Deploy the opencve helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the OpenCVE helm chart on Azure Managed Openshift Service, you'll need to set up the Azure Managed Openshift cluster, configure Kubernetes provider to interact with it, and then use the Helm Chart resource to deploy the chart. I'll walk you through the process step by step.

### Prerequisites

Before proceeding, make sure that:

1. You have an Azure account with the necessary permissions to create resources.
2. You've installed the Pulumi CLI and set up your Pulumi account.
3. You've [installed the Azure CLI](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli) and logged in to your Azure account using `az login`.

### Step 1: Setting up Azure Managed Openshift Service

To create the Managed Openshift cluster using Pulumi, you’ll use the `azure-native.containerservice.OpenShiftManagedCluster` resource.

### Step 2: Configuring Kubernetes Provider

Once the Openshift cluster is ready, you'll configure the Pulumi Kubernetes provider to interact with the cluster using the kubeconfig from the OpenShift cluster resource output.

### Step 3: Deploying the OpenCVE Helm Chart

For deploying the Helm chart, you'll use `kubernetes.helm.v3.Chart` - a Pulumi resource which allows you to specify Helm charts directly in your Pulumi program.

Below is a Pulumi program written in TypeScript that creates these resources. The program assumes the required Azure and Kubernetes configurations are set.

```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 openshiftCluster = new azureNative.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", {
    // Replace these with appropriate values
    resourceGroupName: "myResourceGroup",
    resourceName: "myClusterName",
    location: "eastus",
    openShiftVersion: "4.3", // Specify the version
    // Define the cluster and agent pool profiles, network profile etc. as per your requirements
    masterPoolProfile: {
        // ...
    },
    agentPoolProfiles: [
        // ...
    ],
    // You may need to provide additional configurations such as network profile, identity providers, etc.
});

// Step 2: Configure Kubernetes provider to communicate with the new Openshift cluster
const kubeconfig = pulumi.all([openshiftCluster.name, openshiftCluster.resourceGroupName]).apply(([name, rg]) => {
    // Here you would acquire the kubeconfig file from Azure
    // This is a simplification; in practice you would use the Azure CLI or SDK to get this information securely
    const acquiredKubeConfig = ""; // Replace with actual kubeconfig acquisition logic
    return acquiredKubeConfig;
});

const k8sProvider = new k8s.Provider("myK8sProvider", {
    kubeconfig: kubeconfig,
});

// Step 3: Deploy the OpenCVE Helm Chart
const openCveChart = new k8s.helm.v3.Chart("opencve", {
    chart: "opencve",
    version: "1.2.3", // Replace with the actual chart version you intend to deploy
    fetchOpts: {
        repo: "http://myhelmrepo/", // Replace with the actual Helm repository URL
    },
}, { provider: k8sProvider });

// Export the cluster's kubeconfig and OpenCVE service endpoint
export const kubeConfig = kubeconfig;
export const openCveServiceIp = openCveChart.getResourceProperty("v1/Service", "opencve-svc", "status").apply(status => status.loadBalancer.ingress[0].ip);
```

### Explanation

1. The `azure-native.containerservice.OpenShiftManagedCluster` resource is responsible for creating a cluster on Azure. You must provide specific configurations such as the resource group, location, Openshift version, master, and agent profiles.

2. After the cluster is created, you obtain the `kubeconfig` needed to interact with the Openshift cluster programmatically. Normally, you would use the Azure CLI or SDK to retrieve the kubeconfig.

3. With kubeconfig in hand, a Kubernetes provider instance is created. This provider will be used to interact with the Kubernetes API on your Openshift cluster.

4. Finally, the `kubernetes.helm.v3.Chart` resource installs the OpenCVE chart from the specified Helm repository. You must specify the chart name, version, and repository details.

The `kubeConfig` and the IP address for the deployed OpenCVE service are exported so that you can use them to interact with your cluster and OpenCVE installation.

After setting up this Pulumi program, you can run `pulumi up` in your CLI to provision these resources. Make sure to replace placeholders with actual values where necessary, especially the kubeconfig retrieval logic which is beyond the scope of this example.
