Deploy the ibm-cp4s-threatmgmt-instance helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

Deploying the IBM Cloud Pak for Security (CP4S) Threat Management instance using a Helm chart on an Azure Red Hat OpenShift (ARO) cluster involves several steps. First, we will provision an ARO cluster, then we'll use the Helm package manager to deploy CP4S. We will use Pulumi to automate this process.

Here's a high-level overview of the steps we will follow in the code:
1. Set up a new Azure Red Hat OpenShift cluster.
2. Install the Helm chart for IBM CP4S Threat Management on the OpenShift cluster.

To accomplish this, we will utilize the `azure-native` provider for creating the OpenShift cluster and the `kubernetes` provider for deploying the Helm chart.

First, make sure you have Pulumi installed and configured for your Azure account. You will need to authenticate with Azure and set the correct context for OpenShift cluster operations.

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

// Create an Azure Resource Group
const resourceGroup = new azure.containerservice.OpenShiftManagedCluster("resourceGroup", {
    // Provide your resource group's location and name
    resourceGroupName: "myResourceGroup",
    location: "East US",
    // Define other necessary properties for the cluster here, such as network profile and authentication profile.
});

// Once the OpenShift cluster is up and running, we will retrieve its Kubeconfig.
const clusterKubeconfig = resourceGroup.kubeConfig;

// We use the kubeconfig for connecting to Kubernetes Cluster and deploy the helm chart.
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: clusterKubeconfig,
});

// Define the Helm chart for IBM CP4S Threat Management
const ibmCp4sHelmChart = new k8s.helm.v3.Chart("ibmCp4sChart", {
    // Specify the chart, version, and any values to override.
    chart: "ibm-cp4s-threatmgmt-instance",
    repositoryOpts: {
        repo: "https://example.com/helm-charts", // Replace with the correct IBM CP4S Helm chart repository
    },
    values: {
        // Provide configuration parameters required for the IBM CP4S Threat Management Helm chart.
    },
}, { provider: k8sProvider });

// Export the endpoint of IBM CP4S Threat Management
export const cp4sEndpoint = pulumi.interpolate`${ibmCp4sHelmChart.status}`;
```

In the above program:

- We first create a new Azure Red Hat OpenShift cluster using the `azure-native.containerservice.OpenShiftManagedCluster` resource. Here, you need to provide the desired location along with other properties such as network and authentication profiles.
- Next, we obtain the Kubeconfig of our OpenShift cluster which is necessary for Kubernetes authentication.
- We then initialize a Pulumi Kubernetes provider `k8s.Provider` with the retrieved Kubeconfig. This provider will manage our Kubernetes resources.
- After establishing a connection to the newly created cluster, we proceed to deploy the IBM CP4S Threat Management Helm chart using the Pulumi Kubernetes `k8s.helm.v3.Chart` resource.
- Lastly, we export the endpoint where IBM CP4S Threat Management will be accessible once deployed.

Please ensure to replace `"https://example.com/helm-charts"` with the actual Helm chart repository URL of IBM CP4S Threat Management. You may also need to specify additional configurations in `values` based on the prerequisites of the Helm chart.

To run this Pulumi program, save it as `index.ts` in a new directory, initialize a Pulumi project with `pulumi new`, and then execute `pulumi up`. If this is your first time using Pulumi, you can refer to the [Pulumi Get Started](https://www.pulumi.com/docs/get-started/) guide for detailed instructions.
