subversion

Use the subversion resource to manage source control resources that exist in a Subversion repository.

Note

This resource is often used in conjunction with the deploy resource.

Syntax

A subversion resource block manages source control resources that exist in a Subversion repository:

subversion 'CouchDB Edge' do
  repository 'http://svn.apache.org/repos/asf/couchdb/trunk'
  revision 'HEAD'
  destination '/opt/mysources/couch'
  action :sync
end

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

subversion 'name' do
  destination                String # defaults to 'name' if not specified
  group                      String, Integer
  notifies                   # see description
  provider                   Chef::Provider::Scm::Subversion
  repository                 String
  revision                   String
  subscribes                 # see description
  svn_arguments              String
  svn_info_args              String
  svn_password               String
  svn_username               String
  timeout                    Integer
  user                       String, Integer
  action                     Symbol # defaults to :sync if not specified
end

where

• subversion is the resource
• name is the name of the resource block and also (when the destination property is not specified) the location in which the source files will be placed and/or synchronized with the files under source control management
• :action identifies the steps the chef-client will take to bring the node into the desired state
• destination, group, provider, repository, revision, svn_arguments, svn_info_args, svn_password, svn_username, timeout, and user are properties of this resource, with the Ruby type shown. See “Properties” section below for more information about all of the properties that may be used with this resource.

Actions

This resource has the following actions:

:checkout

Clone or check out the source. When a checkout is available, this provider does nothing.

:export

Export the source, excluding or removing any version control artifacts.

:force_export

Export the source, excluding or removing any version control artifacts and force an export of the source that is overwriting the existing copy (if it exists).

: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.

:sync

Default. Update the source to the specified version, or get a new clone or checkout. This action causes a hard reset of the index and working tree, discarding any uncommitted changes.

Properties

This resource has the following properties:

destination

Ruby Type: String

The location path to which the source is to be cloned, checked out, or exported. Default value: the name of the resource block See “Syntax” section above for more information.

group

Ruby Types: String, Integer

The system group that is responsible for the checked-out code.

ignore_failure

Ruby Types: TrueClass, FalseClass

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

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 notifiy 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:

: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

provider

Ruby Type: Chef Class

Optional. Explicitly specifies a provider.

repository

Ruby Type: String

The URI for the Subversion repository.

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.

revision

Ruby Type: String

A branch, tag, or commit to be synchronized with git. This can be symbolic, like HEAD or it can be a source control management-specific revision identifier. Default value: HEAD.

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.

A timer specifies the point during the chef-client run at which a notification is run. The following timers are available:

: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

svn_arguments

Ruby Type: String

The extra arguments that are passed to the Subversion command.

svn_info_args

Ruby Type: String

Use when the svn info command is used by the chef-client and arguments need to be passed. The svn_arguments command does not work when the svn info command is used.

svn_password

Ruby Type: String

The password for a user that has access to the Subversion repository.

svn_username

Ruby Type: String

The user name for a user that has access to the Subversion repository.

timeout

Ruby Type: Integer

The amount of time (in seconds) to wait for a command to execute before timing out. When this property is specified using the deploy resource, the value of the timeout property is passed from the deploy resource to the subversion resource.

user

Ruby Types: String, Integer

The system user that is responsible for the checked-out code.

Examples

The following examples demonstrate various approaches for using resources in recipes. If you want to see examples of how Chef uses resources in recipes, take a closer look at the cookbooks that Chef authors and maintains: https://github.com/chef-cookbooks.
