Deploy the verzoekregistratiecomponent helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the "verzoekregistratiecomponent" Helm chart on Azure Managed OpenShift Service using Pulumi, you need to follow these steps:

Set up AZURE Managed OpenShift Cluster: You'll need an OpenShift cluster running in Microsoft Azure. Pulumi enables you to create a new OpenShift cluster using the azure-native.containerservice.OpenShiftManagedCluster resource. You'd define the resource with necessary properties like the location, resource group, and other configurations like network profile and agent pool profiles.
Deploy the Helm chart: Once you have an OpenShift cluster, you'll use the kubernetes.helm.v3.Chart resource from the Kubernetes package to deploy your Helm chart. This resource is a representation of a Helm chart in Pulumi's infrastructure as code paradigm.

Below is a basic program written in TypeScript, detailing each step including creating an OpenShift cluster and then deploying a Helm chart to it. This assumes that you have already configured kubectl with the cluster's access credentials and that you have the Pulumi CLI and npm modules installed.

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

// Step 1. Set up the Azure Managed OpenShift Cluster.
// Define a new OpenShift Managed Cluster
const openShiftCluster = new azure_native.containerservice.OpenShiftManagedCluster("openShiftManagedCluster", {
    // Replace these with the appropriate values for your setup.
    resourceGroupName: "<RESOURCE_GROUP_NAME>",
    resourceName: "<CLUSTER_NAME>",
    location: "westus", // Choose the right Azure region here.
    openShiftVersion: "4.3", // Specify your desired OpenShift version.
    
    // Define your network profile according to your organization's requirements.
    networkProfile: {
        vnetCidr: "10.0.0.0/8"
    },
    
    // Define your agent pool profile (nodes).
    agentPoolProfiles: [{
        name: "agentpool",
        count: 3,
        vmSize: "Standard_DS3_v2", // Choose the VM size that fits your needs.
    }],
    
    // Specify master pool profile as needed.
    masterPoolProfile: {
        count: 3,
        vmSize: "Standard_DS3_v2", // Ensure consistency in VM size or adjust as needed.
    } 
});

// Step 2. Deploy the Helm Chart to the Azure Managed OpenShift Cluster
// Create the Helm chart resource after the cluster is available.

// Provide the required kubeconfig from the OpenShift cluster
const kubeconfig = openShiftCluster.kubeconfig.apply(cfg =>
    pulumi.secret(JSON.stringify(cfg))
);

// Initialize the Kubernetes provider using the above kubeconfig
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: kubeconfig
});

// Deploy the Helm chart.
const chart = new k8s.helm.v3.Chart("verzoekregistratiecomponent", {
    chart: "verzoekregistratiecomponent",
    // Add chart version, repository, and namespace as needed.
    // For example, if the chart is hosted on a custom Helm repo:
    // version: "1.2.3",
    // repo: "https://my-helm-repo/",
    // namespace: "my-namespace",
}, { provider: k8sProvider });

// Export the URL to access the deployed Helm chart's service
// This part may vary based on the actual Helm chart you are installing.
export const serviceUrl = chart.getResourceProperty("v1/Service", "<RESOURCE_NAME>", "status").apply(status => status.loadBalancer.ingress[0].ip);

Please replace "<RESOURCE_GROUP_NAME>", "<CLUSTER_NAME>", and "my-namespace" with real values according to your Azure and Kubernetes setup.

This program does the following:

Initializes the creation of an Azure Managed OpenShift Cluster.
Waits for that cluster to become available and fetches its kubeconfig, which is needed to interact with the cluster via kubectl.
Uses the obtained kubeconfig to configure a Kubernetes Pulumi Provider, which defines how Pulumi accesses the Kubernetes cluster.
Deploys the specified Helm chart to the OpenShift cluster using the kubernetes.helm.v3.Chart resource. Adjust the chart, version, repo, and namespace as needed to point to the Helm chart you wish to deploy.

Remember to run pulumi up to deploy this stack. The output would be the URL of the service, which you can use to access your deployed Helm chart service.

Important Notes:

The program includes the creation of a managed OpenShift cluster, but if you already have a cluster, you can omit this step and just ensure you configure the Kubernetes provider with the correct kubeconfig.
Adjust property values as per your exact requirements for network settings, VM sizes, and locations.
Replace <RESOURCE_NAME> with the actual resource name of the service that your Helm chart will expose. Depending on the Helm chart, you may have to navigate to the appropriate Kubernetes resource.

Before running pulumi up, you must have the Pulumi CLI installed and have logged in, and you must also be logged in to Azure CLI (az login) with sufficient permissions to deploy resources in your subscription.
