1. Deploy the stateless-istio helm chart on Azure Kubernetes Service (AKS)


    To deploy the stateless-istio Helm chart on Azure Kubernetes Service (AKS), we need to follow these steps:

    1. Define the AKS cluster resource: We define an AKS cluster resource using the azure-native.hybridcontainerservice.ProvisionedCluster resource. To configure the AKS cluster, we will need to provide details like the desired region (location), node size, Kubernetes version, etc.

    2. Create Kubernetes Provider: Once we have the AKS cluster provisioned, we need to establish a Kubernetes provider that specifies how to communicate with the AKS cluster. This uses the kubeconfig that is output from the AKS cluster creation step.

    3. Deploy Helm chart: Lastly, we can use the helm.sh/v3.Chart resource to deploy the stateless-istio chart to the AKS cluster. The chart may be deployed directly from the Helm repository where it's hosted, or from a local chart path if you have it downloaded. You will need to provide configuration values if the chart requires them.

    Here's the TypeScript program that accomplishes these tasks:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; import * as azuread from "@pulumi/azuread"; // Define the required variables for the AKS cluster const resourceName = "myAKSCluster"; // Change to whatever name you'd like to use const location = "WestUS"; // Azure region const resourceGroupName = "myResourceGroup"; // Change to your resource group // Step 1: Define the AKS cluster resource const cluster = new azure_native.hybridcontainerservice.ProvisionedCluster(resourceName, { // Required properties resourceName: resourceName, location: location, resourceGroupName: resourceGroupName, properties: { // Specify properties for the AKS cluster kubernetesVersion: "1.18.14", // Specify the desired Kubernetes version // Define the node characteristics agentPoolProfiles: [ { count: 3, vmSize: "Standard_DS2_v2", mode: "User", name: "agentpool", }, ], // Other properties and customizations can be added here }, }); // Step 2: Create a Kubernetes provider pointing to the AKS cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: cluster.kubeConfig, }); // Step 3: Deploy the stateless-istio Helm chart to the AKS cluster const statelessIstioChart = new k8s.helm.v3.Chart("stateless-istio", { chart: "stateless-istio", version: "1.0.0", // Replace with the chart version you wish to deploy fetchOpts: { repo: "http://charts.example.com/", // Replace with the Helm chart repository }, }, { provider: k8sProvider }); // Export the kubeconfig to access the AKS cluster export const kubeConfig = cluster.kubeConfig;


    • We first import the necessary Pulumi libraries for working with resources in Azure and Kubernetes.
    • We then define the necessary variables for our AKS cluster, such as name, location, and resource group. Make sure to change these to match your environment.
    • The ProvisionedCluster resource is declared to create the AKS cluster. Here you would fill in the details for your cluster, like the size and number of nodes.
    • Once the cluster is defined, a Kubernetes provider that points to the newly created AKS cluster is created. This provider is used to deploy Kubernetes resources to the cluster.
    • Finally, we define a Helm chart resource to deploy the stateless-istio chart. Make sure to replace the chart version and repository URL with appropriate values.

    The kubeConfig output from this program can be used to access the AKS cluster using kubectl or other Kubernetes tooling. You'll want to use pulumi export to retrieve the kubeconfig value once your Pulumi stack has been deployed successfully.

    Make sure to install the required Pulumi packages using npm:

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

    Also, ensure your Azure account is logged in with the Azure CLI, and Pulumi CLI is installed on your system.

    You can then run your Pulumi program with the command:

    pulumi up

    This command initializes the deployment and provisioning process. You'll be prompted with a summary of resources that will be created and asked for confirmation before proceeding. Once confirmed, Pulumi will begin orchestrating the deployment to the cloud. After the deployment is complete, you can access the Kubernetes cluster using the Kubernetes configuration output by Pulumi.
