1. Deploy the keda-operator helm chart on Opensshift


    Deploying the KEDA (Kubernetes Event-Driven Autoscaling) operator on an OpenShift cluster involves creating a Helm Chart that contains all the necessary configurations for the KEDA operator. Pulumi's kubernetes package provides facilities to work with Helm charts through the Chart and Release resources.

    Here's how you would set up a program to deploy the KEDA operator using a Helm Chart in TypeScript with Pulumi.

    Firstly, ensure that you have Pulumi installed and configured for your environment.

    Then, initialize a new Pulumi project with the TypeScript template if you haven't already done so:

    pulumi new typescript

    Next, add the necessary dependencies for the @pulumi/kubernetes package in your Pulumi project:

    npm install @pulumi/kubernetes

    Now, let me walk you through a simple Pulumi program that deploys the KEDA operator Helm chart on an OpenShift cluster.

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes namespace for KEDA const kedaNamespace = new k8s.core.v1.Namespace("keda", { metadata: { name: "keda" // The name of the namespace where KEDA will be installed } }); // Define the Helm Chart for KEDA operator const kedaChart = new k8s.helm.v3.Chart("keda-operator", { chart: "keda", // The name of the chart version: "2.4.0", // Specify the version of the chart namespace: kedaNamespace.metadata.name, // Deploy the chart in the created namespace fetchOpts: { repo: "https://kedacore.github.io/charts", // The repository where the chart is hosted } }, { dependsOn: [kedaNamespace] }); // Ensure the namespace is created before the Helm chart is deployed export const kedaOperatorChart = kedaChart;

    This Pulumi program starts by importing the @pulumi/kubernetes package, which provides the means to interact with Kubernetes resources including namespaces and Helm charts.

    Next, a new Kubernetes namespace called "keda" is created. Namespaces help you organize different environments within your Kubernetes cluster.

    Then, we declare a Helm Chart with k8s.helm.v3.Chart where we specify the details for the KEDA operator chart. We provide the chart name (which is "keda"), the chart version, and the repository where the Helm chart is hosted.

    Note the dependsOn option on the Helm Chart instantiation. This ensures that the Kubernetes Namespace is created before Pulumi tries to deploy the Helm Chart in it.

    Lastly, we export the kedaOperatorChart as an export from our Pulumi program, which is helpful if we ever want to reference this chart's resources from another Pulumi stack.

    To run this Pulumi program, you'll navigate to the directory where your Pulumi project is initialized and run the following commands:

    pulumi up

    Running pulumi up will prompt you to confirm the actions before it proceeds with the deployment. Once confirmed, Pulumi will deploy the KEDA operator into your OpenShift cluster.

    Keep in mind that this program assumes you have an existing OpenShift cluster where you are authenticated, and your kubeconfig is set up correctly for Pulumi to interact with the cluster.
