All Infra resources page

Use the powershell_package_source resource to register a PowerShell package source and a Powershell package provider. There are two distinct objects we care about here. The first is a package source like a PowerShell repository or a NuGet Source. The second object is a provider that PowerShell uses to get to that source with, like PowerShellGet, NuGet, Chocolatey, etc.

New in Chef Infra Client 14.3.

Syntax

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

powershell_package_source 'name' do
  new_name                     String
  password                     String
  provider_name                String # default value: "NuGet"
  publish_location             String
  script_publish_location      String
  script_source_location       String
  source_location              String
  source_name                  String # default value: 'name' unless specified
  trusted                      true, false # default value: false
  user                         String
  action                       Symbol # defaults to :register if not specified
end

where:

powershell_package_source 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.
new_name, password, provider_name, publish_location, script_publish_location, script_source_location, source_location, source_name, trusted, and user are the properties available to this resource.

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.

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 powershell_package_source resource in recipes:

Add a new PowerShell repository that is not trusted and which requires credentials to connect to:

powershell_package_source 'PowerShellModules' do
  source_name                  "PowerShellModules"
  source_location              "https://pkgs.dev.azure.com/some-org/some-project/_packaging/some_feed/nuget/v2"
  publish_location             "https://pkgs.dev.azure.com/some-org/some-project/_packaging/some_feed/nuget/v2"
  trusted                      false
  user                         "someuser@somelocation.io"
  password                     "my_password"
  provider_name                "PSRepository"
  action                       :register
end

Add a new package source that uses Chocolatey as the package provider:

powershell_package_source 'PowerShellModules' do
  source_name                  "PowerShellModules"
  source_location              "https://pkgs.dev.azure.com/some-org/some-project/_packaging/some_feed/nuget/v2"
  publish_location             "https://pkgs.dev.azure.com/some-org/some-project/_packaging/some_feed/nuget/v2"
  trusted                      true
  provider_name                "chocolatey"
  action                       :register
end

Add a new PowerShell script source that is trusted:

powershell_package_source 'MyDodgyScript' do
  source_name                  "MyDodgyScript"
  script_source_location       "https://pkgs.dev.azure.com/some-org/some-project/_packaging/some_feed/nuget/v2"
  script_publish_location      "https://pkgs.dev.azure.com/some-org/some-project/_packaging/some_feed/nuget/v2"
  trusted                      true
  action                       :register
end

Update an existing PowerShell repository to make it trusted:

powershell_package_source 'MyPSModule' do
  source_name                  "MyPSModule"
  trusted                      true
  action                       :set
end

Update a Nuget package source with a new name and make it trusted:

powershell_package_source 'PowerShellModules -> GoldFishBowl' do
  source_name                  "PowerShellModules"
  new_name                     "GoldFishBowl"
  provider_name                "Nuget"
  trusted                      true
  action                       :set
end

Update a Nuget package source with a new name when the source is secured with a username and password:

powershell_package_source 'PowerShellModules -> GoldFishBowl' do
  source_name                  "PowerShellModules"
  new_name                     "GoldFishBowl"
  trusted                      true
  user                         "user@domain.io"
  password                     "some_secret_password"
  action                       :set
end

Unregister a package source:

powershell_package_source 'PowerShellModules' do
  source_name                  "PowerShellModules"
  action                       :unregister
end
