Azure Networking SDK for Go

The Azure SDK for Go provides comprehensive libraries to manage and interact with Azure Networking services. This includes creating and configuring virtual networks, subnets, network interfaces, public IP addresses, load balancers, and more.

Key Features

  • Simplified resource creation and management.
  • Asynchronous operations for scalability.
  • Robust error handling and retries.
  • Integration with Azure Resource Manager (ARM).

Getting Started

To use the networking modules, you first need to initialize an Azure client. Ensure you have the necessary authentication set up (e.g., Azure CLI login, environment variables, or managed identity).


package main

import (
	"context"
	"fmt"
	"log"
	"os"

	"github.com/Azure/azure-sdk-for-go/sdk/azidentity"
	"github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/network/armnetwork/v2"
)

func main() {
	subscriptionID := os.Getenv("AZURE_SUBSCRIPTION_ID")
	if subscriptionID == "" {
		log.Fatal("AZURE_SUBSCRIPTION_ID environment variable not set")
	}

	cred, err := azidentity.NewDefaultAzureCredential(nil)
	if err != nil {
		log.Fatalf("Failed to create Azure credential: %v", err)
	}

	ctx := context.Background()

	// Example: Creating a Network Client
	networkClient, err := armnetwork.NewVirtualNetworksClient(subscriptionID, cred, nil)
	if err != nil {
		log.Fatalf("Failed to create network client: %v", err)
	}

	fmt.Println("Azure Network client initialized successfully.")
	// Now you can use networkClient to interact with Azure Networking services
}

Virtual Networks

Manage your Azure Virtual Networks (VNets) and subnets. VNets provide a private network space in Azure for your resources.

VirtualNetworksClient.NewCreateOrUpdatePager

github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/network/armnetwork/v2

Creates or updates a virtual network.

Example: 

// Assuming networkClient is initialized
vnetName := "myVNet"
resourceGroupName := "myResourceGroup"
location := "eastus"

vnetParams := armnetwork.VirtualNetwork{
	Location: to.Ptr(location),
	Properties: &armnetwork.VirtualNetworkPropertiesFormat{
		AddressSpace: &armnetwork.AddressSpace{
			AddressPrefixes: []*string{to.Ptr("10.0.0.0/16")},
		},
	},
}

poller, err := networkClient.NewCreateOrUpdatePager(ctx, resourceGroupName, vnetName, vnetParams, nil)
if err != nil {
	log.Fatalf("Failed to start virtual network creation: %v", err)
}
_, err = poller.PollUntilDone(ctx, nil)
if err != nil {
	log.Fatalf("Failed to create virtual network: %v", err)
}
log.Printf("Virtual network '%s' created successfully.", vnetName)

Network Interfaces

Configure Network Interface Controllers (NICs) for your Virtual Machines, allowing them to communicate within Azure and with the internet.

NetworkInterfacesClient.NewCreateOrUpdatePager

github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/network/armnetwork/v2

Creates or updates a network interface.

Example: 

// Assuming networkInterfacesClient is initialized
nicName := "myNIC"
resourceGroupName := "myResourceGroup"
location := "eastus"
vnetName := "myVNet"
subnetName := "default"

nicParams := armnetwork.Interface{
	Location: to.Ptr(location),
	Properties: &armnetwork.InterfacePropertiesFormat{
		IPConfigurations: []*armnetwork.InterfaceIPConfiguration{
			{
				Name: to.Ptr("ipconfig1"),
				Properties: &armnetwork.InterfaceIPConfigurationPropertiesFormat{
					Subnet: &armnetwork.Subnet{
						ID: to.Ptr(fmt.Sprintf("/subscriptions/%s/resourceGroups/%s/providers/Microsoft.Network/virtualNetworks/%s/subnets/%s", subscriptionID, resourceGroupName, vnetName, subnetName)),
					},
				},
			},
		},
	},
}

poller, err := networkInterfacesClient.NewCreateOrUpdatePager(ctx, resourceGroupName, nicName, nicParams, nil)
if err != nil {
	log.Fatalf("Failed to start NIC creation: %v", err)
}
_, err = poller.PollUntilDone(ctx, nil)
if err != nil {
	log.Fatalf("Failed to create NIC: %v", err)
}
log.Printf("Network Interface '%s' created successfully.", nicName)

Public IP Addresses

Assign static or dynamic public IP addresses to your Azure resources for inbound and outbound connectivity.

PublicIPAddressesClient.BeginCreateOrUpdate

github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/network/armnetwork/v2

Creates or updates a public IP address.

Example: 

// Assuming publicIPAddressesClient is initialized
pipName := "myPublicIP"
resourceGroupName := "myResourceGroup"
location := "eastus"

pipParams := armnetwork.PublicIPAddress{
	Location: to.Ptr(location),
	SKU: &armnetwork.PublicIPAddressSKU{
		Name: to.Ptr(armnetwork.PublicIPAddressSKUNameStandard),
	},
	Properties: &armnetwork.PublicIPAddressPropertiesFormat{
		PublicIPAllocationMethod: to.Ptr(armnetwork.IPAllocationMethodStatic),
	},
}

poller, err := publicIPAddressesClient.BeginCreateOrUpdate(ctx, resourceGroupName, pipName, pipParams, nil)
if err != nil {
	log.Fatalf("Failed to start public IP creation: %v", err)
}
result, err := poller.PollUntilDone(ctx, nil)
if err != nil {
	log.Fatalf("Failed to create public IP: %v", err)
}
log.Printf("Public IP Address '%s' created with IP: %s", pipName, *result.Properties.IPAddress)

Load Balancers

Distribute network traffic across multiple virtual machines using Azure Load Balancer.

LoadBalancersClient provides methods to create, update, and manage load balancers.

Application Gateways

Deploy a fully managed web application firewall (WAF) and scalable Layer 7 load balancer.

ApplicationGatewaysClient offers functionalities for managing application gateways.

Virtual Network Gateways

Connect your on-premises networks to Azure VNets using VPN Gateway or ExpressRoute.

VirtualNetworkGatewaysClient is used for managing these gateways.

Network Security Groups

Filter network traffic to and from Azure resources in an Azure virtual network.

SecurityGroupsClient is available for managing Network Security Groups and their rules.
