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. Application gateways, virtual network gateways and virtual network gateway connections aren’t properly supported yet - it’s a known issue that will be resolved soon.

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:

Ruby require 'azure_mgmt_network'

After that you should be ready to start using SDK!

Authentication

Ruby # Create authentication objects token_provider = MsRestAzure::ApplicationTokenProvider.new(tenant_id, client_id, secret) credentials = MsRest::TokenCredentials.new(token_provider)

To get tenant_id, client_id and secret for your Azure application visit Azure portal or copy them from the powershell script from the article mentioned above.

Creating new virtual network

```Ruby # Include SDK modules to ease access to network classes. include Azure::ARM::Network include Azure::ARM::Network::Models

Create a client - a point of access to the API and set the subscription id

client = NetworkResourceProviderClient.new(credentials) client.subscription_id = subscription_id

Create a model for new virtual network

props = VirtualNetworkPropertiesFormat.new

address_space = AddressSpace.new address_space.address_prefixes = [‘10.0.0.0/16’] props.address_space = address_space

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

sub_prop = SubnetPropertiesFormat.new sub_prop.address_prefix = ‘10.0.2.0/24’

sub = Subnet.new sub.name = ‘new_subnet’ sub.properties = sub_prop

props.subnets = [sub]

params = VirtualNetwork.new params.location = ‘westus’ params.properties = props

promise = client.virtual_networks.create_or_update(‘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:

Ruby result = promise.value!

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

Ruby 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:

```Ruby 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.

Running tests

Adding env variables

To run the tests you would need to set the following environment variables with your real Azure data:

  • AZURE_TENANT_ID=”your tenant id or domain”
  • AZURE_CLIENT_ID=”your client id / application id”
  • AZURE_CLIENT_SECRET=”your service principal secret”
  • AZURE_SUBSCRIPTION_ID=”your subscription id”

  • run_long_tasks - set this to ‘1’ only if you would like to run time consuming tests like VM creation.

Starting tests

Just run ‘rspec’ command from the current gem folder.

Contribution

All the SDK code was generated by tool ‘AutoRest’ - https://github.com/Azure/autorest So if you have found a bug or have an idea for a new feature - suggest, discuss and contribute it into the AutoRest repository. After that SDK maintainers will update the sources and the gem.
