Deploy the vehicle-dashboard helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy a Helm chart on Rancher using Pulumi, you will need to interact with Rancher's Kubernetes management capabilities. The code below will guide you through setting up a Rancher 2 Kubernetes cluster and deploying a Helm chart to it.

First, ensure you have installed the Pulumi CLI and have authenticated with your Rancher installation. You will also need to ensure that you have the Rancher 2 provider configured within your Pulumi program.

Here is a step-by-step breakdown of what the Pulumi program will do:
1. Set up a new Rancher 2 Kubernetes cluster or reference an existing one.
2. Deploy the `vehicle-dashboard` Helm chart to the specified cluster.

Before you run the Pulumi program, you must have the `vehicle-dashboard` chart available in a repository that the Rancher cluster can access.

The following TypeScript program accomplishes this:

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

// Create a new Rancher 2 cluster or use an existing one.
const cluster = new rancher2.Cluster("vehicle-dashboard-cluster", {
    // Provide the necessary properties for your cluster here
    // e.g., rancher2KubernetesEngineConfig, name, description, etc.
});

// Once your cluster is set up, configure Pulumi to use the cluster's kubeconfig.
const kubeconfig = cluster.kubeconfig.apply(JSON.stringify);
const provider = new kubernetes.Provider("vehicle-dashboard-provider", {
    kubeconfig: kubeconfig,
});

// Deploy the 'vehicle-dashboard' Helm chart to the cluster.
const vehicleDashboardChart = new kubernetes.helm.v3.Chart("vehicle-dashboard", {
    chart: "vehicle-dashboard",
    // Assuming the Helm chart is hosted in a repository, provide repository URL
    // You would also specify the namespace and possibly other options as appropriate.
    fetchOpts: {
        repo: "http://charts.example.com/",
    },
}, { provider: provider });

// Export the base URL of the 'vehicle-dashboard' service.
export const vehicleDashboardUrl = vehicleDashboardChart.getResourceProperty(
    "v1/Service", "vehicle-dashboard", "status"
).apply(status => status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname);
```

In the above program:
- Replace the placeholders in the `Cluster` object with the actual configuration that matches your Rancher setup.
- The kubeconfig of the cluster is used to create a Kubernetes provider. The Rancher 2 cluster must be completely ready and kubeconfig should be accessible.
- The `Chart` resource from the `@pulumi/kubernetes` package is used to deploy the 'vehicle-dashboard' Helm chart, specifying the chart name and repository URL.
- After creating the service for the vehicle-dashboard, we're exporting a publicly accessible URL.

Please modify the chart properties and cluster configuration according to your 'vehicle-dashboard' Helm chart specifications and your Rancher cluster details. Make sure to use the correct repository where your 'vehicle-dashboard' Helm chart is stored.

After writing the above program, save it to a file, say `index.ts`. To deploy this program:

1. Navigate to the directory containing your `index.ts` file in the terminal.
2. Run `pulumi up` and Pulumi will execute the code to set up your Rancher cluster and deploy the 'vehicle-dashboard' Helm chart to it.

Please replace placeholders and provide actual values that match your configuration before running the program.
