1. Deploy the ibm-websphere-liberty helm chart on Opensshift

    TypeScript

    To deploy the IBM WebSphere Liberty Helm chart on Red Hat OpenShift using Pulumi, we're going to use Pulumi's Kubernetes provider. Pulumi integrates with Helm by providing a resource type that can deploy Helm charts into a Kubernetes cluster.

    In this task, we will follow these steps:

    1. Set up and configure Pulumi to access our Kubernetes cluster on OpenShift.
    2. Use the kubernetes.helm.v3.Chart resource to deploy the IBM WebSphere Liberty Helm chart to the OpenShift cluster.

    Before attempting to deploy, ensure you have:

    • A running OpenShift cluster.
    • The oc command-line tool installed and configured to access your cluster.
    • Helm chart details for IBM WebSphere Liberty, such as repository URL and chart name.
    • Pulumi CLI installed on your local machine.

    Below is a Pulumi TypeScript program that you can use to deploy IBM WebSphere Liberty on OpenShift. Run this script using Pulumi CLI and it will perform the deployment for you:

    import * as k8s from "@pulumi/kubernetes"; // Define the name of the Helm chart const chartName = "ibm-websphere-liberty"; // Define the repository where the Helm chart is located const chartRepo = "https://repo-name/path-to-repo"; // Replace with the actual URL of the Helm chart repository // Define the version of the Helm chart const chartVersion = "1.2.3"; // Use the correct version number for your Helm chart // Create a new instance of the Helm chart const ibmWebsphereLibertyChart = new k8s.helm.v3.Chart(chartName, { repo: chartRepo, chart: chartName, version: chartVersion, // If needed, you can provide custom values to the Helm chart by specifying the values property // values: { ... } // Namespace where the chart will be installed namespace: "websphere-liberty", // Specify the namespace or use the default namespace // OpenShift typically requires additional configuration for certain workloads, such as // assigning security context constraints and ensuring the correct policies are in place. // These additional configurations may be specified using transformations or by providing // a custom values file. }); // Export the Helm chart's resources export const resources = ibmWebsphereLibertyChart.resources;

    This script sets up a Pulumi Kubernetes Helm Chart resource. Let me walk you through what the script does:

    1. We import the Pulumi Kubernetes package required to interact with the Kubernetes cluster.
    2. We specify the chart name, repository, and version accordingly. You will need to replace these placeholder strings with the accurate details from the Helm chart you want to deploy.
    3. We create an instance of the Helm chart using the Chart class, specifying the namespace, repository information, and any additional values that need to be configured for the chart.
    4. We export the resources created by the Helm chart, which can be helpful for querying the resources in the OpenShift cluster.

    To apply this Pulumi program:

    1. Save the script above as index.ts within a new Pulumi project directory.
    2. Initialize a Pulumi stack if you haven't already (pulumi stack init).
    3. Use the Pulumi CLI to run pulumi up to deploy your Helm chart on OpenShift.

    When you run the above steps, Pulumi will communicate with your OpenShift cluster and deploy the IBM WebSphere Liberty Helm chart according to the configurations specified.
