Deploy the projectsveltos helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

To deploy the `projectsveltos` Helm chart on Azure Kubernetes Service (AKS), you need to perform the following steps:

1. Create an AKS cluster or use an existing one where you want to deploy the Helm chart.
2. If you don't have a Helm chart called `projectsveltos`, you need to ensure it is available, either in a public Helm repository or a location you can access.
3. Install the Helm chart onto your AKS cluster.

Below is a step-by-step guide in TypeScript using Pulumi to automate these tasks. The program will:

- Provision an AKS cluster if you don't already have one.
- Leverage the Pulumi provider for Kubernetes to install the `projectsveltos` Helm chart.

Let's look at the complete Pulumi program to achieve this:

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

// Step 1: Create an AKS cluster
// Replace variables with your desired settings for the AKS cluster.
const resourceGroupName = new azure.core.ResourceGroup("aksResourceGroup", {
    location: "WestUS", // Set to your preferred Azure region.
});

const aksCluster = new azure.containerservice.KubernetesCluster("aksCluster", {
    resourceGroupName: resourceGroupName.name,
    defaultNodePool: {
        name: "default",
        nodeCount: 2,
        vmSize: "Standard_DS2_v2",
    },
    dnsPrefix: "aksk8s", // Replace with your own DNS prefix.
    identity: {
        type: "SystemAssigned",
    },
    location: resourceGroupName.location,
});

// Export the kubeconfig, which is required to interact with the AKS cluster.
export const kubeconfig = aksCluster.kubeConfigRaw;

// Step 2: Install the `projectsveltos` Helm chart on the AKS cluster
// The chart might need to be referenced from a specific Helm repository.
// For example, if it was available on a public repo, you would add that repo first with `helm repo add`.
// Here, we'll assume it is already available.
const projectsveltosHelm = new k8s.helm.v3.Chart("projectsveltos", {
    chart: "projectsveltos",
    version: "0.1.0", // Use the correct version.
    namespace: "default", // You can specify the namespace or change it.
}, {
    provider: new k8s.Provider("k8sProvider", {
        kubeconfig: aksCluster.kubeConfigRaw,
    }),
});

// Export the status of the Helm release
export const helmStatus = projectsveltosHelm.status;
```

Explanation of the resources used:

- `azure.core.ResourceGroup` creates an Azure Resource Group, which is a container that holds related resources for an Azure solution.
- `azure.containerservice.KubernetesCluster` provisions an AKS cluster where the worker nodes are defined with `defaultNodePool`.
- `k8s.Provider` uses the kubeconfig from the created AKS cluster to provision resources in it.
- `k8s.helm.v3.Chart` represents a Helm chart in Kubernetes; in this case, `projectsveltos`. The `chart` and `version` will need to be changed according to your specifics.

Please ensure you have all prerequisites met before running this program, such as having Pulumi installed, Azure CLI logged in, and Helm installed if necessary. After running `pulumi up`, this program will output the raw kubeconfig needed to interact with the cluster and the status of the Helm chart deployment.
