1. Deploy the sample-app helm chart on Azure Kubernetes Service (AKS)

    TypeScript

    To deploy the sample-app helm chart on Azure Kubernetes Service (AKS), you will need to perform a few steps. The process involves:

    • Setting up an AKS cluster
    • Installing the Helm Chart onto the AKS cluster

    I'll provide a TypeScript program using Pulumi to accomplish these tasks. This program takes advantage of the azure-native Pulumi provider, which interfaces natively with Azure resources, and the kubernetes provider, which allows managing Kubernetes resources, including Helm Charts.

    Here is what each part of the program does:

    1. Setting up an AKS Cluster: We first declare an AKS cluster resource. This AKS cluster will be the Kubernetes environment where your Helm chart will be deployed.
    2. Installing the Helm Chart: Once the AKS cluster is provisioned, we use Pulumi's Kubernetes provider to install the sample-app Helm chart onto that AKS cluster.

    Program Overview

    Before running this program, ensure you have set up the Azure CLI and authenticated with Azure. Pulumi uses your Azure CLI credentials to provision resources, and you should also have the Pulumi CLI installed and set up.

    Now let's proceed with the Pulumi program:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Declare the AKS cluster resource const resourceGroup = new azure_native.resources.ResourceGroup("aksResourceGroup"); const aksCluster = new azure_native.containerservice.ManagedCluster("aksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 1, // You can change the count according to the required replicas maxPods: 110, mode: "System", // Change to 'User' if you have specific node tainting requirements name: "agentpool", osType: "Linux", vmSize: "Standard_DS2_v2", // This is a standard SKU, you can change it based on your needs }], dnsPrefix: "aksk8s", // Replace with your DNS prefix kubernetesVersion: "1.18.14", // Replace with the version you prefer location: resourceGroup.location, }); // Step 2: Install the Helm chart const k8sProvider = new k8s.Provider("k8s", { kubeconfig: aksCluster.kubeConfigRaw, }); const sampleAppChart = new k8s.helm.v3.Chart("sample-app", { chart: "sample-app", // Specify the Helm repository URL if the chart is not in the default Helm repo // repo: "http://<helm-repo-url>", version: "1.0.0", // Replace with the actual chart version namespace: "default", fetchOpts: { repo: "http://<helm-repo-url>", // Replace with the actual Helm repo URL }, }, { provider: k8sProvider }); // Export the Kubeconfig to access your cluster export const kubeConfig = aksCluster.kubeConfigRaw;

    Explanation

    • We first create a new Azure resource group called aksResourceGroup. Resource groups in Azure are used to group together related resources for management convenience.

    • Then we define the AKS cluster aksCluster, providing configurations like the resource group name, the agent pool profile, DNS prefix, and the desired Kubernetes version.

    • We create a new instance of the Kubernetes provider k8sProvider by passing in the kubeconfig of the AKS cluster we just set up. This provider instance allows us to interact with the AKS cluster.

    • Lastly, we install the sample-app Helm chart to the default namespace of the AKS cluster we provisioned. You will need to replace <helm-repo-url> with the URL of the Helm repository that contains your sample-app chart.

    • We export the kubeconfig of the AKS cluster, which you can use to interact with your Kubernetes cluster using kubectl.

    Note that you have to replace placeholders with actual values that reflect your environment and the Helm chart you wish to deploy.

    After you have the program ready, you run it with the Pulumi CLI. This will prompt Pulumi to provision the resources as defined.

    Keep in mind that Helm charts are versioned, so you must specify the version you wish to deploy, and that the Kubernetes provider must have access to a Helm repository where the sample-app chart is hosted.

    With this program, you can configure and deploy cloud resources in a declarative manner, using the benefits of infrastructure as code. The use of Pulumi can also extend to managing the entire lifecycle of your cloud resources.
