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


    To deploy a Helm chart on the Digital Ocean Kubernetes Service (DOKS) using Pulumi, you will need to perform the following steps:

    1. Set up a Digital Ocean Kubernetes cluster.
    2. Install Helm and add the chart repository containing the "whitelist" Helm chart.
    3. Deploy the Helm chart on the cluster.

    We will use Pulumi's DigitalOcean and Kubernetes providers to accomplish this. First, we establish a new Kubernetes cluster in DigitalOcean, then we deploy the Helm chart to that cluster.

    Below is a program written in TypeScript that demonstrates how to do this with Pulumi:

    import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create a new DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", version: "latest", nodePool: { name: "default", size: "s-2vcpu-2gb", nodeCount: 1, }, }); // Step 2: Use Pulumi to get the kubeconfig from the DOKS cluster we created const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Step 3: Create a Kubernetes provider instance using the kubeconfig from DOKS const k8sProvider = new k8s.Provider("do-k8s", { kubeconfig: kubeconfig, }); // Step 4: Deploy the whitelist Helm chart to the DOKS cluster const whitelistChart = new k8s.helm.v3.Chart("whitelist-chart", { chart: "whitelist", // Specify the repository where the Helm chart is located fetchOpts: { repo: "http://charts.yourcompany.com/", // Replace with Helm chart repository URL }, }, { provider: k8sProvider }); // Export the kubeconfig and public endpoint to access the cluster export const kubeconfigOutput = kubeconfig; export const clusterEndpoint = cluster.endpoint;

    Here's what each piece of the program does:

    • We import the DigitalOcean and Kubernetes packages from Pulumi.
    • We declare a new Kubernetes cluster on DigitalOcean with the desired configuration. The region specifies where to locate the cluster, version assigns the Kubernetes version to use, and nodePool defines the attributes of the node pool.
    • We obtain the kubeconfig from the new DigitalOcean Kubernetes cluster, making it possible to interact with the cluster via the Kubernetes API.
    • We create a Pulumi Kubernetes provider that uses our kubeconfig, which allows Pulumi to deploy resources to our DigitalOcean Kubernetes cluster.
    • We declare a Helm chart resource using the Pulumi Kubernetes provider, specifying the Helm chart's name and the repository URL where the Helm chart can be found. This Helm chart is assumed to be named "whitelist" in the repository. Replace http://charts.yourcompany.com/ with the actual repository URL where the "whitelist" Helm chart is stored.
    • We export the kubeconfig and the cluster's public endpoint as outputs. These can be used to interact with the Kubernetes cluster using tools like kubectl.

    This program assumes that you have a Helm chart named "whitelist" stored in a Helm repository. Modify the repo property with the correct URL of your Helm chart repository.

    To run this Pulumi program, you will need to install Pulumi and set up your DigitalOcean token. Once configured, you can run pulumi up to deploy the resources described above. If you've not added the whitelist Helm chart to a repository, you'll need to do that first before running this program.

    Keep in mind that the latest version of Kubernetes specified in the cluster properties might need to be replaced with a more specific version supported by DigitalOcean at the time of deployment.
