Deploy the twistlock-defender helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the Twistlock Defender Helm chart on the Digital Ocean Kubernetes Service using Pulumi, we will take the following steps:

1. **Create a Kubernetes cluster on Digital Ocean:** Define a Kubernetes cluster resource which will be our target cluster for deploying the Helm chart.

2. **Deploy the Helm Chart:** Define a Helm chart resource, pointing to our previously created Kubernetes cluster, and using the details for the Twistlock Defender Helm chart.

Now, let's dive into the program. Ensure you have Pulumi installed and setup with access to your Digital Ocean account. You'll also need to have the Pulumi Digital Ocean provider and the Kubernetes provider configured.

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

// Step 1: Create a new Digital Ocean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: digitalocean.Regions.NYC1, // Select the appropriate region
    version: "1.21.5-do.0", // Use a specific version of Kubernetes
    nodePool: {
        name: "worker-pool",
        size: digitalocean.DropletSlugs.DropletS2VCPU2GB, // Choose the right size for your workload
        nodeCount: 2, // Set the number of nodes in your pool
    },
});

// Step 2: Deploy the Twistlock Defender Helm chart to the Digital Ocean cluster
const twistlockDefenderChart = new k8s.helm.v3.Chart("twistlock-defender", {
    chart: "twistlock-defender", // The name of the chart
    version: "1.0.0", // Specify the version of the chart you want to deploy
    fetchOpts: {
        repo: "https://your-repo-containing-twistlock-defender/", // Replace with the chart's repository URL
    },
    // You may need to specify the values based on your requirements or Twistlock Defender configuration
    values: {
        // example values, these will need to be replaced with actual configuration values
        twistlock_console: {
            hostname: "twistlock-console.example.com",
            username: "admin",
            password: "examplePassword",
        },
    },
}, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig }) });

// Export the cluster endpoint to access the Twistlock Defender Web UI
export const clusterEndpoint = cluster.endpoint;

// Export the kubeconfig for direct access to the cluster with kubectl
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;
```

This Pulumi program has two major parts:

1. We create a `KubernetesCluster` resource using the `@pulumi/digitalocean` package. This represents your cluster on the Digital Ocean platform. Replace the `region` and `version` parameters with the values that are appropriate for your specific use case.

2. We then define a `Chart` resource using the `@pulumi/kubernetes` package which allows us to deploy Helm charts. We specify the chart name `twistlock-defender` here assuming that's the name in the repository which you must replace with the actual repository and chart details where the Twistlock Defender Helm chart is hosted.

Please note that you need to specify the actual values for the Twistlock Defender chart configuration based on your installation requirements. The `fetchOpts.repo` option should be set to the repository URL where the Twistlock Defender chart is hosted.

At the end of the program, we are exporting the `cluster.endpoint` and `kubeConfigs.rawConfig` which can be used to interact with your Kubernetes cluster, such as accessing the Twistlock Defender Web UI or using `kubectl` respectively.

To deploy this configuration, save the code to a `.ts` file, and then run:

```bash
pulumi up
```

This command will prompt you to confirm the deployment after showing you the planned changes. Once confirmed, Pulumi will execute the necessary steps to create the Digital Ocean Kubernetes cluster and deploy the Twistlock Defender Helm chart to it.

Remember to replace placeholder values like your Twistlock Chart version and configuration in the `values` property to match actual configuration details required for your Twistlock Defender setup.
