules allows to configure sysctl.

Usage

node "mynode" inherits ... {
  sysctl::value { "vm.nr_hugepages": value => "1583"}
}

When setting a key that contains multiple values, use a tab to separate the values:

node "mynode" inherits ... {
  sysctl::value { 'net.ipv4.tcp_rmem':
      value => "4096\t131072\t131072",
  }
}

If another config file then /etc/sysctl.conf (default) is required, use target for this:

node "mynode" inherits ... {
  sysctl::value { 'net.ipv4.tcp_rmem':
      value => "4096\t131072\t131072",
      target => '/etc/sysctl.d/mysysctl.conf',
  }
}

To avoid duplication the sysctl::value calls multiple settings can be managed like this:

$my_sysctl_settings = {
  "net.ipv4.ip_forward"          => { value => 1 },
  "net.ipv6.conf.all.forwarding" => { value => 1 },
}

# Specify defaults for all the sysctl::value to be created (
$my_sysctl_defaults = {
  require => Package['aa']
}

create_resources(sysctl::value,$my_sysctl_settings,$my_sysctl_defaults)
