openssl_x509_request resource¶

[edit on GitHub]

Use the openssl_x509_request resource to generate PEM-formatted x509 certificates requests. If no existing key is specified, the resource will automatically generate a passwordless key with the certificate.

New in Chef Client 14.4.

Syntax¶

The openssl_x509_request resource has the following syntax:

openssl_x509_request 'name' do
  city             String
  common_name      String
  country          String
  email            String
  group            String
  key_curve        String # default value: prime256v1
  key_file         String
  key_length       Integer # default value: 2048
  key_pass         String
  key_type         String # default value: ec
  mode             Integer, String
  org              String
  org_unit         String
  owner            String
  path             String # default value: 'name' unless specified
  state            String
  action           Symbol # defaults to :create if not specified
end

where:

openssl_x509_request 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.
city, common_name, country, email, group, key_curve, key_file, key_length, key_pass, key_type, mode, org, org_unit, owner, path, and state are the properties available to this resource.

Actions¶

The openssl_x509_request resource has the following actions:

:create: Default. Create the certificate request file.
: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¶

city

Ruby Type: String

Value for the L certificate field.

common_name

Ruby Type: String

Value for the CN certificate field.

country

Ruby Type: String

Value for the C certificate field.

email

Ruby Type: String

Value for the email certificate field.

group

Ruby Type: String

The group ownership applied to all files created by the resource.

key_curve

Ruby Type: String | Default Value: prime256v1

The desired curve of the generated key (if key_type is equal to ‘ec’). Run openssl ecparam -list_curves to see available options.

key_file

Ruby Type: String

The path to a certificate key file on the filesystem. If the key_file property is specified, the resource will attempt to source a key from this location. If no key file is found, the resource will generate a new key file at this location. If the key_file property is not specified, the resource will generate a key file in the same directory as the generated certificate, with the same name as the generated certificate.

key_length

Ruby Type: Integer | Default Value: 2048

The desired bit length of the generated key (if key_type is equal to ‘rsa’). Available options are 1024, 2048, 4096, and 8192.

key_pass

Ruby Type: String

The passphrase for an existing key’s passphrase.

key_type

Ruby Type: String | Default Value: ec

The desired type of the generated key (rsa or ec).

mode

Ruby Type: Integer, String

The permission mode applied to all files created by the resource.

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 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 notifies is:

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

org

Ruby Type: String

Value for the O certificate field.

org_unit

Ruby Type: String

Value for the OU certificate field.

owner

Ruby Type: String

The owner applied to all files created by the resource.

path

Ruby Type: String

The path to write the file to, if it differs from the resource name.

state

Ruby Type: String

Value for the ST certificate field.

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

Examples¶

Create a certificate request file

openssl_x509_request '/etc/ssl_test/my_ec_request.csr' do
  common_name 'myecrequest.example.com'
  org 'Test Kitchen Example'
  org_unit 'Kitchens'
  country 'UK'
end
