azure_mgmt_network

Intro

This project provides a Ruby gem for easy access to the Azure ARM Network API. With this gem you can create/update/list/delete virtual networks, subnets, load balancers and network interfaces.

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 network 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_network

and reference it in your code:

require 'azure_mgmt_network'

After that you should be ready to start using SDK!

Creating a Client

Option 1 - Using the Network Profiles

You can create a new Virtual Network using the Network profile.

# Include SDK modules to ease access to network classes.
include Azure::Network::Profiles::Latest::Mgmt
include Azure::Network::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 Network

You can create a new Virtual network using a specific version of Network, say 2017-09-01.

# Include SDK modules to ease access to compute classes.
include Azure::Network::Mgmt::V2017_09_01
include Azure::Network::Mgmt::V2017_09_01::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 = NetworkManagementClient.new(credentials)
client.subscription_id = ENV['AZURE_SUBSCRIPTION_ID']

Using the client

Once the client is initialized, we could create the virtual network.

# Create a model for new virtual network
params = VirtualNetwork.new

address_space = AddressSpace.new
address_space.address_prefixes = ['10.0.0.0/16']
params.address_space = address_space

dhcp_options = DhcpOptions.new
dhcp_options.dns_servers = %w(10.1.1.1 10.1.2.4)
params.dhcp_options = dhcp_options

sub = Subnet.new
sub.name = 'new_subnet'
sub.address_prefix = '10.0.2.0/24'

params.subnets = [sub]

params.location = 'westus'

promise = client.virtual_networks.create_or_update_async('existing_resource_group', 'new_vn', params)

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 virtual network. To get data from it:

virtual_network = result.body

p virtual_network.name # name of the new vn
p virtual_network.id # id of the new vn

Congrats, you've create new virtual network. We encourage you to try more stuff and let us know your feedback! For advanced SDK usage please reference to the spec files.
