1. Deploy the pod-reaper helm chart on Azure Kubernetes Service (AKS)

    TypeScript

    To deploy the Pod Reaper Helm chart on an Azure Kubernetes Service (AKS) cluster using Pulumi, we'll need to complete a few steps:

    1. Set up an AKS Cluster: We'll first create an AKS cluster where our application will be deployed. This involves defining a resource group and the AKS cluster itself.

    2. Install the Helm Chart: Once we have our Kubernetes cluster set up, we'll use Pulumi's Kubernetes provider to install the Pod Reaper Helm chart into our AKS cluster.

    Here's a detailed plan of what we are going to do in the Pulumi TypeScript program:

    • Import necessary Pulumi packages to create Azure resources and to work with Kubernetes and Helm charts.
    • Create a new resource group using the Azure Native provider.
    • Create a new AKS cluster within our resource group.
    • Configure Pulumi to use the generated kubeconfig from the created AKS cluster.
    • Deploy the Pod Reaper Helm chart to our AKS cluster using the Helm Release resource.

    Below is the TypeScript program that accomplishes the above steps:

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure"; import * as azuread from "@pulumi/azuread"; import * as k8s from "@pulumi/kubernetes"; import * as azureNative from "@pulumi/azure-native"; // Step 1: Create an Azure Resource Group const resourceGroup = new azureNative.resources.ResourceGroup("resourceGroup"); // Step 2: Create an AKS cluster const aksCluster = new azure.containerservice.KubernetesCluster("aksCluster", { // Resource configuration options would be here, including the location (region), the size of the nodes, etc. resourceGroupName: resourceGroup.name, defaultNodePool: { name: "aksagentpool", nodeCount: 1, vmSize: "Standard_DS2_v2", }, dnsPrefix: `${pulumi.getStack()}-kube`, identity: { type: "SystemAssigned", }, }); // Output the kubeconfig to connect to the AKS cluster export const kubeconfig = aksCluster.kubeConfigRaw; // Create a Provider to host the Helm chart // This step assumes that the AKS cluster is already created and available. const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: aksCluster.kubeConfigRaw, }); // Step 3: Deploy the Pod Reaper Helm chart using the AKS cluster's Provider const podReaperChart = new k8s.helm.v3.Chart("pod-reaper", { chart: "pod-reaper", version: "1.0.0", // Specify the version of the Helm chart if needed fetchOpts: { repo: "https://example.com/helm-charts", // Specify the Helm chart repository URL }, }, { provider: k8sProvider }); // Export the Kubernetes provider's ID, which is needed for further updates export const k8sProviderId = k8sProvider.id;

    Breakdown of the code:

    • Resource Group: We begin by creating a resource group, which is a collection that holds related resources for an Azure solution.

    • AKS Cluster: We then define the AKS cluster, which includes the type and number of nodes and the identity of the cluster.

    • Kubeconfig: We export the kubeconfig of the cluster, which allows us to interact with our AKS cluster using kubectl and other Kubernetes tools.

    • Kubernetes Provider: This is used by Pulumi to communicate with the created AKS cluster and to manage Kubernetes resources.

    • Helm Chart: Finally, we deploy the Pod Reaper Helm chart using the k8s.helm.v3.Chart resource. This resource will install the given Helm chart in our AKS cluster using the provided details like chart, version, and fetchOpts. You will need to substitute the repo value in fetchOpts with the actual Helm repository URL where the Pod Reaper chart is located.

    To run this Pulumi program:

    1. Ensure you have the Pulumi CLI installed and configured for Azure.
    2. Save the above code to a file named index.ts.
    3. Run pulumi stack init to create a new stack.
    4. Run pulumi up to execute the code and create the resources.

    Please replace placeholders like the Helm chart version and repository with actual values that are applicable to the Pod Reaper Helm chart you intend to deploy.
