1. Deploy the stable helm chart on Azure Kubernetes Service (AKS)


    To accomplish the deployment of a Helm chart on Azure Kubernetes Service (AKS) using Pulumi, you would typically follow a series of steps. First, you'd create an AKS cluster, and then deploy a Helm chart within that cluster. For the Helm chart deployment, the kubernetes.helm.v3.Chart resource is commonly used; this resource allows you to define a Helm chart deployment similarly to how you would use helm CLI commands, but with the added benefits of Pulumi's infrastructure as code approach.

    Here is a TypeScript program that demonstrates how to create an AKS cluster and deploy a stable Helm chart to it:

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure"; import * as k8s from "@pulumi/kubernetes"; import * as kubernetes from "@pulumi/kubernetes"; // Create an AKS cluster. const aksCluster = new azure.containerservice.KubernetesCluster("my-aks-cluster", { defaultNodePool: { name: "aksagentpool", nodeCount: 2, vmSize: "Standard_D2_v2", }, dnsPrefix: "my-kube-dns", resourceGroupName: "my-resource-group", }); // Export the kubeconfig for the AKS cluster. const kubeconfig = aksCluster.kubeConfigRaw; export const kubeconfigOutput = pulumi.secret(kubeconfig); // Create a provider for the AKS cluster using the exported kubeconfig. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Deploy a stable Helm chart into the AKS cluster. const helmChart = new kubernetes.helm.v3.Chart("my-helm-chart", { chart: "nginx", // Replace with your desired Helm chart version: "1.16.0", // Specify the chart version. Adjust as needed. namespace: "default", // Specify the Kubernetes namespace. fetchOpts: { repo: "https://charts.helm.sh/stable", // Specify the chart repository. }, }, { provider: k8sProvider }); // You could expose any output from the Helm chart that you may need. // export const frontendServiceIP = helmChart.getResourceProperty( // "v1/Service", "my-helm-chart-nginx", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Let's break down the program:

    1. We import the necessary Pulumi packages: @pulumi/pulumi, @pulumi/azure, @pulumi/kubernetes, and the actual Kubernetes package with helm charts @pulumi/kubernetes.

    2. We create an AKS cluster by using the KubernetesCluster resource from the @pulumi/azure package. Here, you define the node pool, DNS prefix, and the resource group where the cluster resides.

    3. The kubeConfigRaw output from the AKS cluster is then exported as a secret. This kubeconfig will later allow you to interact with your Kubernetes cluster.

    4. Using that kubeconfig, we instantiate a Pulumi Kubernetes provider. This provider is required to deploy Kubernetes resources onto the created AKS cluster.

    5. Deploy the specified Helm chart using the kubernetes.helm.v3.Chart resource. This resource needs details about the Helm chart and the repository where the chart is hosted. The provider option ensures that the Helm chart is deployed into our AKS cluster.

    6. Optionally, you could export additional outputs, such as the external IP of a front-end service deployed by your Helm chart.

    Please adjust the parameters such as the Helm chart to be deployed (nginx in the example), the chart version, and the repository URL (https://charts.helm.sh/stable) according to your needs. The namespace is set to default, but if your chart should be deployed to a different namespace, you'll need to change that as well.
