Notifications🎯

notifies

Ruby Type: Symbol, 'Chef::Resource[String]'

When one resource's state changes, it may alert another resource to take appropriate action. Name the resource, specify the activity it should perform, and then set a timer for that action. When notifying multiple resources, use a notifies statement for each resource that needs to be informed.

An error is triggered if the referenced resource is missing. In contrast, if the source resource cannot be located, it will not fail.

When a notification is run during a Chef Infra Client run is determined by a timer. There are the upcoming timings available:

• : before
  Specifies that the action on a resource that has received a notification should be executed before processing the resource block that contains the notification.

• : delayed
  Default. Specifies that execution of notification should be queued up for execution after a run of the Chef Infra Client.

• :immediate, :immediately
  Specifies that for each resource informed, a notification should be run right away.

Guards💯

During the execution stage of a Chef Infra Client run, the condition of a node can be assessed using a guard property. A guard property is then used to inform Chef Infra Client whether it should keep running a resource in response to the findings of this assessment. Both a Ruby block value and a string value are acceptable values for a guard property:

• A string is used to run a command in the shell. The guard is applied if the command returns 0. The guard property is not used if the command returns any other value. In a PowerShell script, string guards can return true in addition to 0 and launch Windows PowerShell commands.
   
• The Ruby code that executes a block must return either true or false. The guard property is used if the block returns true. The guard attribute is not used if the block returns false.
   

By allowing a chef resource to check for the desired state as it is being performed and then do nothing if the required state is present, a guard property helps guarantee that a resource is idempotent.

Properties

Every chef resources shares the following characteristics: A guard may be defined using the chef resources following properties to be assessed during the execution phase of a Chef Infra Client run:

• not_if
  When the condition returns true, don't let a resource run.
   
• only_if
  Only permit the use of a resource if the condition returns true.
