All Infra resources page

Use the chocolatey_package resource to manage packages using the Chocolatey package manager on the Microsoft Windows platform.

New in Chef Infra Client 12.7.

Syntax

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

chocolatey_package 'name' do
  bulk_query          true, false # default value: false
  list_options        String
  options             String, Array
  package_name        String, Array
  password            String
  returns             Integer, Array # default value: [0, 2]
  source              String
  timeout             String, Integer
  use_choco_list      true, false # default value: false
  user                String
  version             String, Array
  action              Symbol # defaults to :install if not specified
end

where:

• chocolatey_package 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.
• bulk_query, list_options, options, package_name, password, returns, source, timeout, use_choco_list, user, and version are the properties available to this resource.

Actions

The chocolatey_package resource has the following actions:

:install

Install a package. If a version is specified, install the specified version of the package. (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.

:purge

Purge a package. This action typically removes the configuration files as well as the package.

:remove

Remove a package.

:upgrade

Install a package and ensure that a package is the latest version.

Properties

The chocolatey_package resource has the following properties:

bulk_query

Ruby Type: true, false | Default Value: false

Whether to bulk query the Chocolatey server. This makes the provider list all packages instead of doing individual queries.

list_options

Ruby Type: String

One (or more) additional list options that are passed to the command.

New in Chef Infra Client 15.3

options

Ruby Type: String, Array

One (or more) additional options that are passed to the command.

package_name

Ruby Type: String, Array

The name of the package. Default value: the name of the resource block.

password

Ruby Type: String

The password to authenticate to the source.

New in Chef Infra Client 15.3

returns

Ruby Type: Integer, Array | Default Value: [0, 2]

The exit code(s) returned by the choco command that indicate a successful action. See Chocolatey Exit Codes for a complete list of exit codes used by Chocolatey.

New in Chef Client 12.18

source

Ruby Type: String

The optional path to a package on the local file system.

timeout

Ruby Type: String, Integer

The amount of time (in seconds) to wait before timing out.

use_choco_list

Ruby Type: true, false | Default Value: false

Whether to use choco list for getting locally installed packages instead of querying for NuGet package files. This defaults to false since reading the package data is faster.

user

Ruby Type: String

The username to authenticate feeds.

New in Chef Infra Client 15.3

version

Ruby Type: String, Array

The version of a package to be installed or upgraded.

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 chocolatey_package resource in recipes:

Install a Chocolatey package:

chocolatey_package 'name of package' do
  action :install
end

Install a package with options with Chocolatey’s --checksum option:

chocolatey_package 'name of package' do
  options '--checksum 1234567890'
  action :install
end
