Deploy the ibmcloud-operator helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the IBM Cloud Operator helm chart on OpenShift, we will use Pulumi with the kubernetes package. This package allows us to handle Kubernetes resources, including Helm charts, within our Pulumi program. We will need to have access to an OpenShift cluster, along with kubectl configured to interact with it.

Pulumi works with Helm through the Chart resource. This resource can deploy a Helm chart from a repository, a local path, or directly from the chart definition. For the IBM Cloud Operator, we typically fetch it from a Helm chart repository where it's hosted.

Below is a TypeScript program that demonstrates how to deploy the IBM Cloud Operator helm chart to an OpenShift cluster using Pulumi.

First, we import the necessary modules from the Pulumi library:

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

Next, we'll instantiate a new Helm Chart resource that will deploy the IBM Cloud Operator. For this, we'll need to specify the repository URL where the chart is located, the name of the chart, and potentially any specific configurations that the chart allows. If the IBM Cloud Operator chart requires specific values or configurations, these can be supplied via the values property.

Here is the code to create the helm chart representation in Pulumi:

// Create a new instance of the Helm chart.
// Ensure that you have added the specific repository hosting the IBM Cloud Operator.
// Replace `<version>` with the desired chart version.
const ibmCloudOperatorChart = new k8s.helm.v3.Chart("ibmcloud-operator", {
    repo: "ibm-cloud-operator-repo",
    chart: "ibmcloud-operator",
    version: "<version>", // specify the chart version
    namespace: "default", // specify the namespace where you want to deploy
    // If there are specific configurations you want to set for IBM Cloud Operator, you can specify them in `values`.
    values: {
        // For example, if the chart allows setting a custom service account name:
        // serviceAccount: {
        //     create: true,
        //     name: "ibmcloud-operator-service-account"
        // }
        // Provide other values as needed.
    }
}, { provider: <kubernetes_provider> }); // Specify the kubernetes provider if not using the default one.

Replace <version> with the version number of the IBM Cloud Operator Helm chart you wish to deploy, and <kubernetes_provider> with the Pulumi Kubernetes provider if you are not using the default provider.

You will also need to configure the Kubernetes provider to point to your OpenShift cluster:

// Configuring a provider to point to the OpenShift cluster, if needed.
const openshiftProvider = new k8s.Provider("openshiftProvider", {
    kubeconfig: "<kubeconfig>", // Your OpenShift cluster's kubeconfig
});

Replace <kubeconfig> with the actual kubeconfig content or file path of your OpenShift cluster configuration.

Lastly, if there are any important outputs from the deployment that can be exported, such as service endpoints or status, they can be added at the end of the Pulumi program.

// Optionally, export any needed values from the chart.
export const chartName = ibmCloudOperatorChart.status.namespace;

This basic Pulumi program can be further customized to suit specific needs, such as setting up dependencies between resources, integrating with other cloud services, or applying custom transformations to the resources before they are deployed.

When you run this program using pulumi up, Pulumi will perform the deployment, and the resources defined within our program will be created in the OpenShift cluster.

Make sure you have Pulumi installed and configured for your environment. For detailed information on how to set up Pulumi and authenticate with your Kubernetes cluster, refer to the official Pulumi Getting Started guide.
