Deploy the elasticsearch-operator helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the Elasticsearch operator Helm chart on a Kubernetes cluster, you can use the Pulumi kubernetes package, which allows you to manage Kubernetes resources, including deploying Helm charts. The kubernetes.helm.v3.Chart resource will be used in this case because it's designed to deploy Helm charts.

Here's a step-by-step guide followed by a Pulumi program in TypeScript:

Setting Up the Project: Set up a new Pulumi TypeScript project if you haven't already.
Install Required Packages: Make sure you have @pulumi/kubernetes installed in your project using npm or yarn.
Import Dependencies: Import necessary Pulumi and Kubernetes libraries in your Pulumi program.
Instantiate Kubernetes Provider: If your Kubernetes cluster is not the default one configured in your machine or you have specific configuration, create a Kubernetes provider instance, configuring it with the desired context, namespace, or other required properties.
Create Helm Chart Resource: Use the kubernetes.helm.v3.Chart class to create an instance of the Elasticsearch operator Helm chart. You will pass configuration details like the chart name, version, and any custom values you need to override in the Helm chart.
Running the Program: You can deploy your stack with this program using the Pulumi CLI: run pulumi up to execute the deployment.

Here is the Pulumi program that accomplishes this:

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

// Step 1: Set up the Kubernetes provider.
// Note: Assuming your current kubeconfig is set for the correct context,
// otherwise, you can specify the context or other kubeconfig settings.
const provider = new kubernetes.Provider("provider", {});

// Step 2: Deploy the Elasticsearch operator using the Helm chart.
const elasticsearchOperatorChart = new kubernetes.helm.v3.Chart(
  "elasticsearch-operator",
  {
    chart: "elasticsearch-operator",
    version: "<chart version>", // specify the chart version you want to deploy
    fetchOpts:{
      repo: "<helm chart repository url>", // specify the repository URL of the helm chart
    },
    // You may also specify any namespace or values that are required for this chart.
    // For example:
    // namespace: "elasticsearch",
    // values: {},
  },
  { provider: provider }
);

// Step 3: Export any relevant outputs.
export const elasticsearchOperatorChartName = elasticsearchOperatorChart.metadata.name;

Remember to replace <chart version> with the specific version number of the Elasticsearch operator chart you wish to deploy. If you have a specific Helm repository where the chart is located, replace <helm chart repository url> with the actual URL.

Once the program is ready, save it and run pulumi up. This command will prompt you for confirmation before applying the changes to your Kubernetes cluster. After confirming, Pulumi will deploy the Elasticsearch operator Helm chart according to your specifications.
