Deploy the desktop-vnc helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy the `desktop-vnc` Helm chart on a Rancher-managed Kubernetes cluster, you will need to perform the following high-level steps:

1. Set up a Rancher Kubernetes cluster.
2. Install and configure the Rancher provider for Pulumi.
3. Deploy the `desktop-vnc` Helm chart to the Rancher Kubernetes cluster.

For step 1, we will assume that you have already provisioned a Rancher Kubernetes cluster and have access to it.

For step 2, we will set up the Rancher provider for Pulumi. The Rancher provider allows Pulumi to manage resources in a Rancher environment.

For step 3, we will use the `pulumi-kubernetes` package to deploy the `desktop-vnc` Helm chart to your cluster.

Below is a detailed TypeScript program that you can use with Pulumi to deploy the `desktop-vnc` Helm chart on Rancher:

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

// Setup the Rancher provider configurations.
// These are placeholder values and should be replaced with the actual configuration details.
const rancherProvider = new rancher2.Provider("rancher-provider", {
    apiUrl: "https://your-rancher-api-url", // Specify your Rancher API URL
    accessKey: "your-rancher-access-key",    // Replace with your Rancher Access Key
    secretKey: "your-rancher-secret-key",    // Replace with your Rancher Secret Key
});

// Reference to a Rancher2 Kubernetes cluster
// Here you would input the identifier for your Rancher-managed cluster
const cluster = new rancher2.Cluster("cluster", {
    name: "my-cluster-name",
}, { provider: rancherProvider });

// Kubernetes provider based on the above Rancher2 cluster
// This provider is used to deploy resources to the specified cluster
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeConfig,
});

// Deploy the `desktop-vnc` Helm chart to the Rancher Kubernetes cluster.
const desktopVncChart = new k8s.helm.v3.Chart("desktop-vnc", {
    chart: "desktop-vnc",
    // Replace 'chartRepoName' with the name of the Helm chart repository
    // And specify any chart values you want to override under `values`
    fetchOpts: {
        repo: "https://chart-repo-url/", // Put the URL of the Helm chart repository here
    },
    values: {
        // Define any specific configurations you want to apply to the desktop-vnc chart.
        // For example:
        // service: {
        //   type: "NodePort",
        // },
        // This is where you customize the chart deployment to suit your needs.
    },
}, { provider: k8sProvider });

// Export the resources we created, if needed.
export const clusterName = cluster.name;
export const desktopVncChartName = desktopVncChart.metadata.name;
```

In this program, you configure the Rancher provider with access to your Rancher server API and deploy the `desktop-vnc` Helm chart to your Rancher-managed Kubernetes cluster. The `kubeconfig` is pulled directly from the cluster's output, allowing the Kubernetes provider to interact with the cluster.

Make sure you replace placeholder values with actual values from your environment, including the Rancher API URL, cluster name, access key, and secret key. You will also need the URL of the Helm chart repository where the `desktop-vnc` chart is stored.

To use this Pulumi program:

1. Save the code to a file called `index.ts`.
2. Run `pulumi up` to preview and deploy the changes.

Pulumi will show you a preview of the actions to be taken and, upon confirmation, proceed to apply the changes to your Rancher-managed Kubernetes cluster, which will result in deploying the `desktop-vnc` Helm chart.
