Deploy the harbor-scanner-trivy helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy a Helm chart on an OpenShift cluster using Pulumi, you'll need to have access to an existing OpenShift cluster and have the appropriate permissions to deploy to it.

In the program below, I'm going to use the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider, which allows us to deploy Helm charts. If you haven't already installed the Pulumi Kubernetes provider, you will need to do so with the following command:

```bash
pulumi plugin install resource kubernetes v4.4.0
```

This resource will be used to deploy the Harbor Scanner Trivy Helm chart to your OpenShift cluster. The `Chart` resource requires a few input properties:
- `chart`: The name of the Helm chart you want to deploy.
- `version`: The version of the Helm chart you want to deploy (optional, if you want to deploy the latest version).
- `fetchOpts`: Contains options to specify the Helm chart repository (optional, if the chart is from the stable repository).
- `values`: A set of values to configure the Helm chart (optional).

Here's a Pulumi program in TypeScript that demonstrates how to deploy the Harbor Scanner Trivy Helm chart:

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

// Define the repository URL for the Helm chart.
const repoUrl = "https://helm.goharbor.io";

// Define the settings for the Trivy scanner Helm chart deployment.
const trivyScannerChart = new k8s.helm.v3.Chart("harbor-scanner-trivy", {
    chart: "harbor-scanner-trivy",
    version: "0.1.0", // replace with the desired chart version
    fetchOpts: {
        repo: repoUrl,
    },
    // You can specify namespace if needed, for instance, if you are operating on a namespace other than "default".
    namespace: "trivy-scanner-namespace", // replace with the desired namespace
    // Specify any additional values needed to configure the Trivy scanner here.
    values: {
        // This would be an example configuration that you can customize according to your needs.
        // service: {
        //   type: "LoadBalancer",
        // },
        // persistence: {
        //   enabled: true,
        //   storageClass: "standard", // specify your storage class
        //   size: "5Gi",
        // },
        // For other configurable values, check the chart's `values.yaml` or chart documentation.
    },
});

// Export any relevant resources, such as the URL to access the deployed application.
export const trivyScannerUrl = trivyScannerChart.getResourceProperty("v1/Service", "harbor-scanner-trivy", "status");

```

Remember this is a simplified example. The actual Helm chart values (`values: {}`) you will need depend on your specific use case and the Harbor Scanner Trivy Helm chart's configurable options, which are typically found in the `values.yaml` file in the Helm chart repository or documentation.

To perform this deployment, you would:
1. Set up Pulumi with your preferred cloud.
2. Create a new Pulumi project using `pulumi new`.
3. Write this code in `index.ts` within your Pulumi project.
4. Run `pulumi up` to preview and deploy the resources.

Should there be any specific configurations for your OpenShift cluster, you'll need to adapt the permissions and any specific settings, like custom security contexts or storage options, based on your cluster's configuration. Make sure to review the Helm chart's documentation for any OpenShift-specific considerations.
