1. Deploy the zimagi-lib helm chart on Rancher

    TypeScript

    To deploy the zimagi-lib Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you would typically use Pulumi's Kubernetes provider to deploy Helm charts. However, since we need to work within the context of a Rancher-managed cluster, we will use the rancher2 Pulumi provider.

    The rancher2 Pulumi provider allows us to interact with Rancher resources such as Clusters, Catalogs (for Helm repository configuration), and Apps (to deploy Helm charts). Below is a program that accomplishes deploying a Helm chart to a Rancher cluster:

    Firstly, you need to have access to a Rancher-managed Kubernetes cluster and have configured the rancher2 Pulumi provider with the appropriate credentials.

    In the program below, we will:

    1. Add a CatalogV2 resource which refers to the Helm repository containing the zimagi-lib chart.
    2. Deploy the Helm chart using the AppV2 resource, referencing the catalog and specifying the necessary deployment parameters.

    Let's go through the steps in TypeScript:

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

// First, we establish a new catalog referencing the repository that holds the zimagi-lib chart.
// The name should be unique within your Rancher setup.
const catalog = new rancher2.CatalogV2("zimagi-catalog", {
    // Replace 'YOUR_CLUSTER_ID' with the actual cluster ID within your Rancher setup.
    clusterId: "YOUR_CLUSTER_ID",
    // The URL of the Helm chart repository containing the zimagi-lib chart.
    url: "URL_OF_HELM_CHART_REPOSITORY_FOR_ZIMAGI-LIB",
    // Specify the branch of the Helm repository if it's not the default branch.
    gitBranch: "main",
});

// Next, we deploy the zimagi-lib chart using the AppV2 resource.
const app = new rancher2.AppV2("zimagi-lib-app", {
    // Use the same cluster ID as used for the CatalogV2 resource.
    clusterId: "YOUR_CLUSTER_ID",
    // Specify the name of the namespace you want to deploy your app into.
    namespace: "default",
    // The name of the catalog that you've previously set up.
    repoName: catalog.name,
    // The name of the chart you want to deploy.
    chartName: "zimagi-lib",
    // Specify the version of the Helm chart to deploy.
    chartVersion: "VERSION_OF_ZIMAGI-LIB_CHART",
    // Values to pass to the Helm chart, if needed.
    values: {
        // Replace these with actual values required by the zimagi-lib Helm chart.
        key1: "value1",
        key2: "value2",
    },
});

// Use rancher2.AppV2 to deploy zimagi-lib helm chart.
// The Pulumi program below assumes that you have already set up your Pulumi stack with the
// correct configuration to access your Rancher instance, including any necessary credentials.

// Important: This code will not work 'out of the box' and requires customization
// to insert appropriate values where indicated.

// Export the name of the app which can be useful for querying the Rancher API or UI.
export const appName = app.name;

    Before running this Pulumi program, you must replace YOUR_CLUSTER_ID, URL_OF_HELM_CHART_REPOSITORY_FOR_ZIMAGI-LIB, VERSION_OF_ZIMAGI-LIB_CHART, and any Helm chart values (key1, key2, etc.) with the actual values specific to your setup. You can find the cluster ID from your Rancher UI or API, and you should consult the zimagi-lib chart's documentation for the available chart values.

    Once you run this program with Pulumi, it will communicate with your Rancher installation to add the specified catalog and deploy an instance of the zimagi-lib Helm chart into the designated namespace of your Kubernetes cluster managed by Rancher.
