Deploy the portefaix-kyverno helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the Portefaix Kyverno Helm chart on Kubernetes using Pulumi, we will use the `kubernetes.helm.v3.Chart` resource. This resource represents a Helm chart, which is a package of pre-configured Kubernetes resources. Kyverno is a Kubernetes-native policy management tool, and by deploying the Portefaix Kyverno Helm chart, we're effectively installing Kyverno into our Kubernetes cluster with a pre-defined set of policies provided by Portefaix.

Here's the step-by-step process to achieve this:

1. **Setting up the Environment**: Ensure you have Pulumi CLI, kubectl, Helm, and access to a Kubernetes cluster configured.

2. **Importing Dependencies**: We'll import the necessary Pulumi and Kubernetes packages.

3. **Creating the Kubernetes Chart Resource**: Define the Helm chart from the Portefaix repository in our Pulumi program.

4. **Exporting Useful Information**: After deployment, we may want to export values such as the Kubernetes Namespace where the Helm chart is deployed.

Let's write the Pulumi program in TypeScript. Ensure you run `npm install` to fetch the required dependencies, including `@pulumi/kubernetes` which is the Kubernetes provider for Pulumi.

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

// Define the Portefaix Kyverno Helm chart.
const portefaixKyvernoChart = new k8s.helm.v3.Chart('portefaix-kyverno', {
    repo: 'portefaix', // Replace with the correct repository name if it differs.
    chart: 'kyverno', // The name of the chart in the repository.
    version: 'x.y.z', // Specify the version of the chart you want to deploy.
    // You may also specify other chart values as needed here. For example, `values: {}`
});

// Export the Kubernetes namespace where the chart is installed.
export const k8sNamespace = portefaixKyvernoChart.namespace;
```

Before running the program, replace `x.y.z` with the actual version of the Portefaix Kyverno Helm chart.

Running this Pulumi program will invoke Helm to deploy Kyverno with the Portefaix policies on your Kubernetes cluster. If you're using a custom values file, include it in the `values` property of the chart resource to override default configurations.

After running the program with `pulumi up`, the output will show you the changes that will be made to your cluster. Confirm the changes to proceed with the deployment. If successful, you will see the status of the resources created.

The `k8sNamespace` is an exported value that shows the namespace where Kyverno is deployed, which you can use to access or manage Kyverno resources after deployment.
