Deploy the nfs-provisioner helm chart on Opensshift

Question

Pulumi · Accepted Answer

Deploying an NFS Provisioner on OpenShift can be a convenient way to provision persistent volumes for your applications running in Kubernetes. Pulumi provides an easy way to deploy Helm charts to a Kubernetes cluster, including an OpenShift cluster.

Here's how you could deploy the nfs-provisioner Helm chart using Pulumi with TypeScript:

Set up OpenShift Cluster: Before deploying the Helm chart, make sure you have access to an OpenShift cluster and you are logged into it using oc.
Pulumi Project Setup: Ensure you have a Pulumi project set up and configured to use the correct Kubernetes context for your OpenShift cluster. If you haven't done this, the Pulumi documentation provides guidance on how to Create a Pulumi project.
Dependencies: You would need the @pulumi/kubernetes package to interact with Kubernetes using Pulumi.
Helm Chart Deployment: You'll deploy the nfs-provisioner Helm chart by defining a Pulumi Kubernetes Chart resource. You can specify the chart's name, the repository where the chart is hosted, and any values you want to override.

Below is the code that deploys the nfs-provisioner Helm chart to your OpenShift cluster:

import * as k8s from '@pulumi/kubernetes';

// Create an instance of the kubernetes provider connected to your OpenShift cluster.
const provider = new k8s.Provider('openshift-k8s', {
    // You should have your Kubernetes context configured for OpenShift in your kubeconfig file.
    // If you wish to specify a different context, you can pass it here.
    // context: "my-openshift-cluster-context",
});

// Deploy the nfs-provisioner using a Helm Chart.
const nfsProvisionerChart = new k8s.helm.v3.Chart('nfs-provisioner', {
    chart: 'nfs-provisioner',
    // Replace `<repository-url>` with the actual repository URL where the nfs-provisioner chart is located.
    // For example, if using the stable Helm repository, add it to your Helm repos with 'helm repo add'
    // and reference it here as 'stable/nfs-provisioner'.
    repositoryOpts: {
        repo: '<repository-url>',
    },
    // Specify the namespace where the NFS Provisioner will be deployed. The namespace should exist.
    // If not, you can create a namespace resource with Pulumi before this step.
    namespace: 'nfs',
    // Here you can specify values to override default chart values.
    // For `nfs-provisioner`, you may need to set specific values to tailor the deployment to your needs.
    values: {
        // Insert any values you want to override. Example:
        // storageClass: {
        //     defaultClass: true,
        // },
    },
}, { provider }); // Make sure to pass the provider to specify that this chart will be deployed in OpenShift.

// Exports a Kubernetes resource, such as the Helm chart.
export const helmChartName = nfsProvisionerChart.metadata.name;

This code creates a new instance of the Chart resource from the @pulumi/kubernetes/helm module. When you run this code using Pulumi, it will interact with your OpenShift Kubernetes cluster and create all necessary resources defined by the nfs-provisioner Helm chart.

Please replace the placeholder <repository-url> with the actual URL of the repository where the nfs-provisioner chart is hosted. If the chart is in a public repository, specify the name prefixed by the repository alias you have added to your local Helm configuration.

Running the above Pulumi program will deploy the NFS Provisioner to your OpenShift cluster. Make sure to review the official Helm chart for nfs-provisioner for any specific configuration values you need to override.
