dmg_package resource¶

[edit on GitHub]

Use the dmg_package resource to install a package from a .dmg file. The resource will retrieve the file from a remote URL, mount it using OS X’s hdidutil, copy the application to the specified destination (/Applications), and detach the image using hdiutil. The .dmg file will be stored in the Chef::Config[:file_cache_path].

New in Chef Client 14.0.

Syntax¶

This resource has the following syntax:

dmg_package 'name' do
  accept_eula                true, false # default value: 'false'
  allow_untrusted            true, false # default value: 'false'
  app                        String # default value: 'name'
  checksum                   String
  destination                String # default value: '/Applications'
  dmg_name                   String
  dmg_passphrase             String
  file                       String
  headers                    Hash, nil # default value: 'nil'
  notifies                   # see description
  owner                      String
  package_id                 String
  source                     String
  subscribes                 # see description
  type                       String # default value: 'app'
  volumes_dir                String
  action                     Symbol # defaults to :install if not specified
end

where:

dmg_package 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.
accept_eula, allow_untrusted, app, checksum, destination, dmg_name, dmg_passphrase, file, headers, notifies, owner, package_id, source, subscribes, type, and volumes_dir are the properties available to this resource

Actions¶

The dmg_package resource has the following actions:

:install: Default. Installs the application.
: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¶

The dmg_package resource has the following properties:

accept_eula

Ruby Type: true, false | Default Value: false

Specify if the application’s EULA should be accepted, if applicable.

allow_untrusted

Ruby Type: true, false | Default Value: false

Allow installation of packages that do not have trusted certificates.

app

Ruby Type: String | Default Value: 'name'

The name of the application as it appears in the /Volumes directory, if it differs from the resource block name.

checksum

Ruby Type: String

The sha256 checksum of the .dmg file to download.

destination

Ruby Type: String | Default Value: /Applications

The directory to copy the .app into.

dmg_name

Ruby Type: String

The name of the .dmg file if it differs from that of the app, or if the name has spaces.

dmg_passphrase

Ruby Type: String

Specify a passphrase to be used to decrypt the .dmg file during the mount process.

file

Ruby Type: String

The full path to the .dmg file on the local system.

headers

Ruby Type: Hash, nil | Default Value: nil

Allows custom HTTP headers (like cookies) to be set on the remote_file 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

owner

Ruby Type: String

The system user that should own the package installation.

package_id

Ruby Type: String

The package ID that is registered with pkgutil when a pkg or mpkg is installed.

source

Ruby Type: String

The remote URL that is used to download the .dmg file, if specified.

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

type

Ruby Type: String | Default Value: app

The type of package.

volumes_dir

Ruby Type: String

The directory under /Volumes where the dmg is mounted, if it differs from the name of the .dmg file.
