Deploy the ts-server helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the `ts-server` Helm chart on Digital Ocean Kubernetes Service (DOKS), you'll need to create the DOKS cluster first and then deploy the Helm chart to that cluster. I'll walk you through creating a DOKS cluster and deploying a Helm chart to it using Pulumi with TypeScript.

The primary resources we'll use are:

- `digitalocean.KubernetesCluster` to create and manage the DOKS cluster.
- `kubernetes.helm.v3.Chart` from the `@pulumi/kubernetes` package to deploy the Helm chart once the cluster is ready.

Below is the Pulumi program in TypeScript that orchestrates the deployment:

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

// Step 1: Create a Digital Ocean Kubernetes Cluster
const cluster = new digitalocean.KubernetesCluster("ts-server-cluster", {
    region: digitalocean.Regions.NYC1, // Use the appropriate region here
    version: "latest", // Use a specific version or "latest" for the latest stable
    nodePool: {
        name: "default",
        size: digitalocean.DropletSlugs.DropletS2VCPU2GB, // Choose the appropriate droplet size
        nodeCount: 2, // Set the desired number of nodes
    },
});

// Step 2: Use the cluster's kubeconfig to interact with it using Helm
const kubeconfig = cluster.kubeConfigs[0].rawConfig;

const k8sProvider = new kubernetes.Provider("k8s-provider", {
    kubeconfig: kubeconfig,
});

// Step 3: Deploy the ts-server Helm chart
const tsServerChart = new kubernetes.helm.v3.Chart("ts-server-chart", {
    chart: "ts-server", // The Helm chart name
    // You can specify the Helm repository url using 'fetchOpts'
    // fetchOpts: {
    //    repo: "https://helm-repo-url.com/",
    // },
    values: {
        // Configure your Helm chart values here, as key-value pairs
    }
}, { provider: k8sProvider });

// Export the cluster's name and kubeconfig
export const clusterName = cluster.name;
export const kubeconfigOutput = kubeconfig;
```

In this program:
- A Digital Ocean Kubernetes cluster is created with the desired region, version, and node count. 
- A Kubernetes provider is then created using this kubeconfig from the DOKS cluster.
- The `ts-server` Helm chart is deployed to this cluster using the created Kubernetes provider.

You would have to replace `"ts-server"` with the actual chart name, and if the chart is hosted in a specific Helm repository, you would specify that as well using `fetchOpts`. If the Helm chart requires specific configuration values, these can be specified in the `values` object.

Keep in mind that before running this program, you need to have Pulumi installed and configured, as well as being authenticated with Digital Ocean to create resources in your account. The `@pulumi/digitalocean` and `@pulumi/kubernetes` packages should also be installed in your Pulumi project.
