Deploy the csi-rclone helm chart on AWS EKS

Question

Pulumi · Accepted Answer

The task you want to accomplish is to deploy the `csi-rclone` Helm chart on an AWS Elastic Kubernetes Service (EKS) cluster using Pulumi. Follow these steps to build this infrastructure with Pulumi:

1. **Set up the EKS Cluster**: First, we will create an EKS cluster as the foundation for our Kubernetes workloads.
2. **Deploy the Helm Chart**: Once the cluster is in place, we will deploy the `csi-rclone` Helm chart to the EKS cluster.

For the purposes of this program, we will make some assumptions:
- We will use the default VPC and subnet settings, but you can customize these as needed.
- The `csi-rclone` Helm chart will be installed without any specific configuration options. However, in a real-world scenario, you would likely need to provide storage configuration that matches your use case.

Here is a Pulumi program written in TypeScript that accomplishes this:

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

// Step 1: Set up the EKS Cluster.
// We create a new EKS cluster with default settings.
// For more configuration options visit: https://www.pulumi.com/registry/packages/eks/api-docs/cluster/
const cluster = new eks.Cluster("my-cluster", {});

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

// Step 2: Deploy the csi-rclone Helm chart.
// We wait for the EKS cluster to be up and running by using the `provider` property,
// and then we use the k8s provider to deploy the csi-rclone Helm chart.
// Helm charts can be found at https://artifacthub.io/.
const rcloneChart = new k8s.helm.v3.Chart("csi-rclone", {
    chart: "csi-rclone",
    fetchOpts: {
        repo: "https://your-helm-chart-repository/", // Replace with the actual repository URL
    },
}, { provider: cluster.provider });

// Wait for the Helm chart to be ready before trying to interact with it.
export const rcloneChartReady = rcloneChart.status.isReady;

```

This program will:
- Create an EKS cluster with the `eks.Cluster` resource. Optionally, you can configure properties like the `minSize` or `maxSize` of your node group, or the version of Kubernetes you want to run.
- Use the `k8s.helm.v3.Chart` resource to deploy the `csi-rclone` Helm chart from a specified repository. It depends on the `cluster.provider` to ensure that the Helm chart is deployed only after the EKS cluster is ready.

Make sure to replace `"https://your-helm-chart-repository/"` with the actual Helm chart repository that contains `csi-rclone`.

After running this Pulumi program, you'll have a Kubernetes cluster running on AWS EKS along with the `csi-rclone` Helm chart deployed. You can interact with the cluster using the exported `kubeconfig`. The `rcloneChartReady` export can be used to programmatically ensure that your Helm chart is ready before performing any operations that depend on it.

To deploy the Pulumi program, simply execute it using the Pulumi CLI:

```sh
pulumi up
```

This CLI command will provision all resources defined in the program.
