Deploy the nirmata-kyverno-operator helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the Nirmata Kyverno Operator Helm Chart on an Azure Managed OpenShift Service using Pulumi, you will need to perform the following tasks:

Create a new Azure Resource Group if you don't have one already.
Provision an Azure Red Hat OpenShift Cluster within the resource group.
Once the cluster is provisioned, configure Pulumi to use the cluster's credentials to communicate with the Kubernetes API.
Deploy the Nirmata Kyverno Operator Helm Chart into the OpenShift Cluster.

First, make sure that you have Pulumi and the Azure CLI installed and have authenticated with Azure using az login. You should also have access to the OpenShift cluster's kubeconfig after it has been set up.

Here is the TypeScript program for Pulumi that depicts the above steps:

import * as pulumi from '@pulumi/pulumi';
import * as azureNative from '@pulumi/azure-native';
import * as k8s from '@pulumi/kubernetes';

// Step 1: Create a new Azure Resource Group
const resourceGroup = new azureNative.resources.ResourceGroup("myResourceGroup");

// Step 2: Provision an Azure Red Hat OpenShift Cluster
const openshiftCluster = new azureNative.redhatopenshift.OpenShiftCluster("myOpenShiftCluster", {
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    clusterProfile: {
        pullSecret: "<your-pull-secret>",  // Replace with your pull secret
        domain: "example",  // Replace with your domain
        version: "4.3.0",  // Specify the OCP version
    },
    masterProfile: {
        vmSize: "Standard_D8s_v3", // Specify the VM size
    },
    networkProfile: {
        podCidr: "10.128.0.0/14",
        serviceCidr: "172.30.0.0/16",
    },
    // Specify other required fields as necessary
});

// The provider needs to be configured with the appropriate kubeconfig
const openshiftProvider = new k8s.Provider("openshiftK8s", {
    kubeconfig: "<kubeconfig>", // Replace with your kubeconfig data
});

// Step 3: Deploy the Nirmata Kyverno Operator Helm Chart
const kyvernoChart = new k8s.helm.v3.Chart("nirmata-kyverno-operator", {
    chart: "kyverno",
    version: "1.3.0", // Replace with the specific chart version you want
    fetchOpts: {
        repo: "https://nirmata.github.io/kyverno/", // Helm repo URL for Nirmata's Kyverno
    },
}, { provider: openshiftProvider });

// Export the resource group name and the Kubernetes cluster name
export const resourceGroupName = resourceGroup.name;
export const openshiftClusterName = openshiftCluster.name;

In this Pulumi program:

We create a new Azure Resource Group using the ResourceGroup resource from the @pulumi/azure-native package.
An Azure Red Hat OpenShift Cluster is provisioned using the OpenShiftCluster resource. You'll need to replace placeholder values like <your-pull-secret> and example domain with actual values.
A K8s Provider is declared with the kubeconfig of the OpenShift cluster, which allows Pulumi to communicate with the Kubernetes API.
The Kyverno Helm Chart is deployed using Pulumi's Helm support through the Chart resource. This resource manages the Helm chart installation within the specified OpenShift cluster.

Make sure to replace <kubeconfig> with your cluster's kubeconfig data and update other placeholder values to reflect your environment and desired configuration.

To apply this Pulumi program, you would typically navigate to the directory containing your program and run pulumi up. This command will start the deployment process as defined. You will be prompted to review changes before they are applied, ensuring control over your infrastructure changes.
