Deploy the paypal-sandbox-dashboard helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

To deploy a Helm chart on an Azure Kubernetes Service (AKS) cluster, you need to complete several steps:

1. Set up an AKS cluster.
2. Ensure you have Helm installed and configured to work with your Kubernetes cluster.
3. Use the Helm Pulumi provider to deploy your chart to the cluster.

We will use Pulumi with TypeScript for this process. Pulumi allows us to define our infrastructure as code, and the Pulumi Kubernetes provider gives us the ability to manage Kubernetes resources including deploying Helm charts.

Below is a Pulumi program that:
- Creates an AKS cluster.
- Configures the Kubernetes provider to deploy Helm charts to the created AKS cluster.
- Uses the Helm Chart resource from the Pulumi Kubernetes provider to deploy the `paypal-sandbox-dashboard` helm chart.

Make sure you have Azure CLI installed and configured and you are logged in to your Azure account with `az login`. Also, ensure you have Pulumi CLI installed.

Here is the TypeScript program for deploying the PayPal Sandbox Dashboard Helm chart to AKS:

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

// Step 1: Create an Azure Kubernetes Service (AKS) cluster
const resourceGroup = new azure.core.ResourceGroup("aksResourceGroup", {
    location: "East US", // Azure region for the resource group and the cluster
});

const aksCluster = new azure.containerservice.KubernetesCluster("aksCluster", {
    resourceGroupName: resourceGroup.name,
    agentPoolProfiles: [{
        count: 2, // Number of nodes in the node pool
        vmSize: "Standard_DS2_v2", // Size of the virtual machines in the node pool
    }],
    dnsPrefix: "aks-cluster", // DNS prefix for the AKS cluster
    linuxProfile: {
        adminUsername: "aksuser",
        sshKey: {
            keyData: "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD3dJ..." // Replace with your public SSH key
        }
    },
    servicePrincipal: {
        clientId: process.env.AZURE_CLIENT_ID, // Replace with your Azure Client ID
        clientSecret: process.env.AZURE_CLIENT_SECRET, // Replace with your Azure Client Secret
    }
});

// Export the Kubeconfig of the AKS cluster which will be used to configure the Kubernetes provider
export const kubeconfig = aksCluster.kubeConfigRaw;

// Step 2: Configure Kubernetes provider to deploy Helm charts to the AKS cluster
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: kubeconfig,
});

// Step 3: Deploy the paypal-sandbox-dashboard Helm chart to the AKS cluster
const paypalSandboxDashboardChart = new k8s.helm.v3.Chart("paypal-sandbox-dashboard", {
    chart: "paypal-sandbox-dashboard",
    version: "1.0.0", // Use the appropriate version for the chart
    fetchOpts: {
        repo: "http://your-helm-chart-repository/", // Replace with your Helm chart repository URL
    },
}, { provider: k8sProvider });

// Export the URL to access the PayPal Sandbox Dashboard
export const paypalSandboxDashboardUrl = pulumi.interpolate`http://${aksCluster.name}.eastus.cloudapp.azure.com`;
```

Before running `pulumi up`, make sure to replace:

- `"ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD3dJ..."` with your actual public SSH key.
- `AZURE_CLIENT_ID` and `AZURE_CLIENT_SECRET` with your actual Azure client ID and client secret.
- `1.0.0` with the version of the Helm chart you wish to deploy.
- `http://your-helm-chart-repository/` with the URL of your Helm chart repository.

This program creates a new AKS cluster and deploys the `paypal-sandbox-dashboard` Helm chart to it. The `kubeConfigRaw` output of the `aksCluster` is used to provision the Kubernetes provider, which allows Pulumi to interact with the AKS cluster.

Once the Pulumi program is executed with `pulumi up`, it provisions the AKS cluster and deploys the Helm chart. After completion, Pulumi will output the URL under `paypalSandboxDashboardUrl`, which you can use to access the PayPal Sandbox Dashboard.

Remember to check the official Pulumi documentation for [AKS](https://www.pulumi.com/docs/reference/pkg/azure/containerservice/kubernetescluster/) and [Helm charts](https://www.pulumi.com/docs/reference/pkg/kubernetes/helm/v3/chart/) if you need more details or wish to customize this template further.
