Deploy the twistlock-defender helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the Twistlock Defender Helm Chart on an AWS EKS Cluster using Pulumi, you would go through several steps. First, you'd need to create an EKS Cluster. For this, you can use the `eks.Cluster` Pulumi resource, which simplifies the process of setting up an EKS Cluster. After the cluster is set up, you'll need to deploy the Twistlock Defender Helm Chart to the cluster.

Here's an outline of the steps we will follow in our Pulumi program:

1. **Create an EKS Cluster**: Define an EKS cluster using `eks.Cluster` which will be used to host our Helm chart.
2. **Deploy the Helm Chart**: With the EKS cluster in place, we can proceed to deploy the Twistlock Defender Helm chart using the `kubernetes.helm.v3.Chart` resource.

I'll provide a TypeScript program that performs the above steps. This program assumes that you have AWS credentials configured for Pulumi and `kubectl` installed to interact with the cluster. Here's how you can achieve this:

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

// Step 1: Create an EKS cluster.
const cluster = new eks.Cluster('twistlock-eks-cluster', {
    desiredCapacity: 2,
    minSize: 1,
    maxSize: 2,
    instanceType: 't2.medium',
});

// Export the EKS cluster's kubeconfig.
export const kubeconfig = cluster.kubeconfig;

// Step 2: Deploy the Twistlock Defender Helm chart.
const chart = new k8s.helm.v3.Chart(
    'twistlock-defender',
    {
        chart: 'twistlock-defender', // Use the correct Helm chart name for Twistlock Defender.
        version: 'VERSION', // Specify the chart version you wish to deploy.
        fetchOpts: {
            repo: 'https://PATH_TO_HELM_REPO', // Specify the repository URL where the Helm chart is hosted.
        },
        // Add any configuration values here that your Twistlock Defender chart may need.
        values: {
            // Specify values needed for the Helm chart.
        },
    },
    { provider: cluster.provider }
);

// To interact with the resources, use `kubectl` with the kubeconfig from the output.
```

Remember to replace `VERSION` with the specific version of the Twistlock Defender Helm Chart you want to deploy and `https://PATH_TO_HELM_REPO` with the actual Helm repository URL. Moreover, the `values` object should be populated with the necessary values that the Twistlock Defender Helm chart requires. These values are typically documentation-specific.

The `eks.Cluster` resource simplifies creating an Amazon EKS cluster by abstracting away the underlying complexities ([EKS Cluster](https://www.pulumi.com/docs/reference/pkg/awsx/eks/cluster/)). The `kubernetes.helm.v3.Chart` resource is used to deploy Helm charts into a Kubernetes cluster ([Kubernetes Helm Chart](https://www.pulumi.com/docs/reference/pkg/kubernetes/helm/v3/chart/)).

By running this Pulumi program with `pulumi up`, you will set up a new EKS cluster and deploy the Twistlock Defender on it. After the deployment, you can manage your Kubernetes cluster using `kubectl` by configuring it with the kubeconfig file exported by the program.
