Description

Provides a set of Windows-specific primitives (Chef resources) meant to aid in the creation of cookbooks/recipes targeting the Windows platform.

Requirements

Platform

  • Windows XP
  • Windows Vista
  • Windows Server 2003 R2
  • Windows 7
  • Windows Server 2008 (R1, R2)

Cookbooks

  • chef_handler (windows::reboot_handler leverages the chef_handler LWRP)

Attributes

  • node['windows']['allow_pending_reboots'] - used to configure the WindowsRebootHandler (via the windows::reboot_handler recipe) to act on pending reboots. default is true (ie act on pending reboots). The value of this attribute only has an effect if the windows::reboot_handler is in a node's run list.

Resource/Provider

windows_auto_run

Actions

  • :create: Create an item to be run at login
  • :remove: Remove an item that was previously setup to run at login

Attribute Parameters

  • :name: Name attribute. The name of the value to be stored in the registry
  • :program: The program to be run at login
  • :args: The arguments for the program

Examples

# Run BGInfo at login windows_auto_run 'BGINFO' do program "C:/Sysinternals/bginfo.exe" args "\"C:/Sysinternals/Config.bgi\" /NOLICPROMPT /TIMER:0" not_if { Registry.value_exists?(AUTO_RUN_KEY, 'BGINFO') } action :create end

windows_batch

Execute a batch script using the cmd.exe interpreter (much like the script resources for bash, csh, powershell, perl, python and ruby). A temporary file is created and executed like other script resources, rather than run inline. By their nature, Script resources are not idempotent, as they are completely up to the user's imagination. Use the not_if or only_if meta parameters to guard the resource for idempotence.

Actions

  • :run: run the batch file

Attribute Parameters

  • command: name attribute. Name of the command to execute.
  • code: quoted string of code to execute.
  • creates: a file this command creates - if the file exists, the command will not be run.
  • cwd: current working directory to run the command from.
  • flags: command line flags to pass to the interpreter when invoking.
  • user: A user name or user ID that we should change to before running this command.
  • group: A group name or group ID that we should change to before running this command.

Examples

windows_batch "unzip_and_move_ruby" do
  code <<-EOH
  7z.exe x #{Chef::Config[:file_cache_path]}/ruby-1.8.7-p352-i386-mingw32.7z  -oC:\\source -r -y
  xcopy C:\\source\\ruby-1.8.7-p352-i386-mingw32 C:\\ruby /e /y
  EOH
end

windows_batch "echo some env vars" do
  code <<-EOH
  echo %TEMP%
  echo %SYSTEMDRIVE%
  echo %PATH%
  echo %WINDIR%
  EOH
end

windows_feature

Windows Roles and Features can be thought of as built-in operating system packages that ship with the OS. A server role is a set of software programs that, when they are installed and properly configured, lets a computer perform a specific function for multiple users or other computers within a network. A Role can have multiple Role Services that provide functionality to the Role. Role services are software programs that provide the functionality of a role. Features are software programs that, although they are not directly parts of roles, can support or augment the functionality of one or more roles, or improve the functionality of the server, regardless of which roles are installed. Collectively we refer to all of these attributes as 'features'.

This resource allows you to manage these 'features' in an unattended, idempotent way.

There are two providers for the windows_features which map into Microsoft's two major tools for managing roles/features: Deployment Image Servicing and Management (DISM) and Servermanagercmd (The CLI for Server Manager). As Servermanagercmd is deprecated, Chef will set the default provider to Chef::Provider::WindowsFeature::DISM if DISM is present on the system being configured. The default provider will fall back to Chef::Provider::WindowsFeature::ServerManagerCmd.

For more information on Roles, Role Services and Features see the Microsoft TechNet article on the topic. For a complete list of all features that are available on a node type either of the following commands at a command prompt:

dism /online /Get-Features
servermanagercmd -query

Actions

  • :install: install a Windows role/feature
  • :remove: remove a Windows role/feature

Attribute Parameters

  • feature_name: name of the feature/role to install. The same feature may have different names depending on the provider used (ie DHCPServer vs DHCP; DNS-Server-Full-Role vs DNS).

