rhsm_subscription resource¶

[edit on GitHub]

Use the rhsm_subscription resource to add or remove Red Hat Subscription Manager subscriptions from your host. This can be used when a host’s activation_key does not attach all necessary subscriptions to your host.

New in Chef Client 14.0.

Syntax¶

The rhsm_subscription resource has the following syntax:

rhsm_subscription 'name' do
  pool_id      String # default value: 'name' unless specified
  action       Symbol # defaults to :attach if not specified
end

where:

rhsm_subscription 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.
pool_id is the property available to this resource.

Actions¶

:attach: Default. Attach the node to a subscription pool.
:remove: Remove the node from a subscription pool.
: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¶

pool_id

Ruby Type: String

An optional property for specifying the Pool ID if it differs from the resource’s name.

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
