securegit

A resource defines the desired state for a single configuration item present on a node that is under management by chef. A resource collection---one (or more) individual resources---defines the desired state for the entire node. During a chef-client run, the current state of each resource is tested, after which the chef-client will take any steps that are necessary to repair the node and bring it back into the desired state.

Use the securegit resource to manage source control resources that exist in a private git repository. This is a LWRP that used the scp_git resource to achieve the git related tasks, substituting certain attributes where necessary.

Syntax

A securegit resource block manages source control resources that exist in a private git repository:

securegit 'app_name' do
  destination '/path/to/app_name'
  repository 'node[:app_name][:git_repository]'
  revision 'node[:app_name][:git_revision]'
  private_key_file '/path/to/private_key_file'
  action :sync
end

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

git 'name' do
  additional_remotes         Hash
  checkout_branch            String
  depth                      Integer
  destination                String # Required
  enable_checkout            TrueClass, FalseClass
  enable_submodules          TrueClass, FalseClass
  environment                Hash
  group                      String, Integer
  notifies                   # see description
  private_key                String
  private_key_file           String
  reference                  String
  remote                     String
  repository                 String
  revision                   String
  subscribes                 # see description
  timeout                    Integer
  user                       String, Integer
  action                     Symbol # defaults to :sync if not specified
end

where

• securegit is the resource
• name is the name of the resource block
• destination is teh 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
• additional_remotes, checkout_branch, depth, destination, enable_checkout, enable_submodules, environment, group, reference, remote, repository, revision, timeout, and user are properties of this resource, with the ruby type shown.

Actions

This resource has the following actions:

Action	Description
: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.
:nothing	Define a resource block that does nothing until it is notified by another resource to take action. When 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.
:delete	Delete the source, as well as any additional helper files required for enabling this securegit resource.

Properties

This resource has the following properties:

Property	Description
additional_remotes	Ruby Type: Hash See Git resource documentation.
checkout_branch	Ruby Type: String See Git resource documentation.
depth	Ruby Type: Integer See Git resource documentation.
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. Any helper files required for enabling this securegit resource will be placed in the parent directory of the source code destination.
enable_checkout	Ruby Types: TrueClass, FalseClass See Git resource documentation.
enable_submodules	Ruby Types: TrueClass, FalseClass See Git resource documentation.
environment	Ruby Type: Hash A Hash of environment variables in the form of {"ENV_VARIABLE" => "VALUE"}. (These variables must exist for a command to be run successfully.) Note The git provider automatically sets the ENV['HOME'] and ENV['GIT_SSH'] environment variables. To override this behavior and provide different values, add ENV['HOME'] and/or ENV['GIT_SSH'] to the environment Hash.
group	Ruby Types: String, Integer See Git resource documentation.
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]', Symbol See Chef documenation.
private_key	Ruby Type: String A string containing the entire private key value. This value will be written to a helper file in the parent directory of the destination as specified above. Note If private_key is specified, the private_key_file value will be ignored.
private_key_file	Ruby Type: String A string containing the path to a private key file that already exists locally. Note If the private_key value is speified, this property will be ignored.
reference	Ruby Type: String See Git resource documenation.
remote	Ruby Type: String See Git resource documentation.
repository	Ruby Type: String See Git resource documentation.
retries	Ruby Type: Integer See Git resource documenation.
retry_delay	Ruby Type: Integer See Git resource documenation.
revision	Ruby Type: String See Git resource documentation.
subscribes	Ruby Type: Symbol, 'Chef::Resource[String]', Symbol See Chef documenation.
timeout	Ruby Type: Integer See Git resource documentation.
user	Ruby Types: String, Integer See Git resource documentation.

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/opscode-cookbooks.

Use the a private key string

securegit 'couch' do
  destination '/path/to/couch'
  repository 'git://git.apache.org/couchdb.git'
  revision 'master'
  private_key 'Contents of private key'
  action :sync
end

Use a private key file already stored locally

securegit 'couch' do
  destination '/path/to/couch'
  repository 'git://git.apache.org/couchdb.git'
  revision 'master'
  private_key_file '/path/to/private/key_file'
  action :sync
end
