1. Deploy the saml-exporter helm chart on Azure Managed Openshift Service


    To deploy the saml-exporter Helm chart on Azure Managed OpenShift Service using Pulumi, we'll follow these steps:

    1. Create an Azure OpenShift Managed Cluster.
    2. Deploy the Helm chart to the OpenShift cluster.

    Before proceeding, ensure that you have the Azure CLI installed and logged in to your Azure account, as Pulumi will use these credentials to provision resources.

    First, let's create an Azure OpenShift Managed Cluster. We'll use the azure-native.containerservice.OpenShiftManagedCluster resource for this purpose. When creating an OpenShift cluster in Azure, we must take care of several configurations, such as setting up the location, the network profile, the master and agent pool profiles, and authentication.

    Once the OpenShift cluster is up and running, we can proceed with deploying the saml-exporter Helm chart. We'll use the kubernetes.helm.v3.Chart resource from the kubernetes provider. This resource enables you to deploy a Helm chart into a Kubernetes cluster.

    Here's the TypeScript program that accomplishes these tasks:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create an Azure resource group const resourceGroup = new azure_native.resources.ResourceGroup("myResourceGroup", { location: "eastus", // Choose an Azure location }); // Create an Azure OpenShift Managed Cluster const openshiftManagedCluster = new azure_native.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", { location: resourceGroup.location, resourceName: "myOpenShiftCluster", resourceGroupName: resourceGroup.name, openShiftVersion: "v4.3", // Specify the OpenShift version networkProfile: { vnetCidr: "", }, masterPoolProfile: { count: 3, // Number of master nodes vmSize: "Standard_D4s_v3", // VM size of the master nodes }, agentPoolProfiles: [{ name: "agentpool", count: 3, // Number of agent nodes vmSize: "Standard_D4s_v3", // VM size of the agent nodes }], // Specify your authentication profile and identity providers as needed }); // The OpenShift Managed Cluster exposes a kubeconfig that we can use to configure the Kubernetes provider const openshiftKubeconfig = pulumi. all([openshiftManagedCluster.name, resourceGroup.name]). apply(([clusterName, rgName]) => { return azure_native.containerservice.listOpenShiftManagedClusterUserCredentials({ resourceName: clusterName, resourceGroupName: rgName, }); }).apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()); // Now, we create a Kubernetes provider with the kubeconfig from the OpenShift cluster const k8sProvider = new k8s.Provider("openshiftK8s", { kubeconfig: openshiftKubeconfig, }); // Next, deploy the saml-exporter Helm chart using the Kubernetes provider const samlExporterChart = new k8s.helm.v3.Chart("saml-exporter", { chart: "saml-exporter", // Replace with the correct chart name // Define the values or configurations for the Helm chart values: { // Chart-specific values here }, // Specify the namespace if needed namespace: "default", }, { provider: k8sProvider }); // Export the cluster endpoint export const clusterEndpoint = openshiftManagedCluster.publicHostname;

    This program completes the following:

    • It initializes a new Azure resource group.
    • Defines an Azure OpenShift Managed Cluster.
    • Retrieves the kubeconfig from the newly created OpenShift cluster.
    • Initializes a Pulumi Kubernetes provider using the retrieved kubeconfig.
    • Deploys the saml-exporter Helm chart into the OpenShift cluster using the Pulumi Kubernetes provider.

    Important notes:

    • Replace "saml-exporter" with the actual Helm chart name if it's different.
    • If your Helm chart requires specific values, replace the values: {} placeholder with your configuration.
    • The namespace is currently set to "default", but you may need to change this depending on your Helm chart's requirements or your organizational policies.
    • The openShiftVersion is a placeholder, and you should replace it with the version compatible with your needs.
    • VM sizes (Standard_D4s_v3) for master and agent nodes are examples. Choose a VM size that fits your workload requirements and budget.
    • Authentication profiles for the OpenShift cluster are not detailed in this sample. You must configure them according to your organization's security standards.

    After writing this program, save it in a *.ts file, and then use the Pulumi CLI to create the necessary resources by running the following commands in the directory where your file is located:

    pulumi up

    This command initiates the provisioning of resources specified in the program. Follow the prompts from the CLI to review and apply the changes.
