Deploy the smartctl-exporter helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the `smartctl-exporter` Helm chart on AWS EKS using Pulumi, you'll need to complete a few steps:

1. Create an EKS cluster.
2. Deploy the Helm chart onto the cluster.

Below is a detailed Pulumi program written in TypeScript that accomplishes these steps. The program uses the `@pulumi/eks` package to create an EKS cluster and the `@pulumi/kubernetes` package to deploy the `smartctl-exporter` Helm chart.

First, we will set up the EKS cluster. We define the EKS cluster using the `eks.Cluster` class. This class abstracts away the details of setting up an EKS cluster and configures it with sensible defaults.

Next, we will use the `kubernetes.helm.v3.Chart` resource to deploy the `smartctl-exporter` Helm chart. This resource is part of Pulumi's Kubernetes provider and allows us to deploy Helm charts in a declarative way.

Here's the complete Pulumi program to accomplish the deployment:

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

// Create an EKS cluster.
const cluster = new eks.Cluster("my-cluster", {
    desiredCapacity: 2,
    minSize: 1,
    maxSize: 3,
    instanceType: "t2.medium",
});

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

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

// Deploy the smartctl-exporter helm chart using the Helm Chart resource.
const smartctlExporterChart = new k8s.helm.v3.Chart("smartctl-exporter", {
    chart: "smartctl-exporter",
    version: "1.0.0", // Replace with the actual chart version you want to deploy.
    fetchOpts: {
        repo: "https://your-helm-chart-repository.com/", // Replace with the actual Helm chart repository URL.
    },
}, { provider });

// Export the Helm chart deployment status
export const helmDeploymentStatus = smartctlExporterChart.status;
```

This program creates an EKS cluster, exports the kubeconfig necessary to interact with the cluster, then deploys the `smartctl-exporter` Helm chart. Remember to replace `"1.0.0"` and `"https://your-helm-chart-repository.com/"` with the actual version and repository URL of your Helm chart.

To run this program, you should save it in a file with a `.ts` extension, ensure you have Pulumi installed and configured, and then run it using the Pulumi CLI:

```bash
pulumi up
```

This command initializes the Pulumi program, prompts for any required input, and then performs the deployment. The `pulumi up` command provides a preview of the changes and asks for confirmation before making any changes to your cloud resources. After confirmation, it will apply the changes to deploy the EKS cluster and the `smartctl-exporter` Helm chart.

Remember to check the Pulumi documentation for the [eks.Cluster](https://www.pulumi.com/registry/packages/eks/api-docs/cluster/) and [kubernetes.helm.v3.Chart](https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm.sh/v3/chart/) to fully understand the available options and tune your deployment according to your needs.

Exported values such as `kubeconfig` and `helmDeploymentStatus` can be used to interact with the cluster and check the deployment status from the Pulumi stack outputs.
