Deploy the harbor-operator helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the harbor-operator Helm chart on the Digital Ocean Kubernetes Service using Pulumi, you will perform the following steps:

1. Create a Kubernetes cluster on Digital Ocean.
2. Install the harbor-operator Helm chart onto the cluster.

Below you'll find a TypeScript program that defines a DigitalOcean Kubernetes cluster and then uses the Pulumi Kubernetes provider to deploy the harbor-operator Helm chart on that cluster.

First, you'll need to import the necessary Pulumi packages:

- `@pulumi/digitalocean` is used to create a DigitalOcean Kubernetes cluster.
- `@pulumi/kubernetes` is used to work with Kubernetes resources, such as deploying a Helm chart.

Ensure you have these packages installed in your Pulumi project.

Here's the Pulumi program:

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

// Create a new DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("do-k8s-cluster", {
    region: "nyc3",        // Deploy in the New York 3 region, you can change this to what you prefer
    version: "latest",     // Use the latest version of Kubernetes
    nodePool: {            // Define the node pool configuration
        name: "default",
        size: "s-2vcpu-2gb", // Choose a Droplet size based on your workload
        nodeCount: 2,        // Starts with 2 Droplets (You can adjust the size later)
    },
});

// Use the cluster's kubeconfig to interact with the cluster
const provider = new k8s.Provider("do-k8s-provider", {
    kubeconfig: cluster.kubeConfigs[0].rawConfig,
});

// Deploy the harbor-operator Helm chart
const harborOperatorChart = new k8s.helm.v3.Chart("harbor-operator", {
    chart: "harbor-operator",
    version: "1.0.0",              // Specify the version of the Helm chart
    fetchOpts: {
        repo: "https://helm.goharbor.io", // Add the repository where the harbor-operator chart is located
    },
}, { provider: provider });

// Export the kubeconfig to access your cluster
export const kubeConfig = cluster.kubeConfigs[0].rawConfig;

// Export the Kubernetes cluster name
export const clusterName = cluster.name;
```

This program performs the following actions:

1. It defines a new DigitalOcean Kubernetes cluster named `do-k8s-cluster` with a specified Droplet size and region. You can adjust the region, version (if you want a specific Kubernetes version), Droplet size, and the number of nodes according to your needs.
2. It creates a Pulumi Kubernetes provider to interact with the cluster, utilizing the kubeconfig obtained from the newly created DigitalOcean Kubernetes cluster.
3. It then uses the Pulumi Kubernetes provider to deploy the `harbor-operator` Helm chart. You should replace `1.0.0` with the specific chart version you want to deploy, and ensure that the repo URL points to the correct Helm repository for harbor-operator.
4. Finally, it exports the kubeconfig, allowing you to interact with your cluster using tools like `kubectl`, and it also exports the name of the Kubernetes cluster.

To run this Pulumi program:

1. Save the code in a file named `index.ts`.
2. Run `pulumi up` to preview and deploy the changes. Pulumi will show you what actions will be taken and ask for your confirmation before proceeding with the deployment.

Keep in mind that you will need an account with DigitalOcean and the necessary Pulumi setup to communicate with your DigitalOcean account. Ensure that you've installed the Pulumi CLI and logged in to your account before running the program.
