1. Deploy the wildcard-tls helm chart on Digital Ocean Kubernetes Service


    To deploy a Helm chart on a Digital Ocean Kubernetes Service, we will use Pulumi to define both the Kubernetes cluster on Digital Ocean and the Helm chart deployment.

    First, we need a Kubernetes cluster where the Helm chart will be deployed. We will create this using Pulumi's DigitalOcean package. The digitalocean.KubernetesCluster resource type allows us to define a Kubernetes cluster with all the necessary details like region, version, node pool configuration, etc.

    Once we have a Kubernetes cluster, we will deploy the Helm chart using the kubernetes.helm.sh/v3.Chart resource from Pulumi's Kubernetes package. This resource type allows us to deploy Helm charts from any Helm repository.

    Here's a step-by-step TypeScript program that creates the cluster and deploys the wildcard-tls Helm chart:

    import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Create a Digital Ocean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", version: "latest", // use the latest available version nodePool: { name: "default", size: "s-1vcpu-2gb", // Node size should be picked according to your workload nodeCount: 2, // Number of nodes to deploy in the node pool }, }); // Export the DigitalOcean Kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Create a new Kubernetes provider instance using the kubeconfig from DigitalOcean cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Deploy the wildcard-tls helm chart on the Digital Ocean Kubernetes cluster const wildcardTlsChart = new k8s.helm.v3.Chart("wildcard-tls", { repo: "chart-repo", // The Helm repo URL or name where the wildcard-tls chart is located chart: "wildcard-tls", values: { // Specify the values needed for the wildcard-tls Helm chart // Here is an example of setting an `key: value` pair, you will need the actual values for wildcard-tls chart someValue: "some-setting", }, }, { provider: k8sProvider }); // Export the status of Helm deployment export const helmStatus = wildcardTlsChart.status;

    In this program:

    • We create a Kubernetes cluster on Digital Ocean by defining a digitalocean.KubernetesCluster resource.
    • We then export the kubeconfig, which is a configuration file required to connect to the Kubernetes cluster.
    • We set up a Pulumi Kubernetes provider instance using this kubeconfig.
    • Next, we use a kubernetes.helm.v3.Chart resource to deploy the wildcard-tls Helm chart to the cluster we created. You'll need to replace the repo and values properties with the actual repository information and configuration values required by the wildcard-tls chart.
    • Finally, we export the status of the Helm chart deployment to observe whether it completes successfully or encounters issues.

    This program is a complete Pulumi application that will create the Kubernetes cluster and deploy your application via a Helm chart.

    Here is the documentation regarding the digitalocean.KubernetesCluster for more details on configuring your DigitalOcean Kubernetes cluster, and the Helm chart documentation provides more information on Helm chart deployment with Pulumi.

    Before running this program, please ensure that you have the @pulumi/digitalocean and @pulumi/kubernetes packages installed in your project. If you don't have them yet, you can add them using your preferred package manager:

    npm install @pulumi/digitalocean @pulumi/kubernetes

    After everything is set up, use the pulumi up command to preview and deploy your stack. Remember to check the Pulumi documentation for more information and any prerequisites needed before running the command.
