windows_package

windows_package

Use the windows_package resource to manage Microsoft Installer Package (MSI) packages for the Microsoft Windows platform.

Syntax

A windows_package resource block manages a package on a node, typically by installing it. The simplest use of the windows_package resource is:

windows_package 'package_name'

which will install the named package using all of the default options and the default action (:install).

The full syntax for all of the properties that are available to the windows_package resource is:

windows_package 'name' do
  checksum                   String
  installer_type             Symbol
  notifies                   # see description
  options                    String
  provider                   Chef::Provider::Package::Windows
  remote_file_attributes     Hash
  returns                    String, Integer, Array
  source                     String # defaults to 'name' if not specified
  subscribes                 # see description
  timeout                    String, Integer
  action                     Symbol # defaults to :install if not specified
end

where

• windows_package tells the chef-client to manage a package
• 'name' is the name of the package
• :action identifies which steps the chef-client will take to bring the node into the desired state
• checksum, installer_type, options, package_name, provider, remote_file_attributes, returns, source, and timeout are properties of this resource, with the Ruby type shown. See “Properties” section below for more information about all of the properties that may be used with this resource.

Actions

This resource has the following actions:

:install

Default. Install a package. If a version is specified, install the specified version of the package.

:nothing

Define this resource block to do nothing until notified by another resource to take action. When this resource is notified, this resource block is either run immediately or it is queued up to be run at the end of the chef-client run.

:remove

Remove a package.

Properties

This resource has the following properties:

ignore_failure

Ruby Types: TrueClass, FalseClass

Continue running a recipe if a resource fails for any reason. Default value: false.

installer_type

Ruby Type: Symbol

A string that specifies the type of package. Possible values: :msi.

Note

Starting with chef-client version 12, this value is a symbol (:msi) and not a string.

notifies

Ruby Type: Symbol, ‘Chef::Resource[String]’

A resource may notify another resource to take action when its state changes. Specify a 'resource[name]', the :action that resource should take, and then the :timer for that action. A resource may notifiy more than one resource; use a notifies statement for each resource to be notified.

A timer specifies the point during the chef-client run at which a notification is run. The following timers are available:

:delayed

Default. Specifies that a notification should be queued up, and then executed at the very end of the chef-client run.

:immediate, :immediately

Specifies that a notification should be run immediately, per resource notified.

The syntax for notifies is:

notifies :action, 'resource[name]', :timer

options

Ruby Type: String

One (or more) additional options that are passed to the command.

provider

Ruby Type: Chef Class

Optional. Explicitly specifies a provider. See “Providers” section below for more information.

retries

Ruby Type: Integer

The number of times to catch exceptions and retry the resource. Default value: 0.

retry_delay

Ruby Type: Integer

The retry delay (in seconds). Default value: 2.

returns

Ruby Types: String, Integer, Array

A comma-delimited list of return codes that indicate the success or failure of the command that was run remotely. This code signals a successful :install action. Default value: 0.

source

Ruby Type: String

Optional. The path to a package in the local file system. Default value: the name of the resource block See “Syntax” section above for more information.

subscribes

Ruby Type: Symbol, ‘Chef::Resource[String]’

A resource may listen to another resource, and then take action if the state of the resource being listened to changes. Specify a 'resource[name]', the :action to be taken, and then the :timer for that action.

A timer specifies the point during the chef-client run at which a notification is run. The following timers are available:

:delayed

Default. Specifies that a notification should be queued up, and then executed at the very end of the chef-client run.

:immediate, :immediately

Specifies that a notification should be run immediately, per resource notified.

The syntax for subscribes is:

subscribes :action, 'resource[name]', :timer

timeout

Ruby Types: String, Integer

The amount of time (in seconds) to wait before timing out. Default value: 600 (seconds).

Providers

Where a resource represents a piece of the system (and its desired state), a provider defines the steps that are needed to bring that piece of the system from its current state into the desired state.

The chef-client will determine the correct provider based on configuration data collected by Ohai at the start of the chef-client run. This configuration data is then mapped to a platform and an associated list of providers.

Generally, it’s best to let the chef-client choose the provider, and this is (by far) the most common approach. However, in some cases, specifying a provider may be desirable. There are two approaches:

• Use a more specific short name—yum_package "foo" do instead of package "foo" do, script "foo" do instead of bash "foo" do, and so on—when available
• Use the provider property within the resource block to specify the long name of the provider as a property of a resource. For example: provider Chef::Provider::Long::Name

This resource has the following providers:

Chef::Provider::Package, package

When this short name is used, the chef-client will attempt to determine the correct provider during the chef-client run.

Chef::Provider::Package::Windows, windows_package

The provider for the Microsoft Windows platform.

Examples

The following examples demonstrate various approaches for using resources in recipes. If you want to see examples of how Chef uses resources in recipes, take a closer look at the cookbooks that Chef authors and maintains: https://github.com/chef-cookbooks.

Install a package

windows_package '7zip' do
  action :install
  source 'C:\7z920.msi'
end
