1. Deploy the spark-history-server helm chart on Linode Kubernetes Engine


    To deploy the spark-history-server Helm chart on Linode Kubernetes Engine using Pulumi, you would go through the following steps:

    1. Set up a new Pulumi project and stack if you haven't already.
    2. Configure Pulumi to use the linode provider for deploying resources to the Linode cloud platform.
    3. Ensure that you have a Kubernetes cluster up and running on Linode Kubernetes Engine (LKE). If not, you can create one using Pulumi.
    4. Once you have a cluster, configure Pulumi to use the Kubernetes provider to interact with the cluster.
    5. Use the kubernetes.helm.v3.Chart resource from the kubernetes package to deploy the spark-history-server chart to your LKE cluster.

    Let's put this into a Pulumi program written in TypeScript. The program assumes that you've already created a Linode Kubernetes Engine cluster and have the kubeconfig file necessary to interact with the cluster. The kubeconfig should be set either in your environment or directly in the Pulumi program (although it is not recommended to hard-code the kubeconfig in the program for security reasons).

    import * as k8s from "@pulumi/kubernetes"; const clusterName = "my-lke-cluster"; // Replace with the actual cluster name const kubeconfig = "<YOUR_KUBECONFIG_CONTENT>"; // Typically set via environment variable const sparkHistoryServerChart = new k8s.helm.v3.Chart("spark-history-server", { chart: "spark-history-server", version: "x.y.z", // Specify the chart version you want to deploy fetchOpts: { repo: "https://helm-repo-url.com", // Replace with the correct Helm repo URL for the spark-history-server chart }, }, { provider: new k8s.Provider("k8s-provider", { kubeconfig }) }); // Export the Chart name of the deployed spark-history-server export const sparkHistoryServerChartName = sparkHistoryServerChart.metadata.name;

    In this program:

    • We import the Kubernetes package from Pulumi's SDK to use Kubernetes-related resources.
    • We define a Chart resource that Pulumi will use to install the spark-history-server helm chart into the cluster.
    • Ensure to replace "https://helm-repo-url.com" with the actual Helm repository URL which hosts the spark-history-server chart.
    • Replace "x.y.z" with the specific version of the chart you wish to deploy.
    • For security and configurability, the kubeconfig is usually set via an environment variable using process.env.KUBECONFIG or another configuration mechanism, instead of hard-coding it in the script.
    • The provider configuration object { kubeconfig } instructs the Pulumi Kubernetes provider to connect to your Linode Kubernetes Engine cluster using the provided kubeconfig.
    • Finally, we export the name of the Chart deployment for easy reference, which can be used to query the deployment status with commands like kubectl.

    Remember, Pulumi programs are declarative; it describes the desired state of the resources. When you run pulumi up, Pulumi will perform the necessary steps to achieve the state described in your program.

    Make sure to replace placeholders like <YOUR_KUBECONFIG_CONTENT> with actual values before running the program. The kubeconfig can be obtained from your Linode Kubernetes Engine cluster's dashboard or through the Linode CLI.

    This program will configure Pulumi to deploy the spark-history-server chart to your LKE cluster using the Helm package. You can run this program with the Pulumi CLI by first running pulumi stack init to create a new stack and then pulumi up to deploy the resources.
