Deploy the matrix-dimension helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the `matrix-dimension` Helm chart on an AWS EKS cluster, we'll go through the following steps:

1. Set up an EKS cluster using Pulumi's EKS package.
2. Create an ECR repository to store container images if needed.
3. Deploy the Helm chart to the EKS cluster.

First, we will need to create an EKS cluster. AWS EKS is a managed Kubernetes service that makes it easier for you to run Kubernetes on AWS without needing to install and operate your own Kubernetes control plane. We'll utilize the `eks.Cluster` resource for this.

Then, if your Helm chart requires you to have a Docker image hosted in AWS ECR (Elastic Container Registry), we will set up an ECR repository using `aws.ecr.Repository`.

Lastly, we'll deploy the Helm chart using the `kubernetes.helm.sh/v3.Chart` resource which allows you to deploy Helm charts in a Kubernetes cluster.

Here's a TypeScript program that accomplishes these steps:

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

// Assuming Pulumi is already configured with AWS credentials and region.

// Step 1: Create an EKS cluster
const cluster = new eks.Cluster("my-cluster", {
    desiredCapacity: 2,
    minSize: 1,
    maxSize: 2,
    // Specify other properties according to your requirements
});

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

// Step 2: Create an ECR repository (if your Helm chart requires private images)
const repo = new aws.ecr.Repository("my-repo");

// Export the repository URL to push your container images.
export const repositoryUrl = repo.repositoryUrl;

// Step 3: Deploy the matrix-dimension Helm chart to the EKS cluster
const matrixDimensionChart = new k8s.helm.v3.Chart("matrix-dimension-chart", {
    repo: "my-helm-repo", // Replace with the Helm repo URL or name where the chart is located
    chart: "matrix-dimension", // The name of the chart
    version: "1.0.0", // Replace with the desired chart version
    // You can specify the values for the chart like below, or use a config file with `valueYamlFiles`.
    values: {
        // Provide necessary values for the Helm chart here
    },
}, { provider: cluster.provider });

// Export the Helm chart internet-facing endpoint, assuming it creates a LoadBalancer service.
```

A few things to note in the program above:

- Replace `"my-helm-repo"` with the correct Helm repository URL or alias where the `matrix-dimension` chart is hosted.
- The `values` field within the `matrixDimensionChart` declaration should be filled with the configuration values appropriate for `matrix-dimension` Helm chart. You can find these values in the chart's `values.yaml` file or the chart's documentation.
- The `{ provider: cluster.provider }` line ensures that the Helm chart is deployed to the provisioned EKS cluster. The `provider` prop in Pulumi Kubernetes resources allows you to specify which Kubernetes cluster to use.
- The `kubeconfig` and `repositoryUrl` are exported so that you can interact with your EKS cluster and ECR repository outside of Pulumi if needed.
- The final export, which extracts the LoadBalancer service endpoint, would be how you expose services to the public. If the Helm chart creates such a service, you can grab its endpoint from the service spec to make it accessible outside the cluster.

Since Helm charts can be customized, you should check the `matrix-dimension` Helm chart's documentation for any specific configurations required for deployment. Adjust the `values` or provide a YAML configuration file as needed.

Please ensure to replace placeholder strings like `"my-cluster"`, `"my-repo"`, and `"matrix-dimension-chart"` with the actual names you wish to use for your resources. Also, adjust the `desiredCapacity`, `minSize`, and `maxSize` according to your application's requirements.

This program assumes that you have Pulumi and the necessary AWS SDKs installed and configured correctly. Please refer to the [Pulumi AWS EKS documentation](https://www.pulumi.com/docs/reference/pkg/eks/cluster/) for more information on configuring the EKS cluster with Pulumi.
