Intro

This project provides a Ruby gem for easy access to the Azure ARM Resources API. With this gem you can create/update/list/delete resources, resource groups, resource providers and deployments.

Supported Ruby Versions

• Ruby 2+

Note: x64 Ruby for Windows is known to have some compatibility issues.

Getting started

Setting up the service principal

First of all to start interacting with the ARM resources you will need to setup a service principal. Service principal is an Azure application which allows you to authenticate to Azure and access Azure services. The detailed steps of how to setup a service principal can be found in this article: http://aka.ms/cli-service-principal. In the result of setting up service principal you will get tenant id, client id and client secret data.

Installation

install the appropriate gem:

gem install azure_mgmt_resources

and reference it in your code:

require 'azure_mgmt_resources'

After that you should be ready to start using SDK!

Creating a Client

Option 1 - Using the Resources Profiles

You can create a new resources group using the Resources profile.

# Include SDK modules to ease access to resources classes.
include Azure::Resources::Profiles::Latest::Mgmt
include Azure::Resources::Profiles::Latest::Mgmt::Models

provider = MsRestAzure::ApplicationTokenProvider.new(
       'YOUR TENANT ID',
       'YOUR CLIENT ID',
       'YOUR CLIENT SECRET')
credentials = MsRest::TokenCredentials.new(provider)

options = {
  tenant_id: 'YOUR TENANT ID',
  client_id: 'YOUR CLIENT ID',
  client_secret: 'YOUR CLIENT SECRET',
  subscription_id: 'YOUR SUBSCRIPTION ID',
  credentials: credentials
}

client = Client.new(options)

Option 2 - Using a specific version of Resources

You can create a new resources group using a specific version of Resources, say 2017-05-10.

# Include SDK modules to ease access to resources classes.
include Azure::Resources::Mgmt::V2017_05_10
include Azure::Resources::Mgmt::V2017_05_10::Models

# Note: The tenant_id, client_id, client_secret and subscription_id
# must be set using the env variables.

provider = MsRestAzure::ApplicationTokenProvider.new(
       ENV['AZURE_TENANT_ID'],
       ENV['AZURE_CLIENT_ID'],
       ENV['AZURE_CLIENT_SECRET'])
credentials = MsRest::TokenCredentials.new(provider)

client = ResourceManagementClient.new(credentials)
client.subscription_id = ENV['AZURE_SUBSCRIPTION_ID']

Using the client

Once the client is initialized, we could create the resource group.

# Create a model for resource group.
resource_group = ResourceGroup.new()
resource_group.location = 'westus'

promise = client.resource_groups.create_or_update_async('new_test_resource_group', resource_group)

The SDK method returns a promise which you can utilize depending on your needs. E.g. if you need to get result immediately via sync blocking call - do the following:

result = promise.value!

If you need to follow async flow - provide a block which will be executed in off main thread:

promise = promise.then do |result|
  # Handle the result
end

In both cases you're returned an instance of MsRestAzure::AzureOperationResponse which contains HTTP requests/response objects and response body. Response body is a deserialized object representing the received information. In case of code above - newly created resource group. To get data from it:

resource_group = result.body

p resource_group.name # 'new_test_resource_group'
p resource_group.id   # the id of resource group

Congrats, you've create an ARM resource group. We encourage you to try more stuff and let us know your feedback!
