windows_workgroup resource¶

Use the windows_workgroup resource to join or change the workgroup of a Windows host.

New in Chef Client 14.5.

Syntax¶

The windows_workgroup resource has the following syntax:

windows_workgroup 'name' do
  password            String
  reboot              Symbol # default value: immediate
  sensitive           true, false # default value: true
  user                String
  workgroup_name      String # default value: 'name' unless specified
  action              Symbol # defaults to :join if not specified
end

where:

windows_workgroup 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.
password, reboot, sensitive, user, and workgroup_name are the properties available to this resource.

Actions¶

The windows_workgroup resource has the following actions:

:join: Update the workgroup.
: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.

Properties¶

The windows_workgroup resource has the following properties:

password

Ruby Type: String

The password for the local administrator user.

reboot

Ruby Type: Symbol | Default Value: immediate

Controls the system reboot behavior post workgroup joining. Reboot immediately, after the Chef run completes, or never. Note that a reboot is necessary for changes to take effect.

sensitive

Ruby Type: true, false | Default Value: true

user

Ruby Type: String

The local administrator user to use to change the workgroup.

workgroup_name

Ruby Type: String | Default Value: 'name'

The name of the workgroup for the computer.

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 times 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 the chef-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 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
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

Guards¶

A guard property can be used to evaluate the state of a node during the execution phase of the chef-client run. Based on the results of this evaluation, a guard property is then used to tell the chef-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 the chef-client to do nothing.

The following properties can be used to define a guard that is evaluated during the execution phase of the chef-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.
