Getting Started

Install the rubygem package

You can install the azure rubygem package directly.

gem install azure

Download Source Code

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

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:

bundle install

Generate Documentation

Running the this 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. After that, you can get the information you need to configure Storage and Service Bus from the Windows Azure Portal.

There are two ways you can set up the connections:

1. via code
2. via environment variables

Via Code

• Against Windows Azure Services in the cloud

  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 2 properties to use Service Management
      config.publish_settings_file = "<path to your *.publishsettings file>"
      config.subscription_id      = "<your subscription id>"
  end

• Against local Emulator (Windows Only)

  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

    AZURE_API_URL = <The endpoint URL of the Windows Azure management service>
    

• Against local Emulator (Windows Only)

  • Storage

    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

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
