1. Deploy the tailscale-subnet-router helm chart on Digital Ocean Kubernetes Service


    To deploy the Tailscale subnet router Helm chart on a Digital Ocean Kubernetes cluster using Pulumi, you will first need to create a Kubernetes cluster in Digital Ocean. Once the cluster is up and running, you'll utilize Helm to deploy the Tailscale subnet router onto it. Below, I'll walk you through the steps with a detailed explanation and then provide you with the TypeScript program to accomplish this.

    1. DigitalOcean KubernetesCluster resource is used to create a managed Kubernetes cluster on Digital Ocean. You'll need to specify the region, version, and node pool configuration. This sets up the infrastructure where your Tailscale subnet router will be deployed.

    2. Helm Chart resource is used to deploy applications on Kubernetes using Helm charts. We'll utilize this resource to deploy the Tailscale subnet router Helm chart. You'll need to specify the Helm chart details such as name, version (if required), and any custom values you may wish to apply.

    Here is the TypeScript program that achieves this:

    import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as kubernetes from '@pulumi/kubernetes'; // Step 1: Create a new DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster('do-cluster', { // Specify the region for the cluster region: digitalocean.Regions.NYC1, // Define the Kubernetes version version: 'latest', // Use the latest available version // Define the node pool where the workloads will be scheduled nodePool: { // Unique name for the node pool name: 'default-pool', // Droplet size for the nodes in the pool size: digitalocean.DropletSlugs.DropletS2VCPU2GB, // Number of nodes in the pool nodeCount: 2, }, }); // Step 2: Use the DigitalOcean Kubernetes cluster with the Pulumi Kubernetes provider const k8sProvider = new kubernetes.Provider('k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Install the Tailscale Subnet Router helm chart const tailscaleChart = new kubernetes.helm.v3.Chart('tailscale-subnet-router', { // Define the chart repository and name chart: 'tailscale', // Specify the namespace to install the chart into namespace: 'default', // Specify any additional values needed by the chart values: { // This should be filled with any required values for the Tailscale chart }, // Reference the previously created DigitalOcean Kubernetes cluster's provider fetchOpts: { repo: 'https://helm.tailscale.com', }, }, { provider: k8sProvider }); // Export the K8s cluster name and the Kubeconfig to access the cluster export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const clusterName = cluster.name;

    This program begins by importing the required modules. We then create a new Kubernetes cluster on Digital Ocean with a specified region, Kubernetes version, and a node pool configuration. After the cluster is up and running, we create a new instance of the Pulumi Kubernetes provider, passing the generated kubeconfig of our Digital Ocean cluster. Then we deploy the Tailscale subnet router Helm chart, specifying the chart details and namespace into which it will be deployed.

    After applying this Pulumi program with pulumi up, you'll have a Kubernetes cluster running on Digital Ocean with the Tailscale subnet router Helm chart installed. The exports at the end of the file provide you with the necessary details to access your Kubernetes cluster.
