1. Deploy the simple-grafana helm chart on Opensshift

    TypeScript

    To deploy the simple-grafana Helm chart on OpenShift using Pulumi, you would typically:

    1. Set up access to your OpenShift cluster in Pulumi.
    2. Use the @pulumi/kubernetes package to create a Helm Release resource that points to the simple-grafana chart.

    Here's a detailed explanation of the steps followed by the Pulumi program written in TypeScript:

    Prerequisites:

    • Install Pulumi CLI and set it up for use.
    • Configure kubectl to connect to your OpenShift cluster.

    Steps:

    1. Setting Up Your Pulumi Project: You'd start by creating a new Pulumi project or navigating to an existing one.

    2. Adding Dependencies: You would ensure that the @pulumi/kubernetes package is added to your project to interact with the Kubernetes API.

    3. Writing the Pulumi Program:

      • Import the necessary libraries.
      • Create a kubernetes.helm.v3.Chart resource that represents your Helm deployment.
      • Specify the Helm chart name, in this case, "simple-grafana" and the other details such as repository, chart version, release name, and any specific configurations if needed.
      • If you need to pass custom values to the Helm chart, they can be specified in the values property.

    4. Deploying Your Chart:

      • You'll run pulumi up to preview and deploy your changes.
      • Upon a successful deployment, Pulumi will ensure that the simple-grafana Helm chart is deployed onto your OpenShift cluster.

    Here is the complete program that does this:

    import * as k8s from '@pulumi/kubernetes'; // Initialize a new or existing Pulumi project using your kubeconfig credentials. const provider = new k8s.Provider('openshift-provider', { kubeconfig: process.env.KUBECONFIG, // Ensure that your KUBECONFIG environment variable is set. }); // Deploy the simple-grafana Helm chart using Pulumi's Kubernetes provider. const grafanaChart = new k8s.helm.v3.Chart('simple-grafana', { chart: 'grafana', // The name of the chart version: '6.1.14', // The version of the chart fetchOpts: { repo: 'https://grafana.github.io/helm-charts', // Helm repository URL }, // Set the values for the Helm chart values: { // For example, to set the admin password you would add: // adminPassword: 'your-admin-password', // Any other Grafana Helm chart values can be set here in the values object. }, }, { provider: provider }); // Export the URL of the Grafana instance // You need to know the service name and namespace to construct the URL. export const grafanaUrl = `http://simple-grafana.<namespace>.svc.cluster.local`; // Replace <namespace> with your actual namespace

    Run this program using the pulumi up command, which will provision the resources on your OpenShift cluster according to the configuration defined in the chart.

    Notes:

    • You may need to customize the values and version to match your requirements.
    • Make sure to replace <namespace> with your actual namespace where the Grafana instance will be accessible.
    • Check the Helm chart documentation for the exact configurable values: grafana.

    By following these steps and running this TypeScript program using the Pulumi CLI, you will be able to deploy the simple-grafana Helm chart on your OpenShift Cluster.
