Deploy the zookeeper-3Nodes helm chart on Kubernetes

To deploy a Helm chart onto a Kubernetes cluster using Pulumi, we can use the Chart resource from the @pulumi/kubernetes package. The Chart resource allows you to deploy a Helm chart from a local directory or a remote chart repository. In this example, we will be deploying the "zookeeper-3Nodes" Helm chart, which is a distributed configuration service for managing a large set of hosts.

Before you begin, ensure that you have Pulumi installed and configured to use with your Kubernetes cluster. You will also need to have kubectl installed and configured to manage your Kubernetes cluster, and Helm installed if you need to customize or fetch Helm charts locally.

Here's the Pulumi TypeScript program that deploys the "zookeeper-3Nodes" Helm chart:

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

const name = "zookeeper-3nodes";
const namespace = "default"; // Choose the namespace where you want to deploy the chart.

// Deploy the zookeeper-3Nodes Helm chart.
const zookeeperChart = new k8s.helm.v3.Chart(name, {
    chart: "zookeeper",
    version: "3Nodes", // Replace with the actual version number of the zookeeper chart that you wish to deploy.
    namespace: namespace,
    repo: "bitnami", // Assuming the chart is in the Bitnami Helm repository; otherwise, specify the correct one.
    values: {
        // Provide custom values for the Helm chart here if necessary.
        // For example (the values need to correspond to the actual Helm chart values):
        // replicaCount: 3,
        // environment: {
        //     ZOOKEEPER_HEAP_SIZE: "2G"
        // },
    },
}, { provider: k8sProvider }); // Ensure you have a K8s provider configured if not using the default context.

// Export the Zookeeper Chart status
export const zookeeperChartStatus = zookeeperChart.status;

This program performs the following steps:

• It imports the @pulumi/kubernetes package to interact with Kubernetes.
• The zookeeperChart constant initializes a new Helm chart using the Chart resource. This is where you provide the Helm chart's name, version, namespace, and any custom values you wish to provision the chart with.
• The export statement allows you to output the status of the deployment, which you can view after the deployment is completed.

If you have a custom set of values you would like to override in the zookeeper chart, you can provide them in the values option of the Chart resource. These values would typically be provided in Helm's values.yaml file when using Helm CLI directly.

Please replace "3Nodes" with the correct version of the zookeeper Helm chart you are trying to deploy. Also, if the chart is not located in the bitnami repository, you will need to change the repo field to point to the correct Chart repository.

Moreover, if you are not using the default kubectl context for connecting to your Kubernetes cluster, you will need to create a Pulumi Kubernetes Provider and pass it to the Chart resource through the provider option.

After writing this code, you can deploy the chart by running pulumi up in your command line. Pulumi CLI will perform the deployment and show you the live status updates of the resources being created. Once the deployment is successful, you can check the exported zookeeperChartStatus to see the status of the deployed Helm chart.
