1. Deploy the xkops helm chart on Rancher

    TypeScript

    To deploy a helm chart on Rancher using Pulumi, you first need to ensure that Rancher is up and running and that you have access to it. In this example, we'll use the rancher2 Pulumi provider, which allows us to interact with Rancher 2.x.

    Here's what we'll do step-by-step:

    1. Create a new namespace in Rancher where the helm chart will be deployed.
    2. Add a catalog to Rancher that contains the helm chart 'xkops'.
    3. Deploy the 'xkops' helm chart to the created namespace.

    Before we begin, you'll need to have Pulumi installed and configured with the appropriate credentials to interact with your Rancher instance. Also, ensure that the rancher2 plugin is installed in your Pulumi environment.

    Below is a Pulumi program written in TypeScript that demonstrates how to carry out the above steps:

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

// Define the Rancher cluster and namespace where the helm chart will be deployed.
const clusterId = "<RANCHER_CLUSTER_ID>"; // Replace with your cluster ID
const xkopsNamespace = new rancher2.Namespace("xkops-namespace", {
    clusterId: clusterId,
    name: "xkops",
    description: "Namespace for the xkops helm chart",
});

// Create a new Catalog containing the helm chart. This assumes 'xkops' is in a helm repository.
const xkopsCatalog = new rancher2.CatalogV2("xkops-catalog", {
    clusterId: clusterId,
    name: "xkops",
    url: "https://<HELM_CHART_REPOSITORY_URL>", // Replace with the actual helm chart repository URL
    gitRepo: "", // Use this if the chart is in a git repository
    branch: "",  // Required if gitRepo is used
    // ...
    // You can specify additional settings like authentication details if the repository is private
});

// Deploy the xkops helm chart from the catalog.
// Note: If this chart requires values, you can define them as a dictionary in `valuesYaml`.
const xkopsHelmChart = new rancher2.AppV2("xkops-helm", {
    clusterId: clusterId,
    namespace: xkopsNamespace.id,
    catalogName: xkopsCatalog.id,
    chartName: "xkops",
    // Replace this value with the specific version you want to install, or remove to install the latest
    chartVersion: "1.0.0", 
    // Example for passing values to the helm chart. Adjust according to your chart's required values:
    // valuesYaml: `key1: value1\nkey2: value2\n...`
});

// Export the name of the namespace and the installed helm chart
export const namespaceName = xkopsNamespace.metadata.apply(meta => meta.name);
export const helmChartName = xkopsHelmChart.metadata.apply(meta => meta.name);

    In this program:

    • We first declare the cluster ID where the helm chart will be deployed. This ID should be obtained from your Rancher interface.
    • We then create a namespace xkops-namespace to logically separate our deployment from other deployments in the cluster.
    • A catalog xkops-catalog is created to add the helm repository that contains the 'xkops' chart. If the chart is stored in a git repository or other source, you would set the gitRepo and associated properties.
    • Finally, we create an instance of the AppV2 resource to deploy the helm chart in the defined namespace using the catalog that was created.

    Replace the placeholders <RANCHER_CLUSTER_ID> and <HELM_CHART_REPOSITORY_URL> with your actual Rancher cluster ID and helm chart's repository URL respectively. Additionally, specify the chartVersion and adjust valuesYaml to include any custom values your helm chart requires.

    After setting up your Pulumi program, run the following commands to deploy the helm chart:

    pulumi stack init xkops-deployment
pulumi up

    After you've reviewed the proposed changes, select 'yes' to proceed with the deployment. The helm chart will be deployed to your Rancher cluster, and you'll see output with the namespace and helm chart's name.
