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


    To deploy the oracledb-exporter Helm chart on an Azure Managed OpenShift service using Pulumi, you will first need to set up an OpenShift Managed Cluster in Azure, and then deploy the Helm chart to the cluster.

    I will guide you through the steps:

    1. Create an Azure Managed OpenShift cluster: This involves defining a managed OpenShift cluster resource using the Pulumi Azure Native provider. OpenShift clusters are Kubernetes clusters with additional features and security provided by Red Hat.

    2. Deploy the oracledb-exporter Helm chart to the cluster: Helm charts help define, install, and upgrade complex Kubernetes applications. In Pulumi, you can deploy a Helm chart using the Chart resource from the Kubernetes provider.

    Here is the Pulumi TypeScript program that accomplishes the deployment:

    import * as pulumi from "@pulumi/pulumi"; import * as azureNative from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an Azure Managed OpenShift Cluster const resourceGroupName = new azureNative.resources.ResourceGroup("myResourceGroup", { location: "East US", // Select the appropriate Azure region }); const openshiftCluster = new azureNative.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", { resourceGroupName: resourceGroupName.name, location: resourceGroupName.location, openShiftVersion: "v3.11", // Specify your desired OpenShift version // Add other required properties (like network profile, master and agent pool profiles) as needed. // The configuration may vary depending on the Azure region and your specific requirements. }); // Step 2: Deploy the `oracledb-exporter` Helm chart to the cluster // Ensure that the K8s provider instance uses the kubeconfig credentials from the newly created OpenShift cluster. const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: openshiftCluster.kubeconfig.apply(kubeconfig => kubeconfig.rawData), }); const oracledbExporterChart = new k8s.helm.sh.v3.Chart("oracledb-exporter", { chart: "oracledb-exporter", version: "0.1.0", // Replace with the specific chart version you intend to deploy fetchOpts: { repo: "https://helm-repo-url.com/charts", // Replace with the URL of the chart repository hosting the oracledb-exporter chart }, // Define any custom values for the Helm chart deployment (e.g., database connection details) values: { "datasource": { "host": "my-oracledb.host", // Replace with your Oracle DB host information "port": 1521, "database": "mydatabase", // Replace with your specific database name "user": "username", // Replace with your database username "password": "password", // Replace with your database password }, // ... include additional customization as required }, }, { provider: k8sProvider }); // Export the endpoint of the OpenShift cluster export const clusterEndpoint = openshiftCluster.openShiftApiServerUrl;

    Before running this program with Pulumi, make sure:

    • You have set up the Azure Provider with the appropriate credentials.
    • You have installed Pulumi CLI and configured it for use with Azure.
    • You have the @pulumi/azure-native and @pulumi/kubernetes packages installed in your project.

    The program starts by creating a resource group, followed by the creation of the OpenShift Managed cluster. It specifies the location and version for the cluster. The openShiftVersion and other configurations like networkProfile, masterPoolProfile, and agentPoolProfiles will need to be set according to your requirements.

    Next, we create a Pulumi Kubernetes provider pointing to the new OpenShift cluster by using the kubeconfig provided by the cluster's output. Using this provider, we deploy the oracledb-exporter Helm chart, specifying the chart version and repository URL where the Helm chart is stored.

    Finally, the program exports the endpoint to access the OpenShift cluster API server. This allows us to interact with the cluster.

    Run this program using the Pulumi CLI with the following commands:

    pulumi stack init dev pulumi up

    This will provision the required cloud resources with Azure and deploy your Helm chart to the cluster.
