Deploy the ibm-unified-console helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

To deploy the `ibm-unified-console` Helm chart on Azure Kubernetes Service (AKS) using Pulumi, you would typically follow these high-level steps:

1. **Set up an Azure Kubernetes Service (AKS) cluster**: Before deploying any Helm charts, you need a running Kubernetes cluster. AKS is a managed container orchestration service provided by Azure that simplifies the deployment, management, and operations of Kubernetes clusters.

2. **Install and Configure Kubectl**: `kubectl` is the Kubernetes command-line tool that allows you to run commands against Kubernetes clusters. You need to install and configure it to communicate with your AKS cluster to deploy Helm charts.

3. **Set up Helm**: Helm is a package manager for Kubernetes that allows you to define, install, and upgrade even the most complex Kubernetes applications. Helm charts help define, install, and upgrade the Kubernetes application.

4. **Deploy the Helm Chart**: With your AKS cluster running and `kubectl` and Helm set up, you can now deploy the `ibm-unified-console` chart to your cluster.

Here is the TypeScript program using Pulumi to set up an AKS cluster and deploy the `ibm-unified-console` Helm chart:

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

// Create an Azure Resource Group
const resourceGroup = new azure.core.ResourceGroup("resourceGroup", {
    location: "East US", // You can choose a different location
});

// Create an AKS cluster
const cluster = new azure.containerservice.KubernetesCluster("aksCluster", {
    resourceGroupName: resourceGroup.name,
    defaultNodePool: {
        vmSize: "Standard_DS2_v2", // This is a general-purpose VM size. You can change it depending on your needs.
        minCount: 1,
        maxCount: 3, // Configure auto-scaling for your node pool
        enableAutoScaling: true,
    },
    dnsPrefix: "aksClusterDns", // Replace with a unique DNS prefix
    servicePrincipal: {
        clientId: "", // Add your service principal credentials
        clientSecret: "", 
    },
});

// Export the Kubeconfig
export const kubeconfig = cluster.kubeConfigRaw;

// Use the Pulumi Kubernetes provider to interact with the AKS cluster
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: cluster.kubeConfigRaw,
});

// Deploy the ibm-unified-console Helm chart
const ibmUnifiedConsoleChart = new k8s.helm.v3.Chart("ibm-unified-console", {
    chart: "ibm-unified-console",
    // Specify the Helm repository here
    // fetchOpts: {
    //   repo: "https://charts.example.com/",
    // },
    // version: "x.y.z", // Specify the chart version
    // values: {} // If needed, you can configure the chart values here
}, { provider: k8sProvider });

```

This program performs the following actions:

- Import the necessary Pulumi SDKs for use in the program.
- Create an Azure resource group to contain all the resources.
- Provision a new AKS cluster within the resource group with an auto-scaling node pool and specified DNS prefix. You would need to replace the `clientId` and `clientSecret` with valid Azure service principal credentials.
- Export the kubeconfig of the cluster which is required to interact with the cluster using `kubectl`.
- Set up the Kubernetes provider that points to the newly created AKS cluster.
- Define and deploy the `ibm-unified-console` Helm chart using the Kubernetes provider.

To successfully run this program, replace the placeholders (like the service principal credentials) with actual values from your Azure environment. Ensure that your Pulumi stack is correctly configured to use Azure credentials.

The `ibm-unified-console` Helm chart details such as repository URL and version are placeholders; you'll need to replace them with the actual values from where the chart is hosted.

After writing this code to a file (such as `index.ts`), you would run it using the Pulumi CLI commands `pulumi up` to create and deploy the resources. Ensure you have Pulumi and the required plugins installed on your machine.
