chef_acl Resource

Edit this page in the Chef repository

Resources Reference page

Use the chef_acl resource to interact with access control lists (ACLs) that exist on the Chef Infra Server.

Syntax

The syntax for using the chef_acl resource in a recipe is as follows:

chef_acl 'name' do
  attribute 'value' # see properties section below
  ...
  action :action # see actions section below
end

where:

• chef_acl tells Chef Infra Client to use the Chef::Provider::ChefAcl provider during a Chef Infra Client run
• name is the name of the resource block; when the path property is not specified as part of a recipe, name is also the name of the Chef Infra Client.
• attribute is zero (or more) of the properties that are available for this resource
• action identifies which steps Chef Infra Client will take to bring the node into the desired state

Actions

The chef_acl resource has the following actions:

:create

Default.

: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.

Properties

The chef_acl resource has the following properties:

chef_server

The URL for the Chef Infra Server.

complete

Use to specify if this resource defines a chef-client completely. When true, any property not specified by this resource will be reset to default property values.

ignore_failure

Ruby Type: true, false | Default Value: false

Continue running a recipe if a resource fails for any reason.

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, per resource notified.

The syntax for notifies is:

notifies :action, 'resource[name]', :timer

path

A path to a directory in the chef-repo against which the ACL is applied. For example: nodes, nodes/*, nodes/my_node, */*, **, roles/base, data/secrets, cookbooks/apache2, /users/*, and so on.

raw_json

Chef Infra Client as JSON data. For example:

{
  "clientname": "client_name",
  "orgname": "org_name",
  "validator": false,
  "certificate": "-----BEGIN CERTIFICATE-----\n
                  ...
                  1234567890abcdefghijklmnopq\n
                  ...
                  -----END CERTIFICATE-----\n",
  "name": "node_name"
}

recursive

Use to apply changes to child objects. Use :on_change to apply changes to child objects only if the parent object changes. Set to true to apply changes even if the parent object does not change. Set to false to prevent any changes. Default value: :on_change.

remove_rights

Use to remove rights. For example:

remove_rights :read, :users => 'jkeiser', :groups => [ 'admins', 'users' ]

or:

remove_rights [ :create, :read ], :users => [ 'jkeiser', 'adam' ]

or:

remove_rights :all, :users => [ 'jkeiser', 'adam' ]

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 retry delay (in seconds).

rights

Use to add rights. Syntax: :right, :right => 'user', :groups => [ 'group', 'group']. For example:

rights :read, :users => 'jkeiser', :groups => [ 'admins', 'users' ]

or:

rights [ :create, :read ], :users => [ 'jkeiser', 'adam' ]

or:

rights :all, :users => 'jkeiser'

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, per resource notified.

The syntax for subscribes is:

subscribes :action, 'resource[name]', :timer
