Deploy the tsorage helm chart on Opensshift

Question

Pulumi · Accepted Answer

Deploying a Helm chart on OpenShift using Pulumi involves several steps. Below, I provide a comprehensive explanation and a TypeScript program using the `kubernetes` package, which you'll need to install using `npm` or `yarn`.

Here are the key components of the program:

1. **Provider setup**: We need to configure the Kubernetes provider to interact with your OpenShift cluster. You are expected to have `kubectl` configured to point to your OpenShift cluster, as Pulumi leverages the existing kubeconfig file.

2. **Chart Resource**: In Pulumi, a Helm chart is represented by the `kubernetes.helm.v3.Chart` resource. This resource will install a Helm chart onto your Kubernetes cluster.

Remember, Pulumi programs are executed with the Pulumi CLI, which needs to be installed and logged in to a Pulumi account. You'll also need to have access to your OpenShift cluster configuration accessible through `kubectl`.

Here's a TypeScript program that defines the necessary resources to deploy the "tsorage" Helm chart onto an OpenShift cluster:

```typescript
import * as k8s from "@pulumi/kubernetes";

// Assumes that you have your OpenShift kubeconfig file configured.
const kubeconfig = process.env.KUBECONFIG;

// Create a Kubernetes provider instance with access to your OpenShift cluster.
const provider = new k8s.Provider("openshift-provider", { kubeconfig });

// Define the Helm chart for Tsorage. 
// Replace `chartRepoUrl` with the repository URL where your chart exists.
// Replace `chartVersion` with the specific chart version you wish to deploy.
const chart = new k8s.helm.v3.Chart("tsorage-chart", {
    chart: "tsorage", // The name of the chart. Adjust if the chart name is different.
    version: "chartVersion", // specify the chart version
    fetchOpts: {
        repo: "chartRepoUrl", // the repository URL of the chart
    },
    // You can include custom values for the chart by setting the `values` property.
    values: {
        // Set custom values for the Helm chart here if needed.
    },
}, { provider });

// Exports: Add any necessary outputs that you might want to access.
// For example, if your Helm chart provisions a service of type LoadBalancer,
// you might want to export its endpoint.
export const chartName = chart.metadata.apply(m => m.name);
```

Replace `"chartVersion"`, `"chartRepoUrl"`, and any values in the `values` object with actual values for your chart. After you've adjusted the program with actual values and saved it to a `.ts` file, you should run `pulumi up` to provision the resources on your cluster.

This program will install the "tsorage" Helm chart onto the OpenShift cluster configured in your `kubeconfig`, and you can track the progress and output in your terminal. If the chart provides any resources that become publicly accessible (like a URL), those can be exported and will be printed out as well after the deployment completes.
