1. Deploy the ibm-glusterfs helm chart on Azure Kubernetes Service (AKS)


    To deploy the IBM GlusterFS Helm chart on Azure Kubernetes Service (AKS), we'll go through a set of steps using Pulumi and its Azure Native provider. Here's a high-level outline of the process we'll follow:

    1. Set up an AKS cluster using Pulumi.
    2. Install the Helm chart for IBM GlusterFS on the AKS cluster.

    Before we begin, make sure you have Pulumi installed and configured with Azure, along with kubectl and Helm CLI installed for interacting with the Kubernetes cluster.

    Step 1: Provision an AKS Cluster

    Firstly, we'll define an AKS cluster using Pulumi. We'll specify the necessary configuration like the number of nodes, the size of the nodes, and more. This AKS cluster will then provide the Kubernetes environment where our Helm chart will be deployed.

    Step 2: Deploy IBM GlusterFS Helm Chart

    Once the AKS cluster is up and running, we'll use Pulumi to deploy the IBM GlusterFS Helm chart onto the cluster. Pulumi allows us to manage Helm charts as resources within our TypeScript program.

    Let's start writing our Pulumi program in TypeScript:

    import * as azure from "@pulumi/azure"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create an Azure Resource Group const resourceGroup = new azure.core.ResourceGroup("myResourceGroup", { location: "West US", }); // Create an AKS cluster const cluster = new azure.containerservice.KubernetesCluster("myAksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, maxPods: 110, mode: "System", name: "agentpool", osDiskSizeGb: 30, osType: "Linux", vmSize: "Standard_DS2_v2", vnetSubnetId: null, // Provide the virtual network subnet id if AKS is not allowed to create its own vnet }], dnsPrefix: "myakscluster", enableRBAC: true, // Enable Kubernetes RBAC for the cluster kubernetesVersion: "1.19.11", linuxProfile: { // Provide an SSH key to use with the Kubernetes cluster adminUsername: "azureuser", sshKey: { keyData: "ssh-rsa AAAAB3NzaC1y...", }, }, identity: { type: "SystemAssigned", }, }); // Export the kubeconfig export const kubeconfig = cluster.kubeConfigRaw; // Create a Kubernetes provider instance that uses our AKS kubeconfig const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: cluster.kubeConfigRaw, }); // Deploy IBM GlusterFS helm chart using the k8s provider const glusterfsChart = new k8s.helm.v3.Chart("ibm-glusterfs", { chart: "glusterfs", fetchOpts: { repo: "https://ibm.github.io/ibm-glusterfs/", // Make sure this is the correct Helm chart repository }, }, { provider: k8sProvider }); // Export the Helm chart deployment status export const helmChartStatus = glusterfsChart.status;

    This program will perform the following actions:

    • Import the required libraries from Pulumi's Azure and Kubernetes providers.
    • Create a new Azure resource group to hold our AKS cluster.
    • Provision an AKS cluster with 2 nodes using Standard_DS2_v2 size for the virtual machines and enabling Kubernetes RBAC.
    • Configure SSH access to the cluster's nodes with an SSH key.
    • Export the Kubernetes configuration needed to interact with the AKS cluster.
    • Set up the Kubernetes provider that Pulumi will use to interact with the AKS cluster.
    • Deploy the Helm chart for IBM GlusterFS using the Helm v3 Pulumi provider to the configured AKS cluster.
    • Export the Helm chart deployment's status as an output of the Pulumi program.

    Remember to replace the SSH key and potentially update the Helm chart repository URL to the correct one where the IBM GlusterFS Helm chart is hosted.

    After writing this program, you would run it using Pulumi CLI commands pulumi up to create the resources or pulumi destroy to tear them down. Keep in mind that you might need to change some details, like the SSH public key (keyData) or the GlusterFS Helm chart name and version, depending on your specific needs.

    Finally, make sure you are aware of the costs associated with running an AKS cluster on Azure and the network policies or other specific configurations your workload might require.
