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

    TypeScript

    To deploy the aliyun-exporter Helm chart on Digital Ocean's Kubernetes Service (DOKS) using Pulumi, it essentially involves two main steps:

    1. Provision a Kubernetes cluster on Digital Ocean.
    2. Deploy the aliyun-exporter Helm chart to the cluster.

    Below is a detailed breakdown of the program that accomplishes this. In this program, we are using the digitalocean and kubernetes Pulumi packages for creating the Kubernetes cluster and deploying the Helm chart respectively.

    First, we need to create a Kubernetes cluster on Digital Ocean. The digitalocean.KubernetesCluster resource from the @pulumi/digitalocean package is used for this purpose. You can define the size and number of nodes in the cluster, as well as region and version specifications.

    After provisioning the cluster, we'll then obtain the kubeconfig which will be used by Pulumi to interact with our Kubernetes cluster.

    Finally, once the cluster is available, we will deploy the aliyun-exporter Helm chart using the kubernetes.helm.v3.Chart resource from the @pulumi/kubernetes package. This is a generic resource that allows us to deploy Helm charts to a Kubernetes cluster.

    Please ensure you have Pulumi installed and configured to use with your Digital Ocean token, and you have both pulumi and kubectl command line tools installed.

    Here's the program that performs the above steps:

    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("pulumi-k8s-cluster", { // The region for the Kubernetes cluster, SFO2 for example is San Francisco 2. region: digitalocean.Regions.SFO2, // The size of the Droplet to use as workers. nodePool: { size: digitalocean.DropletSlugs.DOS3VCPUAnd1GB, name: "default", // The number of Droplet instances to create in the node pool. nodeCount: 2, }, // The slug identifier for the version of Kubernetes to use. version: digitalocean.getKubernetesVersions().then(p => p.latestVersion), // Automatically select the latest version. }); // Export the DigitalOcean Kubernetes cluster Kubeconfig. export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Set up a provider to use the generated kubeconfig so that we can deploy resources to our cluster. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Deploy the `aliyun-exporter` Helm chart onto the Kubernetes cluster const aliyunExporter = new k8s.helm.v3.Chart("aliyun-exporter", { chart: "aliyun-exporter", version: "1.0.0", // Use the version number that is applicable. // Assuming the chart is publicly available in a Helm repository, otherwise configure the 'repo' property. fetchOpts: { repo: "https://helm-repository-url/where/chart/is/located/", }, }, { provider: k8sProvider }); // To verify, you can deploy this program using Pulumi CLI commands: `pulumi up`

    Please replace the chart, version, and fetchOpts.repo properties with the correct values for the aliyun-exporter chart.

    In kubeconfig we are exporting the raw Kubernetes cluster configuration, which can be used to connect to the cluster with kubectl on your local machine.

    In the k8sProvider, we specify that we would like to use the kubeconfig of the cluster we just created to deploy resources to it.

    The aliyunExporter resource deploys the Helm chart onto the cluster provided by k8sProvider. The name '1.0.0' is a placeholder for the version of the aliyun-exporter chart you wish to use. Similarly, the fetchOpts.repo URL should point to the repository where the aliyun-exporter chart is hosted.

    Remember to follow the Pulumi project setup instructions, including setting up your Pulumi stack, installing necessary packages, and configuring authentication for Digital Ocean and the Kubernetes cluster. Use the Pulumi CLI to deploy this program with the pulumi up command.
