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


    To deploy a Helm chart on Digital Ocean Kubernetes Service using Pulumi, you will need to follow these steps:

    1. Create a Kubernetes Cluster: Use the digitalocean.KubernetesCluster resource to provision a new Kubernetes cluster on Digital Ocean.
    2. Install the Helm Chart: After the Kubernetes cluster is provisioned, use the kubernetes.helm.sh/v3.Chart resource to deploy your Helm chart onto the cluster.

    Here is a detailed Pulumi program written in TypeScript that demonstrates how to accomplish 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", { // Define the region where the cluster will be created. region: digitalocean.Regions.NYC3, // Specify the version of Kubernetes to use. version: "1.21.5-do.0", // Specify the node pool configuration. nodePool: { // Set the size of the pool's nodes, which defines the virtual hardware to which your workloads // will be scheduled. Choose a size based on the resources needed by your specific workloads. size: digitalocean.DropletSlugs.DropletS2VCPU2GB, // Set the number of nodes in this pool. nodeCount: 2, // Optionally add tags that can be used to manage and filter resources. tags: ["kube-cluster"], }, }); // Step 2: Deploy the Datadog Helpers Helm chart. const datadogHelpersChart = new kubernetes.helm.sh/v3.Chart("datadog-helpers", { // Specify the Kubernetes provider using the cluster kubeconfig. // This tells Pulumi to install the Helm chart into this specific cluster. provider: new kubernetes.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }), // Specify the repository and the Helm chart along with the version. chart: "datadog_helpers", version: "1.0.0", // Replace with the desired version of your chart. fetchOpts: { repo: "http://datadog.github.io/helm-charts", // Use the correct Helm repository URL. }, // Specify any values needed for the Helm chart. // These values are used to configure the deployed chart. values: { // Place your configuration values here. }, }, { dependsOn: cluster }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeConfigs[0].rawConfig;


    • DigitalOcean Kubernetes Cluster: We start by creating a Digital Ocean Kubernetes cluster using digitalocean.KubernetesCluster (Docs). We specify the region, Kubernetes version, node hardware size, and quantity here.
    • Kubernetes Provider: We setup a Kubernetes provider that specifies the cluster onto which Pulumi will deploy resources. We utilize the kubeconfig from the newly created Digital Ocean Kubernetes cluster for this.
    • Helm Chart: We deploy a Helm chart named datadog_helpers with kubernetes.helm.sh/v3.Chart (Docs). We specify the chart information, including the appropriate Helm repository and the version of the chart you wish to deploy. Remember, the values property is where you define your customized values depending on the Helm chart requirements.

    Once you have this Pulumi program, make sure to install the required Node.js dependencies using npm:

    npm install @pulumi/digitalocean @pulumi/kubernetes @pulumi/pulumi

    When your Pulumi program is ready, deploy it with the following commands:

    pulumi up

    This will provision the Kubernetes cluster and deploy the datadog_helpers Helm chart to your Digital Ocean Kubernetes cluster. The kubectl context will be set, allowing you to interact with your Kubernetes cluster using kubectl commands if needed. The kubeconfig needed to access your cluster is also exported, which you can use in any Kubernetes management tool or CLI.
