chef_vault_secret resource

Resources Reference page


Use the chef_vault_secret resource to store secrets in Chef Vault items. Where possible and relevant, this resource attempts to map behavior and functionality to the knife vault sub-commands.

New in Chef Infra Client 16.0.

Syntax


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

chef_vault_secret 'name' do
  admins           String, Array
  clients          String, Array
  data_bag         String
  environment      String
  id               String # default value: 'name' unless specified
  raw_data         Hash, ChefUtils::Mash # default value: {}
  search           String # default value: "*:*"
  action           Symbol # defaults to :create if not specified
end

where:

  • chef_vault_secret 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.
  • admins, clients, data_bag, environment, id, raw_data, and search are the properties available to this resource.

Actions


The chef_vault_secret resource has the following actions:

:create
Create a Chef Vault data bag.
:create_if_missing
Create a Chef Vault data bag unless it already exists.
:delete
Delete a Chef Vault data bag if present.
: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_vault_secret resource has the following properties:

admins
Ruby Type: String, Array | REQUIRED

A list of admin users who should have access to the item. Corresponds to the ‘admin’ option when using the chef-vault knife plugin. Can be specified as a comma separated string or an array.

clients
Ruby Type: String, Array

A search query for the nodes’ API clients that should have access to the item.

data_bag
Ruby Type: String | REQUIRED

The data bag that contains the item.

environment
Ruby Type: String

The Chef environment of the data if storing per environment values.

id
Ruby Type: String | Default Value: The resource block's name

The name of the data bag item if it differs from the name of the resource block

raw_data
Ruby Type: Hash, ChefUtils::Mash | Default Value: {}

The raw data, as a Ruby Hash, that will be stored in the item.

search
Ruby Type: String | Default Value: *:*

Search query that would match the same used for the clients, gets stored as a field in the item.


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 attempts 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 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.

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
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 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

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.

Properties

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 chef_vault_secret resource in recipes:

To create a ‘foo’ item in an existing ‘bar’ data bag:

chef_vault_secret 'foo' do
  data_bag 'bar'
  raw_data({'auth' => 'baz'})
  admins 'jtimberman'
  search '*:*'
end

To allow multiple admins access to an item:

chef_vault_secret 'root-password' do
  admins 'jtimberman,paulmooring'
  data_bag 'secrets'
  raw_data({'auth' => 'DontUseThisPasswordForRoot'})
  search '*:*'
end
