1. Deploy the spark-history-server helm chart on Opensshift


    To deploy the Spark History Server Helm chart on an OpenShift cluster using Pulumi, you'll need to use the Pulumi Kubernetes provider, which allows you to deploy Kubernetes resources and Helm charts to a cluster. The kubernetes.helm.v3.Chart resource is responsible for deploying Helm charts.

    In this program, I'll demonstrate how to deploy a Helm chart to an existing OpenShift cluster. I'm assuming you already have access to the OpenShift cluster and have configured kubectl to communicate with it. You must have the Helm chart details for the Spark History Server, such as the chart version and repository. If any specific configurations are needed, they can be provided as values to the chart.

    Before you run this Pulumi program, make sure you've installed the Pulumi CLI and the required packages.

    Here's how you might write a Pulumi program to deploy the Spark History Server Helm chart:

    1. Define the chart and its configurations.
    2. Deploy it to your OpenShift cluster.

    Let's walk through the program:

    import * as k8s from '@pulumi/kubernetes'; // Create an instance of the Kubernetes provider connected to your existing OpenShift cluster. const kubeconfig = ... // Your kubeconfig contents or file path const provider = new k8s.Provider("openshift-provider", { kubeconfig: kubeconfig, }); // Deploy the Spark History Server Helm chart using the Chart resource. const sparkHistoryServer = new k8s.helm.v3.Chart("spark-history-server", { // Replace with the correct repository and chart name for Spark History Server. repo: "repo-name", chart: "spark-history-server", version: "chart-version", // Specify the chart version if needed. // Pass the necessary values to configure the Spark History Server chart. values: { // These values depend on the Helm chart's value keys and the specific configuration you want. }, // Ensure this namespace exists in your OpenShift cluster or create it as part of your Pulumi program. namespace: "spark-history-namespace", }, { provider }); // Export the URL for Spark History Server (if applicable). // This assumes the service is of type LoadBalancer and the Spark History Server Helm chart exposes a service. export const sparkHistoryServerUrl = sparkHistoryServer.getResourceProperty("v1/Service", "spark-history-server", "status") .apply(status => { const ingress = status.loadBalancer.ingress[0]; if(ingress.ip) { return `http://${ingress.ip}`; } else if(ingress.hostname) { return `http://${ingress.hostname}`; } return "Service URL not available"; });

    What does this program do?

    • It sets up a Pulumi Kubernetes provider to interface with your OpenShift cluster using the provided kubeconfig.
    • It deploys the Spark History Server Helm chart to the specified namespace on the cluster. Before running the program, you need to ensure that this exact Helm chart (with the name spark-history-server) exists, or adjust the chart and repo properties accordingly.
    • It optionally exports the LoadBalancer IP or hostname for the deployed service, assuming the Helm chart creates a service of type LoadBalancer.

    Be sure to replace placeholders (e.g., repo-name, chart-version, spark-history-namespace, and values in the values field) with actual values relevant to your Spark History Server Helm chart and your specific configurations.
