windows_package resource

Resources Reference page


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
  options                     String
  package_name                String, Array
  remote_file_attributes      Hash
  returns                     String, Integer, Array # default value: [0]
  source                      String # default value: "The resource block's name"
  timeout                     String, Integer # default value: 600 (seconds)
  version                     String, Array
  action                      Symbol # defaults to :install if not specified
end

where:

  • windows_package is the resource.
  • name is the name given to the resource block.
  • action identifies which steps Chef Infra Client will take to bring the node into the desired state.
  • checksum, installer_type, options, package_name, remote_file_attributes, returns, source, timeout, and version are the properties available to this resource.

Actions


The windows_package resource has the following actions:

:install
Default. Install a package. If a version is specified, install the specified version of the package.
:nothing
This resource block does not act unless notified by another resource to take action. Once notified, this resource block either runs immediately or is queued up to run at the end of a Chef Infra Client run.
:remove
Remove a package.

Properties


The windows_package resource has the following properties:

checksum
Ruby Type: String

The SHA-256 checksum of the file. Use to prevent a file from being re-downloaded. When the local file matches the checksum, Chef Infra Client does not download it. Use when a URL is specified by the source property.

installer_type
Ruby Type: Symbol

A symbol that specifies the type of package. Possible values: :custom (such as installing a non-.msi file that embeds an .msi-based installer), :inno (Inno Setup), :installshield (InstallShield), :msi (Microsoft Installer Package (MSI)), :nsis (Nullsoft Scriptable Install System (NSIS)), :wise (Wise).

options
Ruby Type: String

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

package_name
Ruby Type: String, Array

An optional property to set the package name if it differs from the resource block’s name.

remote_file_attributes
Ruby Type: Hash

This property allows you to define a hash of properties and their value if the source package to be installed is at a remote location. This hash will be used by the underlying remote_file resource which will fetch the source package.

returns
Ruby Type: String, Integer, Array of integers

Default Value: 0

A comma-delimited list of return codes that indicate the success or failure of the package command that was run.

source
Ruby Type: String | Default Value: The resource block's name

The path to a package in the local file system. The location of the package may be at a URL.

If the source property is not specified, the package name MUST be exactly the same as the display name found in Add/Remove programs or exactly the same as the DisplayName property in the appropriate registry key, which may be one of the following:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall
HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

Note

If there are multiple versions of a package installed with the same display name, all of those packages will be removed unless a version is provided in the version property or unless it can be discovered in the installer file specified by the source property.

timeout
Ruby Type: String, Integer | Default Value: 600

(seconds)

The amount of time (in seconds) to wait before timing out.

version
Ruby Type: String, Array

The version of a package to be installed or upgraded.


Common Resource Functionality


Chef resources include common properties, notifications, and resource guards.

Common Properties

The following properties are common to every resource:

ignore_failure

Ruby Type: true, false | Default Value: false

Continue running a recipe if a resource fails for any reason.

retries

Ruby Type: Integer | Default Value: 0

The number of attempts to catch exceptions and retry the resource.

retry_delay

Ruby Type: Integer | Default Value: 2

The retry delay (in seconds).

sensitive

Ruby Type: true, false | Default Value: false

Ensure that sensitive resource data is not logged by Chef Infra Client.

Notifications

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 notify more than one resource; use a notifies statement for each resource to be notified.

A timer specifies the point during a Chef Infra Client run at which a notification is run. The following timers are available:

:before

Specifies that the action on a notified resource should be run before processing the resource block in which the notification is located.

:delayed

Default. Specifies that a notification should be queued up, and then executed at the end of a Chef Infra 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
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.

Note that subscribes does not apply the specified action to the resource that it listens to - for example:

file '/etc/nginx/ssl/example.crt' do
  mode '0600'
  owner 'root'
end

service 'nginx' do
  subscribes :reload, 'file[/etc/nginx/ssl/example.crt]', :immediately
end

In this case the subscribes property reloads the nginx service whenever its certificate file, located under /etc/nginx/ssl/example.crt, is updated. subscribes does not make any changes to the certificate file itself, it merely listens for a change to the file, and executes the :reload action for its resource (in this example nginx) when a change is detected.

A timer specifies the point during a Chef Infra Client run at which a notification is run. The following timers are available:

:before

Specifies that the action on a notified resource should be run before processing the resource block in which the notification is located.

:delayed

Default. Specifies that a notification should be queued up, and then executed at the end of a Chef Infra 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

Guards

A guard property can be used to evaluate the state of a node during the execution phase of a Chef Infra Client run. Based on the results of this evaluation, a guard property is then used to tell Chef Infra Client if it should continue executing a resource. A guard property accepts either a string value or a Ruby block value:

  • A string is executed as a shell command. If the command returns 0, the guard is applied. If the command returns any other value, then the guard property is not applied. String guards in a powershell_script run Windows PowerShell commands and may return true in addition to 0.
  • A block is executed as Ruby code that must return either true or false. If the block returns true, the guard property is applied. If the block returns false, the guard property is not applied.

A guard property is useful for ensuring that a resource is idempotent by allowing that resource to test for the desired state as it is being executed, and then if the desired state is present, for Chef Infra Client to do nothing.

Properties

The following properties can be used to define a guard that is evaluated during the execution phase of a Chef Infra Client run:

not_if

Prevent a resource from executing when the condition returns true.

only_if

Allow a resource to execute only if the condition returns true.

Examples


The following examples demonstrate various approaches for using the windows_package resource in recipes:

Install a package

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

Specify a URL for the source attribute

windows_package '7zip' do
  source 'http://www.7-zip.org/a/7z938-x64.msi'
end

Specify path and checksum

windows_package '7zip' do
  source 'http://www.7-zip.org/a/7z938-x64.msi'
  checksum '7c8e873991c82ad9cfc123415254ea6101e9a645e12977dcd518979e50fdedf3'
end

Modify remote_file resource attributes

The windows_package resource may specify a package at a remote location using the remote_file_attributes property. This uses the remote_file resource to download the contents at the specified URL and passes in a Hash that modifies the properties of the remote_file resource.

For example:

windows_package '7zip' do
  source 'http://www.7-zip.org/a/7z938-x64.msi'
  remote_file_attributes ({
    :path => 'C:\\7zip.msi',
    :checksum => '7c8e873991c82ad9cfc123415254ea6101e9a645e12977dcd518979e50fdedf3'
  })
end

Download a nsis (Nullsoft) package resource

windows_package 'Mercurial 3.6.1 (64-bit)' do
  source 'http://mercurial.selenic.com/release/windows/Mercurial-3.6.1-x64.exe'
  checksum 'febd29578cb6736163d232708b834a2ddd119aa40abc536b2c313fc5e1b5831d'
end

Download a custom package

windows_package 'Microsoft Visual C++ 2005 Redistributable' do
  source 'https://download.microsoft.com/download/6/B/B/6BB661D6-A8AE-4819-B79F-236472F6070C/vcredist_x86.exe'
  installer_type :custom
  options '/Q'
end
