Deploy the termbox helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the termbox Helm chart on an AWS EKS cluster using Pulumi, we'll proceed with the following steps:

1. **Set up an EKS Cluster**: We'll create an EKS Cluster which is a managed Kubernetes service provided by AWS which lets you run Kubernetes without having to install, operate, or maintain your own Kubernetes control plane or nodes.

2. **Deploy Helm Chart**: Once we have our cluster set up, we'll use Pulumi's Kubernetes provider to deploy the termbox Helm chart to our EKS cluster.

The code below showcases how you can accomplish this using Pulumi with TypeScript.

Note: Make sure you have your AWS credentials configured in your environment for Pulumi to use.

Here is the TypeScript program to deploy a termbox Helm chart on EKS:

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

// Create an EKS cluster
const cluster = new eks.Cluster("my-cluster", {
    // Specify the desired settings for the cluster, for example:

// Number of cluster nodes
    desiredCapacity: 2,
    minSize: 1,
    maxSize: 3,

// Worker node settings
    instanceType: "t2.medium",

// Kubernetes version
    version: "1.21"
});

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

// Use Pulumi's Kubernetes provider to connect to the EKS Kubeconfig.
const provider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Deploy the termbox Helm chart to the EKS cluster
const termboxChart = new k8s.helm.v3.Chart("termbox", {
    chart: "termbox",
    // You can specify the exact chart version to use, if known
    // version: "1.2.3",
    
    // If the chart is from a custom Helm repo, provide the `repo` URL
    // repo: "https://my-helm-repo.org/charts",

// Override default values by specifying your custom values
    values: {
        // ... insert your custom values here
    },
}, { provider });

// Optional: Export any of the resources' properties if needed.
// For example, you may want to export the endpoint to access the termbox application
export const termboxEndpoint = pulumi.interpolate`http://${termboxChart.getResourceProperty("v1/Service", "termbox", "status").apply(s => s.loadBalancer.ingress[0].ip)}`;

```

This program assumes that the termbox Helm chart is publicly available in the default Helm chart repositories. If it's in a custom repository, you would need to specify the `repo` field with the URL of the repository.

The `termboxChart` will create the Helm release using the Kubernetes provider which is configured to communicate with the EKS cluster that was created earlier (`my-cluster`). It will also apply any custom values you want to override in the Helm chart through the `values` field.

Lastly, we export the `kubeconfig` so that you can interact with your cluster using `kubectl` from your local machine. We've also shown how you could export other outputs from the stack, such as the endpoint of a service deployed by the Helm chart, though the specific resources and their properties will depend on the details of the Helm chart.

**Important**: Please replace placeholders like the number of nodes, instance type, or custom values as per your requirements before running the program.
