1. Deploy the hierarchical-namespace-controller helm chart on Azure Kubernetes Service (AKS)


    To deploy the "hierarchical-namespace-controller" helm chart on Azure Kubernetes Service (AKS), we will follow several steps:

    1. Provision an AKS Cluster: Before we can deploy any Helm charts, we need a Kubernetes cluster. We will create an AKS cluster using the azure-native.hybridcontainerservice.ProvisionedCluster resource from the Azure Native Pulumi provider.

    2. Install the Helm Chart: Once we have an AKS cluster, we will use the kubernetes.helm.v3.Chart resource from the Kubernetes Pulumi provider to install the "hierarchical-namespace-controller" Helm chart.

    Here's a Pulumi TypeScript program to provision the resources:

    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 = new azure_native.resources.ResourceGroup("myResourceGroup", { location: "WestUS", // You can choose a location that is appropriate for you. }); const aksCluster = new azure_native.hybridcontainerservice.ProvisionedCluster("myAKSCluster", { resourceGroupName: resourceGroupName.name, location: resourceGroupName.location, // Other properties such as the cluster configuration, node pools, and network profiles // would be set here according to your specific requirements. properties: { // Replace with your desired cluster configuration }, }); // Step 2: Install the Helm chart for hierarchical namespace controller // First, we need to create a provider that uses the newly created AKS cluster's kubeconfig. const k8sProvider = new kubernetes.Provider("k8sProvider", { kubeconfig: aksCluster.kubeconfig.apply(JSON.stringify), }); // Then we can install the Helm chart using this provider. const hierarchicalNamespaceController = new kubernetes.helm.v3.Chart("hierarchicalNamespaceController", { // Assuming the chart is available in the official Helm chart repository, // otherwise, you would need to specify the repository URL. chart: "hierarchical-namespace-controller", // Specify the chart version if needed version: "0.5.0", // Check the chart's repository for the correct version to use. // If required, you can provide a set of values to configure the chart. values: { // Replace with your chart values }, }, { provider: k8sProvider }); // Export the kubeconfig as a stack output export const kubeconfig = aksCluster.kubeconfig;


    • Resource Group: In Azure, all resources are grouped into "resource groups". We created one for our AKS cluster.

    • AKS Cluster: We defined a ProvisionedCluster resource, which represents an AKS cluster. The properties would include configurations such as node count, VM size, network settings, etc. Modify these according to your needs.

    • Kubernetes Provider: To interact with our AKS cluster using Pulumi's Kubernetes provider, we created a provider resource that depends on the kubeconfig output of our AKS cluster.

    • Helm Chart: We installed the "hierarchical-namespace-controller" Helm chart onto our AKS cluster using the Chart resource. This assumes that the chart is publicly available. If not, you might have to specify the repo parameter to point to the chart's repository URL.

    • Stack Output: We exported the kubeconfig of the AKS cluster so that you can interact with your cluster using kubectl once it's provisioned.

    Remember, this example assumes that you have configured your Pulumi CLI with the appropriate Azure credentials. You need to install the @pulumi/azure-native and @pulumi/kubernetes packages:

    npm install @pulumi/azure-native @pulumi/kubernetes

    You also need to set up the Azure CLI and log in with an account that has permissions to create resources in your subscription. When you run pulumi up, Pulumi will provision the resources defined in the code. The output of the kubeconfig will be displayed after the successful deployment, and you can use it to interact with your AKS cluster via kubectl.
