Deploy the testkube-dashboard helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the `testkube-dashboard` Helm chart on an Azure Managed OpenShift service using Pulumi, you will need to take the following high-level steps:

1. **Set up an Azure Managed OpenShift Cluster**: You need to have an OpenShift cluster running in Azure to be able to install Helm charts. This requires setting up networking resources like Virtual Network and Subnet, and then deploying the OpenShift cluster into this network.
2. **Install the Helm Chart**: Once the cluster is up and running, you can use Pulumi's Kubernetes provider to install the `testkube-dashboard` Helm chart on the OpenShift cluster.

Below, you will find a Pulumi TypeScript program that includes these steps:

- We'll use the `azure-native` package to create a Managed OpenShift Cluster.
- Then, we'll create a Kubernetes provider instance that targets the newly created OpenShift cluster.
- Using the Kubernetes provider, we'll deploy the `testkube-dashboard` Helm chart.

```typescript
import * as azure from "@pulumi/azure-native";
import * as pulumi from "@pulumi/pulumi";
import * as k8s from "@pulumi/kubernetes";

// Step 1: Create the Managed OpenShift cluster in Azure
// Note: Replace the values in `resourceGroupName` and `openshiftClusterName` with your own.

const resourceGroupName = "myResourceGroup";
const openshiftClusterName = "myOpenShiftCluster";

// Create an Azure resource group
const resourceGroup = new azure.resources.ResourceGroup(resourceGroupName);

// Create a virtual network and a subnet where the OpenShift cluster will be deployed
const vnet = new azure.network.VirtualNetwork("myVnet", {
    resourceGroupName: resourceGroup.name,
    addressSpace: {
        addressPrefixes: ["10.0.0.0/16"],
    },
});

const subnet = new azure.network.Subnet("mySubnet", {
    resourceGroupName: resourceGroup.name,
    addressPrefix: "10.0.0.0/24",
    virtualNetworkName: vnet.name,
});

// Deploy the Azure Managed OpenShift Cluster
const openshiftCluster = new azure.containerservice.OpenShiftManagedCluster(openshiftClusterName, {
    resourceGroupName: resourceGroup.name,
    // Additional required properties will need to be added here
});

// Step 2: Deploy the `testkube-dashboard` Helm chart on the OpenShift cluster

// Extract the kubeconfig of the OpenShift cluster
const kubeconfig = pulumi
    .all([openshiftCluster.name, resourceGroup.name])
    .apply(([clusterName, resourceGroupName]) => {
        // Replace with the appropriate method to fetch your kubeconfig
        return azure.containerservice.listOpenShiftManagedClusterAdminCredentials({
            resourceName: clusterName,
            resourceGroupName: resourceGroupName,
        }).clusterAdminKubeconfig;
    });

// Create a Kubernetes provider instance with the kubeconfig
const k8sProvider = new k8s.Provider("openshift-k8s-provider", {
    kubeconfig: kubeconfig,
});

// Deploy the `testkube-dashboard` Helm chart using the Kubernetes provider
const testkubeDashboard = new k8s.helm.v3.Chart(
    "testkube-dashboard",
    {
        repo: "testkube", // Replace with the appropriate Helm repo name
        chart: "testkube-dashboard",
        // Specify any custom values.yaml configuration here if necessary
    },
    { provider: k8sProvider }
);

// Export the OpenShift cluster API server URL and the Helm chart status
export const openshiftApiServerUrl = openshiftCluster.openShiftApiServerUrl;
export const testkubeDashboardStatus = testkubeDashboard.status;

```

Explanation:
- We start by declaring some constants for naming the resources.
- We create a new resource group and a virtual network with a subnet.
- We then provision a Managed OpenShift cluster on Azure.
- In the next step, we retrieve the `kubeconfig` from the created OpenShift cluster, which is needed for the Kubernetes provider to interact with the cluster.
- We create a Kubernetes provider with this `kubeconfig`.
- Finally, we deploy the `testkube-dashboard` Helm chart using the Kubernetes provider.

You would need to replace the placeholder values for the repository of the Helm chart (if different from the official Helm chart repository) and provide the actual name of the Helm chart for `testkube-dashboard`. You might also need to provide additional information like authentication details for connecting to Azure, or necessary configurations for the OpenShift Managed Cluster or the helm chart which depend on your specific use case.
