Deploy the harbor-scanner-aqua helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `harbor-scanner-aqua` Helm chart on a Kubernetes cluster using Pulumi, you can use the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider. This allows you to install Helm charts as you would with the Helm CLI, while gaining the advantages of using infrastructure as code for managing the deployment.

Before proceeding with the deployment, ensure that you have:
1. Installed Pulumi CLI on your system.
2. Configured access to your Kubernetes cluster (typically by ensuring `~/.kube/config` is set up).

Below is a detailed Pulumi TypeScript program that declares a new Helm chart resource to deploy `harbor-scanner-aqua`.

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

// A new Helm Chart is instantiated to deploy harbor-scanner-aqua using the helm Chart resource.
// The `chart` parameter specifies the name of the chart, and `version` can be used to specify a specific chart version.
// You can provide custom values according to the chart's requirements through the `values` field, which maps to Helm's `--set` flag.
// `namespace` is optional and if not provided, it will be deployed to the 'default' namespace.

const harborScannerAquaChart = new k8s.helm.v3.Chart("harbor-scanner-aqua", {
    chart: "harbor-scanner-aqua",
    version: "1.0.0", // Specify the version of the chart you want to deploy
    // Add the repository where the chart can be found.
    fetchOpts: {
        repo: "https://your-helm-chart-repository", // Replace with the actual repository URL
    },
    values: {
        // Replace these with the actual values required for the harbor-scanner-aqua chart.
        // This is an example structure; the actual values will depend on harbor-scanner-aqua's values.yaml.
        image: {
            repository: "your-repo/harbor-scanner-aqua",
            tag: "your-tag",
        },
        service: {
            type: "ClusterIP",
            port: 8080,
        },
        // ... other configurable values ...
    },
}, { provider: k8sProvider });

// If a custom k8s provider must be used, it can be declared and used like so
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: "your-kubeconfig-string", // Contents of your kubeconfig file if not using the default location
});

// To access information about the deployed Chart, such as deployed resources,
// you can use the following output property.

export const harborScannerAquaResources = harborScannerAquaChart.resources;

```

This program sets up the necessary configurations to deploy a helm chart. Make sure you replace the placeholders like `"https://your-helm-chart-repository"` and others with the appropriate values for your use case.

You can run this program using the Pulumi CLI by navigating to the directory where this code is saved and running `pulumi up`. This will prompt Pulumi to preview the deployment and, upon confirmation, proceed to deploy the chart to your Kubernetes cluster.

Remember that for production-grade deployments, you'll need to pay closer attention to namespace management, resource constraints, security policies, and other Kubernetes best practices.
