1. Deploy the odpi-egeria-lab helm chart on Opensshift

    TypeScript

    Deploying a Helm chart to an OpenShift cluster involves a few steps, including setting up the OpenShift cluster, initializing Helm, and then deploying the chart itself. Since OpenShift is Kubernetes-based, Pulumi provides a Kubernetes provider that can interact with any Kubernetes cluster, including OpenShift.

    Below is a step-by-step guide in TypeScript on how to deploy a Helm chart to an OpenShift cluster using Pulumi.

    Step 1: Import Required Pulumi Libraries

    We'll need to import the Kubernetes library for Pulumi, which allows us to interact with Kubernetes resources.

    Step 2: Initialize Kubernetes Provider

    The Kubernetes provider is initialized with the context of the OpenShift cluster. This requires that you have configured access to your OpenShift cluster via kubectl.

    Step 3: Deploy Helm Chart

    We'll use the helm.sh/v3.Chart resource provided by Pulumi Kubernetes provider to deploy the Helm chart. We specify the chart name, version, and any values that need to be overridden.

    Pulumi Program for Deployment

    Now, let's write the actual program in TypeScript:

    import * as k8s from "@pulumi/kubernetes"; // Initialize a Kubernetes Provider pointing to the OpenShift cluster. // Make sure your `kubectl` is configured to connect to your OpenShift cluster. const openshiftProvider = new k8s.Provider("openshift-provider", { // You may specify the kubeconfig or context here if necessary. }); // Define the Helm chart details. const chart = new k8s.helm.v3.Chart("odpi-egeria-lab-chart", { // Replace with the correct repository and chart information repo: "egeria", chart: "odpi-egeria-lab", // Specify the Helm chart version you want to deploy version: "x.x.x", // Include any custom values for the Helm chart values: { // Custom values set here, for example // serviceType: "LoadBalancer" }, }, { provider: openshiftProvider }); // Export the endpoint of the deployed application export const chartEndpoint = chart.getResourceProperty("v1/Service", "odpi-egeria-lab-service", "status");

    This program will deploy the odpi-egeria-lab Helm chart to your OpenShift cluster. Replace "egeria" with the actual repository name if it's different, and replace "x.x.x" with the actual version of the chart you wish to deploy. You will also need to adjust the values mapping if the chart requires any specific configurations.

    Additional Notes

    • This program assumes you have access to the OpenShift cluster with kubectl and that your kubeconfig file is set up correctly. Pulumi uses the same configuration as kubectl to connect to your Kubernetes cluster.
    • The odpi-egeria-lab Helm chart should exist in the specified Helm repository (egeria). If the chart is located in a different repository, you'll need to add the repository or adjust the provided names.
    • The export statement is used to output the service endpoint after deployment, which can be accessed using the Pulumi CLI with the command pulumi stack output chartEndpoint.
