1. Deploy the lodestar-validator helm chart on Rancher


    To deploy the lodestar-validator Helm chart on Rancher using Pulumi, we'll approach this task in several steps:

    1. Set up Rancher: Ensure Rancher is running and accessible.
    2. Add a Catalog: To manage Helm chart repositories in Rancher.
    3. Deploy the Helm Chart: As a workload in the Rancher-managed Kubernetes cluster.

    Pulumi allows us to define and manage cloud resources using code in several programming languages, including TypeScript. Let's use Pulumi's TypeScript SDK to accomplish our task.

    For this task, we'll use the rancher2 provider to interact with the Rancher API and manage resources. We will programmatically:

    • Define a Catalog (CatalogV2) resource, pointing to the Helm repository that contains the lodestar-validator chart.
    • Create a Helm chart (HelmChart) resource that refers to the lodestar-validator chart in the newly defined catalog.

    Here's how to do it in TypeScript:

    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; // Configuration variables for the Helm chart and Rancher settings const catalogName = 'lodestar-catalog'; const apiUrl = 'http://rancher.my.org/v3'; // Replace with your Rancher API URL const helmChartName = 'lodestar-validator'; const helmChartRepo = 'https://lodestar-validator-helm-repo.com'; // Replace with the correct Helm repo URL const targetNamespace = 'lodestar-namespace'; // Namespace where your Helm chart will be deployed // Create a Rancher2 Catalog resource const catalog = new rancher2.CatalogV2(catalogName, { clusterId: "<your-cluster-id>", // Replace with your Cluster ID from Rancher // You might need to provide auth credentials or a secret name if your repo is private url: helmChartRepo, // URL of the Helm repo for the lodestar-validator chart gitBranch: "<default-branch>", // Replace with the main branch if the catalog uses a git repository }); // Deploy the `lodestar-validator` Helm Chart from the catalog const lodestarHelmChart = new rancher2.HelmChart("lodestar-validator-helm-chart", { clusterId: "<your-cluster-id>", // The same cluster ID used in the catalog resource namespaceId: targetNamespace, repoName: catalogName, // Reference to the catalog we created earlier chartName: helmChartName, kubernetesVersion: "<kubernetes-version>", // Replace with the version of Kubernetes running on your cluster version: "<chart-version>", // Replace with the specific version of the lodestar-validator chart // Values in 'set' will depend on the particular configuration you need for lodestar-validator set: { name: "<configuration-key>", // Replace with the actual key of a configuration you want to override value: "<configuration-value>", // Replace with the actual value of the configuration you want to set }, // any other necessary chart values }); // Export the name and status URL of the deployed helm chart export const helmChartNameFqn = lodestarHelmChart.metadata.apply(m => `${targetNamespace}/${m.name}`); export const helmChartStatusUrl = pulumi.interpolate`${apiUrl}/projects/${targetNamespace}:projectid/apps/${helmChartNameFqn}`;

    Before you run this Pulumi program, you should replace placeholder strings like <your-cluster-id>, <default-branch>, <kubernetes-version>, and <chart-version> with actual values relevant to your Rancher setup and the lodestar-validator Helm chart.

    The CatalogV2 resource represents a Helm chart repository in Rancher, with fields for the repository's url and gitBranch. If your Helm repository requires authentication, you will need to include the necessary credentials or reference a Secret in Rancher that contains them.

    The HelmChart resource is where we specify the actual chart we wish to install. We set the repoName to the name given to our CatalogV2 resource, identifying where Rancher will locate the chart. The chartName is the name of the Helm chart in the repository. The set properties are key-value pairs that override default values in the Helm chart.

    Run the Pulumi program using the CLI by navigating to the directory containing the Pulumi program file and executing pulumi up, which will preview and apply the changes.

    Remember that you must have Pulumi installed and configured with the required cloud provider credentials. Ensure that your Rancher instance is accessible from where you run the Pulumi CLI, and you have administrative access to create catalogs and deploy Helm charts.
