1. Deploy the ibm-open-liberty helm chart on Azure Managed Openshift Service

    TypeScript

    To deploy the ibm-open-liberty Helm chart on Azure Managed Openshift Service using Pulumi, you'll go through the following steps:

    1. Set up an Azure Managed OpenShift Cluster: First, you must have an OpenShift cluster running on Azure. You will use the azure-native.containerservice.OpenShiftManagedCluster resource to create a managed OpenShift cluster.

    2. Install the Helm Chart: Once the cluster is up and running, you will use the kubernetes.helm.v3.Chart resource to deploy the ibm-open-liberty Helm chart on the OpenShift cluster.

    Here's how you could write a Pulumi program in TypeScript to achieve these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create an Azure Resource Group const resourceGroup = new azure.resources.ResourceGroup("openLibertyRg", { location: azure.Locations.EastUS, // You can choose the appropriate Azure region }); // Create an Azure Managed OpenShift Cluster const cluster = new azure.containerservice.OpenShiftManagedCluster("openLibertyCluster", { resourceGroupName: resourceGroup.name, location: resourceGroup.location, openShiftVersion: "4.3", // Specify the OpenShift version you want to deploy networkProfile: { vnetCidr: "10.0.0.0/8", }, masterPoolProfile: { name: "master", count: 3, vmSize: "Standard_D4s_v3", // Ensure the VM size is appropriate for your needs }, // For the sake of simplicity, a single agent pool is defined here. // You can create more pools tailored to your application requirements. agentPoolProfiles: [{ name: "agentpool", count: 3, vmSize: "Standard_D4s_v3", }], // Define the authentication profile for the cluster authProfile: { identityProviders: [{ name: "Azure AD", provider: { kind: "AADIdentityProvider", clientId: "<Azure_AD_Client_ID>", secret: "<Azure_AD_Secret>", tenantId: "<Azure_AD_Tenant_ID>", }, }], }, }); // Initialize the Kubernetes provider using the created OpenShift cluster details const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: cluster.config.rawConfig.apply(cfg => cfg!), // Access the kubeconfig from the created cluster }); // Deploy the ibm-open-liberty Helm chart const helmChart = new k8s.helm.v3.Chart("ibm-open-liberty", { chart: "ibm-open-liberty", version: "3.2.3", // Specify the version of the Helm chart you want to deploy fetchOpts: { repo: "https://charts.bitnami.com/bitnami", // Replace with the correct Helm repository for ibm-open-liberty }, }, { provider: k8sProvider }); // Export the Kubernetes cluster name and kubeconfig export const kubeconfig = cluster.config.rawConfig; export const clusterName = cluster.name;

    Explanation:

    • We start by importing the necessary Pulumi libraries. We need @pulumi/pulumi for core Pulumi functionalities, @pulumi/azure-native to interact with Azure resources, and @pulumi/kubernetes to work with Kubernetes resources, including Helm charts.

    • We declare an Azure Resource Group resourceGroup to organize all our resources.

    • We create an Azure Managed OpenShift Cluster cluster with the necessary configurations. Make sure to replace placeholders like <Azure_AD_Client_ID>, <Azure_AD_Secret>, and <Azure_AD_Tenant_ID> with your real Azure Active Directory credentials. Customize the openShiftVersion, vmSize, and other parameters according to your requirements.

    • We then initialize a Kubernetes provider k8sProvider using the kubeconfig of the OpenShift cluster we just created.

    • After setting up the Kubernetes provider, we declare a Helm chart helmChart using the kubernetes.helm.v3.Chart resource, pointing to the ibm-open-liberty chart. Please note that you will have to replace the repo with the correct Helm repository URL if ibm-open-liberty is not located in the Bitnami repository. Also, specify the appropriate version of the chart.

    • Lastly, we export the kubeconfig and the name of the cluster for easy access. Exported values can be used if you want to configure additional resources or accesses manually.

    Remember to set up your Pulumi project and install the necessary Pulumi CLI and Azure provider credentials before running this code.
