How do I deploy the zookeeper-helm-chart on AWS EKS?

To deploy the Zookeeper Helm chart on an AWS EKS cluster using Pulumi, you need to follow these steps:

1. Create an EKS Cluster: This involves setting up the necessary infrastructure on AWS to support Kubernetes.
2. Deploy the Zookeeper Helm Chart: Use the Helm provider to deploy the Zookeeper chart on the EKS cluster.

Below is a detailed explanation and the Pulumi program written in TypeScript to accomplish this.

Explanation

1. EKS Cluster: We use the eks.Cluster resource from the @pulumi/eks package to create an EKS cluster. This abstracts away a lot of the complexity involved in setting up an EKS cluster and provides a high-level interface.
2. IAM Role: An IAM role is created to allow the EKS cluster to manage AWS resources.
3. Helm Chart Deployment: We use the kubernetes.helm.v3.Chart resource from the @pulumi/kubernetes package to deploy the Zookeeper Helm chart. This simplifies the process of deploying Helm charts on Kubernetes.

Pulumi Program

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("zookeeper-cluster", {
    instanceType: "t2.medium",
    desiredCapacity: 2,
    minSize: 1,
    maxSize: 3,
    // Enable the default node group
    skipDefaultNodeGroup: false,
});

// Create an IAM Role for the EKS cluster
const role = new aws.iam.Role("eksRole", {
    assumeRolePolicy: aws.iam.assumeRolePolicyForPrincipal({
        Service: "eks.amazonaws.com",
    }),
});

// Attach the AmazonEKSClusterPolicy to the role
new aws.iam.RolePolicyAttachment("eksRolePolicyAttachment", {
    role: role.name,
    policyArn: "arn:aws:iam::aws:policy/AmazonEKSClusterPolicy",
});

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

// Deploy the Zookeeper Helm Chart
const zookeeperChart = new k8s.helm.v3.Chart("zookeeper", {
    chart: "zookeeper",
    version: "6.2.3",
    fetchOpts: {
        repo: "https://charts.bitnami.com/bitnami",
    },
    values: {
        // Any custom values for the Helm chart
    },
}, { provider: cluster.provider });

// Export the cluster's name
export const clusterName = cluster.eksCluster.name;

Explanation of the Code

1. EKS Cluster: The eks.Cluster resource is used to create an EKS cluster with a specified instance type and node group configuration.
2. IAM Role: An IAM role is created and the AmazonEKSClusterPolicy is attached to it, allowing the EKS cluster to interact with AWS resources.
3. Kubeconfig Export: The kubeconfig for the cluster is exported, allowing you to interact with the cluster using kubectl or other Kubernetes tools.
4. Helm Chart Deployment: The Zookeeper Helm chart is deployed using the kubernetes.helm.v3.Chart resource. The chart is fetched from the Bitnami repository, and any custom values can be specified in the values object.

This Pulumi program will set up an EKS cluster on AWS and deploy the Zookeeper Helm chart on it. You can run this program using the Pulumi CLI to create and manage your cloud resources.
