1. Deploy the spark-history-server helm chart on Azure Kubernetes Service (AKS)


    To deploy the spark-history-server Helm chart on Azure Kubernetes Service (AKS), you'll need to follow several steps:

    1. Set up an AKS cluster: First, we need to provision an AKS cluster where the Helm chart will be deployed. We will define the resources required for the cluster such as node pools, networking, and identity configurations.

    2. Install Helm on your machine: Helm is the package manager for Kubernetes and you need it installed to manage Kubernetes applications. Helm uses charts, which are packages of pre-configured Kubernetes resources.

    3. Deploy the Helm chart: After setting up AKS, you will use Helm to deploy the spark-history-server onto the cluster.

    Here's a TypeScript Pulumi program that:

    • Creates an Azure Kubernetes Service (AKS) cluster.
    • Deploys the spark-history-server chart onto the AKS cluster.
    import * as azure from '@pulumi/azure'; import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; import * as azuread from "@pulumi/azuread"; import * as random from "@pulumi/random"; // Create an Azure AD application for AKS const aksApp = new azuread.Application("aks", {}); // Create a service principal for the application so AKS can act on behalf of the application const aksSp = new azuread.ServicePrincipal("aksSp", { applicationId: aksApp.applicationId }); // Create the AD service principal password const aksSpPassword = new azuread.ServicePrincipalPassword("aksSpPassword", { servicePrincipalId: aksSp.id, endDate: "2099-01-01T00:00:00Z", }); // Generate an SSH key for the AKS nodes const sshKey = new random.RandomPassword("sshKey", { length: 20, special: false, }); // Now, let's create an AKS cluster. const resourceGroup = new azure.core.ResourceGroup("aksResourceGroup"); const aksCluster = new azure.containerservice.KubernetesCluster("aksCluster", { resourceGroupName: resourceGroup.name, defaultNodePool: { name: "aksagentpool", nodeCount: 3, vmSize: "Standard_D2_v2", }, dnsPrefix: `${pulumi.getStack()}-kube`, linuxProfile: { adminUsername: "aksuser", sshKey: { keyData: sshKey.result, }, }, servicePrincipal: { clientId: aksApp.applicationId, clientSecret: aksSpPassword.value, }, kubernetesVersion: "1.18.14", }); // Export the kubeconfig export const kubeconfig = aksCluster.kubeConfigRaw; // Create a k8s provider using the generated kubeconfig const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: aksCluster.kubeConfigRaw, }); // Deploy the spark-history-server chart using the Helm Chart resource const sparkHistoryServerChart = new k8s.helm.v3.Chart("spark-history-server", { chart: "spark-history-server", version: "<version>", // Replace with specific chart version fetchOpts: { repo: "http://<helm-chart-repository>", // Specify the repository URL here }, }, { provider: k8sProvider }); // Export the necessary values or endpoints if required export const sparkHistoryServerServiceIP = sparkHistoryServerChart.getResourceProperty("v1/Service", "<service-name>", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Understanding the Code

    • The first section sets up the Azure AD application and service principal, which are required for AKS to interact with other Azure resources securely.
    • The SSH key is generated for secure communication with AKS nodes.
    • The azure.containerservice.KubernetesCluster resource is used to create the AKS cluster with a specified version, node count, and VM sizes for the nodes.
    • We export the kubeconfig of the AKS cluster, which is used by kubectl and other tools to interact with the Kubernetes cluster.
    • The k8s.Provider resource initializes a Kubernetes provider with the kubeconfig that we get from the AKS cluster.
    • The k8s.helm.v3.Chart resource represents the Helm chart that we want to deploy. You need to specify the chart name, chart version, and Helm repo URL that hosts the spark-history-server chart.
    • Finally, we export the service IP of the Spark History Server which you can use to access the Spark UI. Replace <service-name> with the actual name of the service created by the chart.


    • Ensure you have Pulumi CLI installed.
    • Helm must be installed on your local machine.
    • Azure CLI should be installed and configured.
    • Replace <version> with the chart version and http://<helm-chart-repository> with the actual Helm repository URL where the spark-history-server chart is located.
    • Replace <service-name> with the actual Kubernetes service name created by the helm chart for the spark-history-server.

    Run the Pulumi program with the usual pulumi up. After successfully running the program, the AKS cluster will be set up and the spark-history-server will be deployed on it.
