Deploy the http-debug helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the `http-debug` Helm chart on Azure Managed OpenShift Service, you'll need to follow these steps:

1. **Create an OpenShift Managed Cluster:** Utilize the `azure-native.containerservice.OpenShiftManagedCluster` resource to create an OpenShift cluster in Azure.

2. **Set up a K8s Provider for Pulumi to Interact with OpenShift:** Configure a Kubernetes provider that Pulumi will use to interact with the newly created OpenShift cluster.

3. **Deploy the Helm Chart:** Use the `kubernetes.helm.v3.Chart` resource to deploy the `http-debug` Helm chart onto your OpenShift cluster.

Below is a TypeScript program that demonstrates how to perform each of these steps using Pulumi.

Ensure you have Pulumi CLI installed and configured with your Azure account. Also, `kubectl` should be installed and configured to interact with Kubernetes clusters.

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

// Step 1: Create an Azure Managed OpenShift cluster
const cluster = new azureNative.containerservice.OpenShiftManagedCluster("myManagedCluster", {
    resourceGroupName: "myResourceGroup", // Replace with your resource group name
    location: "East US", // Replace with the desired location
    openShiftVersion: "4.3", // Specify your OpenShift version
    // Define the properties of the managed cluster, such as network profiles, tags, etc.
    // More properties are available and should be set according to your specific requirements.
});

// Step 2: Set up a Kubernetes provider using the kubeconfig of the created OpenShift cluster
const myK8sProvider = new k8s.Provider("myK8sProvider", {
    kubeconfig: cluster.kubeconfig.apply(kubeconfig => kubeconfig), // Extract kubeconfig from the created OpenShift cluster
});

// Step 3: Deploy the `http-debug` Helm chart onto the OpenShift cluster
const httpDebugChart = new k8s.helm.v3.Chart("httpDebugChart", {
    chart: "http-debug", // The name of the Helm chart you want to deploy
    // Note: You must specify the repository where the chart is located using the `repo` argument or add it to your Helm repositories.
    namespace: "default", // Specify the namespace where you want the chart to be deployed
}, { provider: myK8sProvider });

// Export the OpenShift cluster's kubeconfig and the Helm chart deployment status
export const kubeconfig = cluster.kubeconfig;
export const deployedChartStatus = httpDebugChart.status;
```

Here's a breakdown of what the program does:

- First, we create an instance of an OpenShift Managed Cluster in the specified resource group and location. The `openShiftVersion` must be set according to the supported versions available in Azure Managed OpenShift.
  
- Next, we configure a Kubernetes provider using the `kubeconfig` obtained from the newly created cluster. This `kubeconfig` is necessary for Pulumi to manage resources in the OpenShift cluster.

- Finally, we deploy the `http-debug` Helm chart using Pulumi's Helm Chart resource. You'll need to replace `'http-debug'` with the correct Helm chart name and may need to specify the `repo` containing the `http-debug` chart if it's not located in the standard Helm chart repositories.

Once this Pulumi program is run, an OpenShift cluster will be created, and the `http-debug` chart will be deployed to the `default` namespace of the cluster. If you need it to be installed in a different namespace, specify the desired namespace in the `namespace` property.
