Deploy the zookeeper-exporter helm chart on AWS EKS

To deploy the zookeeper-exporter Helm chart on Amazon EKS (Elastic Kubernetes Service) using Pulumi, we'll go through the steps required to set up the infrastructure.

We'll perform the following steps:

1. Create an EKS cluster using the high-level eks.Cluster component from Pulumi.
2. Deploy the zookeeper-exporter Helm chart to the EKS cluster we created using the kubernetes.helm.v3.Chart resource.

Prerequisites

Ensure you have the following installed:

• Pulumi CLI
• AWS CLI configured with credentials and default region
• kubectl if you want to interact with the cluster directly
• Node.js and npm if they are not already installed

EKS Cluster Creation

First, we need to create an EKS cluster where our Helm chart will be deployed. The eks.Cluster component from Pulumi simplifies this process by abstracting away much of the complexity involved in setting up an EKS cluster.

Helm Chart Deployment

After the cluster is available, we can deploy the zookeeper-exporter Helm chart using the Pulumi Kubernetes provider. We will interact with the Helm package manager through the kubernetes.helm.v3.Chart resource, which allows us to deploy charts into our cluster.

Here's a Pulumi TypeScript program that accomplishes the deployment of the zookeeper-exporter Helm chart on AWS EKS:

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

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

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

// Create a k8s provider using the kubeconfig from the EKS cluster created above.
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig,
});

// Deploy zookeeper-exporter helm chart to the EKS cluster.
const zookeeperExporterChart = new k8s.helm.v3.Chart("zookeeper-exporter", {
    chart: "zookeeper-exporter",
    version: "0.1.0", // Specify the chart version you want to deploy
    fetchOpts: {
        repo: "https://helm-repo-url/", // Replace with the Helm repository URL
    },
}, { provider: k8sProvider });

// Export the Helm chart's status.
export const helmChartStatus = zookeeperExporterChart.status;

This Pulumi program executes the following:

• It defines an EKS cluster with the specified number of nodes and instance type.
• Once the cluster is up, it exports the kubeconfig which you can use to interact with your cluster via kubectl.
• It creates a Kubernetes provider that is configured to talk to the newly created EKS cluster.
• It uses the Kubernetes provider to deploy the zookeeper-exporter Helm chart. You will need to replace the version and repo with the actual version you want and the Helm chart repository URL containing the zookeeper-exporter chart.

Running the Program

1. Save the code to a file with a .ts extension, for example, deploy-zookeeper.ts.
2. Run pulumi up to preview and deploy the changes.
3. Approve the preview to start the deployment.

Once the deployment succeeds, you can use the exported kubeconfig to configure kubectl and interact with your EKS cluster. You can also check the status of deployment of the Helm chart with the exported helmChartStatus.

Remember to replace "https://helm-repo-url/" with the actual repository URL that hosts the zookeeper-exporter Helm chart. Also, specify the correct chart version as per the Helm repository details.

Refer to the Pulumi EKS Cluster and Kubernetes Helm Chart component documentation for more details on configuration and usage.
