Deploy the rclone-s3 helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the `rclone-s3` Helm chart on an AWS Elastic Kubernetes Service (EKS) cluster, you'll follow several steps:
1. You will create an EKS cluster.
2. You will configure your Pulumi environment to communicate with that EKS cluster.
3. You will deploy the Helm chart to EKS.

This guide assumes you have AWS credentials configured for Pulumi and `kubectl` configured to interact with your Kubernetes clusters.

First, install the Pulumi EKS package, which provides a high-level abstraction to create and manage an EKS cluster easily. For Helm charts deployment, you'll also need the Pulumi Kubernetes provider.

Here is the TypeScript program that demonstrates these steps:

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

// Step 1: Create an EKS cluster
// The `eks.Cluster` resource uses AWS CloudFormation to provision an EKS cluster.
const cluster = new eks.Cluster("my-eks-cluster", {
    desiredCapacity: 2,    // Specify the desired number of worker nodes
    minSize: 1,            // Specify the minimum number of worker nodes
    maxSize: 3,            // Specify the maximum number of worker nodes
    storageClasses: "gp2", // Define the default storage class as "gp2"
    deployDashboard: false, // Opt not to deploy the Kubernetes dashboard
});

// Export the kubeconfig so that the Kubernetes provider can use it to communicate with the EKS cluster
export const kubeconfig = cluster.kubeconfig;

// Step 2: Configure Pulumi to use your EKS kubeconfig
// The `k8s.Provider` resource informs Pulumi how to communicate with the EKS cluster
const provider = new k8s.Provider("provider", {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Step 3: Deploy the rclone-s3 Helm chart
// The `k8s.helm.v3.Chart` resource allows Pulumi to manage Helm chart deployments
const chart = new k8s.helm.v3.Chart("rclone-s3", {
    chart: "rclone-s3",
    version: "1.2.3", // Specify the version of the chart. Replace with your desired chart version
    fetchOpts: {
        repo: "http://charts.example.com/", // Replace with the Helm chart's repository URL
    },
}, { provider });

// Export any resources you would like to access externally
export const clusterName = cluster.eksCluster.name;
export const clusterEndpoint = cluster.eksCluster.endpoint;
```

This program will:
1. **Create an EKS cluster** with the specified number of worker nodes and the default storage class set to "gp2". Note that the EKS Dashboard is not deployed.
2. **Provide our EKS cluster's kubeconfig** to Pulumi's Kubernetes provider to manage the Kubernetes resources. This kubeconfig allows Pulumi to issue commands to our EKS cluster.
3. **Deploy the `rclone-s3` Helm chart** from its repository. You must replace `chart` with the name of the chart, `version` with the chart version, and `repo` with the URL of the Helm chart's repository.

After running this program with Pulumi CLI commands `pulumi up`, your EKS cluster will be provisioned and the `rclone-s3` Helm chart will be deployed to it.

Please replace `chart`, `version`, and `repo` with appropriate values for your specific `rclone-s3` Helm chart configuration. If you do not know the exact details of `rclone-s3` or the repository where it resides, you will need to obtain this information before running the program.
