1. Deploy the uoapp helm chart on Digital Ocean Kubernetes Service


    To deploy a Helm chart on Digital Ocean Kubernetes, we will use two main resources from Pulumi's Digital Ocean and Kubernetes providers:

    1. digitalocean.KubernetesCluster: This resource will be used to create a new Kubernetes cluster in Digital Ocean. A Kubernetes cluster is a set of node machines for running containerized applications. If you already have a cluster, you can skip the creation step or adapt the code to point to your existing cluster.

    2. kubernetes.helm.v3.Chart: This resource represents a Helm chart, which is a set of pre-configured Kubernetes resources. Helm charts help you define, install, and upgrade even the most complex Kubernetes applications.

    We will follow these steps in the code:

    • Define a new Kubernetes cluster in Digital Ocean.
    • Deploy the Helm chart on that cluster.

    Here is a TypeScript program that achieves this:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1: Create a new Digital Ocean Kubernetes Cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", version: "latest", // Specify your desired Kubernetes version nodePool: { name: "default-pool", size: "s-2vcpu-2gb", // Select the Droplet size nodeCount: 2, // Specify the number of Droplet instances in the node pool }, }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Step 2: Create a Kubernetes provider instance using the created cluster's kubeconfig const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Step 3: Deploy the Helm chart on the Kubernetes cluster const helmChart = new kubernetes.helm.v3.Chart("uoapp-chart", { chart: "uoapp", // Replace 'uoapp' with the name of your actual Helm chart version: "1.0.0", // Specify the version of the Helm chart // values: {}, // Add any chart values here if needed }, { provider: k8sProvider }); // Export the Helm chart status and other required outputs if necessary export const helmChartStatus = helmChart.status;

    In the program above:

    • We start by importing the necessary Pulumi packages for Digital Ocean and Kubernetes (@pulumi/digitalocean and @pulumi/kubernetes).
    • We then create a new Kubernetes cluster on Digital Ocean with the specified region, version, and Droplet size in the node pool.
    • We export the kubeconfig, which is necessary for our Kubernetes provider to interact with our Digital Ocean Kubernetes cluster.
    • We set up a Pulumi Kubernetes provider specifying the kubeconfig fetched from the newly created cluster.
    • Finally, we use the Kubernetes provider to deploy a Helm chart specifying the name and version of the chart.

    Remember to replace "uoapp" with the name of your Helm chart, and "1.0.0" with the version of the chart that you intend to deploy. If your Helm chart requires specific values, you can provide them in the values field within the helm.v3.Chart resource.

    You need to have Pulumi and the Digital Ocean CLI installed and configured. Run pulumi up to deploy the cluster and the Helm chart.

    Please note that this code assumes you're starting from scratch; if your chart is within your local file system or has specific configurations, adjustments would be needed. Furthermore, while this creates a new Kubernetes cluster for you, you could already have an existing cluster in which case certain steps to create a new cluster could be omitted.
