Deploy the zookeeper-exporter helm chart on Rancher

To deploy the zookeeper-exporter Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you'll need to perform the following general steps:

1. Set up a new Pulumi project for your infrastructure code if you haven't already.
2. Ensure that your local environment is configured with access to the Rancher server.
3. Install the necessary Pulumi provider for Rancher.
4. Use Pulumi's Rancher2 provider to interact with your Rancher setup.
5. Deploy the Helm chart using the rancher2.CatalogV2 which can be used to add Helm repository and rancher2.AppV2 to deploy applications from the catalog.

First, make sure you have Pulumi and Rancher installed and configured on your local machine. For Rancher, you may need an API token to interact with the Rancher API. Ensure that the access token is properly configured in your environment or Pulumi program where it can be used for authentication.

Below you'll find a Pulumi TypeScript program that adds a Helm chart repository to Rancher and then deploys a Helm chart from that repository. Keep in mind that you will need to have the relevant permissions and access to a Rancher Kubernetes cluster for this to work.

import * as rancher2 from "@pulumi/rancher2";

// Replace the following variables with your respective Rancher cluster details and Helm repo information
const clusterId = "your-cluster-id"; // The ID of your Rancher-managed Kubernetes cluster
const helmRepoUrl = "https://your-helm-chart-repository/"; // URL to your Helm chart repository
const helmChartName = "zookeeper-exporter"; // Name of the Helm chart you want to deploy
const helmChartVersion = "zookeeper-exporter-version"; // Version of the Helm chart to deploy

// Create a new catalog in Rancher that points to a Helm chart repository
const catalog = new rancher2.CatalogV2("zookeeper-exporter-catalog", {
    clusterId: clusterId,
    url: helmRepoUrl,
    // Other optional properties like `gitBranch`, `type`, `caBundle`, etc.
});

// Deploy the zookeeper-exporter Helm chart using the catalog
const zookeeperExporter = new rancher2.AppV2("zookeeper-exporter-app", {
    clusterId: clusterId,
    chartName: helmChartName,
    releaseName: "zookeeper-exporter-release",
    repositoryName: catalog.name, // Reference to the catalog we just created
    version: helmChartVersion,
    // Include any values you want to override the default Helm chart values
    values: `key1: value1\nkey2: value2`,
    // Other optional properties like namespace, project ID, etc.
});

// Export the App ID and Chart Version after deployment
export const zookeeperExporterAppId = zookeeperExporter.id;
export const zookeeperExporterChartVersion = zookeeperExporter.version;

In this program, we've defined a CatalogV2 resource to add the Helm chart repository to Rancher. After that, we created an AppV2 resource to deploy a Helm chart from the previously added catalog. We've specified the cluster ID of the target Kubernetes cluster managed by Rancher, the name of the Helm chart we want to deploy (zookeeper-exporter), and the chart version.

If you need to override default values in the Helm chart, you can supply a multi-line string to the values property of AppV2.

This script assumes that you have already configured the necessary prerequisites, such as Pulumi with necessary credentials and Rancher with a running cluster. After the deployment, we export the application ID and chart version, which can be useful for querying or making further updates through Pulumi.

To run this Pulumi program, save the code to a index.ts file in a new Pulumi project directory. From your command line, navigate to the directory and run pulumi up, which will execute the deployment.
