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


    To deploy the tensor_app helm chart on Azure Kubernetes Service (AKS) using Pulumi, you'll first need to set up an AKS cluster. Once the cluster is set up, you can deploy the helm chart to it.

    Here's the overview of what we're going to do:

    1. Set up an AKS cluster: We will define an AKS cluster resource. This will set up a Kubernetes cluster managed by Azure.

    2. Deploy the Helm Chart: Once the cluster is provisioned, we'll deploy the tensor_app helm chart to this cluster. We will assume tensor_app is available in a public or private Helm repository.

    Let's break down the steps and show you the Pulumi TypeScript code that accomplishes this:

    1. Setting Up an AKS Cluster

    To create an AKS cluster, we will use azure-native:containerservice:KubernetesCluster resource from the [azure-native] package. This resource allows us to define an AKS cluster with necessary properties like node size, number of nodes, etc.

    2. Deploying the Helm Chart

    Once we have the cluster, we can deploy the helm chart. The Pulumi Kubernetes provider has a Chart resource that allows us to deploy a helm chart to a Kubernetes cluster.

    Here's a comprehensive program that accomplishes these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create Azure Kubernetes Service (AKS) cluster // The exact configuration will depend on your specific requirements. const resourceGroupName = new azure_native.resources.ResourceGroup("myResourceGroup"); const aksCluster = new azure_native.containerservice.KubernetesCluster("myAKSCluster", { // Replace with the location you wish to deploy your AKS cluster in location: resourceGroupName.location, resourceGroupName: resourceGroupName.name, agentPoolProfiles: [{ count: 3, vmSize: "Standard_D2_v2", name: "agentpool", mode: "System", }], dnsPrefix: "myakscluster", // Service Principal or Managed Identity are required for AKS creation // Assume using Managed Identity here identity: { type: "SystemAssigned", }, }); // Once the AKS cluster is created, we need to configure the Kubernetes provider to use the cluster credentials. const creds = pulumi.all([aksCluster.name, resourceGroupName.name]).apply(([clusterName, rgName]) => azure_native.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, })); const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: creds.apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()), }); // Step 2: Deploy the `tensor_app` Helm chart on the AKS cluster const tensorAppChart = new k8s.helm.v3.Chart("tensorAppChart", { chart: "tensor_app", // You need to provide the repository URL where your Helm chart is located. // If it's a publicly available chart, the `repo` attribute should point to that URL. // repo: "https://<helm-repo-url>", // For simplicity, we will assume default values for the chart. // You can include custom `values` if your chart requires them. // values: { // key: "value", // }, }, { provider: k8sProvider }); // Export the `kubeconfig` to access our AKS cluster export const kubeconfig = creds.apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()); // To access the cluster, you can use the exported `kubeconfig` with kubectl or any Kubernetes management tool. // For instance, to get the list of nodes you can run `kubectl get nodes --kubeconfig ./kubeconfig.json` (assuming kubeconfig.json contains the exported `kubeconfig`).

    Make sure to replace placeholder values with actual values suitable for your setup. For example, the resourceGroupName and dnsPrefix should be unique to your deployment. For helm charts that are not publicly available, you need to provide the custom repo URL.

    Please follow the below steps to run this Pulumi program:

    1. Ensure you have Pulumi CLI installed and Azure CLI logged in to your Azure account.
    2. Save the above code to a file named index.ts.
    3. Ensure you have the necessary Pulumi packages by running the following commands:
    npm install @pulumi/pulumi npm install @pulumi/azure-native npm install @pulumi/kubernetes
    1. Run pulumi up to preview and deploy your stack.

    Remember to follow good security practices such as managing your cloud access keys securely and not leaking sensitive information in your code or outputs.
