Deploy the vmware-rest-proxy helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

To deploy the `vmware-rest-proxy` helm chart on an Azure Kubernetes Service (AKS) cluster, we will use the Pulumi Kubernetes and Azure Native providers. The Pulumi program will consist of several steps:

1. Create an AKS cluster using the `azure-native.containerservice` module.
2. Once the AKS cluster is set up, configure the Kubernetes provider to connect to the created cluster.
3. Deploy the `vmware-rest-proxy` Helm chart using the `kubernetes.helm.v3.Chart` resource.

Let's go through the steps in detail with a Pulumi program written in TypeScript.

First, we will create an AKS cluster. We need to specify the required properties like location, resource group, and the properties of the AKS cluster including the DNS prefix and the initial node count.

Next, we will configure the Kubernetes provider to use the kubeconfig from the created AKS cluster.

Finally, we’ll deploy the `vmware-rest-proxy` helm chart. You will need to specify the appropriate Helm repository containing the `vmware-rest-proxy` chart and the chart version that you wish to deploy.

Here's a complete program that demonstrates how to perform these steps:

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

// Step 1: Create an AKS cluster
const resourceGroupName = "yourResourceGroupName";
const aksClusterName = "yourAKSClusterName";

const resourceGroup = new azure_native.resources.ResourceGroup(resourceGroupName);

const aksCluster = new azure_native.containerservice.ManagedCluster(aksClusterName, {
    resourceGroupName: resourceGroupName,
    agentPoolProfiles: [{
        count: 1,
        maxPods: 110,
        mode: "System",
        name: "agentpool",
        osDiskSizeGB: 30,
        osType: "Linux",
        vmSize: "Standard_DS2_v2",
    }],
    dnsPrefix: `${aksClusterName}-dns`,
    enableRBAC: true,
    kubernetesVersion: "1.19.11",
    location: resourceGroup.location,
    nodeResourceGroup: `MC_${resourceGroupName}_${aksClusterName}_${resourceGroup.location}`,
}, { dependsOn: resourceGroup });

// Step 2: Configure Kubernetes provider to connect to the created AKS cluster
const creds = pulumi.all([aksCluster.name, resourceGroup.name]).apply(([name, rgName]) => 
    azure_native.containerservice.listManagedClusterUserCredentials({
        resourceGroupName: rgName,
        resourceName: name,
    }));

const kubeconfig = creds.apply(creds => {
    const encoded = creds.kubeconfigs[0].value;
    const buff = new Buffer(encoded, 'base64');
    return buff.toString('utf-8');
});

const k8sProvider = new kubernetes.Provider("k8s-provider", {
    kubeconfig: kubeconfig,
});

// Step 3: Deploy the vmware-rest-proxy Helm chart on the AKS cluster
const chart = new kubernetes.helm.v3.Chart("vmware-rest-proxy", {
    chart: "vmware-rest-proxy",
    version: "1.0.0", // replace with your desired chart version
    fetchOpts: {
        repo: "http://your-helm-chart-repository/", // replace with the URL of the chart repository
    },
}, { provider: k8sProvider });

// Export the kubeconfig and AKS cluster name
export const kubeconfigOutput = pulumi.secret(kubeconfig);
export const clusterName = aksCluster.name;
```

Before running this program, make sure you have the Pulumi CLI installed and configured for use with your Azure account credentials. You also need to have Node.js installed to execute the TypeScript code.

Replace the placeholders (like `yourResourceGroupName`, `yourAKSClusterName`, `http://your-helm-chart-repository/`, and `1.0.0`) with the actual values you want to use for your deployment. The location for creating the resource group and the AKS cluster will be picked up from your Azure configuration, or you can specify a particular location if required.

In case your Helm chart requires additional configurations, you can specify those in a values file or directly in the `values` property of the Helm chart resource.

This program will create an AKS cluster, set up the Kubernetes provider, and deploy the `vmware-rest-proxy` Helm chart to the cluster. The kubeconfig needed to interact with the cluster with `kubectl` is exported as a secret output for security reasons.
