1. Deploy the servicemesh-k8ssandra-resource helm chart on Digital Ocean Kubernetes Service


    To deploy the servicemesh-k8ssandra-resource helm chart on the DigitalOcean Kubernetes Service using Pulumi, you'll need to follow these steps:

    1. Setting up DigitalOcean Kubernetes Cluster:
      • First, you need to create a Kubernetes cluster in DigitalOcean where your helm chart will be deployed. This is done by using the digitalocean.KubernetesCluster resource.
    2. Deploying Helm Chart:
      • Once the Kubernetes cluster is ready, you will use the kubernetes.helm.v3.Chart resource to deploy the servicemesh-k8ssandra-resource helm chart onto the cluster. This Pulumi resource manages the Helm chart's deployment just as helm CLI does but through Pulumi's infrastructure as code approach.

    Here is a step-by-step TypeScript program that accomplishes this:

    import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as k8s from '@pulumi/kubernetes'; import * as random from '@pulumi/random'; // Generate a strong password for the Kubernetes cluster, you may also define it explicitly. const password = new random.RandomPassword("password", { length: 16, special: true, }).result; // Create a DigitalOcean Kubernetes Cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: digitalocean.Regions.NYC1, // Choose the region that is closest to you or your users version: "1.21.5-do.0", // Use the version that suits your needs nodePool: { name: "default", size: digitalocean.DropletSlugs.DropletS2VCPU2GB, // Choose the size that fits your expected workload nodeCount: 1, // Start with 1 node, can be scaled as needed }, }); // Get the kubeconfig from the created DigitalOcean Kubernetes Cluster const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Create a provider for the above Kubernetes cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Define the servicemesh-k8ssandra-resource Helm chart and its release. const chartName = "servicemesh-k8ssandra-resource"; const servicemeshChart = new k8s.helm.v3.Chart(chartName, { chart: chartName, version: "0.1.0", // Specify the exact chart version you want to deploy // Values for the Helm chart are set according to your needs. values: { service: { type: "ClusterIP", }, // Add any other required values here }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and the Helm chart status export const kubeconfigOutput = pulumi.secret(kubeconfig); export const isHelmChartDeployed = servicemeshChart.status; // Access the cluster using kubectl or any other K8s management tool with the exported `kubeconfig`.


    • We first import the necessary Pulumi packages for interacting with DigitalOcean, Kubernetes resources, and generating random passwords.
    • A DigitalOcean Kubernetes cluster is created via digitalocean.KubernetesCluster, provisioning it in the region NYC1 with the Kubernetes version 1.21.5-do.0, inside which the helm chart will be deployed.
    • We retrieve the kubeconfig of the created Kubernetes cluster which is needed to communicate with the cluster.
    • A Pulumi Kubernetes provider k8s.Provider is instantiated to use the kubeconfig, enabling Pulumi to deploy resources onto that cluster.
    • We define the helm chart deployment using the k8s.helm.v3.Chart class, providing it the chartName, the chart version, and custom values that might be necessary for the chart deployment, all in the context of the created Kubernetes provider.
    • Finally, we export the computed Kubernetes kubeconfig and the helm chart deployment status for use outside of Pulumi.

    Next Steps:

    • Install Pulumi and set up your Pulumi account.
    • Install Node.js and the Yarn package manager.
    • Set up doctl, the DigitalOcean command-line tool, and authenticate it with your DigitalOcean account.
    • Create a new Pulumi TypeScript project and add the above code in the index.ts file.
    • Run pulumi up to execute the Pulumi code and deploy the Kubernetes cluster and helm chart.
    • Use the exported kubeconfig to interact with your cluster via kubectl or any Kubernetes management tools.
