1. Deploy the hadoop-yarn helm chart on Kubernetes


    To deploy the Hadoop YARN Helm chart on Kubernetes using Pulumi, you will utilize the kubernetes.helm.v3.Chart resource provided by Pulumi's Kubernetes provider. This resource enables you to deploy Helm charts into a Kubernetes cluster.

    Below is a step-by-step TypeScript program that demonstrates how to deploy a Helm chart.

    Step 1: Import Required Packages

    First, you need the @pulumi/kubernetes package to access Kubernetes resources in Pulumi. If you haven't yet installed the package in your project, you need to run npm install @pulumi/kubernetes.

    Step 2: Create a Helm Chart Resource

    Next, you instantiate a Helm chart with the kubernetes.helm.v3.Chart class. You need to define the chart name and other optional parameters such as values to customize the deployment, the namespace where you want to deploy, and the version of the chart.

    Step 3: Export any Necessary Outputs

    At the end of the Pulumi program, you may want to export certain outputs such as the service URL or other pertinent information ties to the resources you created.

    Here's the full program:

    import * as kubernetes from "@pulumi/kubernetes"; // Initialize a new Kubernetes Helm chart for Hadoop YARN const hadoopYarnChart = new kubernetes.helm.v3.Chart("hadoop-yarn", { // Specify the repository details and the chart name. // Note: You will need to replace "REPO_URL" with the actual repository URL where the Hadoop YARN chart is hosted. // You may also need to specify the version of the chart you wish to deploy and provide any custom `values` or `fetchOpts` as needed. repo: "REPO_URL", chart: "hadoop-yarn", // Optional: Specify namespace and other chart values. namespace: "default" // You can change this to the desired Kubernetes namespace. // values: { /* Custom values for the Helm chart */ }, // version: "CHART_VERSION", // Optional: specify the exact chart version }, { provider: kubernetesProvider }); // Optional: if you have a specific K8s provider to use // Export the chart's status as an output. export const chartStatus = hadoopYarnChart.status;

    Before running this Pulumi program, ensure you've set up your Pulumi stack and connected it to the Kubernetes cluster where you want to deploy the Hadoop YARN chart.

    To run the program:

    1. Save this code in a file, e.g., index.ts.
    2. Ensure the Kubernetes context is set to your target cluster where Pulumi can interact with it.
    3. Run pulumi up to execute the Pulumi program. This will deploy the specified Helm chart to the Kubernetes cluster.

    Note: You need to replace "REPO_URL" with the actual Helm repository URL where the Hadoop YARN chart is located and "CHART_VERSION" with the specific Helm chart version you want to deploy.

    Remember to review the Helm chart's documentation to understand the values you can customize. This is important because the chart might require certain configurations specific to your environment or requirements.
