Deploy the standalone-authorizer helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the standalone-authorizer helm chart on Digital Ocean Kubernetes Service (DOKS) using Pulumi, we will perform the following steps:

1. Create a new Kubernetes cluster in DigitalOcean using the `digitalocean.KubernetesCluster` resource.
2. Deploy the helm chart onto the cluster using the `kubernetes.helm.sh/v3.Chart` resource.

Before diving into the Pulumi program, make sure you have installed the Pulumi CLI and set up the DigitalOcean provider by configuring the required credentials (such as a DigitalOcean token). The Kubernetes provider will also need to be set up to interact with the newly created cluster.

Here's a detailed TypeScript program that accomplishes this:

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

// Create a DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: "nyc1",
    version: "latest",
    nodePool: {
        name: "default-pool",
        size: "s-1vcpu-2gb",
        nodeCount: 2,
    },
});

// Get the kubeconfig from the created cluster
const kubeconfig = cluster.kubeConfigs[0].rawConfig;

// Create a Kubernetes provider instance using the kubeconfig
const provider = new k8s.Provider("k8s-provider", {
    kubeconfig: kubeconfig,
});

// Use the provider to deploy the standalone-authorizer helm chart
const helmChart = new k8s.helm.sh.v3.Chart("standalone-authorizer", {
    chart: "standalone-authorizer",
    version: "1.0.0", // Specify the chart version you wish to deploy
    fetchOpts: {
        repo: "https://charts.yourorg.com/", // Replace with the chart's repository URL
    },
}, { provider: provider });

// Export the cluster name and the public endpoint of the cluster
export const clusterName = cluster.name;
export const clusterEndpoint = cluster.endpoint;

```

Let's break down this program:

- We start by importing the necessary Pulumi packages.
- We create a DigitalOcean Kubernetes cluster in the specified region with `digitalocean.KubernetesCluster` resource. You can customize the region, Kubernetes version, and the size and count of the nodes according to your requirements.
- Once the cluster is created, we retrieve the kubeconfig, which is necessary for the Kubernetes provider to communicate with the cluster.
- We then instantiate a new Pulumi Kubernetes provider specifying the kubeconfig we obtained.
- With the Kubernetes provider configured, we deploy the standalone-authorizer helm chart using `k8s.helm.sh/v3.Chart`. You need to replace the `repo` and `version` with the appropriate values for the standalone-authorizer helm chart you want to deploy.

Finally, we export the cluster name and the endpoint for you to easily access them.

Remember to run `pulumi up` to create the cluster and deploy the helm chart. The `pulumi up` command will display a preview of the resources that will be created and ask for confirmation before proceeding. After confirmation, Pulumi will manage the creation of the resources in the specified order.
