Deploy the cluster-api-provider-hetzner helm chart on AWS EKS

Question

Pulumi · Accepted Answer

In order to deploy the `cluster-api-provider-hetzner` helm chart on an Amazon EKS (Elastic Kubernetes Service) cluster using Pulumi, you will need to follow these steps:

1. Set up an EKS cluster: This involves creating the EKS cluster and its needed components such as the node groups.
2. Deploy the helm chart on the cluster: After the EKS cluster is up and running, use the Pulumi Kubernetes provider to deploy the helm chart.

Below is a Pulumi program written in TypeScript that will create an EKS cluster and deploy the `cluster-api-provider-hetzner` helm chart to it. The program uses `@pulumi/eks` and `@pulumi/kubernetes` libraries to accomplish this task.

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

// Step 1: Create an EKS Cluster
// We create a new EKS cluster with default settings; the specifics can be customized as per need.
const cluster = new eks.Cluster("my-cluster", {});

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

// Step 2: Deploy the helm chart on the EKS cluster
// This assumes that the `cluster-api-provider-hetzner` chart is available in a public or private helm repository.
// We specify the name of the Helm chart, the version, and the repository URL.
const chart = new k8s.helm.v3.Chart("hetzner-provider", {
    chart: "cluster-api-provider-hetzner",
    version: "0.1.0", // Replace with the actual chart version
    fetchOpts: {
        repo: "https://charts.example.com/", // Replace with the actual chart repository URL
    },
}, { provider: cluster.provider }); // Ensure that the helm chart is installed using the EKS cluster's provider

// Note that since the specific chart and version details are not provided,
// you will need to replace the `version` and `fetchOpts.repo` with the actual details from the chart's repository.
```

In this program, we first create an EKS cluster using `@pulumi/eks`. By default, this creates an EKS cluster with all the required components such as VPC, subnets, and node groups with reasonable defaults. If you need to customize the VPC, subnets, or the node group properties, you can pass those as arguments to the `eks.Cluster` constructor.

We then export the generated kubeconfig, which can be used to access the cluster with kubectl or other Kubernetes management tools.

Next, we deploy the `cluster-api-provider-hetzner` Helm chart onto our EKS cluster using the `@pulumi/kubernetes` library. Here, you need to replace the `version` and `repo` properties in `fetchOpts` with the correct chart version and Helm repository URL.

Remember to replace `'https://charts.example.com/'` with the actual Helm chart repository that hosts the `cluster-api-provider-hetzner` chart. Also, the provided `version` should match the chart version you intend to deploy. If you are using a private repository, additional configurations such as authentication credentials may be needed.

After configuring the Pulumi program with the correct values, you can deploy your infrastructure by running `pulumi up`. This will provision the EKS cluster and deploy the helm chart on it.
