1. Deploy the tenant-manager helm chart on Azure Kubernetes Service (AKS)

    TypeScript

    To deploy the tenant-manager Helm chart on Azure Kubernetes Service (AKS), we'll proceed with the following steps:

    1. Create an Azure Kubernetes Service (AKS) cluster.
    2. Deploy the tenant-manager Helm chart onto the AKS cluster.

    In Pulumi, you use the @pulumi/azure-native package to create cloud resources like AKS, and the @pulumi/kubernetes package to deploy Helm charts. The azure-native package uses the newer Azure Resource Manager (ARM) API directly, which is the preferred method for managing Azure resources.

    Below is a Pulumi program in TypeScript that will:

    • Create an AKS cluster.
    • Configure a Kubernetes provider that uses the AKS cluster's kubeconfig.
    • Use the Kubernetes provider to deploy a Helm chart.

    First, let's lay out the resources we'll be using and why:

    • azure-native.resources.ResourceGroup: A resource group to contain all the resources.
    • azure-native.containerservice.ManagedCluster: The AKS cluster resource.
    • kubernetes.helm.v3.Chart: The Helm chart resource, which Pulumi will manage through the Kubernetes provider.

    Now let's get started with the code:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create a new Azure resource group const resourceGroup = new azure_native.resources.ResourceGroup("myResourceGroup"); // Step 2: Create the AKS cluster const managedCluster = new azure_native.containerservice.ManagedCluster("myAKSCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, vmSize: "Standard_DS2_v2", name: "agentpool", }], dnsPrefix: "myakscluster", enableRBAC: true, }); // Obtain the KubeConfig from the AKS cluster const kubeConfig = pulumi.all([managedCluster.name, resourceGroup.name]).apply(([clusterName, rgName]) => { return azure_native.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, }); }).apply(creds => { const encoded = creds.kubeconfigs[0].value; if (encoded === undefined) { throw new Error("kubeconfig is undefined"); } const kubeconfig = Buffer.from(encoded, 'base64').toString(); return kubeconfig; }); // Step 3: Create a Kubernetes provider instance that uses the kubeconfig const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeConfig, }); // Step 4: Deploy the tenant-manager Helm chart const tenantManagerChart = new k8s.helm.v3.Chart("tenant-manager", { chart: "tenant-manager", // Replace with the actual repo URL or name in your Helm chart repository. fetchOpts: { repo: "http://<YOUR_HELM_CHART_REPO>", }, // You can specify the chart version and values here if needed. }, { provider: k8sProvider }); // Export the kubeconfig and cluster name export const kubeConfigOutput = kubeConfig; export const clusterName = managedCluster.name;

    Explanation:

    • We start by importing the necessary Pulumi libraries.
    • We create an Azure resource group to hold our cluster.
    • We set up the AKS cluster with two nodes in the agentpool agent pool, RBAC enabled, and a DNS prefix.
    • We retrieve the kubeconfig, which will allow us to interact with our AKS cluster programmatically.
    • We instantiate a Kubernetes provider, configuring it with the kubeconfig from our AKS cluster.
    • We deploy the tenant-manager Helm chart using the Kubernetes provider we just created. The fetchOpts.repo is the Helm repository you have pushed the tenant-manager chart to, you should replace <YOUR_HELM_CHART_REPO> with the URL of your repository.
    • We export the kubeconfig and the cluster name for easy access.

    Make sure you have the AKS cluster ready and have access to the Helm chart repository where tenant-manager is stored. If you would like to pass any specific configurations to your Helm chart, you can include them in the values property within the tenantManagerChart declaration.

    To run this Pulumi program, save it to a file (e.g., index.ts), and run pulumi up using the Pulumi CLI. This command will provision the resources as defined in the code. Ensure you have the required Pulumi stack configuration set up, including authentication details for the Azure cloud provider.
