1. Deploy the webapp-db-java helm chart on Rancher


    Deploying a Helm chart on Rancher using Pulumi consists of several steps. First, you'll need to have a Kubernetes cluster managed by Rancher, and then you'll use the Rancher 2 Pulumi provider to deploy your Helm chart into that cluster.

    For this example, I will assume you already have a Kubernetes cluster registered with Rancher and that you have set up Pulumi to work with Rancher and Kubernetes. If not, you should:

    1. Create a Kubernetes cluster.
    2. Register the cluster with your Rancher instance.
    3. Install the rancher2 provider using npm install @pulumi/rancher2.
    4. Ensure your Pulumi environment can authenticate to both Rancher and Kubernetes.

    Below is a Pulumi program that demonstrates how to use the rancher2 provider to deploy a Helm chart to a Kubernetes cluster managed by Rancher. We'll use the rancher2.CatalogV2 resource to define a Helm repo, then apply the webapp-db-java chart from this repo using the rancher2.AppV2 resource.

    Make sure you replace the <YOUR_*> placeholders with your specific values:

    • <YOUR_RANCHER_API_URL>: The API URL of your Rancher instance.
    • <YOUR_CLUSTER_ID>: ID of your registered Kubernetes cluster in Rancher.
    • <YOUR_HELM_REPO_URL>: URL of the Helm repository that contains your webapp-db-java chart.
    • <YOUR_CHART_NAME>: The name of your chart in the Helm repository.
    • <YOUR_CHART_VERSION>: The version of the chart you want to deploy.
    • <YOUR_CATALOG_NAME>: A custom name for your catalog resource in Pulumi.
    • <YOUR_NAMESPACE>: Kubernetes namespace to which the chart should be deployed.
    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; // Define the catalog for the Helm chart repository const helmRepo = new rancher2.CatalogV2("webapp-db-java-repo", { url: "<YOUR_HELM_REPO_URL>", clusterId: "<YOUR_CLUSTER_ID>", name: "<YOUR_CATALOG_NAME>", }); // Now deploying the Helm chart to the registered Kubernetes cluster const app = new rancher2.AppV2("webapp-db-java-app", { clusterId: "<YOUR_CLUSTER_ID>", namespace: "<YOUR_NAMESPACE>", repoName: helmRepo.name, chartName: "<YOUR_CHART_NAME>", chartVersion: "<YOUR_CHART_VERSION>", }); // To access the App after it is deployed // Output the App's name, namespace, and repo it was deployed from export const appName = app.name; export const appNamespace = app.namespace; export const appRepoName = app.repoName;

    Let me explain the program:

    1. We import the Pulumi and Rancher2 packages.
    2. We define a Helm repository catalog resource in Rancher using CatalogV2.
    3. We deploy the Helm chart using the AppV2 resource. It references the CatalogV2 using the repo name to deploy the webapp-db-java app.
    4. We export some of the application's details, which provide us with output visible in the Pulumi console after a successful deployment.

    Make sure to replace placeholders with the actual values that apply to your setup. Once you run this Pulumi program, it will communicate with Rancher to deploy your Helm chart to your Kubernetes cluster.
