1. Deploy the zeppelin helm chart on Opensshift

    TypeScript

    To deploy the Zeppelin helm chart on OpenShift using Pulumi, we will use the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. The Helm Chart resource allows us to deploy a Helm chart into a Kubernetes cluster, which in our case is an OpenShift cluster.

    Before we begin, ensure that you have Pulumi and Helm installed on your machine, and that you are logged into the OpenShift cluster where the deployment will take place. The Kubernetes context should be set to the relevant OpenShift cluster context.

    The following TypeScript program demonstrates how to deploy the Zeppelin Helm chart:

    1. Set up a new Pulumi project and install the necessary dependencies.
    2. Create a new file named index.ts and include the following Pulumi code.
    3. Execute the Pulumi program to deploy Zeppelin to your OpenShift cluster.

    Here's the TypeScript program that performs the deployment:

    import * as k8s from "@pulumi/kubernetes";

// Define the namespace where the Helm chart will be deployed.
const namespace = new k8s.core.v1.Namespace("zeppelin-namespace", {
    metadata: { name: "zeppelin" },
});

// Deploy the Zeppelin Helm chart.
const zeppelinChart = new k8s.helm.v3.Chart("zeppelin-chart", {
    namespace: namespace.metadata.name,
    chart: "zeppelin",
    version: "0.1.0", // Replace with the desired chart version
    // If the chart is from a custom Helm repo, specify the 'repo' option,
    // for instance: repo: "https://helm-repository-url/"
    // Otherwise, add the repository using the Helm CLI with `helm repo add`.
    values: {
        // Include any custom values you want to set for Zeppelin here.
        // Example: service.type: "ClusterIP"
    },
});

// Export the name of the namespace
export const zeppelinNamespace = namespace.metadata.name;

    Before running this program:

    • Replace the version value with the version of the Zeppelin Helm chart you wish to deploy. If you are using a specific chart repository, ensure you add the repo option with the chart's repository URL.
    • The values object should include any configuration parameters specific to the Zeppelin chart that you need to customize.
    • Ensure your Pulumi stack is correctly configured to communicate with your OpenShift cluster. You can review the Pulumi documentation for information on configuring Kubernetes provider if you have not done this before.

    To run the program, execute:

    pulumi up

    This command will start Pulumi's deployment process and prompt you for confirmation before proceeding with the actual deployment to the OpenShift cluster. After confirming, Pulumi will deploy the Zeppelin Helm chart according to the settings defined in the TypeScript program.

    Once the deployment is complete, you will see the outputs in the Pulumi CLI, which include the namespace where the Helm chart was deployed. You can access Zeppelin on OpenShift using the service URL provided by the Helm chart output.
