Deploy the ibm-pem-standard-prod helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy the `ibm-pem-standard-prod` Helm chart on a Rancher-managed Kubernetes cluster, we'll need to follow a series of steps:

1. Configure the Rancher2 Pulumi provider with the information needed to interact with your Rancher server.
2. Import or create a Kubernetes cluster on Rancher if you don't already have one.
3. Create a `CatalogV2` resource that points to the Helm chart repository.
4. Deploy the Helm chart to your chosen cluster using the `AppV2` resource.

Before we start writing the program, make sure you have set up your `rancher2` provider correctly. You'll need credentials that allow you to connect to the Rancher API. This typically includes an API token and the base URL to the Rancher server.

**Installing Helm on Rancher**

First, you'll need to add the Helm chart repository as a catalog within Rancher. This makes the chart available for deployment. Since there's no specific Pulumi resource for `ibm-pem-standard-prod`, we would generally use Rancher to add the IBM chart repository manually or by using the `rancher2.CatalogV2` resource if the Helm repository URL is known.

**Deploying a Helm Chart on Rancher**

Once the chart is in the catalog, you can deploy it using the `rancher2.AppV2` resource, which represents a Helm chart installation in a Rancher context.

Let's write a Pulumi TypeScript program to represent these steps. Please note that this code will not run until the correct Helm chart repository URL for `ibm-pem-standard-prod` is provided.

```typescript
import * as rancher2 from "@pulumi/rancher2";
import * as k8s from "@pulumi/kubernetes";

// Initialize the Pulumi program with the Rancher provider.
const rancherProvider = new rancher2.Provider("rancherProvider", {
    // Set your Rancher API URL here
    apiUrl: "https://your-rancher-api-url",
    // Set your Rancher API Token here
    tokenKey: "Your API Token Here",
});

// Create a new Rancher Cluster or use an existing one.
// Replace the below properties with your cluster's specifics.
const cluster = new rancher2.Cluster("my-cluster", {
    description: "My Rancher managed Kubernetes cluster",
    // ... other necessary cluster configuration ...
}, { provider: rancherProvider });

// Create a Catalog to add the Helm repository.
// Supply the correct Helm chart repository URL here instead of `https://example.com/helm/charts`.
const ibmCatalog = new rancher2.CatalogV2("ibm-catalog", {
    clusterId: cluster.id, // Assuming you're targeting an existing or new cluster managed by Rancher
    url: "https://chart-repo-url-for-ibm-pem-standard-prod",
    gitBranch: "main",
    // ... other necessary catalog configuration ...
}, { provider: rancherProvider });

// Use a Rancher App resource to deploy the Helm chart.
const ibmHelmChart = new k8s.helm.v3.Chart("ibm-pem-standard-prod", {
    chart: "ibm-pem-standard-prod",
    version: "1.0.0", // Replace with the correct chart version
    namespace: "default", // Specify the namespace to deploy the Helm chart to
    // Values for the helm chart should be provided based on the chart's specifications.
    values: {
        // ... specify values to configure `ibm-pem-standard-prod` ...
    },
}, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigRaw }) });

// Export the Kubernetes cluster name and the Helm release status
export const clusterName = cluster.name;
export const ibmHelmChartStatus = ibmHelmChart.status;
```

In this program, we configure the Pulumi Rancher provider with the Rancher API URL and token. Then, we set up a `rancher2.CatalogV2` resource that points to the Helm chart repository for the `ibm-pem-standard-prod` chart (this URL needs to be provided by you; here it's represented with a placeholder). After that, we use the `k8s.helm.v3.Chart` resource to deploy the Helm chart to a namespace in our Kubernetes cluster, sourcing the kubeconfig from the created cluster resource.

This program assumes that you're working with an existing Rancher-managed Kubernetes cluster or creating a new one, and that you've set up your Pulumi program with the necessary credentials. Adjust the code to match the specifics of your Helm chart, Rancher server, and cluster configuration.

Remember that before running this Pulumi program, you must ensure both `@pulumi/rancher2` and `@pulumi/kubernetes` NPM packages are installed. You can install them using npm or yarn:

```bash
npm install @pulumi/rancher2 @pulumi/kubernetes
```

or

```bash
yarn add @pulumi/rancher2 @pulumi/kubernetes
```

Finally, replace the placeholders such as chart repository URL, API URL, token, and other configurations with the actual values for your environment. When you run this program with Pulumi, it will deploy the specified Helm chart to your Rancher-managed Kubernetes cluster.
