1. Deploy the cinder helm chart on Azure Managed Openshift Service


    Deploying a Helm chart to a Kubernetes cluster, like Azure's Managed OpenShift Service, involves a few key steps. The Pulumi program will need to do the following:

    1. Provision the Azure Managed OpenShift Service where the Helm chart will be deployed.
    2. Install the Helm chart into the OpenShift cluster.

    To accomplish this, you'll use the Pulumi azure-native package to create the managed OpenShift cluster and the kubernetes package to deploy the Helm chart to that cluster.

    Let's write the Pulumi program in TypeScript to achieve this. I'll break down each part and include comments throughout the code to help you understand what's happening at every step:

    1. First, we'll create the OpenShift cluster.
    2. Then, we will configure the Kubernetes provider to target the newly created OpenShift cluster.
    3. Next, we'll use the Kubernetes provider to deploy the cinder Helm chart.

    Here's a complete Pulumi program to deploy the cinder Helm chart on Azure Managed OpenShift Service:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Provision an Azure Managed OpenShift Service cluster const resourceGroupName = new azure_native.resources.ResourceGroup("rg", { resourceGroupName: "myResourceGroup", location: "East US", }); const openShiftCluster = new azure_native.containerservice.OpenShiftManagedCluster("openshiftCluster", { // Be sure to replace these with actual values or configuration references resourceName: "myOpenShiftCluster", resourceGroupName: resourceGroupName.name, location: resourceGroupName.location, openShiftVersion: "v4.3", networkProfile: { // Define your network profile here }, masterPoolProfile: { // Define your master node pool profile here }, agentPoolProfiles: [{ // Define your agent node pool profile here }], }); // Step 2: Configure the Kubernetes provider to use the OpenShift cluster credentials // This step often involves getting the kubeconfig data for the OpenShift cluster // The following is a placeholder and should be replaced with actual kubeconfig retrieval process const openshiftKubeConfig = pulumi.secret("my-kubeconfig"); // This should be securely retrieved from Azure const k8sProvider = new k8s.Provider("openshiftK8sProvider", { kubeconfig: openshiftKubeConfig, }); // Step 3: Deploy the cinder Helm chart using the Kubernetes provider const cinderChart = new k8s.helm.v3.Chart("cinder", { chart: "cinder", version: "1.2.3", // specify the version of the chart namespace: "default", // Set any required values for your Helm chart deployment values: { // Use the appropriate values for the cinder Helm chart }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and the service endpoint export const kubeconfig = openshiftKubeConfig; export const cinderServiceEndpoint = cinderChart.getResourceProperty("v1/Service", "cinder-service", "status");

    Let's break down the code:

    • I created a new resource group to contain all the Azure resources, including the OpenShift cluster.
    • Then, I instantiated an Azure Managed OpenShift Service cluster, specifying some placeholder configurations for the network profile and node pools, which you will need to configure based on your specific requirements.
    • After the cluster is set up, I used the Pulumi Kubernetes provider to deploy the cinder Helm chart to the cluster. You'll need to specify the correct chart version and any necessary values according to the Helm chart you are using.
    • At the end of the program, I'm exporting the kubeconfig necessary to connect to the cluster and the service endpoint for the deployed cinder service.

    Remember to replace the placeholder comments with the actual values suitable for your deployment, such as the cluster version, networking options, and any values required by the cinder Helm chart. You will also need to securely provide the kubeconfig data, possibly by retrieving it from Azure or another secure source.

    For the sake of completeness and best practices, you would actually retrieve the kubeconfig from the OpenShiftManagedCluster using output properties. However, that step is usually more involved and requires handling sensitive data, as it would likely involve interacting with Azure AD for authentication.

    Ensure that you have the required permissions and access to Azure and that your Pulumi stack is correctly configured to interact with your Azure account. You'll also need to install the Pulumi CLI, azure-native and kubernetes Pulumi packages. You can install these packages via npm:

    npm install @pulumi/pulumi @pulumi/azure-native @pulumi/kubernetes

    This sample should be taken as a starting point, and specific details should be filled in to match the requirements of your deployment environment and the cinder chart you're deploying.
