Deploy the debug-toolbox helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

In order to deploy the `debug-toolbox` Helm chart on Azure Kubernetes Service (AKS), we'll need to create a few resources:

1. **Azure Kubernetes Service (AKS) Cluster**: This is where your applications will be hosted.
2. **Helm Release**: This is a Helm deployment in your AKS cluster. In this case, you'll be deploying the `debug-toolbox` chart.

Here is the step-by-step guide to deploy the `debug-toolbox` Helm chart on AKS using Pulumi:

1. **Create an AKS Cluster**: We will define an AKS cluster using Pulumi's `azure-native.containerservice.KubernetesCluster` resource.

2. **Install the Helm Chart**: After creating the AKS cluster, we will use Pulumi's `kubernetes.helm.v3.Chart` resource to install the `debug-toolbox` chart on that cluster.

Now, let's move on to the actual Pulumi TypeScript program to accomplish this:

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

// Step 1: Create an AKS cluster
const cluster = new azure.containerservice.KubernetesCluster("myAksCluster", {
    // Replace these with appropriate values or dynamically generate them
    resourceGroupName: "myResourceGroup",
    location: "WestUS",
    agentPoolProfiles: [{
        name: "agentpool",
        count: 1,
        vmSize: "Standard_DS2_v2",
    }],
    dnsPrefix: "myk8scluster",
});

// Export the KubeConfig
export const kubeConfig = cluster.kubeConfig;

// Step 2: Deploy the `debug-toolbox` Helm chart into AKS cluster
import * as k8s from "@pulumi/kubernetes";

// Using the generated KubeConfig from the AKS cluster to connect to the Kubernetes cluster
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: kubeConfig.apply(JSON.stringify),
});

// Deploys the debug-toolbox Helm chart using the kubeconfig
const debugToolboxChart = new k8s.helm.v3.Chart("debug-toolbox", {
    chart: "debug-toolbox",
    // Specify the Helm repository that contains the chart
    fetchOpts: {
        repo: "https://example.com/helm-charts", // Replace with the actual Helm repo URL containing `debug-toolbox`
    },
}, { provider: k8sProvider });

// Export the Helm chart name and version
export const chartName = debugToolboxChart.chart;
export const chartVersion = debugToolboxChart.version;
```

In this program:

- We create an AKS cluster with the `azure-native.containerservice.KubernetesCluster` resource.
- We export `kubeConfig` of the AKS cluster to be used to communicate with the Kubernetes cluster.
- We define a new instance of the Pulumi Kubernetes Provider (`k8s.Provider`) that uses the kubeconfig of the AKS cluster.
- We deploy the `debug-toolbox` Helm chart by creating an instance of `k8s.helm.v3.Chart`.

Make sure to replace placeholder values (e.g., the resource group name, the location, and the Helm repository URL) with actual values that apply to your case.

To use this Pulumi program, save it in a file with a `.ts` extension, such as `aksDebugToolbox.ts`. Ensure you have Pulumi CLI installed and configured for use with Azure. Use `npm` to install Pulumi's Kubernetes and Azure plugins if you haven't already:

```bash
npm install @pulumi/pulumi @pulumi/kubernetes @pulumi/azure-native
```

Then, you can run the program with the Pulumi CLI:

```bash
pulumi up
```

Pulumi will prompt you to review the changes and proceed with the deployment. After the deployment, it will output any exported values, such as the kubeconfig.
