Deploy the circleci-runner helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the circleci-runner Helm chart on AWS EKS using Pulumi, you will need to follow several steps. The deployment involves:

1. Creating an EKS cluster using the `eks.Cluster` module, which will be our Kubernetes environment.
2. Deploying a Helm chart on this EKS cluster using the `kubernetes.helm.sh/v3.Chart` resource.

First, you'll need to set up an EKS cluster, which is a managed Kubernetes service provided by AWS. The `eks.Cluster` resource in Pulumi creates and manages an EKS cluster for you. It will handle the creation of all necessary AWS resources, including IAM roles and security groups.

After setting up the EKS cluster, you'll use the `kubernetes.helm.sh/v3.Chart` resource from Pulumi's Kubernetes provider to deploy the circleci-runner Helm chart to the cluster. Helm is the package manager for Kubernetes, which allows you to define, install, and upgrade even the most complex Kubernetes applications.

Here's a TypeScript program that will perform these tasks:

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

// Step 1: Create an EKS cluster
const cluster = new eks.Cluster("my-cluster", {
    // You can specify additional options here according to your requirements.
    // For instance: instanceType, desiredCapacity, minSize, maxSize, etc.
});

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

// Step 2: Deploy the circleci-runner Helm chart
const circleciRunnerChart = new k8s.helm.v3.Chart("circleci-runner", {
    chart: "circleci-runner",
    repo: "circleci-runner-repo", // Use the correct Helm repo here
    namespace: "circleci-runner-namespace", // Use the namespace where you want to deploy the runner
    // You can include additional Helm values by specifying the `values` property.
    // For example: values: { key: "value" }
}, { provider: cluster.provider });

// Once your chart is deployed, you can export any of the necessary information, such as service
// endpoints, using pulumi's `export`.
```

This program initializes a new EKS cluster and deploys the circleci-runner Helm chart to it. Ensure you have the correct Helm repository URL to download the chart. You might need to specify additional configuration parameters according to the circleci-runner chart's documentation or your specific requirements.

When you run this program with Pulumi, it will provision the EKS cluster and deploy the specified Helm chart. You can then use the exported kubeconfig to interact with your Kubernetes cluster via `kubectl` or any other Kubernetes management tool.

The `exports` in the program will output the kubeconfig so that you can connect to your EKS cluster after it has been provisioned.

Remember, before you attempt to run this Pulumi program, you need to have Pulumi CLI installed and AWS credentials configured on your machine. You also need to set up and install `kubectl` to interact with the cluster. Moreover, make sure that you have the necessary permissions for creating EKS clusters in your AWS account.
