For more information on how to lock down your private AKS cluster and filter outbound traffic, see:
An Azure Firewall used to control the egress traffic from the private AKS cluster. User node pool hosting user workloads and artifacts. The worker nodes have node taint which prevents application pods from beings scheduled on this node pool. System node pool hosting only critical system pods and services. The private AKS cluster is composed of a:. The private AKS cluster uses a user-defined managed identity to create additional resources like load balancers and managed disks in Azure. VmSubnet used by the jumpbox virtual machine and private endpoints. UserSubnet used by the AKS user node pool. SystemSubnet used by the AKS system node pool. A new virtual network with three subnets:. AzureFirewallSubnet used by Azure Firewall. AzureBastionSubnet used by Azure Bastion. A hub virtual network with two subnets:. The architecture is composed of the following elements: The following picture provides a more detailed view of the infrastructure on Azure. The following picture shows the high-level architecture created by the Terraform modules included in this sample: If you want to deploy a private AKS cluster using a public DNS zone to simplify the DNS resolution of the API Server to the private IP address of the private endpoint, you can use this project under my GitHub account or on Azure Quickstart Templates. In addition, the sample creates a private endpoint to access all the managed services deployed by the Terraform modules via a private IP address: For more information on Azure Private Links, see What is Azure Private Link? 
For more information, see Create a private Azure Kubernetes Service cluster. Virtual network peering requires you to plan your network CIDR ranges to ensure there are no overlapping ranges. Express Route and VPNs add costs and require additional networking complexity. Use an Express Route or VPN connection.Ĭreating a virtual machine in the same virtual network as the AKS cluster or in a peered virtual network is the easiest option.
See the section below for more information on this option.
Use a virtual machine in a separate network and set up Virtual network peering. Create a virtual machine in the same Azure Virtual Network (VNet) as the AKS cluster. There are several options for establishing network connectivity to the private cluster. This sample deploys a jumpbox virtual machine in the hub virtual network peered with the virtual network that hosts the private AKS cluster. 
Hence, to manage the API server, you will need to use a virtual machine that has access to the AKS cluster's Azure Virtual Network (VNet). In a private AKS cluster, the API server endpoint is not exposed via a public IP address. Azure DevOps Pipelines to automate the deployment and undeployment of the entire infrastructure on multiple environments on the Azure platform.

Terraform as infrastructure as code (IaC) tool to build, change, and version the infrastructure on Azure in a safe, repeatable, and efficient way.This sample shows how to create a private AKS clusters using: Create a private Azure Kubernetes Service cluster using Terraform and Azure DevOps
