Deploy the i2i5gcorehelm helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the `i2i5gcorehelm` Helm chart on AWS EKS, you would need to follow these steps:

1. Create an Amazon EKS cluster. This is a managed Kubernetes service that simplifies running Kubernetes on AWS without needing to install and operate your own Kubernetes control plane.
2. Configure the Kubernetes provider in Pulumi to connect to your EKS cluster.
3. Use Pulumi’s Kubernetes provider to deploy the Helm chart to your EKS cluster.

The following Pulumi program in TypeScript will demonstrate how to perform these steps. I'll include explanations throughout the code with comments to help you understand what each part is doing.

```typescript
import * as pulumi from '@pulumi/pulumi';
import * as aws from '@pulumi/aws';
import * as awsx from '@pulumi/awsx';
import * as k8s from '@pulumi/kubernetes';

// Step 1: Create an Amazon EKS cluster
// This uses the awsx package which provides higher level abstractions for AWS resources.
const cluster = new awsx.eks.Cluster('my-cluster', {
    // You can specify additional settings for the EKS cluster as needed.
    // For the sake of simplicity, this will create a small cluster with default configurations.
});

// Step 2: Configure the Kubernetes provider to connect to the EKS cluster
// The output properties of the created EKS cluster include kubeconfig,
// which is necessary for our Kubernetes provider to connect to the cluster.
const k8sProvider = new k8s.Provider('k8s-provider', {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Step 3: Deploy the Helm chart to the EKS cluster using the k8s provider
// This step assumes that the 'i2i5gcorehelm' Helm chart exists in a Helm chart repository.
const helmChart = new k8s.helm.v3.Chart('i2i5gcorehelm-chart', {
    chart: 'i2i5gcorehelm',
    // You can specify the Helm chart version, values, and other configurations here.
    // For now, I'll leave it with defaults, but you'll want to specify the appropriate values for your use case.
}, { provider: k8sProvider });

// Export the cluster's kubeconfig and endpoint so that you can interact with it using 'kubectl'
export const kubeconfig = cluster.kubeconfig;
export const clusterEndpoint = cluster.core.cluster.endpoint;

```

This program does the following:

- It first creates an EKS Cluster instance using `awsx`, which is a high-level component that makes it easier to create and manage an EKS cluster.
- It then sets up the Kubernetes provider by using the `kubeconfig` generated by the EKS cluster. This configuration allows Pulumi to communicate with your EKS cluster.
- Finally, it deploys the `i2i5gcorehelm` Helm chart to your EKS cluster. Note that the `chart` parameter should point to the actual name of your Helm chart as it exists in the Helm repository.

To run this program, save it as `index.ts` in a new Pulumi project directory. Run `pulumi up` to create the resources. Pulumi will provide you with a detailed preview of the resources that will be created and ask for confirmation before creating them.

After the deployment is successful, you can use the exported `kubeconfig` to interact with your Kubernetes cluster via `kubectl`.

Keep in mind that you need to have Helm charts available and properly configured in terms of dependencies and values passed. If your `i2i5gcorehelm` chart requires specific values, you should place them in an object like `{values: { myValue: "example" }}` within the `Chart` resource declaration.
