1. Deploy the zookeeper-3Nodes helm chart on Azure Managed Openshift Service

    TypeScript

    To deploy the zookeeper-3Nodes Helm chart on Azure Managed OpenShift Service using Pulumi, we'll proceed in two main steps:

    1. Provision an Azure Red Hat OpenShift (ARO) Cluster: We will create a managed OpenShift cluster on Azure, which provides a Kubernetes-conformant platform supported by Microsoft and Red Hat.

    2. Deploy the Helm Chart on the ARO Cluster: Once we have the OpenShift cluster ready, we will deploy the zookeeper-3Nodes Helm chart to this cluster.

    We'll write a TypeScript program using Pulumi to accomplish both tasks.

    Here's a step-by-step breakdown of what we're going to code:

    • Import the necessary Pulumi packages.
    • Set up an Azure Red Hat OpenShift cluster using azure-native.redhatopenshift.OpenShiftCluster resource.
    • Deploy the Helm chart to the OpenShift cluster using kubernetes.helm.v3.Chart resource.

    Before you run this code, ensure you have the following prerequisites completed:

    • Install Pulumi CLI and set up Azure credentials.
    • Install Node.js and npm to run the Pulumi TypeScript program.
    • Create a new Pulumi project or use an existing one.

    Below is the full Pulumi TypeScript program that accomplishes these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Set up an Azure Red Hat OpenShift (ARO) Cluster const resourceGroupName = new azure_native.resources.ResourceGroup("myResourceGroup", { resourceGroupName: "myResourceGroup", location: "eastus", }); const openShiftCluster = new azure_native.redhatopenshift.OpenShiftCluster("myOpenShiftCluster", { resourceGroupName: resourceGroupName.name, resourceName: "myOpenShiftCluster", location: resourceGroupName.location, clusterProfile: { pullSecret: "<pull-secret>", // Replace with your pull secret from Red Hat OpenShift domain: "example.com", // Replace with your domain version: "4.6", // Specify the version of OpenShift }, masterProfile: { vmSize: "Standard_D8s_v3", }, networkProfile: { podCidr: "10.128.0.0/14", serviceCidr: "172.30.0.0/16", }, workerProfiles: [{ name: "worker", // Define your worker nodes' details vmSize: "Standard_D4s_v3", diskSizeGB: 128, subnetId: "/subscriptions/<subscription-id>/resourceGroups/<vnet-resource-group>/providers/Microsoft.Network/virtualNetworks/<vnet-name>/subnets/<worker-subnet-name>", // Provide Subnet ID for worker nodes count: 3, // Number of worker nodes, you can adjust this as necessary }], servicePrincipalProfile: { clientId: "<client-id>", // Azure service principal ID clientSecret: "<client-secret>", // Azure service principal secret }, }, { dependsOn: [resourceGroupName] }); // Deploy the zookeeper-3Nodes Helm chart on Azure Managed OpenShift Service const k8sProvider = new k8s.Provider("myK8sProvider", { kubeconfig: pulumi.interpolate`${openShiftCluster.kubeadminKubeconfig}`, // This uses the kubeconfig output from the cluster }); const zookeeperHelmChart = new k8s.helm.v3.Chart("zookeeper-3nodes", { chart: "zookeeper", version: "5.23.0", // Use the specific chart version you need for zookeeper fetchOpts: { repo: "https://charts.helm.sh/stable", }, values: { replicaCount: 3, // Set the number of Zookeeper nodes // You can set additional custom values for the chart here. }, }, { provider: k8sProvider }); // Export the OpenShift cluster's kubeconfig export const kubeconfig = openShiftCluster.kubeadminKubeconfig;

    Make sure to replace placeholders such as <pull-secret>, <subscription-id>, <vnet-resource-group>, and others with your own specific values.

    Explaining the Code:

    • We initialize the Pulumi Azure Native provider to work with Azure resources by creating a new resource group and an OpenShift cluster within that group.
    • With azure_native.redhatopenshift.OpenShiftCluster, we define the properties for our OpenShift cluster, like the pull secret, domain, version, and profile sizes for master and worker nodes.
    • After the OpenShift cluster is provisioned, we initialize a Pulumi Kubernetes provider using k8s.Provider. This provider is configured with the kubeconfig from the OpenShift cluster, allowing Pulumi to interact with it as a Kubernetes cluster.
    • We deploy the zookeeper Helm chart using k8s.helm.v3.Chart, specifying the chart name, version, and default values needed.

    Running Your Code:

    1. Save this TypeScript code in a file named index.ts.
    2. Run pulumi up to preview and deploy the changes.
    3. Upon successful deployment, Pulumi will print the exported kubeconfig output, which you can use to connect to your OpenShift cluster.
