1. Deploy the ucloud-exporter helm chart on Digital Ocean Kubernetes Service


    To deploy the ucloud-exporter helm chart on the Digital Ocean Kubernetes Service using Pulumi, you would first need to create a Kubernetes cluster within Digital Ocean. Then, once the cluster is set up, you can deploy the helm chart to the newly created Kubernetes cluster.

    Here's a step-by-step breakdown of what we are going to do:

    1. Set up a new Digital Ocean Kubernetes Cluster: Using Pulumi's Digital Ocean provider, we will create a Kubernetes cluster within your Digital Ocean account.
    2. Install the ucloud-exporter Helm Chart: After the Kubernetes cluster is provisioned, we would use the Pulumi Kubernetes provider to install the ucloud-exporter helm chart into the cluster.

    Let's start with the Pulumi program that will set this up.

    import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Creating a DigitalOcean Kubernetes Cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", // Choose the region that is best for you version: "latest", // Specify the desired Kubernetes version nodePool: { name: "default-pool", size: "s-2vcpu-2gb", // This is the smallest size available nodeCount: 2, // Specify the number of nodes in the NodePool }, }); // Step 2: Using the resulting Kubeconfig from the cluster to create a K8s provider const k8sProvider = new k8s.Provider("do-k8s", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Install ucloud-exporter using Helm Chart const ucloudExporterChart = new k8s.helm.v3.Chart("ucloud-exporter", { chart: "ucloud-exporter", // Make sure to replace `repoURL` with the actual repository URL of the helm chart // and `chartVersion` with the desired version you want to install. fetchOpts: { repo: "https://helm-repo-url-here/", }, version: "chartVersion", }, { provider: k8sProvider }); // Export the cluster's kubeconfig and endpoint export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const clusterEndpoint = cluster.endpoint;

    Breaking down the above program:

    • Digital Ocean Kubernetes Cluster: The digitalocean.KubernetesCluster resource creates a Kubernetes cluster. This cluster is placed in the nyc1 region with the latest Kubernetes version. It sets up a node pool with two nodes of a small size to run your workloads.

      • You can change the region, version, size, and nodeCount as per your need.
    • Kubernetes Provider: The k8s.Provider instance is responsible for interpreting the kubeconfig and setting up communication with the Kubernetes cluster we just created. It relies on the kubeConfigs output of the Digital Ocean Kubernetes cluster.

    • Helm Chart: Using the k8s.helm.v3.Chart resource, we deploy the ucloud-exporter helm chart to our Kubernetes cluster. Adjust the repo property to point to where your helm chart is hosted and specify the version of the chart you wish to install.

    • Exports: Finally, we export the kubeconfig and clusterEndpoint for your use to interact with the Kubernetes cluster manually if required.

    Remember to replace the placeholder "https://helm-repo-url-here/" with the actual URL of the helm chart repository that hosts ucloud-exporter and specify the chartVersion you want to deploy.

    Make sure you have Pulumi CLI installed and configured with your Digital Ocean token before running this program. Save this TypeScript code in a file (e.g., index.ts), then run pulumi up to create and deploy your cluster and your Helm chart.

    Please note that provisioning a Kubernetes cluster and deploying a chart might take some time, so be patient while Pulumi works on setting up the resources. Once done, you'll have a running instance of ucloud-exporter on a Digital Ocean Kubernetes cluster!
