Configure Azure CNI networking in Azure Kubernetes Service (AKS)

• An Azure account with an active subscription. Create an account.

• An Azure account with an active subscription. Create an account.

• Azure Cli or Azure PowerShell.

  You can install Azure PowerShell locally to run the cmdlets. The steps in this article require Azure PowerShell module version 5.4.1 or later. Run Get-Module -ListAvailable Az to find your installed version. If you need to upgrade for a specific OS, see macOS, Windows, or Linux.

  If you run PowerShell locally, run Connect-AzAccount -Environment AzureChinaCloud to connect to Azure.

• An Azure account with an active subscription. Create an account.

• If you prefer to run CLI reference commands locally, install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.

  • If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For other sign-in options, see Sign in with the Azure CLI.

  • When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.

  • Run az version to find the version and dependent libraries that are installed. To upgrade to the latest version, run az upgrade.

1. Sign in to the Azure portal.
2. On the Azure portal home page, select Create a resource.

     • Resource group: Select Create new, enter a resource group name, such as test-rg, and then select Ok.
   • Under Cluster details:
     • Kubernetes cluster name: Enter a cluster name, such as aks-cluster.
     • Region: Select East US 2.
5. Select Next > Next to get to the Networking tab.
6. For Container networking, select Azure CNI Node Subnet.
7. Select Review + create > Create.

When you create an AKS cluster with Azure PowerShell, you can also configure Azure CNI networking.

Use New-AzAksCluster to create an AKS cluster with default settings and Azure CNI networking:

## Create a resource group for the AKS cluster. ##
$rg = @{
    Name = "test-rg"
    Location = "eastus2"
}
New-AzResourceGroup @rg

$net = @{
      NetworkPlugin = "azure"
      ResourceGroupName = "test-rg"
      Name = "aks-cluster"
}
New-AzAksCluster @net

When you create an AKS cluster with the Azure CLI, you can also configure Azure CNI networking.

Use az aks create with the --network-plugin azure argument to create a cluster with advanced networking:

az group create \
    --name test-rg \
    --location chinanorth3

az aks create \
    --resource-group test-rg \
    --name aks-cluster \
    --network-plugin azure \
    --generate-ssh-keys
