1. Deploy the twistlock-defender helm chart on Opensshift


    Deploying the Twistlock Defender Helm Chart on OpenShift requires several steps. First, you need to ensure that you have access to an OpenShift cluster and that helm is installed on your local machine or wherever you plan to run these commands.

    To consult and search for official charts, you might visit Helm's official chart repository or Twistlock's documentation to obtain the correct chart name and version you wish to install. For this example, I'll assume we're deploying a hypothetical twistlock-defender chart from a given repository. We will use Pulumi's Kubernetes Chart resource, which is part of the Pulumi Kubernetes provider, to deploy a Helm Chart into a Kubernetes/OpenShift cluster.

    The Chart resource allows you to specify the chart name, version, and any custom values you want to override within the chart's values.yaml file.

    Here's a simple Pulumi program in TypeScript that would deploy the Twistlock Defender Helm Chart to your OpenShift cluster. The program assumes you've already configured access to your OpenShift cluster using kubectl.

    import * as k8s from "@pulumi/kubernetes"; // Define the Twistlock Defender Helm Chart. const twistlockDefenderChart = new k8s.helm.v3.Chart("twistlock-defender", { // Replace with the specific chart and version you want to deploy. chart: "twistlock-defender", version: "1.2.3", // specify the version of the chart fetchOpts:{ repo: "https://charts.example.com/", // specify the repo where the chart can be found }, // Specify the namespace where the chart should be deployed. // If you don't specify one, it will be deployed in the 'default' namespace. namespace: "twistlock", // Here you can also specify the values according to your need which will override the default values // of the Chart's `values.yaml` file. // For example: values: { // These key-value pairs should match the structure expected by the chart's `values.yaml` file. replicaCount: 2, // add more configuration based on your requirements }, }); // Export the name of the chart. export const chartName = twistlockDefenderChart.metadata.name;

    In the above program:

    • We start by importing the necessary Pulumi Kubernetes module to interact with our Kubernetes/OpenShift resources.
    • We then create a new instance of Chart called twistlockDefenderChart, which refers to the Twistlock Defender Helm chart.
    • The chart field specifies the name of the chart we want to deploy.
    • The version field is where you set the specific chart version you are deploying.
    • The repo inside fetchOpts field holds the URL of the repository where the Helm chart is hosted.
    • In the namespace field, we indicate that the chart should be deployed in the twistlock namespace. You should change this to whichever namespace you want to use, or create it if it doesn't exist already.
    • The values argument allows us to customize the chart configuratation by overriding default settings with our own values. These should align with what's available or required by the Twistlock Defender chart.

    Remember to check the actual chart documentation for the exact configuration parameters you can set via the values field. The replicaCount and additional configuration comments are only placeholders for actual values that you may want to adjust based on your environment and the Twistlock Defender Helm chart documentation.

    After the Pulumi program is set, run pulumi up to deploy it to your OpenShift cluster. The program will communicate with your cluster via kubectl, so ensure your kubectl is set up correctly to point to your OpenShift cluster.

    Keep in mind that managing your Pulumi stack, including the initial setup and deployment, typically requires familiarity with Pulumi concepts and CLI commands. If you're new to Pulumi, it's a good idea to walkthrough the Getting Started guide and understand the basics of creating projects, stacks, deploying resources, and managing state.
