1. Deploy the ibm-odm-prod helm chart on Azure Managed Openshift Service


    To deploy the IBM Operational Decision Manager (ODM) chart on Azure Managed OpenShift Service using Pulumi, you would typically need to perform the following steps:

    1. Set up an Azure Managed OpenShift cluster (also known as Azure Red Hat OpenShift or ARO).
    2. Configure the Kubernetes provider to interact with your ARO cluster.
    3. Use the Helm chart resource to deploy the IBM ODM helm chart to the OpenShift cluster.

    Before you start, ensure that you have the following prerequisites:

    • An Azure account with the appropriate permissions.
    • The az CLI installed and configured.
    • A Kubernetes configuration file (kubeconfig) that grants access to your OpenShift cluster.
    • Pulumi CLI installed and set up to manage your infrastructure.

    The following program in TypeScript uses Pulumi to achieve your goal:

    import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; import * as azureNative from "@pulumi/azure-native"; // First, we create the Azure Managed OpenShift cluster. const cluster = new azureNative.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", { // Replace the following properties with the appropriate values for your environment. resourceGroupName: "myResourceGroup", location: "East US", // The Azure region where you want to create your cluster. openShiftVersion: "4.3", // The OpenShift version to deploy. masterPoolProfile: { // Details such as the size and count of master nodes go here. count: 3, vmSize: "Standard_D4s_v3", }, agentPoolProfiles: [{ // Details such as the size, count, and role of agent nodes go here. name: "agentpool", count: 3, vmSize: "Standard_D4s_v3", role: "compute", }], // Additional required configuration details go here, such as network profile, auth profile, and so on. }); // Make sure to use the correct kubeconfig to point to the created OpenShift cluster. const kubeconfig = "..."; // Your OpenShift cluster kubeconfig content as a string. // Configure the Kubernetes provider to interact with the OpenShift cluster. const k8sProvider = new kubernetes.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // Now we're ready to deploy the IBM ODM helm chart to the OpenShift cluster. const odmChart = new kubernetes.helm.v3.Chart("ibm-odm-prod-chart", { repo: "ibm-charts", // The name of the repository where the ODM chart is located. chart: "ibm-odm-prod", // The name of the chart to deploy. version: "YOUR_CHART_VERSION", // Specify the version of the IBM ODM chart you wish to deploy. // Insert any custom values you want to override in the IBM ODM chart. values: { // Your custom values go here. }, }, { provider: k8sProvider }); // Finally, we can export the important details that we might need to use later on. export const clusterName = cluster.name; export const kubeconfigOutput = kubeconfig;

    Detailed Explanation:

    • You first create an instance of the Azure Managed OpenShift Cluster using the azureNative.containerservice.OpenShiftManagedCluster class. This will set up the underlying infrastructure on Azure for running OpenShift. You need to replace placeholders like myResourceGroup and "East US" with your actual resource group and preferred Azure location.

    • The master and agent pool profiles are configured according to the size and number that you need. You need to provide the VM size and count for both master and agent nodes.

    • The Kubernetes provider (k8sProvider) is then configured using the output kubeconfig from the OpenShift cluster creation. This will enable Pulumi to communicate with your OpenShift cluster and manage Kubernetes resources.

    • With the Kubernetes provider set up, you use the kubernetes.helm.v3.Chart class to deploy the IBM ODM helm chart. Here, replace "YOUR_CHART_VERSION" with the ODM helm chart version you wish to use and populate the values field with any overrides required for the IBM ODM configurations.

    • The exported outputs, clusterName and kubeconfigOutput, are useful for accessing the cluster and performing other operations in the future using Pulumi or other tools.

    Remember that deploying a large system like IBM ODM may involve many other details and configurations based on your specific use case, which can be reflected in the values field of the Helm chart resource definition.

    Ensure that you have the IBM ODM Helm chart available in your configured Helm repository (ibm-charts) and that you provide the correct path and credentials to your kubeconfig when configuring the Kubernetes provider.
