1. Deploy the hadoop-yarn helm chart on Azure Kubernetes Service (AKS)

    TypeScript

    To deploy a Helm chart on an Azure Kubernetes Service (AKS) cluster using Pulumi, you need to follow these steps:

    1. Create an AKS Cluster: Utilize the Pulumi resource to create a new AKS cluster, where your Helm chart will be deployed.
    2. Set up a Kubernetes Provider: Configure Pulumi to communicate with the newly created AKS cluster, in order to manage Kubernetes resources.
    3. Deploy the Helm Chart: With a Chart resource from the Pulumi Kubernetes provider, you will specify the Hadoop-YARN Helm chart details for deployment.

    Below is a Pulumi program in TypeScript that demonstrates these steps. This program assumes you have already set up and authenticated Pulumi with Azure.

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an AKS Cluster const resourceGroup = new azure_native.resources.ResourceGroup("myResourceGroup"); const k8sCluster = new azure_native.containerservice.ManagedCluster("myAksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, vmSize: "Standard_DS2_v2", maxPods: 110, mode: "System", name: "agentpool", osType: "Linux" }], dnsPrefix: "myakscluster", linuxProfile: { adminUsername: "adminuser", ssh: { publicKeys: [{ keyData: "ssh-rsa ...", }], }, }, identity: { type: "SystemAssigned", }, resourceGroupName: resourceGroup.name, kubernetesVersion: "1.20.9" }); // Output the kubeconfig export const kubeconfig = pulumi.all([resourceGroup.name, k8sCluster.name]).apply(([rgName, clusterName]) => azure_native.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, }) .apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()) ); // Step 2: Use the Pulumi Kubernetes Provider to interact with the AKS cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // Step 3: Deploy the Hadoop-YARN Helm chart using the Pulumi Kubernetes provider const hadoopYarnChart = new k8s.helm.v3.Chart("hadoop-yarn", { chart: "hadoop", version: "3.0.0", // Replace with the desired chart version fetchOpts: { repo: "https://charts.bitnami.com/bitnami", // The repository containing the Hadoop chart }, }, { provider: k8sProvider }); // Export the Helm chart resources export const hadoopYarnChartResources = hadoopYarnChart.resources;

    In this program:

    • We define a resource group for the AKS cluster within the specified location.
    • We create a Managed AKS cluster, specifying the node count and size, the Linux profile for access, and the Kubernetes version.
    • We output the Kubernetes configuration, which we then use to set up a provider to manage Kubernetes resources within the AKS cluster.
    • We use Pulumi's Helm package to deploy a Helm chart, specifying the chart name, version, and the repository.

    Don't forget to replace "ssh-rsa ..." with your actual SSH public key data and adjust the chart and version to the Helm chart for Hadoop-YARN you wish to deploy.

    The created hadoopYarnChart will deploy the specified version of the Hadoop-YARN Helm chart that is stored in the Bitnami repository to the AKS cluster. The resources related to the Helm chart deployment, such as pods, deployments, and services, are exported through hadoopYarnChartResources for your reference.

    Remember, before running this program you should have your Pulumi CLI and Azure provider set up and properly authenticated. You would then run this program using Pulumi's CLI commands pulumi up to create the resources and pulumi destroy to delete them if needed.

    For more detailed information on Pulumi's Kubernetes package, you can check the Kubernetes (k8s) Pulumi package. For details on Azure-specific resources, refer to the Azure Pulumi package.
