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


    To deploy the IPsec Helm chart on Azure Kubernetes Service (AKS), we'll create a Pulumi program in TypeScript. This program will consist of a few steps:

    1. Create an AKS cluster: We need an AKS cluster where our IPsec application will run. We'll define an AKS cluster resource using Pulumi.

    2. Deploy the Helm chart: Once we have the AKS cluster, we'll use Pulumi's Helm Chart resource to deploy IPsec to it.

    Here's a detailed plan of what each part of the Pulumi program does:

    • Azure Kubernetes Service (AKS): We'll set up a Kubernetes cluster on Azure using the ProvisionedCluster resource from the azure-native package. This resource allows provisioning an AKS cluster with a specification that includes node size, the number of nodes, and other configurations.

    • Helm Chart: We'll use Pulumi's Chart resource from the kubernetes package to deploy the IPsec Helm chart. This resource accepts the name of the chart and other optional parameters like values overrides, which you can use to customize your Helm chart deployment.

    Let's get started with the Pulumi TypeScript program that accomplishes these steps. Make sure you have Pulumi and necessary providers installed, and you are authenticated with Azure where you plan to deploy the AKS cluster and the IPsec application.

    import * as azure from "@pulumi/azure-native"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1: Create an AKS cluster const resourceGroup = new azure.resources.ResourceGroup("aksResourceGroup"); const aksCluster = new azure.containerservice.ManagedCluster("aksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, maxPods: 110, mode: "System", name: "agentpool", osType: "Linux", vmSize: "Standard_DS2_v2", }], dnsPrefix: `${pulumi.getStack()}-kube`, enableRBAC: true, kubernetesVersion: "1.18.14", linuxProfile: { adminUsername: "adminuser", ssh: { publicKeys: [{ keyData: "ssh-rsa ...", // replace with your SSH public key }], }, }, nodeResourceGroup: `MC_azure-${pulumi.getStack()}_aksCluster_${resourceGroup.location}`, resourceGroupName: resourceGroup.name, servicePrincipalProfile: { clientId: "INSERT_SP_APP_ID", // replace with your Service Principal App ID secret: "INSERT_SP_SECRET", // replace with your Service Principal Secret }, }); // Step 2: Deploy the Helm chart const k8sProvider = new kubernetes.Provider("k8sProvider", { kubeconfig: aksCluster.kubeConfigRaw, }); const chart = new kubernetes.helm.v3.Chart("ipsecChart", { chart: "ipsec", // As an example, we specify the version to a hypothetical "1.2.3" version: "1.2.3", // Replace below with the Helm repo where your IPsec chart is located fetchOpts: { repo: "https://charts.example.com/", }, }, { provider: k8sProvider }); export const aksClusterName = aksCluster.name; export const kubeconfig = aksCluster.kubeConfigRaw;

    In this program:

    • We start by creating a new resource group for our AKS resources.
    • We then provision a new AKS cluster with two nodes (agentPoolProfiles.count: 2), specifying the size of the VMs and enabling RBAC for security.
    • The kubernetesVersion is set, but you would typically use the latest supported version.
    • Service Principal credentials are used to create the AKS cluster. You need to replace INSERT_SP_APP_ID and INSERT_SP_SECRET with your actual Service Principal Application ID and Secret.
    • For SSH access to the nodes, we specify an SSH public key.
    • Once the AKS cluster is created, we instantiate a Pulumi Kubernetes provider pointing to our new AKS cluster using its kubeConfigRaw.
    • We deploy the IPsec helm chart to the cluster. You need to replace the chart version and repo with the actual Helm chart you want to use.
    • The program exports the name of the AKS cluster and the raw Kubernetes config, which can be used to access the Kubernetes cluster via kubectl.

    After writing this code, save this into a .ts file, and use the Pulumi CLI to create a new stack and update it. During the update, Pulumi will provision the AKS cluster and deploy your Helm chart automatically.

    Please ensure that you have replaced the placeholders with actual values before running Pulumi commands to deploy this stack, such as your SSH public key and your Service Principal credentials.
