windows_feature_dism resource

[edit on GitHub]

Use the windows_feature_dism resource to add, remove, or entirely delete Windows features and roles using DISM.

New in Chef Client 14.0.

Syntax

The windows_feature_dism resource has the following syntax:

windows_feature_dism 'name' do
  all               true, false # default value: false
  feature_name      Array, String # default value: 'name' unless specified
  source            String
  timeout           Integer # default value: 600
  action            Symbol # defaults to :install if not specified
end

where:

  • windows_feature_dism is the resource.
  • name is the name given to the resource block.
  • action identifies which steps the chef-client will take to bring the node into the desired state.
  • all, feature_name, source, and timeout are the properties available to this resource.

Actions

:install
Default. Install a Windows role / feature using DISM.
:remove
Remove a Windows role / feature using DISM.
:delete
Delete a Windows role / feature from the image using DISM.

Properties

all

Ruby Type: True, False | Default Value: false

Install all sub-features. When set to true, this is the equivalent of specifying the /All switch to dism.exe.

feature_name

Ruby Type: Array, String | Default Value: 'name'

The name of the feature(s) or role(s) to install, if it differs from the resource name.

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 the Chef 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 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
source

Ruby Type: String

Specify a local repository for the feature install.

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 the Chef 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 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 Type: Integer | Default Value: 600

Specifies a timeout (in seconds) for the feature installation.
