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


    To deploy the ibm-mq-operator Helm chart on Azure Kubernetes Service (AKS), you will need to perform the following steps:

    1. Create an AKS cluster: You'll need an AKS cluster where the Helm chart will be deployed.
    2. Install the Helm chart: Using Pulumi's Helm chart support, you can deploy the ibm-mq-operator chart to your AKS cluster.

    Below is a TypeScript program using Pulumi which accomplishes these steps.

    Detailed Explanation


    Before you get started with Pulumi, you should have the following prerequisites:

    • An Azure subscription.
    • The Azure CLI installed and configured.
    • Pulumi CLI installed.
    • Node.js installed, as we're using TypeScript.

    Creating the AKS Cluster

    First, we are going to set up an AKS cluster using the azure-native:containerservice:KubernetesCluster resource. This is an azure-native Pulumi resource, which is the direct way to create resources with Pulumi using ARM templates as the provision method.

    Installing the Helm Chart

    After we have a running AKS cluster, we leverage Pulumi’s kubernetes.helm.v3.Chart resource to deploy the ibm-mq-operator chart. The Helm chart will be sourced from the Helm repository where ibm-mq-operator is hosted.

    The kubernetes.helm.v3.Chart resource allows us to install Helm charts in a Kubernetes cluster. We need to provide the repository URL where the Helm chart is located, and Pulumi will handle the fetching and installation.

    Pulumi Program

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; import * as azuread from "@pulumi/azuread"; // Create a new AKS cluster. const cluster = new azure.containerservice.KubernetesCluster("aksCluster", { // Other required properties, such as resource group, etc., will be determined by your specific setup resourceGroupName: "yourResourceGroup", location: "West US", // Define your cluster configuration here identity: { type: "SystemAssigned" }, defaultNodePool: { name: "aksagentpool", count: 3, vmSize: "Standard_DS2_v2" }, dnsPrefix: "aksSample", }); // Export the kubeconfig to access the AKS cluster export const kubeConfig = pulumi.all([cluster.name, resourceGroup.name]).apply(([clusterName, rgName]) => { return azure.containerservice.listManagedClusterUserCredentials({ resourceName: clusterName, resourceGroupName: rgName, }); }).apply(credentials => { const encoded = credentials.kubeconfigs[0].value; return Buffer.from(encoded, 'base64').toString(); }); // Deploy the ibm-mq-operator Helm chart into the AKS cluster const mqOperatorChart = new k8s.helm.v3.Chart("ibm-mq-operator-chart", { chart: "ibm-mq-operator", version: "1.0.0", // specify the version you want to deploy fetchOpts: { repo: "https://charts.your-repo.com/", // replace this with the Helm repo URL for ibm-mq-operator }, // Values to override in the Helm chart values: { // place your values overrides here, for example replicaCount: 2, }, }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: kubeConfig }) }); // Export the resources export const aksClusterName = cluster.name; export const mqOperatorChartName = mqOperatorChart.getResource("v1/Secret", "ibm-mq-operator-chart");

    How to Use the Program

    To use the TypeScript program above:

    • Save the code in a file named index.ts.
    • Run npm install to install the necessary Pulumi libraries.
    • Use pulumi up to create the resources in Azure.

    This program will:

    • Provision an AKS cluster in the provided resource group.
    • Use the output of the AKS creation, namely the kubeconfig, as input for setting up the Helm provider.
    • Deploy the ibm-mq-operator Helm chart to the AKS cluster with the specified version and values.

    Remember to replace placeholder values such as yourResourceGroup and https://charts.your-repo.com/ with actual values for your setup. Also, you need to ensure the Helm chart values and version are appropriate for your deployment needs.
