1. Deploy the query-exporter helm chart on Opensshift


    To deploy the query-exporter Helm chart on an OpenShift cluster using Pulumi, we will use the kubernetes package. This package allows us to deploy Helm charts among many other Kubernetes resources.

    To deploy a Helm chart, we will utilize the Chart resource from Pulumi's Kubernetes provider. The Chart resource is a high-level interface that encapsulates the management of Helm chart releases.

    Here's how you do it in TypeScript:

    1. Set up the Kubernetes provider: Before deploying the Helm chart, you need to ensure that the program is configured to target your OpenShift Kubernetes cluster. Typically, this involves setting up the kubeconfig file that allows Pulumi to authenticate and communicate with the cluster.

    2. Define the Helm Chart: You can define a Helm chart resource in Pulumi by specifying the chart's repository, name, and version, along with any configuration parameters required by the chart.

    3. Deploy the Chart: Once you define the chart, you can perform pulumi up to deploy resources on your OpenShift cluster.

    Here is a Pulumi program to deploy the query-exporter Helm chart on OpenShift:

    import * as k8s from '@pulumi/kubernetes'; // This will use the Kubernetes provider based on the kubeconfig from the current context, // which should point to your OpenShift cluster. Make sure you have this configured correctly. // Create a new instance of the `Chart` class to deploy the `query-exporter` Helm chart. const queryExporterChart = new k8s.helm.v3.Chart('query-exporter', { // The `chart` parameter specifies the name of the chart from the repository. chart: "query-exporter", // The `version` parameter specifies the version of the chart to deploy. version: "0.1.0", // Replace with the actual version you wish to deploy. // The `fetchOpts` parameter is used to specify the Helm repo containing the chart if it's not in the default Helm repo. fetchOpts: { repo: "https://charts.example.com/", // Replace with the actual Helm chart repository URL. }, // You can provide a `values` parameter to customize the chart's behavior. values: { // ... specify chart values here if needed }, // Define the OpenShift namespace where the chart should be installed. namespace: "default" // Replace with the target namespace for your Openshift cluster if necessary. }); // Export the base URL where the query-exporter is deployed to provide easy access after deployment. export const queryExporterUrl = "http://query-exporter.example.com"; // Change this to match your OpenShift's ingress configuration.

    Make sure to replace the repo and version placeholders with actual values that correspond to your query-exporter Helm chart information. Additionally, adjust the namespace and queryExporterUrl to align with your OpenShift environment.

    Once your Pulumi program is ready, deploy the chart to your OpenShift cluster with these steps:

    1. Open a terminal and navigate to the directory containing your Pulumi program.
    2. Run pulumi up which will preview the deployment. Review the proposed changes carefully.
    3. If you're satisfied with the preview, confirm the deployment by selecting yes.

    The Pulumi CLI will communicate with your cluster and deploy the query-exporter Helm chart according to the configuration specified in the program. Once completed, you can use the exported URL to interact with the query-exporter service on your OpenShift cluster.
