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


    To deploy the Kraken Helm chart on the DigitalOcean Kubernetes Service (DOKS), we will perform a series of steps using Pulumi with TypeScript as our language choice. I will guide you through the steps and explain the code and the resources involved.

    The process can be broken down into the following steps:

    1. Provision a DigitalOcean Kubernetes cluster.
    2. Deploy a Helm chart for Kraken onto the cluster.

    To begin, we will provision a new Kubernetes cluster on DigitalOcean using Pulumi's digitalocean package. The KubernetesCluster resource is responsible for creating and configuring the cluster on DigitalOcean. Once we have our cluster up and running, we'll deploy the Kraken Helm chart using Pulumi's kubernetes package, which allows us to deploy Helm charts on Kubernetes clusters.

    Here is the TypeScript program that performs both steps:

    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: "nyc1", // Replace with your preferred region version: "latest", // Use the latest available version nodePool: { name: "default", size: "s-2vcpu-2gb", // Choose the size that fits your needs nodeCount: 2, // Specify the number of nodes you want }, }); // Step 2: Deploy the Kraken Helm chart onto the cluster // First, we need to create a Kubernetes provider instance configured to the newly created cluster. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Use the Helm chart resource from the Pulumi Kubernetes provider to deploy Kraken const krakenChart = new k8s.helm.v3.Chart("kraken", { chart: "kraken", // Name of the chart version: "0.1.0", // Specify the version of the chart fetchOpts: { repo: "https://charts.example.com/", // Replace with the Helm repository URL containing the Kraken chart }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and the service endpoint of the Kraken release export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const krakenServiceEndpoint = krakenChart.getResourceProperty("v1/Service", "kraken", "status");

    In this program:

    • We create a DigitalOcean Kubernetes cluster with a name do-cluster. You can customize the region, version, size, and nodeCount based on your preferences and requirements.
    • The KubernetesCluster resource automatically generates a kubeconfig which we can use to interact with the cluster.
    • We define a k8s.Provider, which is the Pulumi Kubernetes provider, to interact with our Kubernetes cluster using the aforementioned kubeconfig.
    • We deploy the Kraken Helm chart using the Chart resource of the k8s.helm.v3 module in Pulumi. We specify the chart name (kraken), the chart version, and the repository where the chart is located. Ensure you replace https://charts.example.com/ with the actual repository URL.

    Finally, we export the kubeconfig and the service endpoint to connect and interact with the deployed Kraken application.

    Before running this code, ensure you have set up Pulumi, have the Pulumi CLI installed, and the DigitalOcean access token configured in Pulumi.

    Once you've confirmed that everything is properly set up, you can run this Pulumi program with the Pulumi CLI commands:

    • pulumi up to create or update resources
    • pulumi destroy to clean up all resources
    • pulumi stack output to see the exported outputs (like the kubeconfig and service endpoint)
