Deploy the cloudwatch-exporter helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the CloudWatch Exporter Helm chart on AWS EKS using Pulumi, we will perform the following steps:

1. **Create an EKS Cluster**: This is a managed Kubernetes service that automatically handles certain aspects of a Kubernetes cluster.
2. **Install CloudWatch Exporter Chart**: We'll use the Kubernetes package to deploy the CloudWatch Exporter Helm Chart on the EKS cluster.

To start, make sure you have [Pulumi](https://www.pulumi.com/docs/get-started/install/) and [AWS CLI](https://aws.amazon.com/cli/) installed and configured.

Now, let's go through the complete Pulumi program step-by-step.

First, we define the EKS cluster:

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

// Create an EKS cluster with the default configuration.
const cluster = new eks.Cluster("my-cluster");

// Export the cluster's kubeconfig and name to be used by kubectl and the Helm chart.
export const kubeconfig = cluster.kubeconfig;
export const clusterName = cluster.eksCluster.name;
```

The above code creates an EKS cluster with some sensible defaults.

Next, we deploy the CloudWatch Exporter Helm chart to the cluster we just created. Pulumi's Kubernetes provider can deploy Helm charts directly:

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

// Create a Kubernetes provider instance that uses our EKS cluster from the step above.
const provider = new k8s.Provider("provider", { kubeconfig: cluster.kubeconfig });

// Deploy the CloudWatch Exporter Helm chart.
const cloudwatchExporterChart = new k8s.helm.v3.Chart("cloudwatch-exporter", {
    chart: "cloudwatch-exporter",
    version: "CHART_VERSION", // Specify the chart version you want to deploy
    fetchOpts: { repo: "https://prometheus-community.github.io/helm-charts" },
}, { provider: provider });

```

Replace `CHART_VERSION` with the specific version of the CloudWatch Exporter Helm chart you want to deploy. You can find chart versions on the Helm chart repository of the application.

The `k8s.Provider` object tells the Helm chart to deploy onto our EKS cluster.

With this Pulumi program, you can deploy the CloudWatch Exporter Helm Chart to an AWS EKS cluster. It's worth noticing that this is a simplified overview of the deployment process, and in a production scenario, you'd need to consider additional aspects such as cluster security, IAM roles, VPC configuration, and the specific configuration of the CloudWatch Exporter Helm chart.

Before running this code with `pulumi up`, ensure you have the Pulumi CLI installed, and you are logged into the Pulumi service or have selected a local backend for state storage. Also, ensure you have your AWS credentials configured either through the AWS CLI or by setting the appropriate environment variables (`AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, and optionally `AWS_SESSION_TOKEN`).
