spice

Spice is a zesty Chef API wrapper. Its primary purpose is to let you easily integrate your apps with a (Chef)[http://opscode.com/chef] server easily. Spice provides support for the Chef API

Installation

Install this beast via Rubygems:

gem install spice

Of course, You can always grab the source from http://github.com/danryan/spice.

Configuration

Spice has four configuration variables:

Spice.server_url    # default: http://localhost:4000
  Spice.chef_version	# default: 0.10.4. Should be set to the version you have
Spice.client_name   # default: nil. Must be set to a valid admin Chef client
Spice.key_file      # default: nil. Must be set to a file path

To connect to a Chef server at https://chef.example.com:5000 with the "admin" API client, throw this somewhere your app can initialize:

Spice.server_url = "http://chef.example.com:4000"
Spice.client_name = "admin"
Spice.key_file = "/path/to/keyfile.pem"

Say you had a Chef server v0.10.4 running locally on port 4000 over HTTP, you only need to set your client_name and key_file path:

Spice.client_name = "admin"
Spice.key_file = "/path/to/keyfile.pem"

You can also use the Spice.setup block if you prefer this style:

Spice.setup do |s|
  s.server_url = "http://chef.example.com:4000"
  s.client_name = "admin"
  s.key_file = "/path/to/keyfile.pem"
end

Next, we need to create the connection object you'll use to sign your requests and pass them to the Chef server. Previous versions of Spice required you to explicitly call Spice.connect! to set up the connection object. If you use the Spice.setup block, it will call .connect! for you:

Spice.connect!

If you want to reset your config to their default values:

Spice.reset!

Deprecation notice

Explicitly setting a host, port, and scheme value has been deprecated in favor of setting a single variable, server_url, which matches the format of Chef's client config parameter, chef_server_url. The old way of defining host, port, and scheme are still currently available but will be removed from future versions.

Usage

Low-level use

Setting up spice and running Spice.connect! creates a connection object that can then be used to send requests to your Chef server, accessed via Spice.connection.

Get a list of all clients:

Spice.connection.get("/clients")

Get a specific node by the name "slappypants":

Spice.connection.get("/nodes/slappypants")

Create a new role called "awesome":

Spice.connection.post("/roles", :name => "awesome")

Make the client "sweet" an admin:

Spice.connection.put("/clients/sweet", :admin => true)

Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
Fork the project
Start a feature/bugfix branch
Commit and push until you are happy with your contribution
Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
