All Infra resources page

Use the rhsm_register resource to register a node with the Red Hat Subscription Manager or a local Red Hat Satellite server.

New in Chef Infra Client 14.0.

Syntax

The full syntax for all of the properties that are available to the rhsm_register resource is:

rhsm_register 'name' do
  activation_key             String, Array
  auto_attach                true, false # default value: false
  base_url                   String
  environment                String
  force                      true, false # default value: false
  https_for_ca_consumer      true, false # default value: false
  install_katello_agent      true, false # default value: true
  organization               String
  password                   String
  release                    Float, String
  satellite_host             String
  server_url                 String
  service_level              String
  system_name                String
  username                   String
  action                     Symbol # defaults to :register if not specified
end

where:

• rhsm_register 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.
• activation_key, auto_attach, base_url, environment, force, https_for_ca_consumer, install_katello_agent, organization, password, release, satellite_host, server_url, service_level, system_name, and username are the properties available to this resource.

Actions

The rhsm_register resource has the following actions:

: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.

:register

Register the node with RHSM. (default)

:unregister

Unregister the node from RHSM.

Properties

The rhsm_register resource has the following properties:

activation_key

Ruby Type: String, Array

A string or array of activation keys to use when registering; you must also specify the ‘organization’ property when using this property.

auto_attach

Ruby Type: true, false | Default Value: false

If true, RHSM will attempt to automatically attach the host to applicable subscriptions. It is generally better to use an activation key with the subscriptions pre-defined.

base_url

Ruby Type: String

The hostname of the content delivery server to use to receive updates. Both Customer Portal Subscription Management and Subscription Asset Manager use Red Hat’s hosted content delivery services, with the URL https://cdn.redhat.com. Since Satellite 6 hosts its own content, the URL must be used for systems registered with Satellite 6.

New in Chef Infra Client 17.8

environment

Ruby Type: String

The environment to use when registering; required when using the username and password properties.

force

Ruby Type: true, false | Default Value: false

If true, the system will be registered even if it is already registered. Normally, any register operations will fail if the machine has already been registered.

https_for_ca_consumer

Ruby Type: true, false | Default Value: false

If true, Chef Infra Client will fetch the katello-ca-consumer-latest.noarch.rpm from the satellite_host using HTTPS.

New in Chef Infra Client 15.9

install_katello_agent

Ruby Type: true, false | Default Value: true

If true, the ‘katello-agent’ RPM will be installed.

organization

Ruby Type: String

The organization to use when registering; required when using the ‘activation_key’ property.

password

Ruby Type: String

The password to use when registering. This property is not applicable if using an activation key. If specified, username and environment are also required.

release

Ruby Type: Float, String

Sets the operating system minor release to use for subscriptions for the system. Products and updates are limited to the specified minor release version. This is used with the auto_attach or activation_key options. For example, release '6.4' will append --release=6.4 to the register command.

New in Chef Infra Client 17.8

satellite_host

Ruby Type: String

The FQDN of the Satellite host to register with. If this property is not specified, the host will register with Red Hat’s public RHSM service.

server_url

Ruby Type: String

The hostname of the subscription service to use. The default is Customer Portal Subscription Management, subscription.rhn.redhat.com. If you do not use this option, the system registers with Customer Portal Subscription Management.

New in Chef Infra Client 17.8

service_level

Ruby Type: String

Sets the service level to use for subscriptions on the registering machine. This is only used with the auto_attach option.

New in Chef Infra Client 17.8

system_name

Ruby Type: String

The name of the system to register, defaults to the hostname.

New in Chef Infra Client 16.5

username

Ruby Type: String

The username to use when registering. This property is not applicable if using an activation key. If specified, password and environment properties are also required.

Common Resource Functionality

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

Common Properties

The following properties are common to every resource:

compile_time

Ruby Type: true, false | Default Value: false

Control the phase during which the resource is run on the node. Set to true to run while the resource collection is being built (the compile phase). Set to false to run while Chef Infra Client is configuring the node (the converge phase).

ignore_failure

Ruby Type: true, false, :quiet | Default Value: false

Continue running a recipe if a resource fails for any reason. :quiet will not display the full stack trace and the recipe will continue to run if a resource fails.

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 delay in seconds between retry attempts.

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.

If the referenced resource does not exist, an error is raised. In contrast, subscribes will not fail if the source resource is not found.

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, for each 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.

If the other resource does not exist, the subscription will not raise an error. Contrast this with the stricter semantics of notifies, which will raise an error if the other resource does not exist.

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, for each 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.

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 rhsm_register resource in recipes:

Register a node with RHSM

rhsm_register 'my-host' do
  activation_key 'ABCD1234'
  organization 'my_org'
end
