1. Deploy the nginx-files-server helm chart on Azure Kubernetes Service (AKS)


    To deploy the nginx-files-server Helm chart on Azure Kubernetes Service (AKS), you'll be taking the following steps through Pulumi:

    1. Create an AKS cluster: You'll use the Azure Native Pulumi provider to provision an AKS cluster. This is where your Helm chart will be deployed.

    2. Install the Helm Chart: Pulumi supports Helm charts as a resource type via the Chart class, allowing you to deploy existing Helm charts.

    Here's a step-by-step Pulumi TypeScript program for deploying a Helm chart to an AKS cluster:


    Before running the Pulumi program, ensure you have the following prerequisites met:

    • Pulumi CLI installed.
    • Azure CLI installed and configured with the necessary permissions to create resources.
    • Appropriate Pulumi program set-up (new project, stack, and config).

    The Pulumi Program

    We begin by importing the necessary packages for both creating the AKS cluster and deploying the Helm chart.

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // The Pulumi program's main function. async function main() { // [Kubernetes Cluster Creation] - Step 1: Declare the resource group where the AKS cluster will be deployed. const resourceGroup = new azure.resources.ResourceGroup("resourceGroup"); // [Kubernetes Cluster Creation] - Step 2: Define the AKS cluster itself with some basic configurations const aksCluster = new azure.containerservice.ManagedCluster("aksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, // Define the number of nodes (VMs) in the Kubernetes cluster maxPods: 110, mode: "System", name: "agentpool", osDiskSizeGB: 30, osType: "Linux", vmSize: "Standard_DS2_v2", }], dnsPrefix: `${pulumi.getStack()}-kube`, enableRBAC: true, kubernetesVersion: "1.18.14", }); // [Kubernetes Configuration] - Step 3: Retrieve the kubeconfig output from the AKS cluster to configure the Kubernetes provider const creds = pulumi.all([resourceGroup.name, aksCluster.name]).apply(([rgName, clusterName]) => { return azure.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, }); }); const kubeconfig = creds.kubeconfigs[0].value.apply(v => Buffer.from(v, "base64").toString()); // [Helm Chart Deployment] - Step 4: Use the kubeconfig to create a Kubernetes provider instance const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // [Helm Chart Deployment] - Step 5: Deploy the nginx-files-server Helm chart using the Kubernetes provider const nginxFilesServerChart = new k8s.helm.v3.Chart("nginx-files-server", { chart: "nginx-files-server", version: "1.0.1", // Replace with the desired version of the Helm chart namespace: "default", // Deploy to the default namespace, or any namespace of your preference }, { provider: k8sProvider }); // Export the public IP for the nginx service const frontend = nginxFilesServerChart.getResourceProperty("v1/Service", "nginx-files-server", "status"); export const frontendIp = frontend.apply(status => status.loadBalancer.ingress[0].ip); } // Start the Pulumi program main();

    Please, replace the "nginx-files-server" with the correct Helm chart name you intend to deploy and adjust the version with the desired chart version.

    Running the Program

    Now, let’s run the Pulumi program by executing the following commands in the terminal in the same directory as our Pulumi program:

    1. Install the dependencies by running: npm install
    2. Create all declared resources by running: pulumi up

    Upon successful completion of the pulumi up command, you will have an AKS cluster running with the nginx-files-server deployed.


    Here's what each part of the program is doing:

    • Resource Group: A logical container for your Azure resources. In this case, it's where the AKS cluster will live.
    • AKS Cluster: An instance of Azure Kubernetes Service. You configure the node count, the size of OS disks, the VM size, and optionally the version of Kubernetes.
    • Kubernetes Provider: This bridges the communication between Pulumi and Kubernetes, in this case using the kubeconfig of your AKS cluster to manage resources.
    • Helm Chart: The actual deployment of your nginx-files-server. This will install the Helm chart in your AKS cluster within the default namespace.

    Regarding the exported value frontendIp, once the nginx-files-server service is successfully deployed and assigned an IP by the AKS load balancer, this IP is exported by Pulumi. You can use this IP to access your nginx-files-server from your browser or API.

    Remember to manage the resources created by pulumi responsibly. Use pulumi destroy when necessary to clean up all resources to avoid incurring any unnecessary costs.
