Deploy the security-hub-bop-kratos-ui helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `security-hub-bop-kratos-ui` Helm chart on a Kubernetes cluster using Pulumi, we will be using the `@pulumi/kubernetes` package. This package allows us to work with Kubernetes resources, including those defined by Helm charts.

The Helm chart can be deployed using different Pulumi classes, but the most direct way is via the `Chart` class within the `helm.sh/v3` module. This class represents a Helm chart which can be installed into a Kubernetes cluster.

Below, you'll find a Pulumi program written in TypeScript that demonstrates how to deploy a Helm chart. This program assumes that you already have a Kubernetes cluster up and running, and that your `kubectl` is already configured to connect to it. The program does not cover the configuration of the Kubernetes cluster itself or the Helm chart repository as these are external to Pulumi.

Here is the detailed Pulumi TypeScript program that you can use to deploy the `security-hub-bop-kratos-ui` Helm chart to your cluster:

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

// Create an instance of the Helm chart to be deployed.
// We are creating it within the default namespace, but you can specify your namespace as needed.
const kratosUiChart = new k8s.helm.v3.Chart('kratos-ui', {
    repo: 'my-repo', // Replace with the name of the repository where the chart is located.
    chart: 'security-hub-bop-kratos-ui', // The name of the chart in the repository.
    version: '1.2.3', // The version of the chart you want to deploy.
    // values: {} // Optional values to override the chart values; provide your custom configuration here.
}, { provider: k8sProvider });

// Export the name of the deployed chart as output.
// This is useful if you want to confirm that your chart was deployed.
export const chartName = kratosUiChart.metadata.apply(metadata => metadata.name);

// To run this Pulumi program, you will execute the following commands in your terminal:
// 1. pulumi up -> To preview and deploy the changes.
// 2. pulumi stack output chartName -> To view the name of the deployed chart.
```

In this program, `kratosUiChart` is an instance of the `Chart` class. When a new `Chart` instance is created, Pulumi will ensure that the specified Helm chart is deployed to your Kubernetes cluster with the specified version and configuration values.

To run this program:

1. Ensure you have Pulumi CLI installed and set up.
2. Ensure you have Node.js and NPM installed to run the TypeScript program.
3. Save the above code in a file, e.g., `index.ts`.
4. Initialize a new Pulumi project in the same directory:
   ```
   pulumi new typescript
   ```
5. Install the necessary dependencies using npm:
   ```
   npm install @pulumi/pulumi @pulumi/kubernetes
   ```
6. Run `pulumi up` to preview and deploy the chart.
7. If satisfied with the preview, confirm the deployment to proceed.

Please note that you'll need to replace the placeholders (`my-repo`, `1.2.3`, and possibly `values`) with actual information corresponding to the Helm chart repository and desired chart version that you will use.

If you are using a private Helm repository, you may need to handle authentication details. You can pass additional options to the `Chart` resource to specify the Helm repository credentials.
