1. Deploy the velero-backup helm chart on Opensshift

    TypeScript

    To deploy the Velero Backup Helm chart on OpenShift, you need to use the Pulumi Kubernetes provider. The Chart resource from the Kubernetes package will be used to deploy a Helm chart. Here's a step-by-step guide and Pulumi program to achieve that.

    Explanation

    First, ensure you have Pulumi installed and configured with the necessary cloud provider (in this case, OpenShift). Next, you're going to write a TypeScript program that uses Pulumi's Kubernetes package to deploy a Helm chart.

    The kubernetes.helm.v3.Chart resource is a wrapper that allows you to deploy Helm charts into a Kubernetes cluster. This resource is suitable for OpenShift clusters as well since OpenShift is an extension of Kubernetes.

    In the Pulumi program below, make sure to replace placeholder values like <NAMESPACE>, <CHART-VERSION>, and <REPOSITORY-URL> with the actual values for your Velero Backup Helm chart. The Helm chart will be installed in the namespace you provide, so ensure that namespace exists in your OpenShift cluster.

    Here is the Pulumi program:

    import * as kubernetes from "@pulumi/kubernetes"; // Create a Kubernetes provider instance that targets your OpenShift cluster. const openshiftProvider = new kubernetes.Provider("openshift", { kubeconfig: "<KUBECONFIG_CONTENT>", }); // Deploy Velero Backup Helm chart using the Kubernetes provider. const veleroBackupChart = new kubernetes.helm.v3.Chart("velero-backup", { chart: "velero", version: "<CHART-VERSION>", // specify the chart version fetchOpts: { repo: "<REPOSITORY-URL>", // the repository where Velero Helm chart is located }, namespace: "<NAMESPACE>", // OpenShift namespace where you want to install Velero // Define any custom values you need for the Helm chart. values: { // ... define your custom values here }, }, { provider: openshiftProvider }); // Export any information about the deployed chart that you may need as outputs from your stack. export const veleroBackupChartName = veleroBackupChart.getResourceProperty("v1/Service", "velero-backup-velero", "metadata").apply(m => m.name);

    Replace <KUBECONFIG_CONTENT> with the content of your OpenShift kubeconfig file, <CHART-VERSION> with the version of Velero you wish to install, <REPOSITORY-URL> with the URL of the Helm repository that hosts the Velero chart, and <NAMESPACE> with the name of the namespace where you want to deploy Velero.

    Stack Outputs

    The export statement at the bottom is an example of how to export information from your stack. It exports the name of the service that belongs to the deployed Helm chart. You can add additional exports as needed to output other relevant information, such as endpoints or external IPs.

    Running the Program

    To run this program:

    1. Save the code to a file named index.ts.
    2. Run pulumi up to deploy the Helm chart to your OpenShift cluster.

    This program assumes you already have Pulumi CLI installed and have access to the OpenShift cluster with necessary permissions to deploy resources.

    Please note that for production scenarios or more complex setups, further customization of the Helm chart values or Kubernetes provider configuration might be necessary.
