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


    Deploying a Helm chart to a Kubernetes cluster involves a few distinct steps:

    1. Provisioning the Kubernetes cluster
    2. Installing the Helm CLI tool locally or on a CI/CD system (this step is typically not managed by Pulumi and is executed from a shell)
    3. Using Pulumi to configure and deploy a Helm chart onto the cluster

    Below, I'll provide you with a Pulumi program that provisions a DigitalOcean Kubernetes cluster and then deploys the "vps" Helm chart to that cluster.

    Firstly, we need to create a new DigitalOcean Kubernetes cluster. Pulumi's digitalocean package contains the KubernetesCluster resource, which makes it straightforward to do so.

    After creating the cluster, we will use the helm.sh/v3.Chart resource from the kubernetes package to deploy the Helm chart. I will assume that you already have the "vps" Helm chart information, such as the repository URL where it's stored and the version you wish to deploy.

    The following TypeScript program will:

    1. Provision a DigitalOcean Kubernetes cluster.
    2. Deploy the "vps" Helm chart to the newly provisioned Kubernetes cluster.

    Make sure to replace the placeholder values (like <YOUR-CLUSTER-NAME>, <REGION>, <NODE-SIZE>, and <HELM-CHART-VERSION>) with your specific details.

    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: "<REGION>", // Specify the region (e.g., "nyc3") version: "<K8S-VERSION>", // Specify the version of Kubernetes (e.g., "1.18.8-do.1") nodePool: { name: "default", size: "<NODE-SIZE>", // Specify the size of the nodes (e.g., "s-2vcpu-2gb") nodeCount: 2, // Specify the number of nodes }, }); // Export the DigitalOcean Kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Create a K8s Provider instance using the kubeconfig from the cluster we just created const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Deploy the "vps" Helm chart const vpsChart = new k8s.helm.v3.Chart("vps-chart", { chart: "vps", version: "<HELM-CHART-VERSION>", // Specify the chart version fetchOpts: { repo: "<HELM-CHART-REPOSITORY>", // Specify the Helm chart repository URL }, }, { provider: k8sProvider }); // Export the Kubernetes cluster name and Helm chart deployment status export const clusterName = cluster.name; export const vpsChartStatus = vpsChart.status;

    Here's what each part of the program does:

    • The digitalocean.KubernetesCluster resource creates a new Kubernetes cluster in your specified DigitalOcean region and with the specified settings.
    • kubeconfig is exported so that you can use it with kubectl locally to interact with your cluster once it is provisioned.
    • The k8s.Provider resource initializes the Kubernetes provider with the kubeconfig, making it possible to deploy Kubernetes resources.
    • The k8s.helm.v3.Chart resource represents the Helm chart that we want to deploy. Here we assume that the vps chart is publicly available in a Helm repository; you specify the chart name, version, and repository URL.
    • Finally, we export some of the resulting state: the name of the Kubernetes cluster and the status of the Helm chart deployment.

    Please replace the placeholder variables with the actual values you want to use. Once done, run the Pulumi program by executing pulumi up in the command line where your Pulumi program is saved.

    Before you run the program, ensure:

    • You have the Pulumi CLI installed.
    • You are logged in to your Pulumi account using pulumi login.
    • You have set up DigitalOcean provider credentials on your system.
    • You have Helm CLI installed if you want to manage Helm releases apart from what Pulumi does.

    Keep in mind that you need to have the appropriate permissions set in DigitalOcean and any necessary firewall rules configured to access the deployed services from the internet if that's required.
