Deploy the vkpr helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy the vkpr Helm chart on Rancher using Pulumi, you will go through a series of steps that involve creating a Rancher cluster (unless you already have one), installing a catalog that includes vkpr, and then deploying the chart from that catalog.

Before you start, ensure that Pulumi and the Rancher2 Pulumi provider are properly installed and set up. Here are the high-level steps of what we'll be doing:

1. Define the Rancher cluster where the vkpr Helm chart will be deployed. In this case, we will use the `rancher2.Cluster` resource.

2. Add a catalog to your Rancher setup that includes vkpr. Catalogs can be added using the `rancher2.CatalogV2` resource. Catalogs in Rancher allow you to define Helm chart repositories that you can deploy workloads from.

3. Deploy the vkpr Helm chart to your Rancher cluster using the `rancher2.AppV2` resource. This step assumes that you have already set up the catalog containing the vkpr Helm chart.

The following TypeScript Pulumi program provides a high-level template for carrying out these steps. Note that some placeholder values need to be replaced with values specific to your setup, such as the `clusterId`, `catalogUrl`, and `namespace`.

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

// Step 1: Define the Rancher cluster (or use an existing one)
const cluster = new rancher2.Cluster("my-cluster", {
    // Configure your cluster properties here
    // This example includes only the required name field, but a real cluster
    // definition will be more complex and include the specifics for the node pools,
    // networking, cloud provider, Kubernetes version, and more.
    name: "my-cluster"
});

// Step 2: Add a catalog to Rancher with the vkpr Helm chart
const vkprCatalog = new rancher2.CatalogV2("vkpr-catalog", {
    // Replace the URL with the URL for your vkpr Helm chart repository
    url: "https://your-vkpr-helm-chart-repository-url",
    clusterId: cluster.id, // Use the `id` of the cluster where you want to install the catalog
    name: "vkpr",
});

// Step 3: Deploy the vkpr Helm chart using the AppV2 resource
const vkprApp = new rancher2.AppV2("vkpr-app", {
    // Use the cluster ID and namespace where you want to deploy vkpr
    clusterId: cluster.id, // Reference the cluster ID from the cluster resource
    namespace: "default", // Specify the namespace here
    repoName: vkprCatalog.name, // Reference the repo name from the catalog resource
    chartName: "vkpr", // Specify the exact chart name within the vkpr catalog
    // Include additional chart values or configurations here if necessary
});

// Export the URL of the Rancher UI for accessing the deployed application
export const rancherUIUrl = `https://${cluster.id}.your-rancher-instance.com`;
```

Please replace `"https://your-vkpr-helm-chart-repository-url"` with the actual URL of your vkpr Helm chart repository and adjust the cluster properties as needed to match your infrastructure.

This program outlines how you might use Pulumi to deploy a Helm chart to a Rancher cluster. In practice, you would need to adjust the placeholders and omitted details with information specific to your Rancher setup, Helm chart requirements, and cloud environment.
