Kubernetes Cluster on Azure

The Azure Kubernetes Cluster template scaffolds a Pulumi project that provisions a managed Azure Kubernetes Service (AKS) cluster inside a new Azure Virtual Network with three subnets. Worker nodes are deployed with private IP addresses for improved security and spread across multiple availability zones for resilience.

Using this template

To use this template to deploy your own Kubernetes cluster, make sure you’ve installed Pulumi and configured your Azure credentials, then create a new project using the template in the language of your choice:

$ mkdir my-k8s-cluster && cd my-k8s-cluster
$ pulumi new kubernetes-azure-typescript

Alternatively, you can create and configure a new project with this template (kubernetes-azure-typescript) in Pulumi Cloud.

$ mkdir my-k8s-cluster && cd my-k8s-cluster
$ pulumi new kubernetes-azure-python

Alternatively, you can create and configure a new project with this template (kubernetes-azure-python) in Pulumi Cloud.

$ mkdir my-k8s-cluster && cd my-k8s-cluster
$ pulumi new kubernetes-azure-go

Alternatively, you can create and configure a new project with this template (kubernetes-azure-go) in Pulumi Cloud.

$ mkdir my-k8s-cluster && cd my-k8s-cluster
$ pulumi new kubernetes-azure-csharp

Alternatively, you can create and configure a new project with this template (kubernetes-azure-csharp) in Pulumi Cloud.

$ mkdir my-k8s-cluster && cd my-k8s-cluster
$ pulumi new kubernetes-azure-yaml

Alternatively, you can create and configure a new project with this template (kubernetes-azure-yaml) in Pulumi Cloud.

Follow the prompts to complete the new-project wizard. When it’s done, you’ll have a complete Pulumi project that’s ready to deploy and configured with the most common settings. Feel free to inspect the code in index.js index.ts __main__.py main.go Program.cs Program.fs Program.vb App.java Pulumi.yaml for a closer look.

Deploying the project

You must supply two values to deploy the cluster. You can input both through the new-project wizard:

mgmtGroupId

The object ID of an existing Azure AD group that will serve as the cluster administrator.

sshPubKey

The contents of the public key used for SSH access to the cluster nodes.

Once the project is created, you can deploy it with pulumi up:

$ pulumi up

When the deployment completes, Pulumi exports the following stack output values:

rgname

The name of the Azure Resource Group containing the Kubernetes cluster resources.

vnetName

The name of the Azure Virtual Network used for worker nodes, apps, and workloads.

clusterName

The name of the AKS cluster.

kubeconfig

The cluster’s kubeconfig file, which you can use with kubectl to access and communicate with your cluster.

Output values like these are useful in many ways, most commonly as inputs for other stacks or related cloud resources.

Customizing the project

Projects created with the Kubernetes Cluster template expose the following configuration settings:

numWorkerNodes

The number of nodes in your cluster. Defaults to 3.

kubernetesVersion

The version of Kubernetes used in your AKS cluster. Defaults to 1.24.3.

prefixForDns

The unique DNS prefix for your AKS cluster. Defaults to pulumi.

nodeVmSize

The VM instance type used to run your nodes. Defaults to Standard_DS2_v2.

All of these settings are optional and may be adjusted either by editing the stack configuration file directly (by default, Pulumi.dev.yaml) or by changing their values with pulumi config set:

$ pulumi config set numWorkerNodes 5
$ pulumi up

Cleaning up

You can cleanly destroy the stack and all of its infrastructure with pulumi destroy:

$ pulumi destroy
