Deploy the os-ubuntu helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the `os-ubuntu` Helm chart on AWS EKS using Pulumi, you will first need to create an EKS cluster and then deploy the chart to the cluster. The following Pulumi TypeScript program demonstrates these steps:

1. Set up an EKS cluster using the `eks.Cluster` resource from the Pulumi EKS package.
2. Deploy the `os-ubuntu` Helm chart to the EKS cluster using the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider.

Before you start, make sure you have Pulumi CLI installed and configured with AWS credentials, along with `kubectl` and the AWS CLI for interacting with your cluster post-deployment.

Now, let's break down the steps in the Pulumi TypeScript program:

### EKS Cluster Creation

First, we'll create an EKS cluster. The `eks.Cluster` resource automatically provisions and configures the necessary AWS resources, like EC2 instances, the EKS service role, and the VPC configuration.

### Helm Chart Deployment

Once the cluster is up and running, we'll deploy the `os-ubuntu` Helm chart. If the Helm chart requires specific values, you can provide them in the `values` property of the `Chart` resource.

Note that the actual `os-ubuntu` Helm chart needs to be in a Helm repository or available locally for this code to work. Replace the chart name with the actual name if it differs.

Here's the complete program:

```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";

// Create an EKS cluster with the default configuration.
const cluster = new eks.Cluster("myCluster", {
    // If needed, you can customize your cluster configuration:
    // nodeType: "t2.medium",
    // desiredCapacity: 2,
    // minSize: 1,
    // maxSize: 2,
    // storageClasses: "gp2",
    // deployDashboard: false,
});

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

// Deploy the os-ubuntu Helm chart to the EKS cluster.
const osUbuntuChart = new k8s.helm.v3.Chart("os-ubuntu", {
    chart: "os-ubuntu", // This is a placeholder value; replace with your actual Helm chart name.
    // If the Helm chart is not in the stable repository or a local chart, specify the 'repo' attribute.
    // For example: repo: "http://my-charts.example.com/"
    // Values can be specified to customize the Helm chart behaviour.
    // values: {
    //     key: "value"
    // },
}, { provider: cluster.provider });

// Optional: Export the Helm chart resources.
export const helmResources = osUbuntuChart.resources;
```

After deployment, you will have an EKS cluster running with the `os-ubuntu` Helm chart deployed. The `kubeconfig` output can be used to interact with your Kubernetes cluster with `kubectl`. The specific details provided in the comments can be adjusted as per your requirements and the specifics of the `os-ubuntu` Helm chart.
