1. Deploy the helm-csi-driver-nfs helm chart on Opensshift


    To deploy the helm-csi-driver-nfs Helm chart on OpenShift, we'll be using the kubernetes.helm.sh/v3.Chart resource from Pulumi's Kubernetes package. This resource allows you to deploy applications using Helm charts directly within your Kubernetes cluster, which, in this case, is an OpenShift cluster.

    Before we begin, make sure you have the following prerequisites set up:

    1. Pulumi CLI installed and configured.
    2. Access to an OpenShift cluster and configured kubectl to communicate with it.
    3. Helm chart details for the csi-driver-nfs Helm chart.

    The Pulumi Kubernetes provider uses the same configuration as kubectl for cluster access, so if you can access your cluster using kubectl, you should be able to deploy resources with Pulumi.

    Below is a TypeScript program that uses the Pulumi Kubernetes provider to deploy the helm-csi-driver-nfs Helm chart. The Chart resource type manages a set of Kubernetes resources as specified by a Helm chart.

    Here is the TypeScript code for deploying the chart:

    import * as k8s from "@pulumi/kubernetes"; const chartName = "csi-driver-nfs"; const chartRepo = "https://kubernetes-sigs.github.io/nfs-ganesha-server-and-external-provisioner/"; const chartVersion = "3.0.0"; // specify the chart version you want to deploy const namespace = "kube-system"; // specify the namespace where you want to deploy the chart const nfsChart = new k8s.helm.v3.Chart(chartName, { chart: chartName, version: chartVersion, fetchOpts: { repo: chartRepo, }, namespace: namespace, // If you need to provide custom values to the chart, you can include a 'values' object. values: { // specify any custom values here, for example: // storageClass: // archiveOnDelete: false }, }, { provider: k8sProvider }); // Export the chart's status to indicate whether it's ready. export const chartStatus = nfsChart.status;

    This program creates an instance of the Chart resource provided by the Pulumi Kubernetes package. It specifies the chart name, version, and repository.

    Also, notice the values object. This is where you would pass any configuration options that the NFS CSI driver chart accepts. In the code above, as an example, I've commented out how you could disable archiving of persistent volumes upon deletion, but this is just illustrative. Consult the chart's documentation for the correct values you should use.

    We've exported a chartStatus constant, which can give you information about the deployment status of your Helm chart. Once the program runs successfully, you can use the Pulumi CLI to check if the deployment was successful and if the resources are in the correct state.

    Remember to replace chartVersion, namespace, and any necessary values in the values object with the appropriate values for your use case.

    To deploy this program:

    1. Create a new directory, navigate into it, and run pulumi new kubernetes-typescript.
    2. Replace the content of index.ts with the code provided above.
    3. Run pulumi up to preview and deploy the changes.

    Pulumi will ask you to confirm the deployment by showing you the planned changes. If everything looks good, you can confirm, and Pulumi will deploy the Helm chart to your OpenShift cluster.
