Creating an AKS Cluster Tutorial


Azure Kubernetes Service (AKS) is a managed container orchestration service provided by Microsoft Azure. It simplifies the deployment, management, and scaling of containerized applications using Kubernetes. In this tutorial, you will learn how to create an AKS cluster, which is the foundation for running your containerized workloads in a production-ready environment.

Step 1: Set Up Azure Environment

Before creating an AKS cluster, ensure that you have an Azure subscription and the necessary permissions to create resources. Follow these steps to set up your Azure environment:

  1. Create an Azure account if you don't have one.
  2. Create a resource group to contain your AKS cluster and related resources.
  3. Install the Azure CLI or use the Azure Portal for command execution.
  4. Log in to your Azure account using the Azure CLI or the Azure Portal.

Step 2: Create an AKS Cluster

Once your Azure environment is set up, you can create an AKS cluster. Use the Azure CLI or the Azure Portal to create the cluster. Here's an example CLI command to create an AKS cluster:

az aks create --resource-group myResourceGroup --name myAKSCluster --node-count 3 --generate-ssh-keys

This command creates an AKS cluster with three nodes and generates SSH keys for secure access to the cluster.

Step 3: Connect to the AKS Cluster

After the AKS cluster is created, you need to connect to it to manage your applications and workloads. Use the Azure CLI to get the necessary credentials for cluster access. Here's an example CLI command to retrieve the AKS cluster credentials:

az aks get-credentials --resource-group myResourceGroup --name myAKSCluster

This command retrieves the cluster credentials and configures the Kubernetes command-line tool (kubectl) to communicate with the AKS cluster.

Common Mistakes to Avoid

  • Not specifying the correct resource group or cluster name during cluster creation.
  • Choosing an inappropriate node count or VM size for the cluster, leading to performance or cost issues.
  • Missing or incorrect permissions for the Azure account used to create the cluster.

Frequently Asked Questions (FAQs)

  1. What is the minimum node count for an AKS cluster?

    An AKS cluster can have a minimum of one node, but it is recommended to have at least three nodes for production workloads to ensure high availability and fault tolerance.

  2. How do I upgrade the Kubernetes version in an existing AKS cluster?

    You can upgrade the Kubernetes version in an existing AKS cluster using the Azure CLI or Azure Portal. The upgrade process ensures minimal downtime for your applications.

  3. Can I scale the AKS cluster after it is created?

    Yes, you can scale the AKS cluster by increasing or decreasing the node count using the Azure CLI or Azure Portal. The scaling process automatically manages the addition or removal of nodes.

  4. Can I use Azure Policies to enforce governance and compliance in AKS?

    Yes, you can use Azure Policies to define and enforce governance and compliance rules for AKS clusters, ensuring adherence to organizational standards and best practices.

  5. Can I integrate Azure Active Directory with AKS for authentication and authorization?

    Yes, AKS supports integration with Azure Active Directory (AAD) for authentication and authorization, providing granular control over access to the cluster and its resources.


In this tutorial, you learned how to create an AKS cluster in Azure Kubernetes Service. Setting up your Azure environment, creating the cluster, and connecting to it are essential steps in preparing your environment for running containerized workloads. With your AKS cluster up and running, you can now deploy and manage your applications using Kubernetes, taking advantage of the scalability, reliability, and ease of management provided by AKS.
