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


    Sure, deploying an application using a Helm chart on a Kubernetes cluster hosted by Digital Ocean is a multi-step process that involves:

    1. Provisioning the Kubernetes cluster on Digital Ocean
    2. Configuring kubectl to interact with the newly created cluster
    3. Deploying the application using the Helm chart

    Below is a program written in TypeScript that:

    • Sets up a Digital Ocean Kubernetes cluster
    • Configures kubectl to interact with that cluster
    • Deploys a Helm chart (assumed to be named "magnum") onto the cluster

    Please make sure you have Pulumi and Helm installed on your local machine, and your Digital Ocean access token is set up in the Pulumi stack configuration or available as an environment variable.

    Here's a detailed Pulumi program for your request:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Create a Digital Ocean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { // Specify the region where the cluster is to be created region: digitalocean.Regions.NYC1, // Select the version of Kubernetes to use version: "latest", // Define the node pool configuration nodePool: { name: "default", size: digitalocean.DropletSlugs.DropletS2VCPU2GB, nodeCount: 2, // Specify the desired number of nodes }, }); // Step 2: Configure kubectl to connect to the new cluster // Note: This example uses the kubernetes provider to interact with the created cluster const k8sProvider = new kubernetes.Provider("do-k8s", { kubeconfig: cluster.kubeConfigs[0].rawConfig, // Use the generated kubeconfig to authenticate kubectl }); // Step 3: Deploy the magnum helm chart using the kubernetes provider const chart = new kubernetes.helm.v3.Chart("magnum", { chart: "magnum", version: "1.0.0", // Replace with the desired chart version fetchOpts: { repo: "http://example.com/helm-charts", // Specify the Helm chart repository URL here }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Export the endpoint of the deployed Helm chart service, if applicable export const chartServiceEndpoint = chart.getResource("v1/Service", "default", "magnum").status;


    1. We import the necessary Pulumi packages for Digital Ocean and Kubernetes.
    2. We create a new Digital Ocean Kubernetes cluster in a specific region with a specified Kubernetes version and node pool size. Adjust these parameters based on your needs.
    3. We create a Pulumi Kubernetes provider to interact with the cluster using the kubeconfig that is generated when the Digital Ocean cluster is created.
    4. We deploy a Helm chart named "magnum," which we need to fetch from a Helm repository (ensure to replace the example repository URL with the actual URL of your Helm chart). The Helm chart version is specified for precision in deployments.
    5. We export the kubeconfig so you can interact with the Kubernetes cluster using kubectl directly if needed.
    6. We export the service endpoint of the chart, assuming it creates a Service of type LoadBalancer or NodePort, allowing you to interact with the deployed application.

    Remember to replace placeholders with actual values like Helm repository URL and chart version. This program assumes you already have an account with Digital Ocean and have the necessary credentials configured for Pulumi.
