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


    To deploy the cassandra-reaper Helm chart on Azure Kubernetes Service (AKS), you will need to create the AKS cluster first and then use the Helm chart resource from Pulumi's Kubernetes provider to deploy cassandra-reaper in your AKS cluster.

    Below, I am providing you with a Pulumi TypeScript program that will:

    1. Create an AKS cluster in Azure.
    2. Once the AKS cluster is available, install the cassandra-reaper Helm chart into it.

    For this operation, we'll use:

    • azure.containerservice.KubernetesCluster from the @pulumi/azure package to create the AKS cluster.
    • kubernetes.helm.v3.Chart from the @pulumi/kubernetes package to deploy the cassandra-reaper Helm chart.

    Here's the entire Pulumi program:

    import * as azure from "@pulumi/azure"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create an AKS cluster with default settings. For production usage, you may want to customize // it according to your needs, especially setting stronger authentication methods. const aksCluster = new azure.containerservice.KubernetesCluster("aksCluster", { resourceGroupName: "resource_group_name", // Replace with the name of the resource group dnsPrefix: "dns-prefix-for-aks", // Replace with a custom DNS prefix for the AKS cluster defaultNodePool: { name: "aksagentpool", nodeCount: 2, // Set the desired node count for your cluster vmSize: "Standard_DS2_v2", // Select an appropriate VM size }, servicePrincipal: { clientId: "client_id", // Replace with your service principal client ID clientSecret: "client_secret", // Replace with your service principal client secret }, }); // Once the cluster is created, we can obtain KubeConfig using Pulumi's built-in function const k8sConfig = pulumi. all([aksCluster.name, resourceGroupName]). apply(([clusterName, rgName]) => azure.containerservice.getKubeConfig({ name: clusterName, resourceGroupName: rgName, })); // Create a Kubernetes provider instance with the AKS cluster's KubeConfig const k8sProvider = new kubernetes.Provider("k8sProvider", { kubeconfig: k8sConfig.rawConfig, }); // Deploy the cassandra-reaper Helm chart into the AKS cluster using the Kubernetes provider const cassandraReaperChart = new kubernetes.helm.v3.Chart("cassandra-reaper", { chart: "cassandra-reaper", version: "1.0.0", // Specify the desired chart version fetchOpts:{ repo: "https://helm.reaper.io", // The Helm repository where cassandra-reaper is located }, }, { provider: k8sProvider }); // Export the cluster name and kubeconfig to interact with the AKS cluster outside Pulumi export const clusterName = aksCluster.name; export const kubeConfigRaw = k8sConfig.rawConfig;

    This Pulumi program does the following:

    • Defines the AKS cluster resource with azure.containerservice.KubernetesCluster.
    • Configures the necessary properties, like the resource group name, DNS prefix, default node pool configuration, and service principal credentials.
    • After the AKS cluster is provisioned, it captures the output of the cluster's name and resource group name to get the cluster's kubeconfig.
    • It uses the kubeconfig to set up a Kubernetes provider (k8sProvider) that tells Pulumi how to communicate with the AKS cluster.
    • With the provider set up, the program deploys the cassandra-reaper Helm chart into the AKS cluster using the kubernetes.helm.v3.Chart resource.
    • The program exports the AKS cluster's name and kubeconfig so you can interact with it using kubectl.

    To use this Pulumi program:

    1. Replace the placeholder text for resourceGroupName, dns-prefix-for-aks, client_id, and client_secret with your Azure specifics.
    2. Ensure you have Pulumi and the requisite Azure CLI tools/setup.
    3. Run pulumi up to preview and deploy the changes.

    When you run the program with pulumi up, it will provision the resources as described, and upon successful completion, you'll have the cassandra-reaper Helm chart running on your brand new AKS cluster.
