Deploy the trusted-issuers-list helm chart on AWS EKS

Question

Pulumi · Accepted Answer

Deploying a Helm chart on an AWS EKS cluster can be broken down into several steps. Below is a detailed explanation of how to deploy the `trusted-issuers-list` Helm chart onto an AWS EKS cluster using Pulumi and TypeScript.

First, you need to set up your EKS cluster. Then you will install the Helm chart onto the cluster. The steps are:

1. **Create an EKS Cluster**: Define an EKS cluster resource with the necessary configurations.
2. **Deploy the Helm Chart**: After the cluster is up and running, you will deploy the desired Helm chart to the cluster.

To perform these actions using Pulumi, you will primarily use the `@pulumi/eks` package for creating the EKS cluster and the `@pulumi/kubernetes` package to deploy Helm charts.

Here is a TypeScript program that performs the above tasks. This program does not manage AWS credentials; it assumes that the Pulumi AWS provider has been configured with the necessary access to interact with your AWS account.

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

// Create an EKS cluster.
const cluster = new eks.Cluster("my-cluster", {
    // Specify the desired configuration for the EKS cluster here
    // e.g. number of nodes, node types, networking details, etc.
});

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

// Set up a Kubernetes provider using the cluster's kubeconfig.
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig,
});

// Deploy the `trusted-issuers-list` Helm chart onto the EKS cluster.
const helmChart = new k8s.helm.v3.Chart("trusted-issuers-list", {
    // Define the chart details here.
    chart: "trusted-issuers-list-chart-name", // You need to specify the actual chart name here.
    version: "chart-version", // Replace with the actual chart version.
    // Fetch the chart from a repository if necessary:
    // repo: "https://charts.example.com/",
    // Specify any values that you want to override from the default chart values.
    // values: {},
}, { provider: k8sProvider });

// Export any resources that may be useful to access your Helm deployment
// For instance, the URL to access a service provided by your Helm chart.
```

### Explanation:

- The EKS cluster is created using `new eks.Cluster`. The name "my-cluster" can be customized to any desired name. The configuration block must be populated with the specific details for your use case, such as the number of nodes, type, and networking details.

- The `kubeconfig` of the cluster is exported. This configuration file contains the necessary details to connect to your EKS cluster using tools like `kubectl`.

- A Kubernetes provider is instantiated using the kubeconfig which will be used to communicate with the EKS cluster.

- `new k8s.helm.v3.Chart` represents the Helm chart that you wish to deploy. Replace "trusted-issuers-list-chart-name" and "chart-version" with the actual Helm chart name and the desired version. If your chart is hosted in a Helm repository, the repo URL should be specified in `repo: "https://charts.example.com/"`.

The placeholders and comments in the above code need to be replaced with actual values specific to the Helm chart and EKS configuration you wish to use. After updating the placeholders and customizing the configuration, you would run `pulumi up` to execute the deployment. Pulumi will create the AWS EKS cluster and deploy the specified Helm chart into it.
