Deploy the secrets-store-csi-driver-provider-gcp helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the `secrets-store-csi-driver-provider-gcp` Helm chart on OpenShift using Pulumi, we would use the Pulumi Kubernetes provider. The provider enables us to manage Kubernetes resources, including deploying Helm charts.

Below is a Pulumi program written in TypeScript that demonstrates how you can define the necessary resources to deploy the `secrets-store-csi-driver-provider-gcp` Helm chart.

The program will assume that you have your OpenShift and Pulumi configurations already set up. The Kubernetes provider will use your kubeconfig file to interact with your OpenShift cluster.

Before we take a deep dive into the Pulumi code, I'll explain the key steps that we'll be taking within our program:
1. We will import the necessary modules from Pulumi and other TypeScript modules.
2. We will create a Kubernetes provider instance that is configured for OpenShift.
3. We will use the `helm.v3.Chart` class from the Pulumi Kubernetes provider to deploy the Helm chart.

Now let's take a look at the Pulumi program:

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

// Create an instance of the Kubernetes Provider configured for OpenShift
const openshiftProvider = new kubernetes.Provider("openshiftProvider", {
    // Assuming kubeconfig is set in the environment or default location
});

// Define the Helm chart for the secrets-store-csi-driver-provider-gcp
const csiDriverProviderGcpChart = new kubernetes.helm.v3.Chart("csi-driver-provider-gcp", {
    chart: "secrets-store-csi-driver-provider-gcp",
    version: "0.1.0", // Specify the version of the Helm chart you wish to deploy
    fetchOpts: {
        repo: "https://your-helm-chart-repository", // Replace with the actual Helm chart repository URL
    },
}, { provider: openshiftProvider });

// Export the resources created for the Helm chart deployment
export const csiDriverProviderGcpChartResources = csiDriverProviderGcpChart.resources;
```

Here's what each part of this program does:
- We begin by importing the `@pulumi/pulumi` and `@pulumi/kubernetes` packages.
- A Kubernetes provider for OpenShift is instantiated, which will use the configuration of Kubernetes cluster specified in your environment.
- We then declare a Helm chart resource which references the `secrets-store-csi-driver-provider-gcp` Helm chart. The `chart` property specifies the Helm chart that you wish to install, and the `version` property can be adjusted to match the specific version of the Helm chart you require. The `fetchOpts.repo` should be replaced with the URL of the Helm chart repository where the `secrets-store-csi-driver-provider-gcp` chart is hosted.
- Finally, we export the chart resources that Pulumi will create as part of deploying the Helm chart. This allows you to see all of the Kubernetes resources that are created by the Helm chart in your Pulumi stack's output.

Once you have set up this program, you can run it using standard Pulumi CLI commands:

1. First, initialize a new Pulumi project if you haven't already.
    ```
    pulumi new typescript
    ```
   
2. Replace the contents of `index.ts` with the TypeScript code provided above.

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

Pulumi will preview the changes and show you what will be deployed. If everything looks good, you can confirm the deployment, and Pulumi will execute the actions necessary to deploy the `secrets-store-csi-driver-provider-gcp` Helm chart on your OpenShift cluster.

Please note, Helm charts often have configurations that you can modify through values. If you wish to customize your deployment, you can pass a `values` parameter to the Chart resource. This parameter is an object where you can specify configuration options that are available for that Helm chart.