Providers

  • Chef::Provider::WindowsFeature::DISM: Uses Deployment Image Servicing and Management (DISM) to manage roles/features.
  • Chef::Provider::WindowsFeature::ServerManagerCmd: Uses Server Manager to manage roles/features.

Examples

# enable the node as a DHCP Server
windows_feature "DHCPServer" do
  action :install
end

# enable TFTP
windows_feature "TFTP" do
  action :install
end

# disable Telnet client/server
%w{ TelnetServer TelnetClient }.each do |feature|
  windows_feature feature do
    action :remove
  end
end

#

windows_package

Manage Windows application packages in an unattended, idempotent way.

The following application installers are currently supported:

  • MSI packages
  • InstallShield
  • Wise InstallMaster
  • Inno Setup
  • Nullsoft Scriptable Install System

If the proper installer type is not passed into the resource's installer_type attribute, the provider will do it's best to identify the type by introspecting the installation package. If the installation type cannot be properly identified the :custom value can be passed into the installer_type attribute along with the proper flags for silent/quiet installation (using the options attribute..see example below).

PLEASE NOTE - For proper idempotence the resource's package_name should be the same as the 'DisplayName' registry value in the uninstallation data that is created during package installation. The easiest way to definitively find the proper 'DisplayName' value is to install the package on a machine and search for the uninstall information under the following registry keys:

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall
  • HKEY_LOCAL_MACHINE\Software\Wow6464Node\Microsoft\Windows\CurrentVersion\Uninstall

For maximum flexibility the source attribute supports both remote and local installation packages.

Actions

  • :install: install a package
  • :remove: remove a package. The remove action is completely hit or miss as many application uninstallers do not support a full silent/quiet mode.

Attribute Parameters

  • package_name: name attribute. The 'DisplayName' of the application installation package.
  • source: The source of the windows installer. This can either be a URI or a local path.
  • installer_type: They type of windows installation package. valid values are: :msi, :inno, :nsis, :wise, :installshield, :custom. If this value is not provided, the provider will do it's best to identify the installer type through introspection of the file.
  • checksum: useful if source is remote, the SHA-256 checksum of the file--if the local file matches the checksum, Chef will not download it
  • options: Additional options to pass the underlying installation command

Examples

# install PuTTY (InnoSetup installer)
windows_package "PuTTY version 0.60" do
  source "http://the.earth.li/~sgtatham/putty/latest/x86/putty-0.60-installer.exe"

windows_package "Google Chrome" do
  action :remove
end

# remove 7-Zip
windows_package "7-Zip 9.20 (x64 edition)" do
  action :remove
end

windows_reboot

Sets required data in the node's run_state to notify WindowsRebootHandler a reboot is requested. If Chef run completes successfully a reboot will occur if the WindowsRebootHandler is properly registered as a report handler. As an action of :request will cause a node to reboot every Chef run, this resource is usually notified by other resources...ie restart node after a package is installed (see example below).

Actions

  • :request: requests a reboot at completion of successful Cher run. requires WindowsRebootHandler to be registered as a report handler.
  • :cancel: remove reboot request from node.run_state. this will cancel ALL previously requested reboots as this is a binary state.

Attribute Parameters

  • :timeout: Name attribute. timeout delay in seconds to wait before proceeding with the requested reboot. default is 60 seconds
  • :reason: comment on the reason for the reboot. default is 'Opscode Chef initiated reboot'

Examples

# if the package installs, schedule a reboot at end of chef run
windows_reboot 60 do
  reason 'cause chef said so'
  action :nothing
end
windows_package 'some_package' do
  action :install
  notifies :request, 'windows_reboot[60]'
end

# cancel the previously requested reboot
windows_reboot 60 do
  action :cancel
end

windows_registry

Creates and modifies Windows registry keys.

