chef_user

[edit on GitHub]

Warning

This functionality is available with Chef provisioning and is packaged in the Chef development kit. Chef provisioning is a framework that allows clusters to be managed by the chef-client and the Chef server in the same way nodes are managed: with recipes. Use Chef provisioning to describe, version, deploy, and manage clusters of any size and complexity using a common set of tools.

Use the chef_user resource to manage users.

Syntax

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

chef_user 'value' # see properties section below
  ...
  action :action # see actions section below
end

where

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

Actions

This resource has the following actions:

:create
Default. Use to create a user.
:delete
Use to delete a user.
: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

This resource has the following properties:

admin
Create a client as an admin client. This is required for any user to access Open Source Chef as an administrator.
chef_server
The URL for the Chef server.
complete
Use to specify if this resource defines a user completely. When true, any property not specified by this resource will be reset to default property values.
email
The email address for the user.
external_authentication_uid
ignore_failure

Ruby Types: TrueClass, FalseClass

Continue running a recipe if a resource fails for any reason. Default value: false.

name
The name of the user.
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 very 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
output_key_format
Use to specify the format of a public key. Possible values: pem, der, or openssh. Default value: openssh.
output_key_path
Use to specify the path to the location in which a public key will be written.
raw_json

The user as JSON data. For example:

{
  "name": "Robert Forster"
}
recovery_authentication_enabled
retries

Ruby Type: Integer

The number of times to catch exceptions and retry the resource. Default value: 0.

retry_delay

Ruby Type: Integer

The retry delay (in seconds). Default value: 2.

source_key
Use to copy a public or private key, but apply a different format and password. Use in conjunction with source_key_pass_phrase` and source_key_path.
source_key_pass_phrase
The pass phrase for the public key. Use in conjunction with source_key` and source_key_path.
source_key_path
The path to the public key. Use in conjunction with source_key` and source_key_pass_phrase.
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 very 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

None.
