# Windows Azure SDK for Ruby [![Build Status](https://travis-ci.org/WindowsAzure/azure-sdk-for-ruby.png?branch=dev)](https://travis-ci.org/WindowsAzure/azure-sdk-for-ruby)


This project provides a Ruby package that makes it easy to access and manage Windows Azure Services like Storage, Service Bus and Virtual Machines.

# Library Features
* Storage
    * Blobs
        * create, list, and delete containers, work with container metadata and permissions, list blobs in container
        * create block and page blobs (from a stream, a file, or a string), work with blob blocks and pages, delete blobs
        * work with blob properties, metadata, leases, snapshot a blob
    * Tables
        * create and delete tables
        * create, query, insert, update, merge, and delete entities
    * Queues
        * create, list, and delete queues, and work with queue metadata
        * create, get, peek, update, delete messages
* Service Bus
    * Queues
        * create, list and delete queues

* Virtual Network Management
    * List VNet
    * Create VNet 
    	* via parameters
    	* via xml file
		
# Useful commands for certificate operations

* Currently the sdk supports *.pem or *.pfx (passwordless pfx) for service management operations. Following are the steps discussed on various cert operations.

	* To create pfx, simply download the publishsettings file for your subscription, copy the contents of Management Certificate from the publishsettings and save it in a file and name the file
	  as your cert.pfx. This pfx will be a passwordless pfx which can be supplied as a cert parameter for Service Management Commands
	  
	* Using the following openssl commands to extract the pem file and pass the pem file as management cert parameter.
		
		* To get only private key from pfx use Openssl.exe pkcs12 -in cert.pfx -nocerts -out cert.pem
 
		* To remove passphrase from the above private key use Openssl.exe rsa -in cert.pem -out certprivnopassword.pem
 
		* To extract both public & private keys from pfx use Openssl.exe pkcs12 -in cert.pfx -out certprivpub.pem
		
		* To extract only public key from pem use Openssl x509 -inform pem -in certprivpub.pem -pubkey -out certpub.pem -outform pem 
		
		* Finally copy the public key & private key to a file *.pem and pass that pem file to management cert parameter.
		
	* To extract pem from custom certificate, export the pfx, follow the above steps to convert to pem and pass that pem file to management cert parameter. 

# Supported Ruby Versions

* Ruby 1.9.3
* Ruby 2.0

**Notice** that Ruby 2.0 x64 on Windows is not supported due to the [lack of nokogiri](https://github.com/sparklemotion/nokogiri/issues/864).

# Getting Started

## Install the rubygem package

You can install the azure rubygem package directly.

```bash
gem install azure
```

## Download Source Code

To get the source code of the SDK via **git** just type:

```bash
git clone https://github.com/WindowsAzure/azure-sdk-for-ruby.git
cd ./azure-sdk-for-ruby
```
Then, run bundler to install all the gem dependencies:

```bash
bundle install
```

## Generate Documentation

Running the command ``rdoc`` will generate the API documentation in the `./doc` directory.

## Setup Connection

You can use this SDK against the Windows Azure Services in the cloud, or against the local Storage Emulator if you are on Windows. Service Bus and Windows Azure Service Management emulation are not supported. Of course, to use the Windows Azure Services in the cloud, you need to first [create a Windows Azure account](http://www.windowsazure.com/en-us/pricing/free-trial/). After that, you can get the information you need to configure Storage and Service Bus from the [Windows Azure Portal](https://manage.windowsazure.com).

There are two ways you can set up the connections:

1. [via code](#via-code)
2. [via environment variables](#via-environment-variables)

### Via Code
* Against Windows Azure Services in the cloud

  ```ruby
  require "azure"

  Azure.configure do |config|
      # Configure these 2 properties to use Storage
      config.storage_account_name = "<your azure storage account name>"
      config.storage_access_key   = "<your azure storage access key>"
      # Configure these 3 properties to use Service Bus
      config.sb_namespace         = "<your azure service bus namespace>"
      config.sb_access_key        = "<your azure service bus access key>"
      config.sb_issuer            = "<your azure service bus issuer>"
      # Configure these 3 properties to use Service Management
      config.management_certificate = "<path to your *.pem or *.pfx>". We support passwordless pfx & pem cert formats.
      config.subscription_id        = "<your Subscriptionid>"
      config.management_endpoint    = "https://management.core.windows.net"
  end
  ```
* Against local Emulator (Windows Only)
  ```ruby
  require "azure"

  Azure.configure do |config|
      # Configure these 2 properties to use local Storage Emulator
      config.storage_account_name = "devstoreaccount1"
      config.storage_access_key   = "Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw=="
      config.storage_blob_host    = "http://127.0.0.1:10000/devstoreaccount1"
      config.storage_queue_host   = "http://127.0.0.1:10001/devstoreaccount1"
      config.storage_table_host   = "http://127.0.0.1:10002/devstoreaccount1"
      # Local Service Bus Emulator is not supported
      # Local Service Management emulation is not supported
  end
  ```
### Via Environment Variables
* Against Windows Azure Services in the cloud
  * Storage

    ```bash
    AZURE_STORAGE_ACCOUNT = <your azure storage account name>
    AZURE_STORAGE_ACCESS_KEY = <your azure storage access key>
    ```
  * Service Bus

    ```bash
    AZURE_SERVICEBUS_NAMESPACE = <your azure service bus namespace>
    AZURE_SERVICEBUS_ACCESS_KEY = <your azure service bus access key>
    AZURE_SERVICEBUS_ISSUER = <your azure service bus issuer>
    ```
  * Service Management
  
    ```bash
	
	AZURE_MANAGEMENT_CERTIFICATE = <path to *.pem or *.pfx> . We support passwordless pfx & pem cert formats.
    AZURE_SUBSCRIPTION_ID = <your subscription ID>
	AZURE_MANAGEMENT_ENDPOINT = <The endpoint URL of Windows Azure management service>
   
    ```
* Against local Emulator (Windows Only)
  * Storage

    ```bash
    AZURE_STORAGE_ACCOUNT = devstoreaccount1
    AZURE_STORAGE_ACCESS_KEY = Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==
    AZURE_STORAGE_BLOB_HOST = http://127.0.0.1:10000/devstoreaccount1
    AZURE_STORAGE_QUEUE_HOST = http://127.0.0.1:10001/devstoreaccount1
    AZURE_STORAGE_TABLE_HOST = http://127.0.0.1:10002/devstoreaccount1
    ```
  * Service Bus: not supported
  * Service Management: not supported
## Run Test
You can use the following commands to run:
* all the tests: ``rake test``
* a specific suite of tests: ``rake test:integration:blob``
* one particular test file: ``ruby -I"lib:test" "<path of the test file>"``
# Usage
