1. Deploy the z2jh4k8s helm chart on Azure Kubernetes Service (AKS)

    TypeScript

    To deploy the z2jh4k8s Helm chart on Azure Kubernetes Service (AKS), you will need to first create an AKS cluster and then use the kubernetes.helm.v3.Chart resource to deploy the Helm chart to it.

    Here is a step-by-step guide with the corresponding TypeScript program:

    Step 1: Set Up Pulumi and Azure

    Before you begin, ensure that you have installed Pulumi and configured it with your Azure account. Follow the Pulumi installation guide and the Azure setup if you haven't set up your environment.

    Step 2: Import Required Packages

    Start by importing the necessary Pulumi packages in your TypeScript program. These will allow you to interact with Azure resources and the Kubernetes API within Pulumi.

    Step 3: Create an AKS Cluster

    With Pulumi, you define your desired infrastructure using TypeScript code, which Pulumi then provisions on the cloud provider—Azure in this case. You use the azure-native.containerservice.ManagedCluster resource to create an AKS cluster.

    Step 4: Deploy the Helm Chart

    Once the AKS cluster is provisioned, you will use Pulumi's kubernetes.helm.v3.Chart resource to deploy the z2jh4k8s Helm chart. You'll need to specify the chart details, including any custom values you want to override.

    Step 5: Execute the Program

    You execute the Pulumi program by running pulumi up in the command line. This command will show you a preview of the resources that Pulumi will create or modify. If you confirm, Pulumi will proceed to apply the changes.

    Now, let's dive into the TypeScript program.

    import * as pulumi from "@pulumi/pulumi";
import * as azure from "@pulumi/azure";
import * as k8s from "@pulumi/kubernetes";

// Step 1: Create an AKS cluster
const aksCluster = new azure.containerservice.KubernetesCluster("aksCluster", {
    // Configure the AKS Cluster settings here
    defaultNodePool: {
        // Define your node pool settings here
        name: "default",
        nodeCount: 2,
        vmSize: "Standard_D2_v2",
    },
    dnsPrefix: "aksk8s",
    // Ensure you use a valid location and resource group name
    location: azure.Locations.WestUS2,
    resourceGroupName: "myResourceGroup",
    // Change these to your own SSH key and Azure AD details
    linuxProfile: {
        adminUsername: "adminuser",
        sshKey: {
            keyData: "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD3b...user@hostname",
        },
    },
    servicePrincipal: {
        clientId: "myClientId",
        clientSecret: "myClientSecret",
    },
});

// Step 2: Define the Helm Chart from AKS deployed
const chart = new k8s.helm.v3.Chart("z2jh4k8s", {
    // Ensure you use the right chart name and repository
    chart: "z2jh4k8s",
    version: "0.1.0", // Specify the correct chart version
    fetchOpts: {
        repo: "http://helm-repository-url/", // Provide the Helm chart repository URL
    },
}, { provider: aksCluster.provider });

// Step 3: Export the kubeconfig if needed
export const kubeconfig = aksCluster.kubeConfigRaw;

    Resource Explanation:

    • azure.containerservice.KubernetesCluster: This Pulumi resource creates an AKS cluster. You must configure the node pool, location, SSH access, and service principal with the necessary details.

    • k8s.helm.v3.Chart: This resource deploys a Helm chart onto a Kubernetes cluster. You must specify the chart name, repository, and version.

    • kubeconfig: Exporting the Kubernetes configuration allows you to interact with your AKS cluster using kubectl or any Kubernetes ecosystem tools compatible with kubeconfig files.

    Running the Program:

    1. Save the above code to a file named index.ts in a new Pulumi project's directory.
    2. Navigate to the directory where you saved the index.ts file in your command line.
    3. Run pulumi stack init to create a new stack, if you haven't already done so.
    4. Run pulumi config set azure:location WestUS2 to set the location for your resources.
    5. If you choose to set up secret values like the service principal client secret, use the command pulumi config set --secret.
    6. Run pulumi up to preview and deploy the changes.

    After successfully executing your Pulumi program, the AKS cluster is created and the z2jh4k8s Helm chart is deployed to the cluster. If needed, you can manage your deployed Kubernetes workloads with the exported kubeconfig file.
