1. Deploy the myhelmapp helm chart on Rancher


    If you want to deploy a Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you would need to use the Pulumi Rancher2 provider. This provider allows you to interact with Rancher2 resources within your Pulumi program. To deploy a Helm chart, you'd typically use resources like rancher2.CatalogV2 to define a Helm chart repository, and rancher2.AppV2 to deploy the Helm chart from the catalog.

    Below is a Pulumi TypeScript program that demonstrates how to deploy a Helm chart called myhelmapp on Rancher. I'll guide you through it step-by-step.

    First, ensure that you've set up your Pulumi environment with the necessary credentials to interact with your Rancher instance and that you have installed the @pulumi/rancher2 package:

    npm install @pulumi/rancher2

    Here's a step-by-step guide and the TypeScript program for deploying a Helm chart on Rancher:

    1. Define the Helm Chart Repository: Create a new rancher2.CatalogV2 instance to add the repository that contains your Helm chart.
    2. Deploy the Helm Chart: Create a new rancher2.AppV2 instance that references the Helm chart from the added repository.
    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; // Define the Helm chart repository by creating a catalog const catalog = new rancher2.CatalogV2("my-catalog", { // The Helm chart repository URL url: "https://your-helm-chart-repo.com", // The Rancher cluster ID where you want to deploy the chart clusterId: "your-cluster-id", }); // Deploy the Helm chart using the AppV2 resource const app = new rancher2.AppV2("my-helm-app", { // The name of your Helm chart as listed in the repository chartName: "myhelmapp", // The version of the Helm chart you want to deploy chartVersion: "1.0.0", // The namespace where you want to deploy the Helm chart namespace: "default", // Reference the Helm chart repository's name from above repoName: catalog.name, // The Rancher cluster ID where you want to deploy the chart clusterId: "your-cluster-id", // Specify values to customize the Helm chart deployment, use key-value pair values: { key: "value", // Replace with actual value keys for the Helm chart }, }); // Export the App ID export const appId = app.id;

    Make sure to replace "https://your-helm-chart-repo.com" with the actual URL of your Helm chart repository. Also, use the appropriate Rancher clusterId and set any values that your Helm chart requires in the values object.

    After initializing your Pulumi program with pulumi new, you can run it using the following commands:

    pulumi up # This command creates or updates resources

    The pulumi up command will prompt you to confirm the deployment after showing you the plan of what resources will be created or updated. Once you confirm, Pulumi will communicate with your Rancher instance to deploy the specified Helm chart.

    The program concludes by exporting the ID of the deployed Helm chart as appId, which you can use to reference the application in additional Pulumi scripts or for outputting information about the deployment.

    Remember to use meaningful values for chartVersion, namespace, clusterId, and any other values required by the Helm chart to customize the deployment. These will vary based on your specific Helm chart and Rancher setup.
