1. Deploy the ibm-glusterfs helm chart on Kubernetes

    TypeScript

    To deploy a Helm chart to a Kubernetes cluster using Pulumi, you can use the Chart resource from the @pulumi/kubernetes package. The Chart resource is a high-level component that enables you to deploy Helm charts from repositories or local paths.

    In the following TypeScript Pulumi program, I'll show you how to deploy the ibm-glusterfs Helm chart. Assuming you have already set up the Kubernetes cluster and configured Pulumi to use the right kubeconfig context, the following program will deploy ibm-glusterfs to your cluster.

    First, you'll need to install the necessary Pulumi package by running:

    npm install @pulumi/kubernetes

    Here is the program that will perform the deployment:

    import * as k8s from '@pulumi/kubernetes'; // Deploying the `ibm-glusterfs` Helm chart into a Kubernetes cluster. // Create a Kubernetes namespace for the `ibm-glusterfs` deployment. const namespace = new k8s.core.v1.Namespace("glusterfs-ns", { metadata: {name: "glusterfs"}, }); // Deploy `ibm-glusterfs` Helm chart from the Helm repository. const glusterfsChart = new k8s.helm.v3.Chart("glusterfs-chart", { namespace: namespace.metadata.name, chart: "ibm-glusterfs", version: "<CHART_VERSION>", // Specify the version of the chart you wish to deploy fetchOpts: { repo: "https://charts.bitnami.com/bitnami", // Use the helm repository where `ibm-glusterfs` is stored }, // Include any custom values you wish to override in the chart here. // For example: `values: { persistence: { size: "10Gi" } }` }, {dependsOn: namespace}); // Export the namespace name and Helm chart resources. export const glusterfsNamespace = namespace.metadata.name; export const glusterfsChartResources = glusterfsChart.resources;

    Replace <CHART_VERSION> with the specific version of the ibm-glusterfs chart that you want to deploy.

    This program does the following:

    1. It imports the necessary Pulumi Kubernetes SDK.
    2. It creates a new Kubernetes namespace called glusterfs where our Helm chart will be deployed. This is a best practice, helping to isolate our deployment.
    3. It then creates a Chart resource named glusterfs-chart using the Helm v3 API.
      • The namespace specifies where the chart will be deployed.
      • The chart is the name of the chart to deploy, in this case, ibm-glusterfs.
      • The version is where you specify the chart version.
      • The fetchOpts include the repository from which to fetch the chart. You should replace the repo URL with the actual repository URL containing the ibm-glusterfs chart.
    4. The values object within the Chart resource can be used to specify any configuration values that are specific to the ibm-glusterfs chart.
    5. It declares dependencies explicitly by using the dependsOn option, ensuring the namespace is created before the chart is deployed.
    6. It exports the namespace and chart resource details.

    Please note that the actual repo URL for ibm-glusterfs may differ; the provided URL https://charts.bitnami.com/bitnami is an example, and you will have to replace it with the valid repository URL.

    After writing this Pulumi program to a file (for example, index.ts), you can deploy the Helm chart to your cluster using the Pulumi CLI with the following commands:

    pulumi up

    Running pulumi up will initiate the deployment process where Pulumi performs a preview and then asks for confirmation before applying the changes. Once confirmed, it will deploy the ibm-glusterfs Helm chart to your Kubernetes cluster.
