Deploy the prometheus-operator-csv helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the Prometheus Operator on an AWS EKS cluster using Pulumi and a Helm chart, you would typically follow these general steps:

1. Set up an AWS EKS cluster.
2. Configure your Kubernetes provider to connect to the EKS cluster.
3. Use the Helm chart resource to deploy the Prometheus Operator chart.

In this program, we'll be using the `eks.Cluster` resource from the `eks` package to create an EKS cluster, the `kubernetes.Provider` resource to configure our connection to the EKS cluster, and the `helm.v3.Chart` resource from the `kubernetes` package to deploy the Prometheus Operator Helm chart.

This program in TypeScript assumes that you have Pulumi installed and configured with the necessary AWS credentials. Here is how you would write the code:

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

// Step 1: Create an EKS cluster
const cluster = new eks.Cluster('my-cluster', {
  desiredCapacity: 2,     // Minimum two worker nodes
  minSize: 1,
  maxSize: 3,
  storageClasses: 'gp2',  // General Purpose SSD volume type
  deployDashboard: false,  // Skip deploying the Kubernetes dashboard
});

// Step 2: Configure the Kubernetes provider to connect to the created EKS cluster.
const provider = new k8s.Provider('k8s-provider', {
  kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Step 3: Deploy the Prometheus Operator Helm chart on the EKS cluster.
const prometheusChart = new k8s.helm.v3.Chart('prometheus-operator', {
  chart: 'prometheus-operator',
  version: '9.3.1', // Specify the chart version you want to deploy
  fetchOpts:{
    repo: 'https://prometheus-community.github.io/helm-charts',
  },
}, { provider });

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

```

In the code above:

- We're creating a new EKS cluster using the `eks.Cluster` resource. You can adjust the desired capacity and the size to match your needs.
  
- We configure a new Kubernetes provider that will allow us to interact with the EKS cluster we created. For this, we provide the `kubeconfig` which is output by the EKS cluster.

- Then, using the `k8s.helm.v3.Chart` resource we deploy the Prometheus Operator Helm chart to the cluster. We specify the chart name, the version, and the repository URL.

- Finally, we export the `kubeconfig` so that you can interact with the cluster from your local machine using `kubectl` if needed.

Make sure to replace `'9.3.1'` with the version of the Prometheus Operator you want to install if it's different. You can find the available versions in the Helm repo you're using. In this case, it's from the Prometheus community's Helm chart repository.

You can deploy this Pulumi program by running `pulumi up` from your command line. Make sure your AWS credentials are configured properly and that the Pulumi CLI has been installed and set up to work with your account.
