Arcus

A library that provides a clean API into Cloudstack REST calls. Also included is a CLI tool for making Cloudstack REST calls

Installation

Add this line to your application's Gemfile:

gem 'arcus'

And then execute:

$ bundle

Or install it yourself as:

$ gem install arcus

Usage

Cloudstack REST commands are read in from the commands.xml file. This provides a list of required and optional arguments for each Cloudstack command. Each Cloudstack command is split up into an action and a target, for instance listVirtualMachines becomes: [action -> list, target -> VirtualMachine]. The arcus will create a dynamic class based on the name of the target and a method named after the action. So you can do the following:

vms = VirtualMachine.new.list.fetch

vms will be a object containing the results of "listvirtualmachinesresponse"

Other "response_types" are allowed, for example:

vms = VirtualMachine.new.list.fetch(:yaml)
vms = VirtualMachine.new.list.fetch(:xml)
vms = VirtualMachine.new.list.fetch(:prettyxml)
vms = VirtualMachine.new.list.fetch(:json)
vms = VirtualMachine.new.list.fetch(:prettyjson)

Each of these calls will return a string representation in the format specified.

You can also give arguments to the "action" method.  For example:

vms = VirtualMachine.new.list({id: 1}).fetch(:json)

will produce the http call -> /client/api?id=1&response=xml&command=listVirtualMachines
