Deploy the gcpdisk-csi-driver helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `gcpdisk-csi-driver` Helm chart on Kubernetes using Pulumi, you will need to have your Kubernetes cluster already set up and configured to be managed by Pulumi. The Pulumi Kubernetes Provider will use your `kubeconfig` file to connect to the Kubernetes cluster.

The `gcpdisk-csi-driver` Helm chart will deploy the Google Compute Engine Persistent Disk CSI (Container Storage Interface) driver. This is necessary for your Kubernetes cluster to interact with GCP's disk storage resources. The CSI driver allows Kubernetes to understand how to create, format, mount, and manage lifecycle operations on GCP persistent disks.

To accomplish this, you will use the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider. This resource allows you to deploy Helm charts into your Kubernetes cluster through Pulumi.

Here is a program that will deploy the `gcpdisk-csi-driver` Helm chart:

```typescript
import * as kubernetes from "@pulumi/kubernetes";

// Define the namespace where the helm chart will be installed.
const namespace = new kubernetes.core.v1.Namespace("gcpdisk-csi-driver-ns", {
    metadata: { name: "gcpdisk-csi" }
});

// Deploy the gcpdisk-csi-driver Helm chart into the Kubernetes cluster.
const gcpdiskCsiDriverChart = new kubernetes.helm.v3.Chart("gcpdisk-csi-driver", {
    // Specify the chart repository URL and the chart name.
    repo: "gke-release",
    chart: "gcp-compute-persistent-disk-csi-driver",
    version: "1.2.3", // Use the appropriate chart version.
    namespace: namespace.metadata.name,
    // Specify the values for the Helm chart. Replace this with any custom
    // configurations you need. For default installation, you can skip 'values'.
    values: {
        // Custom values for the Helm chart can be specified here.
        // E.g. to change the storage class parameters:
        // storageClass: {
        //   parameters: {
        //     type: "pd-ssd"
        //   }
        // }
    },
}, { provider: myK8sProvider }); // Ensure you use the correct Kubernetes provider.

// Export the namespace name and the Helm release status.
export const namespaceName = namespace.metadata.name;
export const gcpdiskCsiDriverChartStatus = gcpdiskCsiDriverChart.status;
```

Before running this Pulumi program, make sure you replace the `version` with the correct version of your Helm chart. Also, adjust the `values` field if you need to customize the Helm chart's values. The `myK8sProvider` should be replaced with a reference to your configured Kubernetes provider if you are not using the default one.

For the current program, the `gcpdisk-csi-driver` Helm chart is installed within a new Kubernetes namespace called `gcpdisk-csi`. You can modify the namespace according to your organization's conventions.

To run this program, you will need to have Node.js installed, and then you can use the following commands within the directory where you have your Pulumi code:

1. Install Pulumi CLI and login to the Pulumi Service.
2. Install the necessary NPM packages:

```bash
npm install @pulumi/kubernetes
```

3. Run `pulumi up` to preview and deploy the changes:

```bash
pulumi up
```

After successfully executing the Pulumi program, the `gcpdisk-csi-driver` will be deployed in your Kubernetes cluster, and you will be able to start using GCP persistent disks in your Kubernetes workloads.
