1. Deploy the rke2-cilium helm chart on Azure Kubernetes Service (AKS)


    In this Pulumi program, we're going to deploy the rke2-cilium Helm chart onto an Azure Kubernetes Service (AKS) cluster. We'll first create an AKS cluster, then we'll deploy the Helm chart onto this newly created cluster.

    Here's what we're going to do:

    1. Provision an AKS Cluster: We'll create an AKS cluster using Pulumi's azure-native package, which provides native Azure resources.
    2. Deploy Helm Chart: After the cluster is provisioned, we'll deploy the Helm chart to the AKS cluster using Pulumi's kubernetes package that allows for management of Kubernetes resources, including Helm charts.

    Step 1: Provision an AKS Cluster

    We'll need to create a new AKS cluster, including all dependent resources like the Kubernetes version, Node pool for our worker nodes, and any necessary configurations such as networking.

    Step 2: Deploy Helm Chart

    Once the AKS cluster is up and running, we'll configure Pulumi to use the Kubernetes cluster by setting up the KubeConfig. After that, we'll use Pulumi's helm package to deploy the rke2-cilium chart.

    Below is the full TypeScript program that accomplishes these steps. Before running this program, ensure you've installed Pulumi and set up the Azure provider.

    import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create a new resource group to contain our AKS cluster const resourceGroup = new azure.resources.ResourceGroup("aksResourceGroup"); // Create the AKS cluster const cluster = new azure.containerservice.ManagedCluster("aksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, maxPods: 110, mode: "System", name: "agentpool", osType: "Linux", vmSize: "Standard_DS2_v2", vnetSubnetID: subnet.id, }], dnsPrefix: "aksk8s" }); // Export the Kubernetes kubeconfig export const kubeconfig = pulumi. all([cluster.name, resourceGroup.name]). apply(([clusterName, rgName]) => azure.containerservice.listManagedClusterUserCredentials({ resourceName: clusterName, resourceGroupName: rgName, }) ). apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()); // Create a Kubernetes provider instance that uses our kubeconfig const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig }); // Deploy the rke2-cilium Helm chart onto our AKS cluster const rke2CiliumChart = new k8s.helm.v3.Chart("rke2-cilium", { chart: "cilium", version: "1.9.1", fetchOpts: { // The repository that hosts the rke2-cilium Helm chart needs to be specified repo: "https://helm.cilium.io/", }, namespace: "kube-system", }, { provider: k8sProvider }); // Export the public Cluster IP of the Helm release export const rke2CiliumPublicIP = rke2CiliumChart.getResource("v1/Service", "kube-system", "rke2-cilium").status.loadBalancer.ingress[0].ip;

    In this program, a new Azure Kubernetes Service cluster is provisioned within an Azure resource group. We specify the settings of the AKS cluster such as the Kubernetes version, node size, and number of nodes.

    We then configure Pulumi to use the kubeconfig of this cluster, which is needed to interact with the cluster. This configuration is applied to a new Pulumi Kubernetes provider, which allows us to deploy Kubernetes resources.

    We proceed by deploying the 'rke2-cilium' Helm chart using Pulumi's Helm chart resource. This Helm chart is a pre-packaged set of Kubernetes resources for cilium, a Kubernetes CNI.

    For the chart to be installed, we specify the version and the repository from which the chart can be fetched.

    Finally, we're exporting the public IP of the cilium service to make it accessible for future use with the export statement.
