1. Deploy the kyverno-stub-crds helm chart on Opensshift


    To deploy the kyverno-stub-crds Helm chart on an OpenShift cluster using Pulumi, you will be utilizing the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. This resource allows you to deploy Helm charts into a Kubernetes cluster in a declarative way with Pulumi.

    The kubernetes.helm.v3.Chart resource takes several inputs, including the chart name, the repository where the chart is located (if it's not a locally available chart), and any custom values you wish to provide to configure the Helm chart.

    Below is a Pulumi program written in TypeScript that demonstrates how to deploy the kyverno-stub-crds Helm chart on OpenShift. This example assumes that you have already set up an OpenShift cluster and have configured Pulumi to use the appropriate Kubernetes context to communicate with it.

    Before running this Pulumi program, ensure you have the following prerequisites:

    • Pulumi CLI installed and authenticated to your OpenShift cluster.
    • Helm CLI installed, if you need to fetch chart dependencies or manage Helm repositories.
    • A kubeconfig file configured with access to your OpenShift cluster.

    Now, let’s look at the Pulumi program:

    import * as k8s from "@pulumi/kubernetes"; // Create an instance of the helm.v3.Chart class to deploy the kyverno-stub-crds Helm chart. const kyvernoStubCRDsChart = new k8s.helm.v3.Chart("kyverno-stub-crds", { // Define the repository options. Replace `CHART_REPO_URL` with the actual URL of the repository. repo: "CHART_REPO_URL", // Example: "https://kyverno.github.io/kyverno/" chart: "kyverno-stub-crds", // Specify the chart version you want to deploy. If omitted, the latest version will be deployed. version: "CHART_VERSION", // Replace with the specific chart version, for example, "1.3.4". // Provide any custom values you want to specify for the chart configuration. values: { // Custom values for the chart can be specified here as key-value pairs. // Example: // replicaCount: 3, // This would be specific to the Helm chart you're using. }, // If the helm chart requires a specific namespace, provide it here. namespace: "kyverno" // Replace with the namespace you wish to deploy the CRDs to. }, { // If you need any specific transformations or custom logic to process the generated YAML manifests // before they are applied to the cluster, you can specify them here. }); // To access your deployed resources, you can use stack outputs. // This example assumes you might want to get the name of the deployed Helm release. export const releaseName = kyvernoStubCRDsChart.getResourceProperty("v1/Service", "kyverno-service", "metadata.name");

    Replace CHART_REPO_URL with the actual repository URL where the kyverno-stub-crds Helm chart is hosted and CHART_VERSION with the specific version of the chart you want to deploy. If you don't have this information, you might need to search for the maintained Helm chart for Kyverno or visit their official charts repository.

    In the values field, you'll typically set configuration parameters that the kyverno-stub-crds chart supports. These parameters allow you to customize how the CRDs are deployed on your cluster. If the Helm chart doesn't require any special configuration, you may omit this field or leave it empty.

    After writing and saving your Pulumi program, perform the following steps in the command line to deploy the Helm chart:

    1. Change to the directory containing the Pulumi code.
    2. Run pulumi up to preview and deploy the changes.

    Please check the Pulumi Kubernetes documentation for more details on deploying Helm charts with Pulumi.
