Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Description

This cookbook is used to configure system limits.conf as well as limits.d configuration files through LWRP.

Requirements

Platform

  • Debian
  • Ubuntu
  • CentOS
  • Red Hat
  • Fedora
  • should work on most linux platforms, just not explicity tested

Attributes

See attributes/default.rb for default values.

  • node['limits']['system_conf'] - Location of limits.conf on system (defaults to /etc/security/limits.conf)
  • node['limits']['system_limits'] - Array of limits (default empty array)
  • node['limits']['conf_dir'] - Directory of limits.d (defaults to /etc/security/limit.d)

Recipes

default

Include the default recipe in a run list in order to configure the system limits.conf. Attribute node['limits']['system_limits'] will be used.

Resources/Providers

limits_config

This cookbook contains the limits_config LWRP. This LWRP will use node['limits']['conf_dir'] to lay down a limits.d configuration file.

Actions

  • :create: creates limits.d config file
  • :delete: removes limits.d config file

Attribute Parameters

  • name: will be used as the conf file name (limits.d/#{name}.conf)
  • limits: array of limits (See example below for format)
  • system: true or false, ignores name attribute in favor of node['limits']['system_conf'] path

Examples

tomcat_limits = [{ 'domain' => 'tomcat',
                    'type'   => '-',
                    'item' => 'nofile',
                    'value' => '4096' }]

# creates /etc/security/limits.d/tomcat.conf
limits_config 'tomcat' do
  limits tomcat_limits
  action :create
end

# creates /etc/security/limits.conf
limits_config 'configure system limits.conf' do
  limits tomcat_limits
  system true
  action :create
end 

Usage

Simply add dependency to gain access to limits_config LWRP (examples above). In order to configure /etc/security/limits.conf, set node['limits']['system_limits'] and include_recipe 'limits::default'.
