Full Code Example

import * as pulumi from "@pulumi/pulumi";
import * as digitalocean from "@pulumi/digitalocean";

// Create a DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("my-cluster", {
    region: "nyc1",
    version: "1.21.5-do.0",
    nodePool: {
        name: "default-pool",
        size: "s-1vcpu-2gb",
        nodeCount: 3,
    },
});

// Export the kubeconfig
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;
