zypper_repository Resource

Edit this page in the Chef repository

All Infra resources page

Use the zypper_repository resource to create Zypper package repositories on SUSE Enterprise Linux and openSUSE systems. This resource maintains full compatibility with the zypper_repository resource in the existing zypper cookbook.

New in Chef Infra Client 13.3.

Syntax

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

zypper_repository 'name' do
  autorefresh            true, false # default value: true
  baseurl                String
  cookbook               String # default value: "The cookbook containing the resource"
  description            String
  enabled                true, false # default value: true
  gpgautoimportkeys      true, false # default value: true
  gpgcheck               true, false # default value: true
  gpgkey                 String, Array # default value: []
  keeppackages           true, false # default value: false
  mirrorlist             String
  mode                   String, Integer # default value: "0644"
  path                   String
  priority               Integer # default value: 99
  refresh_cache          true, false # default value: true
  repo_name              String # default value: 'name' unless specified
  source                 String
  type                   String # default value: "NONE"
  action                 Symbol # defaults to :create if not specified
end

where:

• zypper_repository 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.
• autorefresh, baseurl, cookbook, description, enabled, gpgautoimportkeys, gpgcheck, gpgkey, keeppackages, mirrorlist, mode, path, priority, refresh_cache, repo_name, source, and type are the properties available to this resource.

Actions

The zypper_repository resource has the following actions:

:create

Add a new Zypper repository. (default)

:nothing

This resource block doesn’t 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.

:refresh

Refresh Zypper repository.

:remove

Remove a Zypper repository.

repo_name

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

An optional property to set the repository name if it differs from the resource block’s name.

Ruby Type: String

The name of the template for the repository file. Only necessary if you’re using a custom template for the repository file.

type

Ruby Type: String | Default Value: NONE

Specifies the repository type.

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 won’t 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 isn’t 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 doesn’t exist, an error is raised. In contrast, subscribes won’t fail if the source resource isn’t 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 doesn’t 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 doesn’t 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 doesn’t exist, the subscription won’t raise an error. Contrast this with the stricter semantics of notifies, which will raise an error if the other resource doesn’t 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 isn’t 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 isn’t 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’s being executed, and then if the desired state is present, for Chef Infra Client to don’thing.

The following properties can be used to define a guard that’s 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 zypper_repository resource in recipes:

Add the Apache repo on openSUSE Leap 15:

zypper_repository 'apache' do
  baseurl 'http://download.opensuse.org/repositories/Apache'
  path '/openSUSE_Leap_15.2'
  type 'rpm-md'
  priority '100'
end

Remove the repo named ‘apache’:

zypper_repository 'apache' do
  action :delete
end

Refresh the repo named ‘apache’:

zypper_repository 'apache' do
  action :refresh
end
