1. Deploy the rke2-coredns helm chart on Digital Ocean Kubernetes Service


    To deploy the rke2-coredns Helm chart on the Digital Ocean Kubernetes Service using Pulumi, we'll follow these steps:

    1. Create a new Digital Ocean Kubernetes cluster.
    2. Deploy the rke2-coredns Helm chart to the cluster.

    In Pulumi, we'll first need the @pulumi/digitalocean package for creating a Kubernetes cluster in Digital Ocean and the @pulumi/kubernetes package to deploy the Helm chart.

    Here’s how you can write a Pulumi program to do this:

    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", { region: "nyc1", // Set to your preferred region version: "latest", // Use the latest available version nodePool: { size: "s-2vcpu-2gb", // Choose the node size that fits your needs name: "default-pool", nodeCount: 2, // Specify the number of nodes in the pool }, }); // Step 2: Deploy the rke2-coredns Helm chart to the cluster // Create a provider to interact with your Kubernetes cluster const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy the rke2-coredns Helm chart const helmChart = new kubernetes.helm.v3.Chart("rke2-coredns", { chart: "rke2-coredns", // You may need to specify the repository where rke2-coredns is located // For example: // repositoryOpts: { // repo: "https://helm.rancher.io/" // }, values: { // Provide any custom configurations you want to apply // For example: // replicaCount: 2 }, }, { provider: k8sProvider }); // Export the cluster name and kubeconfig export const clusterName = cluster.name; export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

    This program performs the following actions:

    • Digital Ocean Kubernetes Cluster: Creates a new Kubernetes cluster in your specified region with the name do-cluster. We're choosing a small node size for demonstration purposes, and starting with 2 nodes.

    • Provider Configuration: Sets up a Pulumi Kubernetes provider to interact with your new Kubernetes cluster, using the kubeconfig that is retrieved from the Digital Ocean Kubernetes cluster.

    • Helm Chart: Deploys the rke2-coredns Helm chart using the Pulumi Kubernetes provider. You need to specify the repository where the Helm chart is hosted. Optionally, you can provide a values object to override default chart values with the configurations you desire.

    After setting this up, run pulumi up to execute it. Pulumi will provision the resources in the defined order. The process will result in your Kubernetes cluster being deployed on Digital Ocean and the rke2-coredns Helm chart being applied to that cluster.

    Remember that before running the program with Pulumi CLI, you need to set up your Pulumi stack and authenticate with Digital Ocean so that Pulumi can create and manage resources in your DO account.

    Also, replace the chart and repositoryOpts values with accurate ones for rke2-coredns if necessary (the given values are placeholders as I don't have access to the exact repository details).

    Please notice the correct versions and settings might change based on your specific requirements and the current offerings by Digital Ocean and updates to the Helm charts you want to use. Check the official documentation of Digital Ocean and the Helm chart for rke2-coredns for the latest information.
