Deploy the tsorage helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy a Helm chart on Rancher, you'll need to manage Kubernetes resources through the Rancher2 provider in Pulumi. This involves several steps:

1. Importing the necessary Pulumi Rancher2 package.
2. Setting up a Rancher2 provider to manage resources in your Rancher environment.
3. Deploying the Helm chart using the Rancher2 provider.

We'll use the `rancher2` package to interact with your Rancher instance. The following program will guide you on how to deploy the "tsorage" Helm chart to a Rancher-managed Kubernetes cluster. Ensure that you have the necessary access rights and credentials set up in your Rancher instance to execute these actions.

Here is the TypeScript program that performs the deployment:

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

// Replace these values with the appropriate values for your Rancher setup
const rancherUrl = 'https://your-rancher-instance-url.com';
const tokenKey = 'token-xxxxx:xxxxxxxxxxxxxxxxxxxx';
const clusterId = 'c-xxxxx'; // Cluster ID where the Helm chart will be deployed
const namespaceName = 'default'; // The namespace to which the chart will be deployed
const chartName = 'tsorage'; // Name of the Helm chart
const chartVersion = '1.0.0'; // Specify the chart version you want to deploy

// Instantiate a Rancher2 provider instance with the given credentials
const rancherProvider = new rancher2.Provider("rancher", {
    apiUrl: rancherUrl,
    tokenKey: tokenKey,
});

// Deploy the "tsorage" Helm chart to the specified Rancher cluster and namespace
const tsorageHelmChart = new rancher2.AppV2("tsorage-chart", {
    clusterId: clusterId,
    namespace: namespaceName,
    repoName: "helm-charts", // This should be the name of the repo where your chart is hosted
    chartName: chartName,
    chartVersion: chartVersion,
}, { provider: rancherProvider });

// Export the App name
export const appName = tsorageHelmChart.name;
```

In this Pulumi program:

- We import the `@pulumi/rancher2` package which contains the necessary modules to create Rancher 2 resources.
- We create a new Rancher provider instance that allows us to interact with our Rancher environment.
- We define a new `AppV2` resource which represents the Helm chart that we want to deploy on the Rancher-managed cluster.
- We specify necessary details like `clusterId`, `namespace`, `chartName`, and `chartVersion`. Please ensure that these values are correctly set according to your Helm chart and Rancher environment.
- We also set the `repoName`, which should be the repository where your Helm chart is stored.

Note: Before running this program, you should have configured your Pulumi environment with authorization to manage resources in Rancher. Also, ensure that you have set up rancher2 as a provider; if not, you can learn how to setup and install [Rancher2 provider](https://www.pulumi.com/registry/packages/rancher2/).

To execute this Pulumi program, you will need to save the code in a `index.ts` file, and then run `pulumi up`. This command will compile the TypeScript code to JavaScript, prompt you to review the changes, and then perform the deployment.
