Deploy the kafka-connector helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy a Kafka Connector using Helm on Amazon EKS (Elastic Kubernetes Service), you'll need to have an EKS cluster already running. For this example, we'll use a high-level Pulumi component from the `@pulumi/eks` package to create a new EKS cluster, and then we will use the `@pulumi/kubernetes` package to deploy the Kafka Connector Helm chart onto that cluster.

Here's a step-by-step process:

1. **Create an EKS Cluster**: We'll set up an EKS cluster with the necessary configurations.
2. **Deploy a Helm Chart**: After establishing the cluster, we'll use Pulumi's Kubernetes provider to deploy the Kafka Connector Helm chart.

Below is a detailed Pulumi TypeScript program that performs these steps:

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

// Step 1: Create an EKS Cluster
// We create a new EKS cluster, which will provide us with the Kubernetes environment where our applications will run.
// The EKS cluster will include all the necessary resources like EC2 instances for worker nodes and networking setup.

const cluster = new eks.Cluster("my-cluster", {
    // Specify the desired settings for the EKS cluster
});

// Step 2: Deploy Kafka Connector Helm Chart
// After the cluster is ready, we'll set up a Kubernetes provider instance to connect to our new EKS cluster.
// We then use this provider to deploy resources, like Helm charts, to the cluster.

// Export the cluster's kubeconfig to connect to the Kubernetes cluster.
export const kubeconfig = cluster.kubeconfig;

// Create a new instance of the Kubernetes provider with the kubeconfig from the EKS cluster.
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: kubeconfig
});

// Deploy the Kafka Connector Helm chart using the Helm Chart resource from Pulumi's Kubernetes provider.
const kafkaConnectorChart = new k8s.helm.v3.Chart("kafka-connector", {
    chart: "kafka-connector", // Replace with the correct chart name if different
    // You can specify chart version, repository and other settings here.
}, { provider: k8sProvider });

// Export any necessary resources that were created, such as the Helm chart name or relevant endpoints.
export const kafkaConnectorChartName = kafkaConnectorChart.id;

// Note: If you are using a custom Helm repository, you will need to add the `repo` option in the ChartArgs,
// and you may also need to specify the `version` if you want to pin to a specific version of the Helm chart.
```

### Explanation:

- `eks.Cluster`: This resource defines and manages an EKS cluster on AWS.
- `k8s.Provider`: The Kubernetes provider for Pulumi allows you to manage Kubernetes resources with a kubeconfig obtained from the EKS cluster.
- `k8s.helm.v3.Chart`: This resource is used to deploy Helm charts into a Kubernetes cluster.

Make sure to replace the placeholder values in the `ChartArgs` with the correct details for the Kafka Connector Helm chart you wish to deploy. You'll need the chart name, and potentially the repository URL and chart version.

After deploying this Pulumi program using `pulumi up`, the command will execute the steps described, and you'll have a Kafka Connector running in your EKS cluster ready for use.

Keep in mind that EKS clusters can incur costs in your AWS account, so after finishing your work, you should cleanup your resources with `pulumi destroy` if they are no longer needed.