Actions

  • :create: create a new registry key with the provided values.
  • :modify: modify an existing registry key with the provided values.
  • :force_modify: modify an existing registry key with the provided values. ensures the value is actually set by checking multiple times. useful for fighting race conditions where two processes are trying to set the same registry key. This will be updated in the near future to use 'RegNotifyChangeKeyValue' which is exposed by the WinAPI and allows a process to register for notification on a registry key change.
  • :remove: removes a value from an existing registry key

Attribute Parameters

  • key_name: name attribute. The registry key to create/modify.
  • values: hash of the values to set under the registry key. The individual hash items will become respective 'Value name' => 'Value data' items in the registry key.
  • type: Type of key to create, currently only used for :binary to create REG_BINARY registry keys. Must be a symbol. See Roadmap for future plans.

Examples

# make the local windows proxy match the one set for Chef
proxy = URI.parse(Chef::Config[:http_proxy])
windows_registry 'HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings' do
  values 'ProxyEnable' => 1, 'ProxyServer' => "#{proxy.host}:#{proxy.port}", 'ProxyOverride' => '<local>'
end

# enable Remote Desktop and poke the firewall hole
windows_registry 'HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server' do
  values 'FdenyTSConnections' => 0
end

# Delete an item from the registry
windows_registry 'HKCU\Software\Test' do
  #Key is the name of the value that you want to delete the value is always empty
  values 'ValueToDelete' => ''
  action :remove
end

Library Methods

Registry.value_exists?('HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run','BGINFO')
Registry.key_exists?('HKLM\SOFTWARE\Microsoft')
BgInfo = Registry.get_value('HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run','BGINFO')

windows_path

Actions

  • :add: Add an item to the system path

Attribute Parameters

  • :path: Name attribute. The name of the value to add to the system path

Examples

#Add Sysinternals to the system path
windows_path 'C:\Sysinternals' do
  action :add
end

windows_zipfile

Most version of Windows do not ship with native cli utility for managing compressed files. This resource provides a pure-ruby implementation for managing zip files. Be sure to use the not_if or only_if meta parameters to guard the resource for idempotence or action will be taken on the zip file every Chef run.

Actions

  • :unzip: unzip a compressed file

Attribute Parameters

  • path: name attribute. The path where files will be unzipped to.
  • source: The source of the zip file. This can either be a URI or a local path.
  • overwrite: force an overwrite of the files if the already exists.

Examples

# unzip a remote zip file locally
windows_zipfile "c:/bin" do
  source "http://download.sysinternals.com/Files/SysinternalsSuite.zip"
  action :unzip
  not_if {::File.exists?("c:/bin/PsExec.exe")}
end

# unzip a local zipfile
windows_zipfile "c:/the_codez" do
  source "c:/foo/baz/the_codez.zip"
  action :unzip
end

Exception/Report Handlers

WindowsRebootHandler

Required reboots are a necessary evil of configuring and managing Windows nodes. This report handler (ie fires at the end of successful Chef runs) acts on requested (Chef initiated) or pending (as determined by the OS per configuration action we performed) reboots. The allow_pending_reboots initialization argument should be set to false if you do not want the handler to automatically reboot a node if it has been determined a reboot is pending. Reboots can still be requested explicitly via the windows_reboot LWRP.

Initialization Arguments

  • allow_pending_reboots: indicator on whether the handler should act on a the Window's 'pending reboot' state. default is true
  • timeout: timeout delay in seconds to wait before proceeding with the reboot. default is 60 seconds
  • reason: comment on the reason for the reboot. default is 'Opscode Chef initiated reboot'

Usage

Just place an explicit dependency on this cookbook (using depends in the cookbook's metadata.rb) from any cookbook where you would like to use the Windows-specific resources/providers that ship with this cookbook.

default

Convenience recipe that installs supporting gems for many of the resources/providers that ship with this cookbook.

reboot_handler

Leverages the chef_handler LWRP to register the WindowsRebootHandler report handler that ships as part of this cookbook. By default this handler is set to automatically act on pending reboots. If you would like to change this behavior override node['windows']['allow_pending_reboots'] and set the value to false. For example:

% cat roles/base.rb
name "base"
description "base role"
override_attributes(
  "windows" => {
    "allow_pending_reboots" => false
  }
)

This will still allow a reboot to be explicitly requested via the windows_reboot LWRP.
