1. Deploy the elasticsearch-operator helm chart on AWS EKS


    To deploy the elasticsearch-operator helm chart on an AWS Elastic Kubernetes Service (EKS) cluster using Pulumi, you will need to perform the following steps:

    1. Set up an EKS cluster.
    2. Deploy the elasticsearch-operator helm chart to the EKS cluster.

    Here's a detailed explanation and the corresponding Pulumi program written in TypeScript to accomplish this:

    Step 1: Setting Up an EKS Cluster

    First, we need to create an EKS cluster. We will use the eks.Cluster resource from the Pulumi EKS package. This resource will provision an EKS cluster with all the necessary underlying AWS resources such as VPC, subnets, and worker nodes. You can customize the configuration to suit your needs, but for simplicity, we will go with default configurations provided by Pulumi.

    Step 2: Deploying the Elasticsearch Operator Helm Chart

    After setting up the EKS cluster, we will deploy the elasticsearch-operator using the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. A helm chart is a collection of pre-configured Kubernetes resources that can be deployed as a single unit. Pulumi allows you to manage helm charts as resources in your infrastructure code.

    Now, let's write the program:

    import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster with the default configuration const cluster = new eks.Cluster("my-cluster", {}); // Export the cluster's kubeconfig and name export const kubeconfig = cluster.kubeconfig; export const clusterName = cluster.eksCluster.name; // Create a provider for the EKS cluster to be able to deploy resources to it const provider = new k8s.Provider("eks-provider", { kubeconfig: cluster.kubeconfig, }); // Deploy the elasticsearch-operator Helm chart to the EKS cluster const elasticsearchOperatorChart = new k8s.helm.v3.Chart("elasticsearch-operator", { chart: "elasticsearch-operator", // Replace with the appropriate repo URL or name where the chart is hosted repo: "PLACEHOLDER_FOR_HELM_REPO", // Optional: if you have specific version requirements, you can specify a version version: "PLACEHOLDER_FOR_VERSION", }, { provider }); // Export the status of the Helm chart so we can tell when it's finished deploying export const elasticsearchOperatorStatus = elasticsearchOperatorChart.status;

    In this program:

    • We created an instance of an EKS cluster called my-cluster.
    • We exported the cluster's kubeconfig and name as output properties, which you can use to access your cluster with tools like kubectl.
    • We created a K8s provider tied to our new EKS cluster to allow Pulumi to interact with it.
    • We then deployed the elasticsearch-operator helm chart into the EKS cluster using Helm. Note that you need to replace PLACEHOLDER_FOR_HELM_REPO with the actual repository URL where the elasticsearch-operator chart is hosted and PLACEHOLDER_FOR_VERSION with the version number if you have a specific version in mind.
    • Lastly, we exported the status of our helm deployment for visibility.

    This program assumes that you have the necessary AWS credentials configured in your Pulumi environment, as well as Pulumi CLI and required plugins installed. It also assumes that the repository containing the elasticsearch-operator helm chart is known and accessible.

    Remember to replace placeholders with actual values. After you set up the code, run pulumi up to deploy the EKS cluster and the elasticsearch-operator Helm chart.
