chef_handler Cookbook

Build Status Cookbook Version

Creates a configured handler path for distributing Chef report and exception handlers. Also exposes an LWRP for enabling Chef handlers from within recipe code (as opposed to hard coding in the client.rb file).

Requirements

Platforms

  • Debian/Ubuntu
  • RHEL/CentOS/Scientific/Amazon/Oracle
  • Windows

Chef

  • Chef 12.1+

Cookbooks

  • none

Attributes

node['chef_handler']['handler_path'] - location to drop off handlers directory, default is a folder named 'handlers' in Chef's file cache directory

Custom Resources

chef_handler

Requires, configures and enables handlers on the node for the current Chef run. Also has the ability to pass arguments to the handlers initializer. This allows initialization data to be pulled from a node's attribute data.

It is best to declare chef_handler resources early on in the compile phase so they are available to fire for any exceptions during the Chef run. If you have a base role you would want any recipes that register Chef handlers to come first in the run_list.

Actions

  • :enable: Enables the Chef handler for the current Chef run on the current node
  • :disable: Disables the Chef handler for the current Chef run on the current node

Attribute Parameters

  • class_name: name attribute. The name of the handler class (can be module name-spaced).
  • source: full path to the handler file. can also be a gem path if the handler ships as part of a Ruby gem. can also be nil, in which case the file must be loaded as a library.
  • arguments: an array of arguments to pass the handler's class initializer
  • supports: type of Chef Handler to register as, i.e. :report, :exception or both. default is :report => true, :exception => true

Example

    # register the Chef::Handler::JsonFile handler
    # that ships with the Chef gem
    chef_handler "Chef::Handler::JsonFile" do
      source "chef/handler/json_file"
      arguments :path => '/var/chef/reports'
      action :enable
    end

    # do the same but during the compile phase
    chef_handler "Chef::Handler::JsonFile" do
      source "chef/handler/json_file"
      arguments :path => '/var/chef/reports'
      action :nothing
    end.run_action(:enable)

    # handle exceptions only
    chef_handler "Chef::Handler::JsonFile" do
      source "chef/handler/json_file"
      arguments :path => '/var/chef/reports'
      supports :exception => true
      action :enable
    end

    # enable the MyCorp::MyLibraryHandler handler which was dropped off in a
    # standard chef library file.
    chef_handler "MyCorp::MyLibraryHandler" do
      action :enable
    end

Usage

default

Put the recipe chef_handler at the start of the node's run list to make sure that custom handlers are dropped off early on in the Chef run and available for later recipes.

For information on how to write report and exception handlers for Chef, please see the Chef wiki pages: https://docs.chef.io/handlers.html

json_file

Leverages the chef_handler LWRP to automatically register the Chef::Handler::JsonFile handler that ships as part of Chef. This handler serializes the run status data to a JSON file located at /var/chef/reports.

Unit Testing

chef_handler provides built in chefspec matchers for assisting unit tests. These matchers will only be loaded if chefspec is already loaded. Following is an example of asserting against the jsonfile handler:

  expect(runner).to enable_chef_handler("Chef::Handler::JsonFile").with(
    source: "chef/handler/json_file",
    arguments: { :path => '/var/chef/reports'},
    supports: {:exception => true}
    )
  end

chef_handler cookbook CHANGELOG

This file is used to list changes made in each version of the chef_handler cookbook.

2.1.2 (2017-06-19)

  • Use a SPDX standard license string
  • Remove CloudkickHandler references from the readme
  • Use default_action in the resource to resolve FC074
  • Reduce handler location log level to debug

2.1.1 (2017-04-11)

  • Fixed Chef 13 compatibility
  • Add supported OS list to metadata

2.1.0 (2016-12-27)

  • Support Chefspec 4.1+ matchers only
  • Yank out converge_by to avoid bogus resource updates

2.0.0 (2016-09-16)

  • Testing updates
  • Require Chef 12.1

v1.4.0 (2016-05-13)

  • Allow defining handlers in a cookbook libraries and then enabling them with the chef_handler resource without actually providing a file as a source. This simplifies the delivery of the handler file itself. See the readme for an example.

v1.3.0 (2016-02-16)

  • Added state attributes to the custom resource
  • Added source_url and issues_url to metadata.rb
  • Replaced attributes for root user and group with the Ohai defined values to simplify the logic of the cookbook
  • Added lint, unit, and itegration testing in Travis CI
  • Added Test Kitchen testing of the recipes and the custom resource via a test cookbook
  • Added Berksfile
  • Added chefignore and .gitignore files
  • Added .rubocop.yml config and resolve multiple issues
  • Updated contributing and testing docs to the latest
  • Added all testing dependencies to the Gemfile
  • Added maintainers.md and maintainers.toml files
  • Expanded the Rakefile for simplified testing

v1.2.0 (2015-06-25)

  • Move to support Chef 12+ only. Removes old 'handler class reload' behavior - it isn't necessary because chef-client forks and doesn't share a process between runs.

v1.1.9 (2015-05-26)

  • Bugfixes from 1.1.8 - loading without source is not allowed again. Class unloading is performed more carefully. Tests for resource providers.

v1.1.8 (2015-05-14)

  • Updated Contribution and Readme docs
  • Fix ChefSpec matchers
  • Allow handler to load classes when no source is provided.

v1.1.6 (2014-04-09)

  • [COOK-4494] - Add ChefSpec matchers

v1.1.5 (2014-02-25)

  • [COOK-4117] - use the correct scope when searching the children class name

v1.1.4

  • [COOK-2146] - style updates

v1.1.2

  • [COOK-1989] - fix scope for handler local variable to the enable block

v1.1.0

  • [COOK-1645] - properly delete old handlers
  • [COOK-1322] - support platforms that use 'wheel' as root group'

v1.0.8

  • [COOK-1177] - doesn't work on windows due to use of unix specific attributes

v1.0.6

  • [COOK-1069] - typo in chef_handler readme

v1.0.4

  • [COOK-654] dont try and access a class before it has been loaded
  • fix bad boolean check (if vs unless)

v1.0.2

  • [COOK-620] ensure handler code is reloaded during daemonized chef runs
