1. Deploy the open-pub helm chart on Rancher


    Deploying a Helm chart on a Rancher-managed Kubernetes cluster involves a few steps. Rancher is an open-source multi-cluster management platform that simplifies the deployment and management of Kubernetes clusters. Helm is a package manager for Kubernetes, which allows you to define, install, and upgrade complex Kubernetes applications.

    Here's a breakdown of the main steps we'll take:

    1. We'll start by setting up the Rancher 2 provider in Pulumi, which lets us interact with a Rancher installation programmatically.
    2. We'll ensure we have a Kubernetes cluster managed by Rancher. For simplicity, I will assume that one is already available, and we will use its clusterId.
    3. We'll install a Helm chart using Rancher. We will use the CatalogV2 resource to add a new catalog, which will let us pull in Helm charts.

    The below TypeScript Pulumi program demonstrates how to deploy an open-pub Helm chart to a Rancher-managed Kubernetes cluster:

    import * as rancher2 from "@pulumi/rancher2"; // Replace this with your cluster ID const clusterId = "<YOUR_CLUSTER_ID>"; // Create a new catalog using the CatalogV2 resource const catalog = new rancher2.CatalogV2("open-pub-catalog", { clusterId: clusterId, url: "https://charts.example.com/", // Replace with the URL to the catalog/repository containing 'open-pub' gitBranch: "main", // If the catalog is private, you may also provide `secretName` and `secretNamespace` where credentials are stored }); // Deploy the open-pub helm chart using the AppV2 resource from the rancher2 provider const openPubApp = new rancher2.AppV2("open-pub", { clusterId: clusterId, namespace: "default", // Replace with the namespace where you want to deploy the chart repoName: catalog.metadata.name, chartName: "open-pub", // Assuming that this is the chart name in the Helm repository // Specify the chart version or leave it empty to pull the latest values: ` replicaCount: 2 service: type: ClusterIP `, // Replace with the actual values required for 'open-pub' }); // Export any resource identifiers you may need to access post-deployment export const openPubAppName = openPubApp.metadata.name;

    This program assumes you have a Helm chart repository that contains the open-pub chart and that you've replaced the URL and other placeholders with appropriate values for your specific scenario.

    The CatalogV2 resource adds a new catalog entry within your Rancher 2 environment, which allows you to then use charts from that repository. The AppV2 resource is used to manage the deployment of the Helm chart within the chosen Rancher-managed Kubernetes cluster and namespace.

    In the values field of the AppV2 resource, we input configuration parameters in the form of a YAML string. These parameters depend on the Helm chart itself and should be crafted to suit the particular needs of the open-pub chart you mentioned.

    Please ensure you have the Rancher 2 provider set up within your Pulumi environment and access to a Rancher-managed cluster.

    For documentation on the resources used here, you can visit:

    • rancher2.CatalogV2
    • rancher2.AppV2 (The actual resource name might differ, such as HelmChart or App, depending on the Pulumi Rancher 2 provider's version and the Rancher version itself. Check the official Pulumi Rancher 2 provider documentation for more details.)

    Remember to replace placeholder values with your specific information, such as the cluster ID, the namespace (if not the default), and the URL pointing to your Helm chart repository. The values YAML should also be configured based on the Helm chart's requirements.
